Is it possible to add a field to a specific user role?

[Jonathan Lahijani]

I understand how to add a field to users (regardless of role), however I would like to add a field that only is assigned to a specific user role.  Is this possible?

Couldn't find any information about this in the forums or documentation, so I'm resorting here to the forums.  Sorry if this is a repeat question.

Hi jlahijani,

If you assign a field to a user template, then all users get that field.

Can you explain a bit more why you need this behaviour?

It would be easy to hide this particular field for all other roles with a hook.

In my situation, Users in Role A will require a set of fields that Users in Role B will not need and vice versa.

I would assign all the fields and just fill out the ones needed depending on the role.

Like I said, if you don't want the user to see the unecessary fields in the backend, you could hide them.

Maybe someone comes up with another solution, there are always multiple with Pw

Thanks Wanze.  I'll look into the hook method you mentioned.

You're welcome.

Here's a good overview how Hook works: http://processwire.com/api/hooks/

Also checkout the captain which shows you all the hooks available: http://somatonic.github.io/Captain-Hook/

And here an example, written in the browser and not tested:

// Inside your autoload module you have installed...

public function init() {
  $this->addHookAfter('ProcessPageEdit::buildForm', $this, 'hideFields');
}

public function hideFields(HookEvent $event) {
  
  // Do nothing if we don't edit a user
  if ($this->page->template != 'user') return;
  
  // Get the form instance returned from the hooked method
  $form = $event->return;
  
  // Define fields to hide per role
  $hideFields = array(
    'role1' => array('field1', 'field40'),
    'role2' => array('field5', 'field2'),
  );
  
  // Hide the fields
  foreach ($hideFields as $role => $fields) {
    if ($this->user->hasRole($role)) {
      foreach ($fields as $field) {
        $f = $form->get($field);
        $f->collapsed = Inputfield::collapsedHidden;
      }    
    }
  }

  $event->return = $form;

}
