Get PHP File Uploads Working

The first trick to having any user contributed content these days is to get PHP File Uploads working (especially with big files).  Our configuration we use for our Wamp local development and on our Linux server is below.

When managing file uploads to a server, there seems to be a lot of confusion regarding optimized PHP settings and configuration. We have had some experience with this that we would like to share.

Speeding Up Windows 8 for Web Development (using WAMP)

Posted on 02/25/2013 at 01:33 pm | Viewed 48,704 times | 0 comments

Here is my list of optimizations and changes you can make (and I've had to make) in order to get WAMP (and CakePHP) to run faster on my Windows 8 computer.

Speed Up WAMP Web Development on Windows 8

The short list, in order of importance (stop once you are happy with your localhost web server response time and speed):

• Get the latest version of WAMP.
  Start by downloading the latest wamp.  I used the 64 bit version.  Download WAMP here.
  
  
• Edit your hosts file.
  Make sure it has the proper entries, and most importantly, remove the IPv6 localhost setting.  Your Windows 8 hosts file should look like this:
  
  127.0.0.1          localhost
  #    ::1             localhost
  
  
• Disable IP v6
  A great tutorial can be found here.  My advice is to disable IPv6 BOTH ways- via the network adapter and via the regedit hack.
  
  
• Edit Apahce httpd.conf. 
  These tweaks are supposed to speed up the lstat() system calls when reading files/scanning directories.  They are:
  
  EnableMMAP On
  EnableSendfile On
  
  
• Edit PHP.ini
  Increase the real path cache size.  This helps when you have lots of files involved.
  
  ; Determines the size of the realpath cache to be used by PHP. This value should
  ; be increased on systems where PHP opens many files to reflect the quantity of
  ; the file operations performed.
  ; http://php.net/realpath-cache-size
  realpath_cache_size = 24M
  
  
• CakePHP: make sure debug is off.

CakePHP Form Security Blackhole on Large Forms

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.

Forcing A Single Join in CakePHP Pagination

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.

Inserting NOW() into MySQL Using CakePHP

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.

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 would fail, but the CakePHP error messages were not being shown.

Getting All ACL Permissions in One Lookup (CakePHP 1.3)

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 upgrading to CakePHP 1.3.

Best Approach to Dynamic Javascript in CakePHP Views

Posted on 05/29/2010 at 12:36 pm | Viewed 23,253 times | 5 comments

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 output buffering, combined with $View->addScript().

Controlling CakePHP Error Handling When Debug = 0

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 that overloaded shared hosting box?  Modifed CakePHP error handling to the rescue.

Cache Results from Query in CakePHP

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.

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.

$paginator->sort() error?

Posted on 04/17/2009 at 01:32 pm | Viewed 11,009 times | 0 comments

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 (otherwise it defaults to ModelName.field, instead of just field).

Transactional Support in CakePHP

Posted on 04/17/2009 at 11:50 am | Viewed 14,731 times | 0 comments

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();
}

saveAll() to save multiple records in 1 model

Posted on 04/17/2009 at 09:58 am | Viewed 18,946 times | 0 comments

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.

Checkbox - setting the default state

Posted on 04/17/2009 at 08:31 am | Viewed 14,883 times | 0 comments

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).

Importing an Excel file into CakePHP

Posted on 04/16/2009 at 02:42 pm | Viewed 33,690 times | 0 comments

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).
