我已经创建了一个前端“编辑配置文件”模板。在昵称文本框中输入值时，仅更新昵称。默认的WordPress论坛有一个选择菜单，允许/要求用户选择其display\\u名称（昵称文本框，display\\u名称选择菜单）。
我的表单没有这样做，因为我无法找到强制昵称另外更新display\\u名称的方法（即，我有一个昵称文本框，但没有display\\u名称的选择菜单-我想自动执行此操作）。
display\\u名称存储在“users”表中。昵称存储在“users\\u meta”表中。
保存代码：
<?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 $current_user;
$current_user = wp_get_current_user();

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

当昵称在自定义页面模板中更新时，如何强制更新display\\u名称？
