フォームを送信した後に「正しい」メッセージを表示する方法

Question

プロファイルの変更を送信するためのテンプレートページを作成しています。ユーザーにわかりやすいように、「正しい」メッセージを緑色で表示します（例）。

ここに私のテンプレートコード：

<?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();

<?php get_footer(); ?>

解決しました。

Answer 1

私はその問題を解決した。最初にエラーがないかどうかを確認してから、次のようなカスタムリダイレクトURLを追加します。

if ( count($error) == 0 ) {
     wp_redirect( get_permalink() . '?updated=true' );
}

そして最後に 'GET'メソッドを使ってメッセージを追加しました：

<?php if ( $_GET['updated'] == 'true' ) : ?> <p class="form-submit-success" style="color: green">Your profile has been updated</p>
