CakePHP 3.0 - 正则表达式验证

Question

I need to validate an input based on a regular expression.

 //Validator
 $validator
            ->notEmpty('sl_no')
            ->add('reg_no', 'validFormat',[
                    'rule' => '/^([ABCD]{2,2}[0-9]{4,4})$/i',
                    'message' => 'Please enter a valid serial number.'
            ]);

But I get the following error:

Method /^([ABCD]{2,2}[0-9]{4,4})$/i does not exist.

Also, there is no mention of regular expressions in Cake 3.0 validation Documentation unlike Cake 2 Documentation .

Has this been moved or modified?

Answer 1

Try this

 $validator
        ->notEmpty('sl_no')
        ->add('reg_no', 'validFormat',[
                'rule' => array('custom', '/^([ABCD]{2,2}[0-9]{4,4})$/i'),
                'message' => 'Please enter a valid serial number.'
        ]);
