Change the wordpress user display name

[PierreL]

Hello, I’m trying to change the wordpress user display name when a simple membership user is created.

I’m trying this following code :

function change_display_name_user_register ( $user_id ) {
    
    // get the user meta data
    $user_info_other = get_user_meta( $user_id );

    // pick our default display name
    $display_publicly_as = $user_info_other["first_name"][0] . " " . $user_info_other["last_name"][0];
    // update the display name

    wp_update_user( array ('ID' => $user_id, 'display_name' =>  $display_publicly_as));
}
add_action( 'user_register', 'change_display_name_user_register', 10, 1 ); 

this code seems to work but it does not change anything.

what’s wrong with this, is there an other “hook” to use to redefine wordpress display_name ?

Is someone has already dealt with this case ?

Thanks in advance for your help.
