我正在构建一个模板页面，用于提交配置文件更改。我想以绿色显示一条“正确”的消息（示例），让用户知道。

这里是我的模板代码：

<?php
global $avia_config;
/**
 * Template Name: User Profile
 *
 * Allow users to update their profiles from Frontend.
 *
 */

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

/* Load the registration file. */
require_once( ABSPATH . WPINC . \'/registration.php\' );
$error = array();
$correct = array();    
/* 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_user_meta( $current_user->ID, \'user_url\', esc_url( $_POST[\'url\'] ) );

    if ( !empty( $_POST[\'nickname\'] ) )
        update_user_meta( $current_user->ID, \'nickname\', esc_attr( $_POST[\'nickname\'] ) );

    if ( !empty( $_POST[\'description\'] ) )
        update_user_meta( $current_user->ID, \'description\', esc_attr( $_POST[\'description\'] ) );

    /* Redirect so the page will show updated info.*/
  /*I am not Author of this Code- i dont know why but it worked for me after changing below line to if ( count($error) == 0 ){ */
    if ( count($error) == 0 ) {
        $correct[] = __(\'Correct message\', \'profile\');
        //action hook for plugins and extra fields saving
        do_action(\'edit_user_profile_update\', $current_user->ID);
        wp_redirect( get_permalink() );
        exit;
    }
}
    /*

     */
     get_header();


     if( get_post_meta(get_the_ID(), \'header\', true) != \'no\') echo avia_title();
     ?>
