Fixing Warning: the ECDSA host key for 'github.com' differs from the key for the IP address

Kevin Wentworth — Sun, 10 Sep 2023 07:01:00 +0100

Host Key Differs Warning from Github When you run git fetch and you get this warning: Warning: the ECDSA host key for 'github.com' differs from the key for the IP address '140.82.114.3' Offending key for IP in /username/.ssh/known_hosts:7 Matching host key in /username/.ssh/known_hosts:9 This is a pretty simple fix: ssh-keygen -R github.com ssh-keygen -R 140.82.114.3 You may have to do this more than once depending on how many different IP address are cached in your known_hosts file

CakePHP 3 - Getting List of Column Definitions from a Table (like schema())

Kevin Wentworth — Wed, 26 Dec 2018 14:48:00 +0100

You may come from a time when using $this->ModelName->schema() would give you the details of a table's column defintions. Not in CakePHP 3. I found this manual way of achieving the same thing: // insert into begin of the controller file use Cake\Datasource\ConnectionManager; $db = ConnectionManager::get('default'); // Create a schema collection. $collection = $db->schemaCollection(); // Get a single table (instance of Schema\TableSchema) $tableSchema = $collection->describe('articles');...

Change Order of Loaded Behaviors in CakePHP 3

Kevin Wentworth — Fri, 14 Sep 2018 09:33:00 +0100

Turns out it's really easy to change the order of how behaviors are loaded in CakePHP 3. Wait, I'm actually sort of lying. You can't change the order of loaded behaviors. (BOO!). In previous versions of Cake this was a problem... however, with the fully implemented Events subsystem in Cake3, all you need to do is change the priority of the behavior callbacks. What's that, you say? Change Order of Behaviors in Cake3 You actually don't need to worry about the order that behaviors are...

CakePHP 3 - Accept JSON Header Only Working When Debug False

Kevin Wentworth — Tue, 29 May 2018 09:20:00 +0100

Strange thing... when you have debug disabled you may find that your application works fine when dealing with json routes without the extension. Instead of accessing /posts.json, you would access /posts and send an Accept: application/json header and the same thing is achieved. Debug On - Json View Templates Don't Load - Same Accept Header I came across this issue , which seems to imply that if you want the application/json Accept header to be properly parsed, you need to enable router...

Remove All Events from Google Calendar (Reset Calendar)

Kevin Wentworth — Wed, 23 May 2018 21:29:00 +0100

I've been doing a lot of programming with the Google Calendar API lately and ran into an issue when I was ready to "go live" with the site. The Google Calendar was loaded with tons of test data! I searched around and found plenty of sites giving the same answer. The problem with the answer- it was incomplete. If you want to reset a calendar (a Google Calendar factory reset of sorts) you need to permanently delete all calendar events using calendar settings, but also you need to empty the...

Google Tag Manager (GTM) Not Firing Default PageView Event

Kevin Wentworth — Wed, 08 Nov 2017 12:21:00 +0100

We had an interesting issue here today regarding Google Tag Manager not firing the default PageView event. Instead it was firing the /gtm.js event. WTF?! Turns out, the system we were using was reading event: 'gtm.js' in the GTM container snippet as a link to a javascript resource. So, it was turning the "url" into an absolute path, like so: event: '/gtm.js'. Google Tag Manager doesn't know what to do with an event named "/gtm.js" How were we going to solve this? A little ASCII magic...

Getting output from shell_exec() at all times

View Layer - Getting count of Entities in View in Cakephp 3

Kevin Wentworth — Sun, 12 Jun 2016 13:27:00 +0100

In my views I'm usually executing code depending on if a variable is empty or not. For example, I'll fetch all the images in a gallery and only want to output the containing divs when the gallery has images. You can't do a simple !empty() or if($img) because it will always be "true" because it will be a non-empty object (like Cake\ORM\Query or similar). So, if you want to find out if a variable (at the view level) is empty or not, use the isEmpty() function. Is that variable empty?...

Changing URL in beforeRedirect() in Component - Cakephp 3

Change the URL redirect location using beforeRedirect() in Cakephp 3 I wanted to change the redirect behavior from within a component in my Cakephp 3 application. The old 1.3 method of returning the new $url didn't work. Turns out that you need to use Response::location() to modify the location of the redirect. See my code below: public function beforeRedirect(Event $event, $url, Response $response) { // need to reload the same page $response->location($this->request->here); return; }...

You can change what view.ctp file you want to use in your controller with the following line of code. I place it at the bottom of my function definition. Useful for having a simple admin interface or a different view template for each language. This doesn't change the layout of your page, just the view template the controller uses when rendering your content. $this->viewBuilder()->template('another_view'); // will use another_view.ctp instead of controller_name.ctp Cheers,...

Debugging 500 errors

Kevin Wentworth — Wed, 25 Jun 2014 14:04:00 +0100

500 errors are notoriously vague errors that can occur for a number of reasons. Technically the 500 error is defined as an internal server error. This does not tell you much but it does tell you that you NEED MORE INFORMATION. How you get that information is from your error logs. You may look in your application error logs but they will not contain PHP and Apache errors. Because it is Apache that throws the 500 error, you should start by looking at the apache logs. In WHM/Cpanel/CentOS...

Kevin Wentworth — Sun, 21 Oct 2012 10:27:00 +0100

I avoided PNG images for quite a while, mainly because I could accomplish almost every task with transparent GIFs (if not, I could change the design ever so slightly). Fast forward a few years and web designs are far too complex and textured to only use transparent GIFs, plus it's so much cooler to say "ping" than "gif". Another reason I avoided using transparent PNGs was due to the ability to make IE (Internet Explorer) crash (suprise!). Finally, I avoided using PNG images on my website...

