PHP会话不能使用JQuery Ajax？

我正在写一个浏览器gomoku游戏.我有ajax声明,允许玩家玩一块.

$(document).ready(function() {
    $("td").live('click',function(){
        var value = $(this).attr('id');
        $.get('includes/boardControl.php',{play: value,bid: bid});
    });
});

value =董事会的平方位置
bid =董事会ID

在为玩家识别创建用户登录之前,服务器端php有一个临时解决方案.它会在点击时旋转方块的片段状态,而不是知道要为其创建的播放器.

在创建登录内容后,我为玩家的ID设置了一个会话变量.我希望在ajax请求期间从php读取会话ID,并找出他们来自哪个播放器.

session_start();

…

$playerId = $_SESSION['char'];
    $Query=("SELECT p1,p2 FROM board WHERE bid=$bid");
    $Result=mysql_query($Query);
    $p1 = mysql_result($Result,"p1");
    $p2 = mysql_result($Result,"p2");
    $newPiece = 0; //*default no player
    if($playerId == $p1)
        $newPiece = 1;
    if($playerId == $p2)
        $newPiece = 2;

出于某种原因,当我运行完整的Web应用程序时,即使在我删除代码以使它们循环之后,这些部分仍会循环.
此外,登录后如果我在浏览器中手动加载php页面,它会正确修改数据库(它只播放属于该播放器的片段)并输出正确的结果.

在我看来,当与Ajax一起使用时,会话不会被转移.然而谷歌搜索告诉我,会话确实与Ajax一起工作.

更新：我正在尝试提供更多信息.

希望这些额外的信息有所帮助,我已经没有想法告诉你什么了.我应该加载完整的代码吗？

更新2：

在检查了火灾中的Ajax响应后,我意识到“播放”请求没有得到结果,并且在下一次“更新”之前电路板不会更新.我还在调查这个,但我也会在这里发布给你们.

boardUpdate.php
值得注意的地方是：
刷新板(第6行)
放置件(第20行)
function boardUpdate($turnCount)(第63行)
