Sex & Zend: Zend framework form input fields validator

zend framework form add validator




http://framework.zend.com/manual/1.12/en/zend.form.elements.html

->addValidator('Regex', false, array('/^[a-z0-9]{6,}$/i'))

If failing a particular validation should prevent later validators from firing, pass booleanTRUE as the second parameter:

1. $element->addValidator('alnum', true);

If you are using a string name to add a validator, and the validator class accepts arguments to the constructor, you may pass these to the third parameter ofaddValidator() as an array:

1. $element->addValidator('StringLength', false, array(6, 20));

Arguments passed in this way should be in the order in which they are defined in the constructor. The above example will instantiate the Zend_Validate_StringLenth class with its $min and $max parameters:

1. $validator = new Zend_Validate_StringLength(6, 20);

Its addValidatorS (multiple validators):

$this->addElement('text', 'firstname', array(
                          'label'      => 'Your first name:',
                          'required'   => true,
              'validators' => array(
                  array('regex', false, array(
                  'pattern'   => '/[^<>]/i',
                  'messages'  =>  'Your first name cannot contain those characters : < >'))
              )
));
