wordpress - 在 WordPress 上提交评论后出现自定义 'success' 消息

Question

我需要在 WordPress 上成功发布评论时显示一条成功消息。这个怎么做？

Answer 1

无需 Ajax 或插件。添加到function.php:

add_action( 'set_comment_cookies', function( $comment, $user ) {
    setcookie( 'ta_comment_wait_approval', '1', 0, '/' );
}, 10, 2 );

add_action( 'init', function() {
    if( isset( $_COOKIE['ta_comment_wait_approval'] ) && $_COOKIE['ta_comment_wait_approval'] === '1' ) {
        setcookie( 'ta_comment_wait_approval', '0', 0, '/' );
        add_action( 'comment_form_before', function() {
            echo "<p id='wait_approval' style='padding-top: 40px;'><strong>Your comment has been sent successfully.</strong></p>";
        });
    }
});

add_filter( 'comment_post_redirect', function( $location, $comment ) {
    $location = get_permalink( $comment->comment_post_ID ) . '#wait_approval';
    return $location;
}, 10, 2 );
