CakePHP 3.0 - Regex Test

Question

I need to check the 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:

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

In addition, there is no mention of regular expressions in Cake 3.0 validation documentation , unlike Cake 2 documentation.

Was it changed or changed?

Answer 1

try it

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