Context

I've created a front-end "edit profile" template. When I input a value into the nickname text box only the nickname is updated. The default WordPress forum has a select menu that allows/requires the user to select their display_name (a text box for the nickname, a select menu for the display_name).

My form doesn't do this because I can't figure out a means of forcing the nickname to update the display_name additionally (i.e. I have a text box for the nickname but not a select menu for the display_name - I want to automate this).

display_name is stored in the 'users' table. nickname is stored in the 'users_meta' table.

Code for saving:

<?php
/* Get user info. */
global $current_user, $wp_roles;
get_currentuserinfo();

/* Load the registration file. */
require_once( ABSPATH . WPINC . '/registration.php' );

/* If profile was saved, update profile. */
if ( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) && $_POST['action'] == 'update-user' ) {

    /* Update user password. */
    if ( !empty($_POST['pass1'] ) && !empty( $_POST['pass2'] ) ) {
        if ( $_POST['pass1'] == $_POST['pass2'] )
            wp_update_user( array( 'ID' => $current_user->id, 'user_pass' => esc_attr( $_POST['pass1'] ) ) );
        else
            $error = __('The passwords you entered do not match.  Your password was not updated.', 'profile');
    }

    /* Update user information. */
    if ( !empty( $_POST['url'] ) )
        update_usermeta( $current_user->id, 'user_url', esc_url( $_POST['url'] ) );
    if ( !empty( $_POST['email'] ) )
        update_usermeta( $current_user->id, 'user_email', esc_attr( $_POST['email'] ) );
    if ( !empty( $_POST['first-name'] ) )
        update_usermeta( $current_user->id, 'first_name', esc_attr( $_POST['first-name'] ) );
    if ( !empty( $_POST['last-name'] ) )
        update_usermeta($current_user->id, 'last_name', esc_attr( $_POST['last-name'] ) );
    if ( !empty( $_POST['description'] ) )
        update_usermeta( $current_user->id, 'description', esc_attr( $_POST['description'] ) );




   if ( !empty( $_POST['display_name'] ) )
        update_usermeta($current_user->id, 'display_name', esc_attr( $_POST['display_name'] ) );
   if ( !empty( $_POST['memberlocation'] ) )
        update_usermeta($current_user->id, 'memberlocation', esc_attr( $_POST['memberlocation'] ) );
   if ( !empty( $_POST['skype'] ) )
        update_usermeta($current_user->id, 'skype', esc_attr( $_POST['skype'] ) );



    /* Redirect so the page will show updated info. */
    if ( !$error ) {
        wp_redirect( get_permalink() );
        exit;
    }


global $wpdb;

global $current_user;
$current_user = wp_get_current_user();

$user_id = wp_get_current_user();
$nickname = 'testname';
update_user_meta($user_id, 'nickname', $nickname);


}


?>

Code for form:

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
        <div id="post-<?php the_ID(); ?>">
            <div class="entry-content entry">

My question

How do I force the display_name to be updated whenever the nickname is updated in my custom page template?

I don't have time to test your code and respond, just wanted to take a moment and say this is a good example of a well formed question, and as such is worthy of the upvote i gave it.. –  t31os Dec 3 '11 at 14:59

I'm not 100% sure if I follow the logic of your question. But this is probably what you need:

if ( !empty( $_POST['nickname'] ) ) {
    wp_update_user( array ('ID' => $current_user->id, 'display_name' => esc_attr( $_POST['nickname'] ) ) ) ;
    update_user_meta($current_user->id, 'nickname', esc_attr( $_POST['nickname'] ) );
    update_user_meta($current_user->id, 'display_name', esc_attr( $_POST['nickname'] ) );
}

Attention: update_usermeta has been deprecated and you should use update_user_meta.

Also, I really don't know why there is a display_name in both tables, wp_users and wp_users_meta, but I guess this deserves a question of its own.

I believe this lines in your code are for testing or some left over, as I can't see their usefulness and the $current_user/$user_id part is plainly wrong...

global $wpdb;

global $current_user;
$current_user = wp_get_current_user();

$user_id = wp_get_current_user();
$nickname = 'testname';
update_user_meta($user_id, 'nickname', $nickname);
