WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

I'm trying to make a table of users by role type. What is the best-practices method of getting the user id? My goal is to print each users first & last names, username and email.

What I have now:

$get_admins = array(
    'blog_id' => $GLOBALS['blog_id'],
    'role' => 'administrator',

$blogusers = get_users($get_admins);
foreach ($blogusers as $user) { 
$userid = get_userdata($bloguser->user_id);
$user_info = get_userdata($userid);

    echo '<tr>';
        echo '<td>'. $user_info->user_firstname .'</td>';
        echo '<td>'. $user_info->last_name .'</td>';
        echo '<td>'. $user->user_login .'</td>';
        echo '<td>'. $user->user_email .'</td>';
    echo '</tr>';

note: In my example above getting the user id does not work.

Codex reference: get_users()

Your code doesn't work because you're using $bloguser instead of $user.

And there's no point in calling get_userdata() since get_users() already returns user objects:

foreach ($blogusers as $user) {
    echo '<tr>';
        echo '<td>'. $user->first_name .'</td>';
        echo '<td>'. $user->last_name .'</td>';
        echo '<td>'. $user->user_login .'</td>';
        echo '<td>'. $user->user_email .'</td>';
    echo '</tr>';

Dropping the redundant code works for stuff stored in the wp_users table. First/last name though is meta and stored in wp_usermeta. [I'm sure you already know this :)] So using $user->user_firstname isn't putting out anything. What am I not understanding? Thanks @Scribu – mattrepublic Aug 5 '11 at 0:00
get_users performs a join to the meta table, and the fields param defaults to all so that meta data should come back in the query(unless a given value isn't currently set for the given user(s)). Verify the users you're not seeing a first name for definately have one set. – t31os Aug 5 '11 at 0:10
That was the issue, I can't believe I overlooked that! Thanks @t31os! – mattrepublic Aug 5 '11 at 0:15
