Drupal email field

Question

How can I lock the default e-mail field (make it read only), so that users will not be able to change their e-mail addresses after registering.

Thanks

Answer 1

You can achieve that by using hook_form_alter() in your template.php, there is an elaborate solution here: http://drupal.org/node/1241204#comment-7057244

*The following code was created by Isabug at the previous link:

/**
 * Implements hook_form_alter().
 */
function mytheme_form_user_profile_form_alter(&$form, &$form_state, $form_id) {
  global $user;
  $roles = $user->roles;
  if(in_array('administrator', $roles)) {
    return;
  }
  $form['account']['mail']['#disabled'] = TRUE;
}

Cheers,

You can disable email field using jquery,

Set the disabled attribute.

$("yourIdorClassforemailfield").attr('disabled','disabled');

To enable again

$("yourIdorClassforemailfield").removeAttr('disabled');
