哥们，需要在table外面套上form标签才行，<form action="index.php" method="post" enctype="multipart/form-data"></form>

再附上小弟自己的index.php代码:
<?php
require("dir.func.php");
require("file.func.php");
//require("common.func.php");
$path = "file";
$act = $_REQUEST['act'];
$filename = $_REQUEST['filename'];
$info =readDirectory($path);
//print_r($info);
//$redirect="index.php?path={$path}";
if($act=="创建文件"){
//创建文件
//echo $path."--";
//echo $filename;
//$mes = createFile($path."/".$filename);
//alertMes($mes,$redirect);
echo $path."--";
echo $filename;
}
?>