CakePHP Form Security Blackhole on Large Forms

Kevin Wentworth — Thu, 28 Jun 2012 11:11:00 +0100

I kept getting the White Screen of Death (WSOD). What we at Saco Design have appropriately named the behavior of the default blackhole Security Component setting. The weird issue was that I was getting the issue only on the live server. I had recently updated the live server's version of PHP to the latest 5.3.x release. However, I neglected to update my local PHP version, which was still 5.3.5. max_input_vars I was looking through the php.ini file to see if there were any settings...

Calling an Element from a Helper

Kevin Wentworth — Fri, 24 Feb 2012 14:07:00 +0100

This one caused me more than a little headache, turned out it was easily solvable. renderElement() can be used in a helper function. The following example worked nicely for me. In this case I am calling and element "order_form.ctp" $theView = ClassRegistry::getObject('view'); echo $this->output($theView->renderElement('order_form'));

Forcing A Single Join in CakePHP Pagination

Kevin Wentworth — Fri, 14 Oct 2011 09:25:00 +0100

The devil's in the details... I was trying to make a really simple, dreadfully easy, database join in my CakePHP web application. I've forced joins in Cake before, using the 'joins' key in the options array for find calls and paginate calls with no issue. It was late and for the first time I only wanted to use a single join. I copied the join code from a much more complex web app and pasted it into my new 'joins' conditions. And then... I got SQL errors. That query doesn't look...

Inserting NOW() into MySQL Using CakePHP

Kevin Wentworth — Thu, 11 Aug 2011 23:16:00 +0100

Great find. If you want to insert NOW() into your query using CakePHP's save() or saveAll() functions, you can use the following expression: $this->data['Model']['custom_date_field'] = DboSource::expression('NOW()'); Not sure how it works on MSSQL, but I will be testing that soon. Cheers, -Kevin Wentworth

Best PaginateCount for CakePHP - with Group By Support

Kevin Wentworth — Sun, 07 Aug 2011 17:03:00 +0100

I'm been muddling my way through pagination with multiple joins, and complex filtering. I finally got it all working (more on that later, maybe....) when I noticed that I couldn't paginate my results. Everything was working fine until I added a "group" parameter to the find call. Instead of getting the right count, I got a count of 1! A quick look at my sql log tables (at the bottom of the page) and I saw that I had actually returned all the mysql records that were needed! If only there...

CakePHP Error Messages Not Showing on Form

Kevin Wentworth — Sun, 03 Apr 2011 12:40:00 +0100

I ran into an issue today that I've run into before, except I couldn't remember what I did to fix it (hence this article). I was using CakePHP validation rules to validate a user account details. The CakePHP validation was properly failing (the form data wasn't being saved) and I could tell the validate array was set correctly because the required fields were having the class .required added to them. The only problem? No error messages were being output to the form. The form validation...

Sorting Paginated Results Using a Related Model Field in CakePHP

Kevin Wentworth — Sun, 06 Feb 2011 22:12:00 +0100

Time crunch, so this will be quick. I didn't want to go hunting for how to sort paginated results in CakePHP using a related model field again. I actually found my answer on Stack Overflow. The original poster had it right, so I'm not sure if it was a CakePHP bug or what (I don't have an account or I would correct it... it's on the list of to-dos though). Using a Related Model Field To Sort Paginated Results <th><?php echo $paginator->sort('title'); ?></th> <th><?php echo...

Changing CakePHP's Model useTable on the Fly

Kevin Wentworth — Tue, 02 Nov 2010 17:12:00 +0100

I finally found an answer to/solution to something I've never been able to get around in CakePHP before: dynamically changing/setting the useTable value in a model. You can't just say $this->CakePHPModel->useTable = 'cakephp_table_name'; Instead you have to use the following function: Setting CakePHP Model useTable Dynamically $this->CakePHPModelName->setSource('table_name'); Thanks to Give Me Cake for sharing. This will work from the controller or the model. I'm using it to build an...

The Funniest Error Message Ever - Thank You Eclipse

Kevin Wentworth — Mon, 18 Oct 2010 18:34:00 +0100

In a depature from my [normally] on-topic (i.e. dry) posts I had to post this error message up here. It made me laugh! I was working on the fattest CakePHP controller known to man (over 4,000 lines, I know... not skinny) when Eclipse ran into issues. Eclipse gave a very descriptive error message, stating that it couldn't, well see for yourself: Error Processing Dirty Regions? Does that mean Eclipse only got to first base?

Upgrading CakePHP Application to 1.3 (from 1.2)

Kevin Wentworth — Mon, 27 Sep 2010 21:33:00 +0100

I've been waiting to publish a completed article until after I was done with my upgrade to CakePHP 1.3. Well, it's taking a while. I'm not blaming the CakePHP upgrade from 1.2 to 1.3 for taking so long. I'm actually doing several large-scale changes to my code base, my server and my repository structure. Until that time, I'm going to publish some notes I've been making for this article. CakePHP $form->create() ID Renames Huge Gotcha! We depend on the ID of the form to perform CSS...

Common SSH Commands (An Idiot's Guide)

Kevin Wentworth — Sat, 25 Sep 2010 09:25:00 +0100

Well, I never thought I would be saying this, but I'm starting to love using SSH to manage certain elements of my server. Now that I'm using ssh bash to make some updates to my server, I find myself constantly hunting for the simple commands. I'm going to put all the commands I need below, because I'm the idiot and it's my guide. Changing Directories / Navigating cd /dir/to/go/to/ cd ..

Using KDiff3 as Git GUI Merge Tool on Windows XP and Windows 7

Kevin Wentworth — Thu, 23 Sep 2010 13:39:00 +0100

I've been looking for the silver bullet solution to using KDiff3 as my git mergetool on Windows (using Git GUI). I've finally got a solution that works in every Windows environment I've tried: Add the KDiff3 directory to your Windows System Path (e.g. C:\Program Files\KDiff3\) Add kdiff3 as your Git mergetool (From Git Bash, run git config --global merge.tool kdiff3) Add kdiff3 complete path to Git Config (From Git Bash, run git config --global meregtool.kdiff3.path "C:/Program...

