Question

这是我的页面，它运行正常，我只想添加如何重定向页面，具体取决于帐户是管理员还是用户，请指出添加位置，以及是否有任何想法在我的MySQL数据库上进行更改，这将是有用的。

数据库：

id_number username password status
1         admin    admin    1
2         user     user     0

admin = 1
user = 0

            <?php 
             // Connects to your Database 
             mysql_connect("localhost", "root", "") or die(mysql_error()); 
             mysql_select_db("net25") or die(mysql_error()); 
             //Checks if there is a login cookie
             if(isset($_COOKIE['ID_my_site']))
             //if there is, it logs you in and directes you to the members page
             { 
                $username = $_COOKIE['ID_my_site']; 
                $pass = $_COOKIE['Key_my_site'];
                    $check = mysql_query("SELECT * FROM users WHERE username = '$username'")or die(mysql_error());
                while($info = mysql_fetch_array( $check ))  
                    {

                if ($_POST['pass'] != $info['password']) {
                    die('Incorrect password, please try again. <a href=index.php>Click Here to Log In</a>');
                }
                else 
             { 
             // if login is ok then we add a cookie 
                 $_POST['username'] = stripslashes($_POST['username']); 
                 $hour = time() + 3600;

Answer 1

if ($info['status'] == '1') { // check the value of the 'status' in the db
    //go to admin area
    header("Location: admin.php");
} else {
    //go to members area
    header("Location: main.php");  
}

应该这样做。

Answer 2

我会在原始行附近添加其他重定向：

header("Location: main.php");

可能在这样的if语句中：

if($info['status'])
{
    header("Location: admin.php");
}
else
{
    header("Location: main.php");
}

Answer 3

当您在数据库中创建用户定义时，定义“身份验证”为0或1.然后当他们登录时，您可以执行类似的操作。

logincheckpage.php

mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");
$sql="SELECT * FROM users WHERE u_name='$myusername' and p_word='$encrypted_p_word'";
$result=mysql_query($sql);
$row= mysql_fetch_array($result);
$count=mysql_num_rows($result);
$auth=$row['auth'];
if($count==1){
    if($auth==1){
        session_start();
        $_SESSION['auth']=$auth;
        $_SESSION['u_name']=$myusername;
        header("location:index.php");
    }
    elseif($auth==0){
        session_start();
        $_SESSION['auth']=$auth;
        header("location:calendar.php");
    }
}
else {
echo "Wrong Username or Password";
}

在其他页面的顶部，您不希望用户看到类似

的内容

session_start();
if($_SESSION['auth']!=1){
    header("location:login.php");
}

登录后重定向到管理员/用户页面
