使用所有不同的重定向页面创建登录会话
使用所有不同的重定向页面创建登录会话
提问于 2014-04-08 17:19:13
)我正在开发一个有3个用户(管理员、教师和学生)的登录系统，所有这些用户都有自己的功能和界面。如果可能的话，我想让所有这些用户一起登录one，我不确定。
我的数据库中有一个行角色(‘管理’，‘教师’，‘学生’)，我希望基于“角色”直接登录，所以管理员将被重定向到管理主页，教师重定向到教师主页，学生将重定向到学生主页。行政网页只能由管理员浏览，教师页面只能由教师浏览，学生页面只能由学生浏览。你大概明白我的意思了。
问题:我如何使登录，以便它将检查它是否是管理员/教师/学生？当他们登录时，我如何才能使该用户的特定主页仅由该类型的用户提供？
<?php
session_start();
$mysqli=new MySQLi("localhost", "root", "", "hws");
$role="";
$username=filter_input(INPUT_POST, 'username', FILTER_SANITIZE_STRING);
$password=filter_input(INPUT_POST, 'password', FILTER_SANITIZE_STRING);
if($query=$mysqli->prepare("SELECT `role` FROM members WHERE username=? AND password=?"))
{
$query->bind_param("ss", $username, $password);
$query->execute();
$query->bind_result($role);
$query->fetch();
}
else
{
echo "Errors in the Query. ".$mysqli->error;
die();
}
if($role!="")
{
$_SESSION['ingelogt']=$username;
$_SESSION['user_role']=$role;
$location="$role.php"; // If role is admin this will be admin.php, if student this will be student.php and more.
header("location: $location"); // Redirect to the respective pages.
}
else
{
echo "Invalid password, username combination";
}
?>对于userpage，一个例子
<?php
session_start()
if(!isset($_SESSION['ingelogt']))
{
header("location: index.php"); // The user is not logged in. Redirect him to the login page.
}
$page_role="leerling"; // This must be admin for admin.php and student for student.php and similar
$role=$_SESSION['user_role'];
if($role!=$page_role) // If student come to admin page by mistake or admin to student and similar
{
echo "You are not supposed to be here.";
die();
}
?>

由于我对事先准备好的陈述比较满意，所以我在这里使用了它。这是您的需求的一个简单逻辑示例。
<?php
session_start();
$mysqli=new MySQLi("localhost", "USER_NAME_HERE", "PASSWORD_HERE");
$role="";
$username=filter_input(INPUT_POST, 'username', FILTER_SANITIZE_STRING);
$password=filter_input(INPUT_POST, 'password', FILTER_SANITIZE_STRING);
if($query=$mysqli->prepare("SELECT `role` FROM members WHERE username=? AND password=?"))
{
$query->bind_param("ss", $username, $password);
$query->execute();
$query->bind_result($role);
$query->fetch();
}
else
{
echo "Errors in the Query. ".$mysqli->error;
die();
}
if($role!="")
{
$_SESSION['ingelogt']=$username;
$_SESSION['user_role']=$role;
$location="$role.php"; // If role is admin this will be admin.php, if student this will be student.php and more.
header("location: $location"); // Redirect to the respective pages.
}
else
{
echo "Invalid password, username combination";
}
?>
And in your admin.php, student.php
<?php
if(!isset($_SESSION['ingelogt']))
{
header("location: login.php"); // The user is not logged in. Redirect him to the login page.
}
$page_role="admin"; // This must be admin for admin.php and student for student.php and similar
$role=$_SESSION['user_role'];
if($role!=$page_role) // If student come to admin page by mistake or admin to student and similar
{
echo "You are not supposed to be here.";
die();
}
