首先權限管理肯定是需要登陸的，這里就簡單的寫一個登陸頁面。
簡單的登陸頁面login.php
<h1>登錄頁面</h1> <form action="logincl.php" method="post"> <input type="text" name="uid" /> <input type="password" name="pwd" /> <input type="submit" value="登錄" /> </form>
登陸處理頁面logincl.php
<?php session_start(); include("../FENGZHUANG/DBDA.class.php"); $db = new DBDA(); $uid = $_POST["uid"]; $pwd = $_POST["pwd"]; $sql="select pwd from users where uid='{$uid}'"; $mm = $db->StrQuery($sql); if($mm==$pwd && !empty($pwd)) { $_SESSION["uid"]=$uid; header("location:main.php"); }
登陸完成后進入主頁面main.php

<?php include("../FENGZHUANG/DBDA.class.php"); $db = new DBDA(); $type = $_POST["type"]; switch($type) { case 0: $uid = $_POST["uid"]; $sql = "select jueseid from userinjuese where userid='{$uid}'"; echo $db->StrQuery($sql); break; case 1: $uid = $_POST["uid"]; $juese = $_POST["juese"]; $sdel = "delete from userinjuese where userid='{$uid}'";//保存權限最簡單的辦法是先把其刪除，再重新添加。 $db->Query($sdel,0); $arr = explode("|",$juese); foreach($arr as $v) { echo $v; $sql = "insert into userinjuese values('','{$uid}','{$v}')"; $db->Query($sql,0); } echo "OK"; break; }