Getting All ACL Permissions in One Lookup (CakePHP 1.3)

Kevin Wentworth — Sun, 19 Sep 2010 11:36:00 +0100

The biggest hurdle I've had to overcome migrating my CakePHP application from 1.2 to the much improved 1.3 branch involves Plugins and the ACL component. A while back I noticed that my backend was kind of sluggish due to all of the ACL lookups (that happen with each request) so I optimized my ACL database tables . At that same time, I also discovered an incredible mysql query that would lookup all of the ACL permissions for a particular ARO. This setup worked great... until I started...

CakePHP 1.3 Improvements Over CakePHP 1.2

Kevin Wentworth — Thu, 09 Sep 2010 14:01:00 +0100

I've been working on upgrading my CakePHP application to cake version 1.3. It's a lot of work. I find myself constantly consulting the CakePHP manual/book for answers. There are many places to look for all of the improvements that were rolled into CakePHP 1.3 (at least coming from the 1.2 version). For my own reference, I'm creating a list of all of the manual pages that reference improvements, new features and/or different ways of doing things in CakePHP 1.3. CakePHP 1.3 Improvements...

CURL on Windows Doesn't Work in PHP 5.2.14 ISAPI

Kevin Wentworth — Tue, 07 Sep 2010 20:17:00 +0100

Just a quick post to let everyone know what I just found out- the version of CURL (php_curl.dll) that ships with PHP 5.2.14 for Windows ISAPI doesn't work! That's right- it doesn't work. I tried the MSI PHP installer package, manual installs, moving dll files into Windows and System32 directories all to no avail. The culprit: a bad version of php_curl.dll (at least that's my best guess). The other culprit: using ISAPI, but I don't have time to figure out FastCGI at this point. Here are...

Global Mysql Find and Replace with CakePHP

Kevin Wentworth — Tue, 31 Aug 2010 09:03:00 +0100

I'm moving my Content Management System over to CakePHP 1.3. I'll post an article about my experiences later. Today I will focus on one and only one issue with the migration from Cake 1.2 to 1.3: the change of webroot/theme/ to webroot/theme/ to serve static content. At first I was a little disapointed/scared at the prospects of making this change, but have since come to see the absolute brilliance in this approach. Files, easy. Content (Mysql data), hard? Moving all of my...

Difference Between Truncate and Empty (Delete From) in Mysql

Kevin Wentworth — Wed, 23 Jun 2010 14:30:00 +0100

I use Navicat for administering all of my MySQL databases. It has a command that I always use- empty table. I noticed today that all along there has been a command right below it for truncate table. Hmmm. I figured this would result in the same outcome and wondered what the difference is between emptying a mysql table and truncating the same table. Use TRUNCATE TABLE to Start Fresh After doing some research I found out that when you truncate a MySQL table, you are actually dropping...

Best Approach to Dynamic Javascript in CakePHP Views

Kevin Wentworth — Sat, 29 May 2010 12:36:00 +0100

I always knew in the back of my mind that there was a better way of creating dynamic javascript than the method I was using. CakePHP has a great function as part of the $View controller: $View->addScript($jscript, false) will add a script block to your template header. This is the command I use to send javascript created in a Cake view up to the header, which is where most javascript should live. The best approach to adding dynamic javascript to your CakePHP views is to implement PHP's...

Speeding Up Cakephp's ACL Component

Kevin Wentworth — Fri, 28 May 2010 12:12:00 +0100

I came across a posting today that changed the performance of my application tremendously and reinforced a concept I had forgotten about- mysql indices. I didn't realize my app was running slow until I implemented the mysql indexes below- no formal benchmark testing, but I would say speed improved by about 300%. The improvement was most noticeble when you are building your ACL using the CakePHP suggested method . MySQL Query to Create CakePHP ACL Indexes This code was originally found at ...

Best Free Mysql Zip code Database

Kevin Wentworth — Tue, 20 Apr 2010 16:42:00 +0100

I'm sure every developer reaches a point when they will need to use a mysql database of zip codes in the United States. Say you want to make a store locator and show how many miles a customer is from your store, or if you have some custom php logic that uses zip codes, you will inevitably need a mysql database of zipcodes. The Best Free Mysql Zip Code Database So here it is- my vote for the best database of zipcodes available in native mysql format on the Internet. From my limited...

Controlling CakePHP Error Handling When Debug = 0

Kevin Wentworth — Mon, 19 Apr 2010 16:27:00 +0100

I finally had a client request a piece of functionality that required me to program CakePHP so I could better control the default error handling when the site is in production mode (i.e. debug is set to 0). By default, CakePHP will throw a 404 page not found header whenever ANY errors occur on a production site with debug equal to zero. This works great, most of the time. But what about when you are having database connectivity issues? Say when there are too many mysql connections to...

Cache Results from Query in CakePHP

Kevin Wentworth — Wed, 24 Mar 2010 11:18:00 +0100

I have a HUGE query that I wanted to cache. I love CakePHP's caching functionality out of the box, but one thing is missing- you can't cache the results of a query. Let me clarify. You can cache the reults of a query, but only for that instance of a page load. Using $this->cacheQueries only caches the query to memory, which only lasts for the duration of the page load. If you want to cache query results to the file system, listen to Miles . Cache Query Results in CakePHP You'll...

Setting Envelope-From in CakePHP's Email Component

Kevin Wentworth — Mon, 22 Mar 2010 17:56:00 +0100

I've setup a form that allows customers to sign up for an email newsletter and receive a coupon. I wanted to be able to track the bounced messages in case a legitimate customer's coupon was bounced for whatever reason. As I've learned, setting up the "return-path" for an email message isn't as simple as setting $this->Email->return = 'email@domain.com'; You have to use an as yet undocumented feature... $this->Email->additionalParams; Making PHP mail() include your return-path email address...

