Form API Field Permission

Question

I am creating a custom form and storing data in custom table. I was wondering if there is any method to apply field level permission like

$form['value']['#permission'] = array('access this field');

I know I am having field permission module to apply permission on core fields but how I can achieve this?

Answer 1

As said by Adi, '#access' in your form will give access to a form field based on a user role.

Answer 2

I am already not try this but i think it will work

function mymodule_form_alter(&$form, &$form_state, $form_id) {

  global $user;
  if ($form_id == 'FORM_ID') {
  if (in_array('yourrole', $user->roles)) {
  $form['your_field']['#access'] = FALSE;
    }
  }
}
