我有一个问题。。。我有这3个文件：

$keimeno = $post['keimeno'];
$author = $post['author'];
$postdate = $post['postdate'];
$postid = $post['postid'];

我的问题是，在ajax.php中，我把这个代码$idpost=$_GET['id']；我想从home.php中获取url id，并说未声明。。。问题是，在postreadmore.php中，它运行得非常完美。。。但我想要它，而且在ajax.php中……我知道问题是ajax.php从jquery脚本调用，无法获取id……我想问是否有我不知道的方法可以获取id。。。我已经搜索过了，但没有找到类似的东西！我放了一些带3个星号的零件，尽可能地让它更容易。。抱歉所有这些代码！提前感谢！
您可以使用会话变量设置ID，而在Ajax页面上只需取消设置会话变量。
