How to use multiple validators in zend form ??

Use of multiple validation in zend form >>

First basic how to add validator to any filed..

$password = new Zend_Form_Element_Password('password');
$passsword->setLabel('Password :')
           ->setRequired(true)
           ->addValidator('NotEmpty')
           ->addValidator('Digits');

So, on this we use two validator one is 'NotEmpty' and second is 'Digits'.

Now problem comes when we submit we got both message together which not good. see in below images.

So, now solution is here..

just use custom modification you can write custom message using setMessage..

$notEmpty = new Zend_Validate_NotEmpty();
$notEmpty->setMessage('The field cannot be empty!');

$digits = new Zend_Validate_Digits();
$digits->setMessage('Please, enter only digits');

$password = new Zend_Form_Element_Password('password');
$passsword->setLabel('Password :')
          ->setRequired(true)
          ->addValidator($notEmpty, true)
          ->addValidator($digits, true)

use of regular expression validator.

->addValidator('regex', true,array('pattern'=>'/^[(0-9)]+$/',
        'messages'=>array('regexNotMatch'=>'Please enter only digit.'))
               )
