jquery会干扰php吗？ [英] Does jquery interfere with php?

问题描述

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。

I am trying to limit comments and replies to comments and display an error message once the limit is reached. I have successfully limited comments and comment replies, and successfully provided the error message when prompted ONLY for the comments, and not the comment replies.

评论回复有一点点jquery与他们一起工作，这是我唯一能看到的导致消息不显示的东西。我尝试了其他方法，然后使用当前正在使用的方法。

The comment replies have a little bit of jquery working with them, so that's the only thing I can see that would be causing the message not to display. I have tried other methods then the one currently being used.

$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`,
                                      `userID`,

                                      '" . date("G:i:s") . "')";


    mysql_query($query, $connection);

}

<?php if(isset($_POST['commentBlogSubmit']) && $post_count >= $max_post_per_day ) {
                foreach($error_msgs_max_comment as $msg) { ?>

//THE JS FOR THE REPLIES

<script type="text/javascript">
        $(document).ready( function() {

            $.localScroll({ offset:{top:-40,left:0} });

            $("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>

推荐答案

PHP在执行JavaScript之前在服务器上运行，所以两者无法互动。 JavaScript 可能存在PHP生成的HTML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> 或引用。

PHP operates on the server before JavaScript is ever executed so the two can't be interacting. The JavaScript could be having issues with the HTML produced by the PHP, though (in other words, there's just a JavaScript error) or the HTML itself may contain an error such as a missing closing > or quote.
