我已经解决了这个问题……HURRAHHH没有会话&没有Cookie
i have solved the problem ... HURRAHHH with no session & no cookies
该解决方案是PHP:AJAX:JavaScript的组合
the solution is a combination of PHP : AJAX : JavaScript
您要在Page Load&上运行的查询不在页面上刷新通过AJAX调用运行，可以说我的功能是
the query that you want to run on Page Load & not on page Refresh run it as via AJAX call lets say my function for doing that is
function runQUERY()
{
xmlhttp=new XMLHttpRequest();
xmlhttp.open("POST","doIT.php",false);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send();
}
通过执行以下操作，我可以简单地使用Javascript来检查页面是新加载还是刷新.
and i can simply check with Javascript that the page is a fresh load or its a refresh by doing the following
<head>
<script type="text/javascript">
function checkRefresh()
{
if( document.refreshForm.visited.value == "" )
{
// This is a fresh page load
alert ( 'Fresh Load' );
document.refreshForm.visited.value = "1";
..call you AJAX function here
}
else
{
// This is a page refresh
alert ( 'Page has been Refreshed, The AJAX call was not made');
}
}
</script>
</head>
<body onLoad="checkRefresh()">
<form name="refreshForm">
<input type="hidden" name="visited" value="" />
</form>
</body>
</html>
，然后在您的 doIT.php 中，简单地添加要放入普通页面中的PHP代码
and in your doIT.php simple add your PHP code which you were going to put in the normal page
<?php
mysql_query("UPDATE---------");
//put any code here, i won't run on any page refresh
?>
