<?php session_start(); $uid = $_POST["uid"]; $pwd = $_POST["pwd"]; require_once "./DBDA.class.php"; $db = new DBDA(); $sql = "select pwd from users where uid='{$uid}'"; $mm = $db->StrQuery($sql,0); if(!empty($pwd) && $pwd==$mm){ $_SESSION["uid"] = $uid; header("location:RBmain.php"); }else{ echo "<script>alert('用户名或密码有误!')</script>"; }
5.最后做用户的主页面RBmain.php
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>权限主页面</title> </head> <body> <?php session_start(); if(empty($_SESSION["uid"])){ header("location:RBlogin.php"); exit; } $uid = $_SESSION["uid"]; require_once "./DBDA.class.php"; $db = new DBDA(); //子查询 $sql = "select * from roleswork where code in (select * from roles_roleswork where rolesuid in (select * from users_roles where usersuid='{$uid}'))"; $arr = $db->query($sql,0); foreach($arr as $v){ echo "<div>{$v[1]}</div>"; } ?> </body> </html>
效果如图：
