ZF2 : Priority for Validators in InputFilter

问题

I have a validator on a form entry like this :

    $this->add(array(
        'name' => 'email',
        'required' => true,
        'filter' => array(
            'name' => 'StripTags',
        ),
        'validators' => array(
            array(
                'name' => 'NotEmpty',
                'options' => array(
                    'messages' => array(
                        \Zend\Validator\NotEmpty::IS_EMPTY => 'Veuillez renseigner une adresse e-mail.',
                    ),
                ),
            ),                
            array(
                'name' => 'StringLength',
                'options' => array(
                    'encoding' => 'UTF-8',
                    'min' => 1,
                    'max' => 100,
                ),
            ),
            array(
                'name' => 'EmailAddress',
                'options' => array(
                ),
            ),
        ),
    ));

There's basicaly 3 validators on my input. The NotEmpty, the StringLength, and the EmailAdress.

Is there any way to set a kind of priority between them ? Right now, if I submit an empty form, I get messages relative to those 3 validators, ie. :

My input is empty.
My string length is too short (thanks...)
My input is not an email (thanks again...)

Is there anyway to tell my validator to stop at the first failure ? (or at least to only print the 1st message).

回答1:

Use the 'break_chain_on_failure' key in your validator spec with a value of true, ie

$this->add(array(
    'name' => 'email',
    'required' => true,
    'filter' => array(
        'name' => 'StripTags',
    ),
    'validators' => array(
        array(
            'name' => 'NotEmpty',
            'break_chain_on_failure' => true,
            'options' => array(
                'messages' => array(
                    \Zend\Validator\NotEmpty::IS_EMPTY => 'Veuillez renseigner une adresse e-mail.',
                ),
            ),
        ),                
        array(
            'name' => 'StringLength',
            'break_chain_on_failure' => true, 
            'options' => array(
                'encoding' => 'UTF-8',
                'min' => 1,
                'max' => 100,
            ),
        ),
        array(
            'name' => 'EmailAddress',
            'options' => array(
            ),
        ),
    ),
));
