【问题描述】：
我想将这两个 ajax 调用结合起来，因为我希望能够将两个 post 变量存储在 url 中，因为在特定时间只能存储其中一个：
<script>
function showUser() {
var selectedPerson = $('#testform').serialize();
document.getElementById("txtHint").innerHTML = "<div class='loading-indication'><img src='ajax-loader.gif' /> Please wait... Loading New Courses...</div>";
$.ajax({
url:'getuser.php',
type:'post',
data:selectedPerson,
success:function(res){
$('#txtHint').html(res);
}
})
}
</script>
<script>
function showUser2() {
var selectedPerson = $('#testform2').serialize();
document.getElementById("txtHint").innerHTML = "<div class='loading-indication'><img src='ajax-loader.gif' /> Please wait... Loading New Courses...</div>";
$.ajax({
url:'getuser.php',
type:'post',
data:selectedPerson,
success:function(res){
$('#txtHint').html(res);
}
})
}
</script>
下面是php部分：
$person = isset($_POST['person']) ? $_POST['person'] : '';
$allIds = '';
if($person!='')
{
$allIds = implode(',', $person);
}
$person2 = isset($_POST['person2']) ? $_POST['person2'] : '';
$allIds2 = '';
if($person2!='')
{
$allIds2 = implode(',', $person2);
}
如果需要任何说明，请告诉我
更新：

如何调用
showUser和showUser2？ -
感谢您的回复。我在发布整个 html 页面的初始帖子下添加了一个更新，基本上我正在尝试实现这个w3schools.com/php/php_ajax_database.asp，但使用多个复选框而不是单个选择选项'
-
那么您必须使用会话将第一次调用的参数存储在服务器端。然而，这将是一个非常脆弱的解决方案。你能不能把第一个请求的参数和你要发送的参数一起发送？
-
您好，感谢您的询问。我知道它很脆弱，但我想使用会话，因为它可以让我更轻松地检索其他页面上的变量。我是这方面的新手，我将如何通过会话解决这个问题

为了您的礼貌，我还发布了整个 php 页面
