Question

我偶然发现了一些问题。我的checkuser.php不应该重定向到成员区域页面。

基本上login.html发送到checkuser.php，然后应该重定向到login_success.php

这里是代码`

<?
/* Check User Script */
session_start();  // Start Session

include 'db.php';
// Conver to simple variables
$username = $_POST['username'];
$password = $_POST['password'];

if((!$username) || (!$password)){
    echo "Please enter ALL of the information! <br />";
    include 'login_form.html';
    exit();
}

// Convert password to md5 hash
$password = md5($password);

// check if the user info validates the db
$sql = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password' AND activated='1'");
$login_check = mysql_num_rows($sql);

if($login_check > 0){
    while($row = mysql_fetch_array($sql)){
    foreach( $row AS $key => $val ){
        $$key = stripslashes( $val );
    }
        // Register some session variables!
        session_register('first_name');
        $_SESSION['first_name'] = $first_name;
        session_register('last_name');
        $_SESSION['last_name'] = $last_name;
        session_register('email_address');
        $_SESSION['email_address'] = $email_address;
        session_register('special_user');
        $_SESSION['user_level'] = $user_level;

        mysql_query("UPDATE users SET last_login=now() WHERE userid='$userid'");

        header("Location: login_success.php");
    }
} else {
    echo "You could not be logged in! Either the username and password do not match or you have not validated your membership!<br />
    Please try again!<br />";
    include 'login_form.html';
}
?>

任何帮助表示感谢。

Answer 1

你不应该在你之前回复/打印一些东西

header("Location: login_success.php");

Answer 2

删除$

 foreach( $row AS $key => $val ){
        $$key = stripslashes( $val );
 }

像这样：

foreach( $row AS $key => $val ){
        $key = stripslashes( $val );
 }

你看到的错误是什么？

如果是“输出已启动”，则检查db.php和checkuser.php两次，如果他们有任何字符标记<?php ?>，则会导致header无效。在大多数情况下，空间被遗忘在某处。

PHP检查用户脚本无法正常工作
