    <p>I want to use the custom validation functions in the Uploader behaviour, width and height, to create a new custom validation function which tests if the image is square. So when I am using the behaviour in the model this is how I am using the File Validation functions. I have outlined what I want to do below in the my SquareValidation function as well.</p> <pre><code> public $actsAs = array( 'Uploader.FileValidation' =&gt; array( 'image' =&gt; array( 'extension' =&gt; array( 'value' =&gt; array('gif', 'jpg', 'jpeg', 'png'), 'error' =&gt; 'You can only upload images' ), 'mySquareValidation' ) ) public function mySquareValidation () { return width = height; // WHAT IS THE RIGHT SYNTAX TO ACCESS WIDTH AND HEIGHT BEHAVIOUR FUNCTIONS? } </code></pre> <p>But how do I access those core (to the behaviour) validation functions inside a custom validation function and use them to check if the submitted file is square (I want to allow any height/width combo). I know that to call a core validation function (to CakePHP) I would for example simply use:</p> <pre><code>Validation::rule($this-&gt;data['field']) </code></pre> <p>So how do I do the same for the core validation functions belonging to the behaviour? And when I have created the custom validation function, do I then execute the function in the behaviour array just like I would in the validation array (like in my example)?</p> <p>Reference: Uploader docs - <a href="http://milesj.me/code/cakephp/uploader#validating-against-a-model" rel="nofollow">http://milesj.me/code/cakephp/uploader#validating-against-a-model</a></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
