会话控制

Question

有时会话不起作用，我只是需要一些建议和帮助。

登录代码：

<?php

if (isset($_POST['submit']))
{

$query = "SELECT wachtwoord, naam, status, email FROM leden WHERE email = '$username' AND wachtwoord = '$password' LIMIT 1";
$username = mysqli_real_escape_string($connect,$username);
$result = mysqli_query($connect,$query) or die(mysql_error());

while($row = mysqli_fetch_array($result)){
    $resusername = $row['naam'];
    $respassword = $row['wachtwoord'];
    $resemail = $row['email'];
    $resstatus = $row['status'];

}
    $teller = mysqli_num_rows($result);
    if ($teller == 1) {
        session_start();
        $_SESSION['email'] = $resemail;
        $_SESSION['naam'] = $resusername;
        $_SESSION['status'] = $resstatus;
        $_SESSION['start_time'] = time();
        echo "<div class=\"confirmation-box round\">Je bent nu ingelogd je word doorgestuurd in 3 seconden.</div>";
        echo "<meta http-equiv=\"refresh\" content=\"3;URL=**********/home_.php\" />";
        }else{
        echo "<div class=\"error-box round\">E-mail of wachtwoord komt niet overeen.</div>"; } }
?>

检查会话是否存在（打开）：

if (empty($_SESSION['naam'])){
die("Log eerst in voordat u deze pagina bezoekt.");
}

在每一页上：

ob_start();
session_start();

系统有时会出现故障，我做错了什么？欢迎提出建议，我的英语不是那么完美，所以如果你指点我一个方向，请说明你的意思，这样我就明白了。

没关系，切换到 cookie 会话是没用的。