2 Neat Little PHP Tricks

Kevin Wentworth — Tue, 16 Mar 2010 16:15:00 +0100

In writing a function to validate bank routing numbers , I came across two simple techniques, that I know I will need to use again: PHP Trick 1: Remove All Characters Except Numbers from a String A simple little regex does the trick: $routingNumber = preg_replace('[\D]', '', $routingNumber); PHP Trick 2: Loop Through a String Character by Character Setting two variables in a for loop does the trick (that could be trick number 3...): for ($i = 0, $j = strlen($routingNumber); $i < $j; $i++ )...

PHP Function to Validate Bank Routing Numbers

Kevin Wentworth — Tue, 16 Mar 2010 16:10:00 +0100

I needed to validate that a Bank Routing Number was valid, much like the algorithms out there to check if a Credit Card number is valid. I did a little searching and didn't find a PHP function that would do the trick. I decided to write my own, based on this javascript function , and publish it for anyone who wants to use it: Function to Validate Bank Routing Numbers: function checkRoutingNumber($routingNumber = 0) { $routingNumber = preg_replace('[\D]', '', $routingNumber); //only...

Use a Plugin Element Outside of the Plugin in CakePHP

Kevin Wentworth — Sat, 13 Mar 2010 13:03:00 +0100

Quick note- I had an element .ctp file that was part of a plugin. I wanted to render that element across my entire Site Avenger site, including non-plugin layouts and themes. I found out that you can send $this->element() (formerly $this->renderElement()) a 'plugin' parameter to accomplish this... otherise CakePHP will only look in the app-wide elements or themed elements folder. Render Plugin Element in Application echo $this->element('mini_cart', array('plugin'=>'avorders')); Cheers,...

Create a Checklist Group or Related Checkboxes in CakePHP

Kevin Wentworth — Fri, 05 Mar 2010 12:38:00 +0100

This is an interesting one. I needed to create a group of checkboxes. In my mind, it's just like a radio button group, except with checkboxes. The only difference should be that with radio buttons you can only select one, while with a checkbox group you should be able to select as many as you want. To achieve a checklist group in CakePHP is a little convoluted. First Step, Create an Input of type=>'select' That's right, if you want to make a group of checkboxes that are related in...

Export to PDF from Microsoft Publisher

Kevin Wentworth — Fri, 05 Mar 2010 10:54:00 +0100

I have a client that sends me newsletters in Microsoft Publisher format. I wanted to output the newsletter as a PDF, but wanted to keep the text for SEO and so users can copy and paste the text if needed. Microsoft Publisher doesn't have an export to PDF function, so usually I would just do a File > Print and select Adobe PDF as the printer. However, this would just be an "image" of the document, not the actual document with selectable text. This is how you can get a PDF with rendered...

Which Submit Button was Clicked in CakePHP? Use Name.

Kevin Wentworth — Thu, 04 Mar 2010 12:01:00 +0100

If you want to have multiple submit buttons that make a form do different things there's a simple way to do this. The name of the submit button that was clicked by the user will be sent (via POST) with all the other POSTed data. This is very handy if you want to have a cancel button and continue button. In CakePHP the name of the button won't be in $this->data, but it's easy enough to get... Give the Submit Button a Name echo $form->submit('Checkout Now',...

PHP Break Out of All Foreach or While Loops

Kevin Wentworth — Thu, 25 Feb 2010 14:44:00 +0100

Let's have some fun with PHP's break command... I didn't think it was possible. I just learned (I've been programming PHP for like 7 years) that you can instruct break how many levels of nesting to break out of! I'm not surprised that break in PHP allows you to specify the number of loops (or switch statements) to break out of, but I am surprised it took me this long to use it! Control How Many Loops PHP's Break Command Breaks Out Of It's easy to control, just add a number after the break...

Changing the Order Sequence of CakePHP Behaviors

Kevin Wentworth — Thu, 25 Feb 2010 07:20:00 +0100

For reasons too long to explain in this post, I have two behaviors that are run on the same pieces of data (a translate behavior and a settings import/export behavior). One behavior is attached to the model using var $actsAs, while the other behavior is attached dynamically, during runtime using $this->attachBehavior();. I needed the "hardcoded" behavior to run after the dynamically attached behavior. Here's what I did: Changing the Order of CakePHP Behaviors via $actsAs First, the...

Getting a List of Database Tables in CakePHP

Kevin Wentworth — Tue, 23 Feb 2010 12:22:00 +0100

I ran into an interesting problem today. What I wanted to do was know if a table didn't exist in my CakePHP application. What happens- a cakeError is thrown everytime a database table doesn't exist. This is really annoying...I think it would be beneficial to be able to tell Controller::loadModel() to return false instead of an error message. That's not the case. Here's how I got around it (with thanks to Miles Johnson ): Use Cake's Database Connection Manager to Return a List of...

Best CSS Method for Using Image as Submit Button

Kevin Wentworth — Wed, 03 Feb 2010 12:17:00 +0100

I came across an interesting issue with web forms and CSS. Surprisingly, the end result is much better than I expected. I knew that using an image instead of a traditional form submit button (<input type="submit">; instead of <input type="image"> or <input type="button">) would be a little challenging. I like a challenge, plus I wanted to use the submit button because it's the standard approach to forms and I remember reading somewhere that input's of type image or button do not submit...

Weird Git Error After Upgrade: Repository not found. Make sure you include the .git

CSS Min-Height Hack in Internet Explorer

Kevin Wentworth — Tue, 15 Dec 2009 10:18:00 +0100

Another day of web developing with CSS and another day of needing a hack for IE6 and IE7.

