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

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? Checking for empty variables in CakePHP 3 View
- // in the controller/cell/etc.
- $someVar = $this->find('threaded', ['order' => 'lft ASC'])->where($conditions);
- // in the view.ctp file
- if($someVar.isEmpty()) {
- return null;
- } else {
- // ... do your thing ...
- }
Now, that was pretty easy. If you want to find the count of records and you are at the query layer, you can use the $query->count() method, described here.
Cheers,
