模态按钮包含帖子ID：
<button onclick='getValue("<?=$id?>");' data-toggle="modal" name="submit" data-target="#squarespaceModal">Purchase Now</button>
当我使用alert时，它会正确显示此ID，但我需要将此ID存储在 PHP 变量中
`function getValue(id){
alert(id);
// i am trying this but not done
// <?php $xyz = ?> id ;
}`
我也在尝试使用$.post，但在模式中数据不会出现
像
$.post( "<?=$current_url;?>", function( id ) {
// $( "#div1" ).html( id );
//alert(id);
});
我怎样才能将jquery值存储在php变量中？我见过的大多数例子都是相反的，比如var x =<?php echo $y;?>，但我需要相反。

你不能单独使用jQuery;你需要结合使用Ajax和PHP文件。例如： 的 HTML
<button onclick='getValue("<?=$id?>");' data-toggle="modal" name="submit" data-target="#squarespaceModal">Purchase Now</button>
<强>的jQuery
function getValue(id) {
// Send Ajax request to ajax_file.php, with id as POST data
$.post("ajax_file.php", {'id': id}, function(result){ alert(result)});
}
<强> ajax_file.php
<?php
session_start();
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$_SESSION['id'] = $_POST['id'];
echo $_SESSION['id'];
}
?>

</div>这里我已经对php文件进行了ajax调用，在该文件中，我在会话中存储了已发送的id，所以现在你在会话中的php变量中有了这个id
