我正在尝试创建一个与SQL数据库连接的基本登录页面。
但是，header('location: profile.php');没有重定向到指定的页面，而是admin_login页面刷新为空白状态。我花了一段时间在这里浏览了无数其他与类似问题相关的解决方案，但似乎没有解决我的问题。
干扰线似乎是在admin_login.php的顶部：
if ($_POST['submit']) {
当我移动上面的标题调用时，标题会执行并重定向到profile.php页面。
<?php
error_reporting(E_ALL & ~E_NOTICE);
session_start();
if ($_POST['submit']) {
include_once("connection.php");
$username = strip_tags($_POST["username"]);
$password = strip_tags($_POST["password"]);
$sql = "SELECT id, username, password FROM login WHERE username = '$username' AND activated = '1' LIMIT 1";
$query = mysqli_query($dbCon, $sql);
if ($query) {
$row = $mysqli_fetch_row($query);
$userID = $row[0];
$dbUsername = $row[1];
$dbPassword = $row[2];
}
if ($username == $dbUsername && $password == $dbPassword) {
$_SESSION['username'] = $username;
$_SESSION['id'] = $userID;
header('location: /profile.php');
exit();
} else {
echo "Incorrect username/password combo";
exit();
}
}
?>
<?php
$pageTitle = "Casa Mirador | Admin";
include_once('inc/header.php');
?>
<h2 style="text-align: center;">Admin Login</h2>