I've been working on setting up a multi-lingual web site for one of my clients. I was excited at the opportunity to finally use CakePHP's built-in internationalization and locale functions.

Jquery Accordion Menu - Expanding UL Menu

Kevin Wentworth — Tue, 17 Nov 2009 13:25:00 +0100

I looked around and found some interesting examples and existing plugins for creating an accordion menu in Jquery. What I was looking for was a nested unordered list (UL) that would collapse and expand based on which menu item was clicked. If there wasn't a child UL, then the menu link should be clickable, instead of an accordion. Sounds simple right? Semantic HTML Markup I wanted to keep my HTML clean, and for me that means using semantically correct UL/LI for presenting the...

Jquery Direct Descendant Selector (using the >)

Kevin Wentworth — Tue, 17 Nov 2009 13:08:00 +0100

I'd been struggling with a very simple accordion menu script . The problem was that I couldn't stop all of the links from returning false, when I only wanted to top link to return false. Let me show you my code: $('div#sideNav li:has(ul) a').click(function() { return false; }); What was going on (and correctly I might add) was all links contained in an li with a ul would return false, and wouldn't follow the link. I wrote this convoluted function to parse out the href and change the...

What is the Difference Between Oblique and Italic in CSS?

Kevin Wentworth — Thu, 12 Nov 2009 09:34:00 +0100

This answer was located at WebMasterWorld.com on 11/12/09. Answers written by johnl . I was reading up on the CSS font-style property, making sure the default value was normal. In case you are wondering, the default font-style value is normal. What struck me was a new value I've never used before: oblique.

CSS Small-Caps Working in IE Not in Firefox

Another IE/FF Inconsistancy? I thought I had ran into an interesting (and new) CSS bug. I was using Trebuchet MS as my font for my H2s. It was rendering perfect in Internet Explorer but not in Firefox. In Firefox, all caps. In IE, small-caps. What gives? C Stands for Cascading... It turns out that I hadn't specifically told the H2 to display text as normal. It was inheriting a style="text-transform: uppercase" from another CSS style definition.

This answer was located at CodingForums.com on 9/11/09. Answers written by PHP6 and Fou-Lu . I had been hunting for an answer to the elusive question of how do I reset array keys in PHP. I finally found the perfect (and thorough) answer here. There are 3 ways to reset array keys in PHP. All of these solutions work with numerically indexed arrays only. To recap: PHP Function: array_values() $reset_array_keys = array_values($numerically_indexed_array); PHP Function: array_merge()...

Date Input Using Cakephp Form Helper

Kevin Wentworth — Wed, 09 Sep 2009 15:29:00 +0100

I always forget what exactly needs to happen in order for CakePHP's form helper to work with date input fields. I'm sick of tearing through old source code and looking at the official CakePHP docementation site . Here's how to get it to work... Date Inputs Using the Form Helper: $current_year = date('Y'); $max_year = $current_year + 2; echo $form->input('dateSelectBoxes', array('type'=>'date', 'selected'=>$unix_timestamp, 'empty'=>true, 'minYear'=>2009, 'maxYear'=>$max_year)); It's...

Invalid Date Value Error in MySQL

Kevin Wentworth — Wed, 09 Sep 2009 14:26:00 +0100

I ran into an interesting issue with valid dates and MySQL on Windows. I wrote a CakePHP import function that basically moves MySQL data from one DB to the other. I never thought that I would see an error related to an invalid date, but I did. What determines if a date value is invalid (read: warning) or unacceptable (read: error)? It turns out to be based on the sql_mode you have specified for your MySQL server. I found this extremely thorough description of the different MySQL sql_mode...

Cakephp's Flay Class is Amazing - Examples Included

Kevin Wentworth — Tue, 08 Sep 2009 21:31:00 +0100

If you haven't checked out CakePHP's Flay class, check it out . It's one of the best utility classes for text output in CakePHP. I just noticed that my blog was using the same META description for all of my blog entries- not good for SEO. Instead, I want to pull a fragment of the article copy and use that as my META description. I currently use this convoluted way to get my summaries from the article copy, so I decided to try using the Flay class. I've used it before but I'm glad I...

Manually Installing MySQL on Windows 2003 Server

Kevin Wentworth — Wed, 02 Sep 2009 12:02:00 +0100

I have been trying to install MySQL on a web server running Windows 2003 for quite a while now. I was finally successful! Here's how I did it... Does your server have a hard-coded IP address? If so, you need to make localhost refer to the manually assigned IP address in your hosts file. This file is located in C:\Windows\System32\drivers\etc. Default hosts file will say: 127.0.0.1 localhost Modify your hosts file to reflect the binded IP address (be sure to save your changes!): 10.1.1.x...

Using Exif in PHP on Windows

Kevin Wentworth — Fri, 28 Aug 2009 09:40:00 +0100

I'm trying to use the exif functions in PHP on my Windows XP computer. I want to read the meta data that is recorded by my digital camera (exif - exchangeable image file format ). I like the idea of storing that exif data in the database, so it's searchable. I wasn't having any luck with exif_read_data(), but finally found this posting . You need to adjust your php.ini file. Move extension=php_exif.dll below extension=php_mbstring.dll (which needs to be enabled too). Your php.ini...

Making Valid Email (mailto) links in CakePHP

Kevin Wentworth — Tue, 25 Aug 2009 16:59:00 +0100

It's easy to make an email address using the HTML's helper link() function. All you need to do is have an email address appended with the string 'mailto:' (just like in regular ol' HTML). Here's my quick and dirty function to attach it if it doesn't exist: if(stristr($image['link'], '@') and stristr($image['link'], 'mailto') === false) { $address = 'mailto:'. $image['link']; } else { $address = $image['link']; } echo '<p>'. $html->link($image['link'], $address) .

