I found this code at StackOverflow.com (http://stackoverflow.com/questions/2041746/wordpress-get-user-id-by-login-name/9024155#9024155) which was really helpful in finding my own user number:
<?php
$user_id = get_current_user_id();
echo “ID User : “.$user_id ;
if ($user_id == 0) {
echo ‘You are currently not logged in.’;
} else {
echo ‘You are logged in as user ‘.$user_id;
}
?>
I included it in a template file and found my user ID number, which was 14 by the way, a bit unexpected (thought it was 1 or 2).
Would be helpful if the plugin reported “User not found” when you enter a user id number which isn’t found.
Thanks for a great plugin!
There’s also an easier way to find a users user ID number. In the WP-admin screen, click on “Users” and hover over the username of the user whose user ID you’re searching for. The URL will show you the ID:
/wp-admin/user-edit.php?user_id=17
Hope this helps!
