PHP登录只刷新页面没有错误
您好我的登录似乎有一个非常令人沮丧的问题，我似乎无法修复，因为没有错误输出。我好像已经修复了我的Mac上的这个问题，但我将确切的文件转移到我的Windows PC它再次停止工作。每当我尝试使用示例a@a.com和密码登录时，无论我尝试了多少次，似乎只是一遍又一遍地刷新页面。我想知道是否有人可以帮助解决此错误？ 我尝试将操作添加到login.php似乎没有任何区别。
表格的图片我从以下网站获取数据：
session.php文件：
<?php
include('config.php');
session_start();
$user_check = $_SESSION['login_user'];
$ses_sql = mysqli_query($conn,"select email_adress from customer where email_adress = '$user_check' ");
$row = mysqli_fetch_array($ses_sql,MYSQLI_ASSOC);
$login_session = $row['email_adress'];
if(!isset($_SESSION['login_user'])){
header("location:login.php");
}
?>
的login.php
<?php
include("config.php");
session_start();
if($_SERVER["REQUEST_METHOD"] == "POST") {
// username and password sent from form
$myusername = mysqli_real_escape_string($conn,$_POST['username']);
$mypassword = mysqli_real_escape_string($conn,$_POST['password']);
$sql = "SELECT customer_id FROM customer WHERE email_adress = '$myusername' and password = '$mypassword'";
$result = mysqli_query($conn,$sql);
$row = mysqli_fetch_array($result,MYSQLI_ASSOC);
$active = $row['customer_id'];
$count = mysqli_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
if($count == 1) {
$_SESSION['login_user'] = $myusername;
header("location: index2.php");
}else {
$error = "Your Login Name or Password is invalid";
}
}
?>

1 个答案:
答案 0 :(得分：1)
您运行查询：
$sql = "SELECT customer_id FROM customer WHERE email_adress = 'a@a.com' and password = 'a'";
这会返回$count = mysqli_num_rows($result);的多个结果，因此＆gt; 1。
所以你总是落入其他地方：
if($count == 1) {
$_SESSION['login_user'] = $myusername;
header("location: index2.php");
}else {
$error = "Your Login Name or Password is invalid";
}
尝试测试目的尝试：
if($count >= 1) {
$_SESSION['login_user'] = $myusername;
header("location: index2.php");
}else {
$error = "Your Login Name or Password is invalid";
}
ofc稍后您必须确保无法两次注册电子邮件地址。
其次，您可能希望转发到session.php而不是
header("location:session.php"); // instead of index2.php