Changing Filetypes Shown in SWF Upload File Browser

Kevin Wentworth — Tue, 25 Aug 2009 16:17:00 +0100

It's easy to change which file types are allowed to show up (and are displayed) when you browse for files to upload through SWF Upload. SWF Upload makes it easy to upload multiple files in PHP. I just had to hunt through some source files until I found this in my SWF Upload config. (goes in the new SWFUpload() function) <script type="text/javascript"> var swfu; window.onload = function () { swfu = new SWFUpload({// File Upload Settings file_size_limit : "8 MB", // 2MB file_types : "*.jpg;...

Network Solutions' Flawed .htaccess and Mod_Rewrite Rules Implementation

Kevin Wentworth — Thu, 06 Aug 2009 14:38:00 +0100

I can't believe it! I spent hours trying to get the mod_rewrite rules working in .htaccess on Network Solutions' servers. Everything I tried didn't work. Using the default .htaccess (from Cake distribution) failed. I've used the distribution on several servers and never had any issue with the rewrite rules. However, Network Solutions's mod_rewrite works differently than [all] other servers. The target and destination file have to exist Wait, the target file has to exist? That's right. ...

Cheatsheet for Creating .MOV Files from .VOB files (DVDs)

Kevin Wentworth — Thu, 30 Jul 2009 11:38:00 +0100

Every now and again I need to take a video from a promotional DVD and put it on a client's web site. I use a handy utility that will convert almost any video file into a flash video (.swf/.flv). The hard part usually comes from having to rip the video from the DVD. I use MediaCoder . It's Open Source, easy to use, and extremely powerful. The reason for my post, is to remember some settings. These settings are the ones that worked for me. I don't recommend them, but they...

TinyMCE Doesn't Work in IE8

Kevin Wentworth — Fri, 24 Jul 2009 11:54:00 +0100

I was training a client how to update their web site using Site Avenger when the strangest thing happened- no copy was showing in TinyMCE. No matter what I pasted the tiny editor would remain a nice, plain white. I didn't think to try typing directly into TinyMCE. No matter, a click on the HTML button to view the source revealed the content was in fact there, just not being shown within the TinyMCE editor. Tell IE8 to Use Compatibility Mode I found a link to a neat snippet of code...

Phantom Whitespace Below Img in Firefox

Kevin Wentworth — Wed, 22 Jul 2009 10:24:00 +0100

I've come across this thing a few times before- there's a strange space below images in Firefox, but not in IE. I finally found a nice explanation as to why it happens, which I wanted to post here. Images are displayed inline by default. When you are using an image as a block (like when you want an image to take up the entire top half of a page) you'll get some mysterious white space below the image, but only in Firefox. For once, IE actually seems to render the CSS appropriately. The...

Faking min-width CSS style in IE6 and IE7

Kevin Wentworth — Thu, 16 Jul 2009 13:50:00 +0100

It's a hack... but it's needed to make a truly cross-browser fluid layout. It's simple, if you want to implement min-width in IE6 and IE7, use the following CSS code: (I didn't create this originally, sorry, lost the source) /********************* ** IE 6.0 min-width hack ********************/ * html div#contentWrap { width:expression(((document.compatMode && document.compatMode=='CSS1Compat') ? document.documentElement.clientWidth : document.body.clientWidth) < 1000 ? "840px" : "85%"); }...

Avoiding Flash (.flv) 404 Errors on IIS 6 (Windows 2003)

Kevin Wentworth — Wed, 15 Jul 2009 11:11:00 +0100

An interesting thing happens on Windows 2003 Server (IIS 6) when you try and play a .flv file through an embedded shockwave player...nothing. Well, actually you get a 404 error. Fixing the .flv 404 error is simple All you need to do is tell the IIS server that the MIME type for .flv exists. Then, the web server can send the appropriate MIME-TYPE header when needed. Adding the .FLV MIME type to Windowss 2003 / IIS 6 You can modify the MIME type on the entire server by editing the...

Using Between with Date Ranges in Proper DB Date Format

Kevin Wentworth — Thu, 09 Jul 2009 11:56:00 +0100

I need my CakePHP apps to run on both LAMP and Windows IIS using MSSQL Server. Usually this isn't a problem because CakePHP does such a good job of database abstraction and database independence. However, I came across a scenario the other day where I needed to select a date range using the BETWEEN SQL command. Using CakePHP's BETWEEN function for date ranges It's easy, if you only want to use MySQL. Just do the following (note that the "lesser" or older date comes first):...

Adding Anchors to Your CakePHP Generated Urls (#link)

Kevin Wentworth — Thu, 02 Jul 2009 09:02:00 +0100

This may seem simple and trivial, but it took me a little while to figure out. If it saves someone a little trial-and-error then great (I know I won't forget how to do it). I needed to create a redirect in CakePHP that redirected to an inline, on-page anchor- <a name="destination">Scroll to Here</a>. Typing the link directly into the address bar of the browser, it would need to look like this: http://www.mainelydesign.com/blog/view/1219/#destination. The #destination is what I needed to...

Using CakePHP's Set Class to Make Select List Options

Kevin Wentworth — Fri, 19 Jun 2009 11:22:00 +0100

If you haven't become familar with any of the functionality of the CakePHP's Set class, I highly recommend you take a peak . I don't know too much about it and really only learn about it as I go. Well, I finally found out how to do something that used to take several lines of code: creating options for a select list that includes the Model.id as the key, but has a concatenated string for the value, like 'Model.name - created by Model.userName'. Using the Set class this is easy. With...

Changing the CakePHP Model Schema on the Fly

Kevin Wentworth — Thu, 11 Jun 2009 10:28:00 +0100

I have an interesting way of dynamically changing a model's validation on the fly. I have a standard approach that involves contact forms, contest entries, etc. using a database to store which fields should be on a form. I tweaked this over time, and recently needed to change the schema from text, which all answers have been up to this point (and IS the DB field type), to a type of date. I kept getting the error 'preg_replace expects parameter 2 to be a string, array given'. Once I got...

