Zend form validation

Question

I am using Zend Form to create dynamic form.

I have Zend Form validation too.

Trying to remove Validation dynamically, but not getting any success.

Can you plz help me to remove Zend Validation.

Bellow is my code for remove validation :

$toRemValArray = array();
$toRemValArray[0] = 'ele_4af42ceac7810';

if(isset($_POST['btnPost_x'])){                 
    if ($form->isValid($_POST)) {
        $allElements = $form->getElements();
        foreach($allElements as $val){
            if(in_array('ele_4af42ceac7810',$toRemValArray)){
                $value = $form->getElement($val->getName());
                $value->removeValidator('ele_4af42ceac7810');
            }
        }
    }
}

Let me know whether my code is having any issue

Answer 1

You should remove the validator BEFORE calling $form->isValid().

Terminology

Answer 2

The solution I came up with was overriding the isValid method on my form class and removing the validator on the password field if it was left blank:

public function isValid($data)
{
    if (empty($data['password'])) {
        $this->form
             ->getElement('password')
             ->clearValidators();

        $this->form
             ->getElement('password_confirm')
             ->clearValidators();
    }
    return $this->form->isValid($data);
}

The $this->form is referred to the form being extended by composition, the solution works when extending a Zend Form descendent class as well.

Just a side note, this solution won't work if the password field is required

Answer 3

Your code is removing a validator by name

$value->removeValidator('ele_4af42ceac7810');

This is typically something like NotEmpty or Regex as opposed to the element name.

Maybe you want

$value->clearValidators();

Also, +1 Ismael - you should remove it prior to calling $form->isValid()
