一段时间以来,我一直在努力解决这个错误。
我已经创建了一个个人资料站点,如果我在本地运行它,登录并重定向到个人资料页面没有问题。
但是很快我上传了它,当我按下登录时没有任何反应。我只是得到一个空页面......但是如果我打开页面源,我可以看到它正在读取我的 init.inc.php 文件。但只是阅读了评论代码。而且由于我不会收到任何错误消息,所以我真的不知道问题出在哪里。
aaa 希望你明白我想说的:)
这是我的登录页面
<?php 
 include 'core/inc/init.inc.php';
 if ($_SERVER['HTTP_HOST'] != 'localhost') // running in remote server
    $server = 'pixeltouch2.mysql.domeneshop.no';  
    else // running locally
    $server = 'pixeltouch2.mysql.domeneshop.no';
mysql_connect($server, "LOGIN", "pass") or die(mysql_error());
  mysql_select_db("pixeltouch2") or die(mysql_error()) ;
$errors = array();
if (isset($_POST['username'], $_POST['password'])){
    if(empty($_POST['username'])){
        $errors[] = 'The username cannot be empty.';    
    }
        if(empty($_POST['password'])){
        $errors[] = 'The password cannot be empty.';
    }
//Log in
    if (valid_credentials($_POST['username'], $_POST['password']) == false ){
        $errors[] = 'Username / Password incorrect.';
    }
        if (empty($errors)){
            $_SESSION['username'] = htmlentities($_POST['username']);
            $_SESSION['uid'] = fetch_user_id($_SESSION['username']);
            header("Location: profile.php?uid=" . $_SESSION['uid']);
                die();
                echo $_SESSION['uid'];

错误日志
Warning: Cannot modify header information - headers already sent by (output started at /home/3/p/pixeltouch/www/book/core/inc/init.inc.php:2) in /home/3/p/pixeltouch/www/book/login.php on line 32
When I look @ line 32 I its my  header("Location: profile.php?uid=" . $_SESSION['uid']);
                die();
                echo $_SESSION['uid'];
所以它与会话有关,是否有另一种方法来编写代码以使其工作?