Displaying phpinfo() without CSS styles

Kevin Wentworth — Tue, 09 Jun 2009 10:18:00 +0100

I wanted logged in users to be able to see the output from phpinfo(); within Site Avenger. The problem with using phpinfo() is that it outputs a full HTML page, CSS styles and all. In the past this has been fine, but now I wanted to show the phpinfo() within the Site Avenger layout and CSS styles. I came across a simple, yet highly effective solution... Using Output Buffering to Capture PHPINFO() The solution is as simple as turning on output buffering, capturing the echo'ed value of...

Getting the File Path to the Vendor Folder

Kevin Wentworth — Mon, 08 Jun 2009 16:47:00 +0100

I'm trying to use a library within my CakePHP application that needs a variable defined that contains the complete file path to the vendors folder. This can be solved one of two ways- modify the library (which I don't want to do) or use the Configure::corePaths() function in CakePHP. Best Option - using Configure::corePaths() This is a great function I had not used until today. If you call it with no parameters, you'll get all of the file paths that Cake will look in when "building" your...

Fixing the Default HP OfficeJet Scanner Settings (which suck)

Kevin Wentworth — Thu, 28 May 2009 23:11:00 +0100

The default settings for my OfficeJet L7500 All-In-One Scanner suck! I thought the scanner was junk. Every photo I scanned, espcially glossy finished photos, were coming out looking like they were from a 1960s era camera: over-exposed and super high contrast. Not good! I thought I had good Photoshop skills, but even they were no match for the over-exposed mess that HP was sending into Photoshop. How did I improve the quality? Easy (usabilty rant- they should be the default settings, or...

Distinct vs. Group By in MySQL (and CakePHP)

Kevin Wentworth — Thu, 21 May 2009 11:27:00 +0100

An interesting problem- I am returning a list of files that have already been uploaded, so the user can link to an existing file. This creates a new record (duplicate record). The next time the user goes to select a file, there will now be two entries for the same file. DISTINCT to the rescue, or so I thought. DISTINCT applies to the whole select statement This is confusing in its own right. The CakePHP book misleadingly demonstrates that you can setup the fields parameter like so:...

Best Eclipse Feature: Link With Editor

Kevin Wentworth — Thu, 21 May 2009 09:43:00 +0100

I use Eclipse for all of my CakePHP development work. I love that you can get code completion, class inheritance, and more by following these steps . I also loved that I could have 20 something files opened, and when I changed the active document in the editor, my PHP Explorer hierarchy would change in response. So, I upgraded my Eclipse to Ganymede, so I could download the latest PDT and install the Git plugin (which I haven't even tried yet). Long story short, my PHP Explorer...

Dealing with MySQL Old-Style Passwords

Kevin Wentworth — Wed, 20 May 2009 16:37:00 +0100

I ran into a problem I've seen before- Client does not support authentication protocol requested by server; consider upgrading MySQL client. Last time I came across this MySQL error, it was a simple query to fix the issue (from dev.mysql.com ): UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd') WHERE Host = 'some_host' AND User = 'some_user'; FLUSH PRIVILEGES; That didn't work... instead IT CRASHED THE SERVER ! I was in a position that I couldn't upgrade the version of PHP...

Changing Display Options in Model::find('list')

Kevin Wentworth — Tue, 19 May 2009 10:49:00 +0100

I wanted to change the displayed field that Cake automatically returns with a Model::find('list'). If you have a database column named title or name (I'm not sure of the full list), CakePHP will automatically return an array index by Model.id => Model.name. This usually works, but today I'm working with a database table that doesn't use that field- it's a table of uploaded files and uses the columns named 'src' or 'alt' to display information to the user. I forgot how to do this, so I'm...

Getting the CakePHP Version in Your Code

Kevin Wentworth — Thu, 14 May 2009 10:57:00 +0100

I was sick and tired of having to FTP into my accounts and view the VERSION.txt file that comes with the Cake core to figure out what version of Cake I was running. I did a quick search but wasn't finding anything. I was about to dig in and hack something together, but tried the CakePHP API as a last resort. Bingo! To find out what CakePHP version you are running on, use the following command: Configure::version(); A string of the version will be returned. Simple, huh? Dare I say, easy...

Naming a Text File .htaccess on Windows

Kevin Wentworth — Wed, 13 May 2009 12:15:00 +0100

A big pain- you can't just name a file .htaccess through Windows Explorer. It complains that you need to supply a name! No problem. Here's how you can name a file .htaccess (only tested on Notepad, though hopefully it will work on more): Load up your file in Notepad or create a new file in Notepad Add your .htaccess declarations File > Save As In the filename text box put ".htaccess" - with the double quotes (".htaccess" exactly) In the filetype select box choose 'All Files' Save it! I...

Making Apache Parse .html files as .php Files

Kevin Wentworth — Wed, 13 May 2009 12:09:00 +0100

When re-designing a site, or somehow being locked into a given web site structure that uses .html (or .htm) file extensions, it's a good idea to keep the file names the same (especially if the site has been around a while and has good search engine visibility). Think you can't use PHP on .html or .htm web pages? Think again. With apache it's as easy as modifying the .htaccess file. On a server with PHP 5, add this line to your .htaccess file: AddHandler application/x-httpd-php5 .html .htm...

Keep Old Settings When Upgrading Eclipse

Kevin Wentworth — Tue, 12 May 2009 13:02:00 +0100

I decided to upgrade my version of Eclipse to 3.4 (Ganymede) mainly so I could use the Git plugin . I wanted to migrate my settings from one install to the other. I know I had done this before, when I upgraded from 3.2 to 3.3, but forgot how. So I don't have to scratch my head so much next time, here is how you can move your settings after you upgrade your version of Eclipse. I'm using Windows XP. Here's what I did: Go into your old version of Eclipse and do a File > Export Choose...

