Question

How can I check in my controller which one of the validation rules failed? I want to know if ‘rule2’ failed, based on the validation rule key.

public $validate = array(
    'email' => array(
        'rule1' => array(
            'rule' => array('email', true),
            'message' => 'Please enter a valid email address'
        ),
        'rule2' => array(
            'rule' => 'isUnique',
            'message' => 'Email address already registered'
        )
    ),
);

I know I can do debug($this->User->validationErrors) but all that shows is the message, and I don’t want to check the message because I might change that in the future.

Is there any way to see that 'email.rule2' failed, based on the validation rule key?

Answer 1

for me it never made sense that the default param for last is false

IMO the correct approach is:

public $validate = array(
    'email' => array(
        'rule1' => array(
            'rule' => array('email', true),
            'message' => 'Please enter a valid email address',
            'last' => true
        ),
        'rule2' => array(
            'rule' => 'isUnique',
            'message' => 'Email address already registered'
        )
    ),
);

ONLY check on unique if the email is valid in the first place.

and no, the message is the only thing returned. why is it important what failed?
