How to hide certain fields on the User Edit form?

Question

So I have three types of users - admin, LA admin and users. I am trying to set it up so that admins and LA admins cannot edit the username, password and timezone for users. I am talking about the default user edit form for admins and the form ID is "user-profile-form".

I have created a custom module but this doesn't seem to be working. Any idea what I might be doing wrong?

Even the var_dump does not seem to be outputting. I have cleared the cache and verified that the module is enabled.

function profile_change_form_alter(&$form, $form_state, $form_id) {
    if ($form_id === 'user-profile-form') {
    // Use var_dump  to dump the $form array to see the fields. 
        var_dump ($form);

        hide($form['account']['pass']);
        hide($form['account']['current_pass_required_values']);
        hide($form['account']['current_pass']);
    }
}

Answer 1

You need to replace form id user-profile-form with user_profile_form

Your code should look like the following:

function profile_change_form_alter(&$form, &$form_state, $form_id) {
    // changed form id
    if ($form_id === 'user_profile_form') {
        // Use var_dump  to dump the $form array to see the fields. 
        var_dump ($form);

        hide($form['account']['pass']);
        hide($form['account']['current_pass_required_values']);
        hide($form['account']['current_pass']);
    }
}

This code will work if you want to disable the field instead of hiding them.

function MODULENAME_form_alter(&$form, &$form_state, $form_id) {
  global $user;
  if ($form_id == 'user_profile_form') {
    if ($user->uid != 1) {
      $form['field_joining_date']["#disabled"] = TRUE;
    }
  }
}

Replace the 'field_joining_date' by your custom field name.