Avoiding New Line Errors using Git on Windows

Kevin Wentworth — Tue, 12 May 2009 12:27:00 +0100

I'm finally working on moving my code over to a version control system. I've tried several times over the past few years to start using Subversion, but I never quite got into it. After hearing so much about Git , I decided I needed to start using it. Luckily, most people tell you to forget everything about Subversion when using Git- no problem there! I ran into a huge issue. I created a new repository and wanted to add quite a large project (1,200+ files). At the end of adding all the...

Pagination with MSSQL in CakePHP

Kevin Wentworth — Thu, 07 May 2009 16:36:00 +0100

One thing, and there are a few, that I can't stand about having to use PHP and MSSQL Server together is the lack of support for pagination. With PHP and MySQL- no problem use limit. MSSQL- can't do it without all these ugly sub-queries. I have to give it to the CakePHP developers though, for the built-in support for pagination in MSSQL. Albeit it is flawed, it works. The problem with the CakePHP support for pagination in MSSQL is that on the last page of results you get a full result set...

A tale of caution: naming CakePHP "view" functions

Kevin Wentworth — Wed, 06 May 2009 17:13:00 +0100

Spoiler: functions that generate a view must be named using lower_case_with_underscores() I just ran into a very interesting problem. I was testing out some of my plugins to make sure they were still working with Cake version 1.2.2.8120. They worked fine except for one function. I had a form that updates a shopping cart, changing the quantities of products placed in the cart. When I hit the submit button to change the quantities, I was getting redirected to my site root. The first...

Getting Full Resolution Pictures out of MS Word (almost)

Kevin Wentworth — Wed, 29 Apr 2009 11:14:00 +0100

People use what they know. Most of the time I get photos embedded in an MS Word document for use on a web site. My workaround to date has been to enlarge the picture (in Word) until it is as big as it gets (keeping quality) or the size I need. I would then do a print screen and paste into Photoshop. I knew that there had to be a better way, but at least I was getting as much resolution as possible from the photo/picture. Well I came across an interesting scenario today- I couldn't...

Best Tiny Font for Web Graphics

Kevin Wentworth — Tue, 28 Apr 2009 17:03:00 +0100

I finally found the perfect font for making really small, yet readable text in web graphics. I've played around with plenty of fonts and usually arrive at a reasonable result. In the past I would use Eurostyle with enough spacing to make it legible. Now, I have a new go-to font for small typeface. Introducing Silkscreen . Usage Notes (for Photoshop CS2): It fails to render clean with pretty much any point size lower than 8 If the font looks blurry, turn off anti-aliasing You can have...

Preformatted Text in TinyMCE

Kevin Wentworth — Tue, 21 Apr 2009 10:26:00 +0100

Now that I've got my blog up and running, I've been playing around with syntax highlighting of source code. I really appreciate sites that serve up code samples in a nice format, so I've tried to comply with my own version of this best practice. Getting Geshi working, for syntax highlighting was one battle (I'll try and post what I came up with later). My real trouble came with using <pre></pre> tags for my code samples within TinyMCE . I absolutely love TinyMCE! I did a lot of...

$paginator->sort() error?

Kevin Wentworth — Fri, 17 Apr 2009 13:32:00 +0100

I thought there was an error in the paginator view helper. All of a sudden I could only sort a field ascending. I (again) did a little research and came across a great thread on the CakePHP Google Group ( here ). Basically, as of 1.2.8120, you need (or should) specify the ModelName in your sort() function. I had only been doing sort('id'), sort('name'). Now I am doing sort('ID', 'ModelName.id') and sort('Name', 'ModelName.name'). It's a little more work having to specify the label...

Transactional Support in CakePHP

Kevin Wentworth — Fri, 17 Apr 2009 11:50:00 +0100

I just found out that CakePHP has transactional support built-in. It should have been obvious, seeing how the saveAll() function has transaction support built-in too. My first attempt at using it didn't work. In my contoller/model I was doing the following: $this->Model->begin(); if(!$this->Model->save($this->data)) { $this->Model->rollback(); } else { $this->Model->commit(); } Based on the API and my limited knowledge of inheritance, I figured this would work. It didn't. I was a little...

saveAll() to save multiple records in 1 model

Kevin Wentworth — Fri, 17 Apr 2009 09:58:00 +0100

I ran into another issue on something I thought would be simple: saving multiple records with the saveAll() command. In case you don't know about it, saveAll() is one of the best functions in CakePHP. It automatically supports transactions, HABTM saves, and certainly saves a lot of typing for almost every type of save you want to do. There are a few gotchas. Here what I ran into: Inserting/creating new rows in the database, don't forget $this->ModelName->create() //no duh, right? Well,...

Checkbox - setting the default state

Kevin Wentworth — Fri, 17 Apr 2009 08:31:00 +0100

I ran across a rather simple problem (I thought) that took a little searching to figure out. All I had to do was create a checkbox form input that I wanted to have checked by default. I tried 'default'=>'checked', which didn't work. I also tried 'checked'=>true and 'checked'=>1, but that works every time, even if validation fails and the user had unchecked the checkbox, it will be checked again (Not good usability). The solution lies in a less-than-automagic approach. Too bad this...

Importing an Excel file into CakePHP

Kevin Wentworth — Thu, 16 Apr 2009 14:42:00 +0100

I needed to be able to upload an excel file, parse the file, and then add each row as a separate database entry. I had this working for a CSV file using the php built-in function fgetcsv() , but the client switched to using an excel file (instead of direct PHP access to the in-house database, we decided to have the client upload a CSV/Excel file). I did a little research and found the perfect solution- PHP-Excel Reader . I saved this to my CakePHP vendors directory and had to make one...
