I want to display the uid (read-only) of the user on both the user/x and user/x/edit page.

By using the function below I managed to show the uid on the user/x/edit page.

function my_module_form_user_profile_form_alter(&$form, &$form_state, $form_id) {
    if (arg(0) == 'user') {
        $form['uid_read_only'] = array(
            '#markup' => 'User id : ' . '<b>' . arg(1) . '</b>',
            '#weight' => -500,
            '#disabled' => TRUE,
        );
    }
}

How do I show the uid on the user/x page (view state)?

  • Your code will display the uid of the currently logged in user. This is only the same as x if the user edits his own account. If I edit the account of a different user, my uid will still be displayed instead of the uid of the user whose account I edit. I don't think this is what you want. – Oswald Sep 19 '12 at 13:27
  • You're right, thanks for noticing. I think just grabbing the arg(1) is sufficient, agree? – undersound Sep 20 '12 at 16:01
  • Yes, arg(1) is sufficient in your case. The alternative would be to call menu_get_object(), passing 'user' as $type and 1 as $position. This gives you the user object associated with the URL. But I do not see the benefits of this method. – Oswald Sep 20 '12 at 17:49
  • ok, to close it off...is it correct when I'm saying that the check I'm performing if (arg(0) == 'user') is not really necessary because this function form_user_profile_form_alter will always and only be executed on a page with arg(0) as user? – undersound Sep 20 '12 at 18:59
  • Taking only the Drupal core into account, you are correct: the check for arg(0) == 'user' is not necessary. Contrib modules might see this differently. I usually make a clear distinction between form builder functions (that don't make any assumption about why they were called) and page callbacks (that accept arguments from the URL). E.g. in my opinion, it's a mistake that the form builder function user_login issues a drupal_goto. – Oswald Sep 20 '12 at 22:46

Implement hook_user_view() to show the uid on the user/x page.

Start by copying drupal theme user-profile.tpl.php into your theme, make sure to keep the name as user-profile.tpl.php.

open the file and edit it the way you want, I usually use this to get the uid

global $user
$uid = $user->uid;

then maybe you want to do something like:

print $user->uid;

Dont forget to clear your cache.
