CakePHP

I ran into the following warning while using a validation rule in CakePHP: 

Warning (2): preg_match() [function.preg-match]: Delimiter must not be alphanumeric or backslash [CORE/cake/libs/model/model.php, line 2431] 

The problem was I spelled the validation rule incorrectly. I used 'nonempty' instead of 'notempty'. The correct usage is:

var $validate = array(
  'description' => array('notempty'),
);

If you experience this error, then make sure all built in validation rules are spelled correctly.

I discovered the CakePHP framework only several weeks ago, and I'm already creating useful web applications with little effort. After briefly looking at several PHP frameworks, I chose to start learning CakePHP because I could easily find documentation on getting started. Once I learned how to use the bake feature to automatically build a skeleton for my application, I was hooked.
