所以我的index.php有我的默认页面。它在 xampp 上运行良好。因此,我将整个网站上传到 1&1(我的域/托管提供商),当我尝试访问我的域时,我收到一个空警报,没有消息,页面完全空白。
我将文件名更改为index.html,网页加载得很好。所以我知道它一定是带有 .php 扩展名或我的代码的东西。
我还添加了一个名为 .htaccess 的文件,它仅包含:
DirectoryIndex index.php
这是我在index.php顶部的php代码(用*s替换敏感信息):
<?php
//Connect to a database
$host_name = "******.db.1and1.com";
$database = "db****";
$user_name = "dbo******";
$password = "***z.0**";
$connect = mysqli_connect($host_name, $user_name, $password, $database);
// echo("nice job");
//Take the values from the html form and assign them to variables
$ID = $_POST['name'];
$userpassword = $_POST['password'];
//If no passsowrd entered then go straight to index.php
echo "<script type='text/javascript'>alert($userpassword);</script>";
if ($userpassword == null) {
header("Location: http://localhost:82/index3.php");
die();
}
//Check to see if the password matches the hashes
if (md5($userpassword) === '******************'
or md5($userpassword) === '***********'
or md5($userpassword) === '****************'
or md5($userpassword) === '**************')
{
//Add the visitor name to our list
mysqli_query($connect, "INSERT INTO `WebsiteVisitors` (`Name`) VALUES ('$ID')") or die("Error in INSERT: ".mysqli_error($connect));
// echo "You have entered the correct password, congrats.";
// Start the session so they can access other pages
session_start();
$_SESSION['loggedIn'] = true;
// Redirect them to rest of site
header("Location: http://localhost:82/home.php");
die();
}
else {
header("Refresh: 0; url=index2.php");
echo "<script type='text/javascript'>alert(\"Wrong Password. Check your invitation card.\");</script>";
}
?>
最佳答案
由于 $_POST
请求仅在您提交表单后发出,因此您只需在 $_POST["name"情况下执行用户名和密码检查]
和 $_POST["password"]
存在。
因此在使用和操作之前给出一个 if 语句 if(isset($_POST['name']) && isset($_POST['password']))
$_POST
变量。另外 session_start()
应在脚本顶部给出。
下面是您的完整代码,包括检查
<?php
session_start();
// session start should be at top of your script
error_reporting(E_ERROR); // reports only errors
//Connect to a database
$host_name = "******.db.1and1.com";
$database = "db****";
$user_name = "dbo******";
$password = "***z.0**";
$connect = mysqli_connect($host_name, $user_name, $password, $database);
// $_POST request comes only when form is submitted in your case. So check for $_POST['name'] and $_POST['password']
if(isset($_POST['name']) && isset($_POST['password']))
{
$ID = $_POST['name'];
$userpassword = $_POST['password'];
//If no passsowrd entered then go straight to index.php
if ($userpassword == null)
{
echo "<script type='text/javascript'>alert("Empty Password");</script>";
header("Location: http://localhost:82/index3.php");
die();
}
//Check to see if the password matches the hashes
if (md5($userpassword) === '******************'
or md5($userpassword) === '***********'
or md5($userpassword) === '****************'
or md5($userpassword) === '**************')
{
//Add the visitor name to our list
mysqli_query($connect, "INSERT INTO `WebsiteVisitors` (`Name`) VALUES ('$ID')") or die("Error in INSERT: ".mysqli_error($connect));
$_SESSION['loggedIn'] = true;
// Redirect them to rest of site
header("Location: http://localhost:82/home.php");
die();
}
else
{
echo "<script type='text/javascript'>alert(\"Wrong Password. Check your invitation card.\");</script>";
header("Refresh: 0; url=index2.php");
}
}
?>
