Question

我正在尝试限制评论和回复评论，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，并在仅提示评论时成功提供了错误消息，而不是评论回复。

评论回复中有一些jquery与他们合作，所以我唯一能看到的就是导致消息无法显示。我尝试过其他方法，然后使用当前正在使用的方法。

$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`,

    mysql_query($query, $connection);

//THE JS FOR THE REPLIES

<script type="text/javascript">

            $("a.reply_link").click( function() {
                $("#"+$(this).attr('name')).fadeIn('slow');
            });

            $(".respond_nevermind a").click( function(event) {
                event.preventDefault();
                var reply_box = document.getElementById($(this).attr('href'));
                $(reply_box).css('display','none');

                var reply_textarea = document.getElementById($(this).attr('href')+"_textarea");
                $(reply_textarea).val('');
            });
        });
</script>

Answer 1

PHP在执行JavaScript之前在服务器上运行，因此两者无法进行交互。 JavaScript 可能与PHP生成的HTML有问题（换句话说，只有JavaScript错误）或HTML本身可能包含错误，例如缺少关闭{{1}或引用。

Answer 2

在第二次<?php通话后，您似乎没有正确关闭mysql_query()代码。您正在打开一个新的<?php代码，但我没有看到之前的<?php代码被关闭。

jquery会干扰php吗？
