我没有想法，现在一直在寻找一段时间，所以希望有人能指出我正确的方向。
我有一个允许用户选择特定值的选择框。然后尝试使用 URL/值加载页面并继续接收空白页面。
假设没有传递任何值，它可以工作。我过去以同样的方式使用过这个页面很多次，所以我不确定出了什么问题。此外，如果传递了特定的 URL 参数，它似乎只会失败。我删除了问题区域之外的大量代码，以使其更易于阅读。
所以 $('#sheetDiv').load('loaddates.php'); 将起作用并且 $('#sheetDiv').load('loaddates.php?project_name=' + value); 将不会
主页代码如下：
<?php
session_start();
include('db.php');
if($_POST[submit]=="Submit")
{
mysql_query("INSERT INTO tblusers SET username='".$_POST[username]."',password='".$_POST[password]."',type='".$_POST[type]."'") or print mysql_error();
}
function make_star($x)
{
$s="";
for($i=1;$i<=strlen($x);$i++)
{
$s.="*";
}
return $s;
}
?>
