在Cakephp中设置自定义验证规则时遇到问题

Question

I creating a custom validation rule in my cakephp model.

        'article' => array(
                'rule' => '/^[a-z0-9#.,&; ]{2,255}$/i',
                'required' => true,
                'allowEmpty' => false,
                'message' => 'Alphabets and numbers only(3,255).'
        ),

This works fine. But It stops working, throws a error in model, when I add forward slash [/] . I can't understand why forward causes a problem.

I appreciate any help.

Thanks.

As stated in your other question, read about preg_match() patterns in the php manual. This function is used internally in the framework.
