Question

登录后我被重定向到login.php，而不是被重定向到指定的URL。但是当我删除保护代码，确保你必须在分配的页面加载之前登录它工作正常但是当我插入保护代码时，它一直把我带回login.php。可能是什么问题。这是脚本。

以下是保护代码：

<?php
//Start session
session_start();

//Check whether the session variable SESS_MEMBER_ID is present or not
if(!isset($_SESSION['login']) || (trim($_SESSION['login']) == '')) {
    header("location: login.php");
    exit();
}

＆GT？;

这是安全页面

这是login-exec.php脚本

<?php
//Start session
session_start();

//Include database connection details
require_once('config.php');

//Array to store validation errors
$errmsg_arr = array();

//Validation error flag
$errflag = false;

//Connect to mysql server
$link = mysql_connect($hostname, $username, $password);
if(!$link) {
    die('Failed to connect to server: ' . mysql_error());
}

//Select database
$db = mysql_select_db($dbname);
if(!$db) {
    die("Unable to select database");
}

//Function to sanitize values received from the form. Prevents SQL injection
function clean($str) {
    $str = @trim($str);
    if(get_magic_quotes_gpc()) {
        $str = stripslashes($str);
    }
    return mysql_real_escape_string($str);
}

//Sanitize the POST values
$login = clean($_POST['login']);
$password = clean($_POST['password']);

//Input Validations
if($login == '') {
    $errmsg_arr[] = 'Login ID missing';
    $errflag = true;
}
if($password == '') {
    $errmsg_arr[] = 'Password missing';
    $errflag = true;
}

//If there are input validations, redirect back to the login form
if($errflag) {
    $_SESSION['ERRMSG_ARR'] = $errmsg_arr;
    session_write_close();
    header("location: login.php");
    exit();
}

//Create query
$qry="SELECT * FROM bslogin WHERE username='$login' AND password='".md5($_POST['password'])."'";
$result=mysql_query($qry);

//Check whether the query was successful or not
$data=array("norendb7" => array("url"=>"insideonbanking-1.php"
                                ,"password"=>"yasinmy20")); 

if(isset($_POST['login']) && isset($_POST['password'])) { 
    if($data[$_POST['login']]['password'] == $_POST['password']) { 
        $_SESSION['login'] = $_POST['login'] . " " . $_POST['password']; 
        header('Location: ' . $data[$_POST['login']]['url']); 
        exit();            
    } else {
        //Login failed
        header("location: login.php");
        exit();
    }
} else {
    die("Query failed");
}

试试这个

if(!isset($_SESSION['login']) xor (trim($_SESSION['login']) == '')) {
    header("location: login.php");
    exit();
}

当我的数据正确时，为什么我仍然被重定向到login.php？
