Question

我正在进行简单的聊天。

我正在尝试使用ajax函数发送消息和chatid。但问题是该消息是唯一发送的消息。

我正在使用＆＃34;原型＆＃34; for ajax（http://prototypejs.org/）

表单提交给彗星函数，就像这样。

自：

@Point1.STUnion(@Point2).STConvexHull()

要：

<form action="" method="get" onsubmit="comet.doRequest($('word<?php echo $chatid?>').value, <?php echo $chatid?>);$('word<?php echo $chatid?>').value='';return false;">    
    <input type="text" name="word<?php echo $chatid?>" id="word<?php echo $chatid?>" value="" autocomplete="off"/>
    <input type="submit" name="submit" value="Send" />
</form>

然后到后端PHP文件，在那里它使用GET函数来收集数据。

   doRequest: function(request, request2)
  {
    new Ajax.Request(this.url, {
      method: 'get',
      parameters: { 'msg' : request, 'room' : request}
    }
    );
  }

消息通过虽然很好，但是当我尝试对房间做同样的事情时：

$msg = isset($_GET['msg']) ? $_GET['msg'] : '';
if ($msg != '')
{
  file_put_contents($filename,$msg);
  die();
}

我得到＆＃34; null＆＃34;

过去几个小时一直把头发拉出来！

完整代码：

$room = $_GET['room'];

backend.php

 <?php $chatid = 7 ?>
<form action="" method="get" onsubmit="comet.doRequest($('word<?php echo $chatid?>').value, <?php echo $chatid?>);$('word<?php echo $chatid?>').value='';return false;">    
            <input type="text" name="word<?php echo $chatid?>" id="word<?php echo $chatid?>" value="" autocomplete="off"/>
            <input type="submit" name="submit" value="Send" />
        </form>
