我允许我的用户从他们的帐户和文件夹中删除自己的文件，但每当有人点击删除按钮时，网址会将他带到remove.php并离开myfiles.php并删除文件。
我只是想在不离开页面的情况下删除文件是我检查过但没有成功的代码功能：
的Ajax
<script>
function loadXMLDoc()
{
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
// use the xmlhttp.responseText however you need.
}
}
xmlhttp.open("POST", "remove.php?file=$actfolder&file=$file, true);
xmlhttp.send();
}
</script>

closedir($directory_handle);

此代码位于每个文件下：
<a href='remove.php?file=$actfolder&file=$file' title='Delete file '$file' from the server'>Delete</a>

答案 0 :(得分：0)
在remove.php结束时，您可以使用以下代码返回上一页：
header("Location:".$_SERVER["HTTP_REFERER"]);
