Force display name to nickname wp

Question

I wondered if anyone has a solution for the following scenario i would like to force when a user registers Display name publicly to Nickname by default instead of first name and last name which is what is set by default in WP.

Many thanks in advance JM

Answer 1

You can use the user_register hook, which is fired after the user is registered, to set the name to whatever you like:

function fix_user_display_name($user_id) {
    $user = get_user_by('id', $user_id);
    $display_name = $user->user_nicename;

    wp_update_user(array(
        'ID'           => $user_id,
        'display_name' => $display_name
    )) ;
}

add_action("user_register", "fix_user_display_name", 20);[1]

Hi Guys in response to further details on my answer, so basically i searched for plugin solutions in preference to adding code (i am not a developer) and found a plugin that does the job very well called change display name publicly as. Hope this feedback is relevant and helpful.
