Question

那你好！我根本无法理解为什么这个登录页面不起作用。我之前在php 5.4的共享服务器上运行它。我将网站移动到我自己的服务器上，运行Ubuntu 12.04，apache 2.4.6，php 5.5。

我只是在下面显示整个登录文件，globals.php包含mysql连接，它有效。

如果我遗漏了任何信息，请告诉我。

只需在if语句中测试print语句，我认为在if（prepare）之后失败了。

问题是，在您尝试登录后，它会在该if语句后显示一个空白页面。

再次感谢您的所有帮助，如果我没有提供足够的信息，请告诉我。

我不知何故感觉它与mysqli连接vs mysql vs PDO有关？

尝试更改此

 $stmt->bind_param('ss', $user, $pass);
$stmt->execute();
$res = $stmt->get_result();
$row = $res->fetch_assoc();
if ($res->num_rows==1)
{
 $_SESSION['username'] = $user; 
$_SESSION['userid'] = $row['id'];
$_SESSION['type'] = 1;
$_SESSION['LAST_ACTIVITY'] = time();
print "<script>alert('You are logged in! Check the menu \"Admin\" section for more information!');</script>";
}

到

 $stmt->bind_param('ss', $user, $pass);
 $stmt->store_result();
 $stmt->execute();

if ($stmt->num_rows==1)
{
$stmt->bind_result($id, $username, $password);
$stmt->fetch();
print "<script>alert('You are logged in! Check the menu \"Admin\" section for more information!');</script>";
}

登录页面让人困惑，为什么这不起作用？
