我正在尝试限制评论和对评论的回复，并在达到限制后显示错误消息。我已成功限制评论和评论回复，并在仅提示评论而不是评论回复时成功提供了错误消息。

评论回复有一点 jquery 与他们一起工作，所以这是我能看到的唯一会导致消息不显示的事情。我尝试了其他方法，然后是当前使用的方法。

$valid = true;
$max_post_per_day = 5;
$max_reply_per_day = 5;

//THE REGULAR COMMENTS STRUCTURE THAT IS SHOWING THE ERROR MESSAGE PROPERLY

$query = "SELECT COUNT(*) FROM `cysticBlogComments`
              WHERE `userID` = $auth->id
                AND `date` = CURDATE()";
    $result = mysql_query($query, $connection);
    $post_count = mysql_result($result, 0);
    $error_msgs_max_comment[] = "Whoops! You have reached the maximum amount of comments allowed for the day.";

    if($post_count >= $max_post_per_day)
    {
        $valid = false;
    }
    else
    {

    $query = "INSERT INTO `cysticBlogComments` 
                                    ( `blogID`,

PHP 在执行 JavaScript 之前在服务器上运行，因此两者无法交互。JavaScript可能与 PHP 生成的 HTML 存在问题（换句话说，只有一个 JavaScript 错误），或者 HTML 本身可能包含错误，例如缺少结束符>或引号。

看起来您在第二次通话<?php后没有正确关闭标签。mysql_query()您正在打开一个新<?php标签，但我没有看到前一个<?php标签被关闭。
