Zend 2 Form Fieldset可选验证

Question

I'm using a lot of nested Fieldset and was wondering if is it possible to set a required=false to a specific fieldset in order to not throw an error if there is any in it (and keep my form validating) ?

For example this is my UserFieldset :

-> {User Fieldset}
-----> Name
-----> Email address
-----> [other user fields...]
-----> {Avatar Fieldset}
----------> File
----------> [other avatar fields...]
-----> {other fieldsets...}

In my situation I want sometimes to force my user to add an avatar and sometimes not..

When I want to force there is no problem, my input file in my Avatar fieldset throws an error and blocks the validation process.

But when I want my user to simply register and eventually set its avatar, how can I do it ?

Thank you for your help.

You can modify the elements that are validated using the setValidationGroup() method.

The documentation states

Zend\Form provides a proxy method to the underlying InputFilter‘s setValidationGroup() method, allowing us to perform [validation] on only a subset of form elements

This could be done within the controller or perhaps a new factory; for example:

// Module.php
public function getFormElementConfig()
{
  return array(
      'factories' => array(
          'MyModule\Form\AvatarRegistrationFieldset' => function($fem) {

             $fieldset = new Form\AvatarFieldset();

             // Include the name of the elements you WANT to be validated
             $fieldset->setValidationGroup('foo', 'file');

             return $fieldset;
          }
      ),
  );
}
