注意：未定义索引：HTTP_REFERER
$http_referer = $_SERVER['HTTP_REFERER']
我在教程中使用了这个，看起来还不错
代码还从包含文件中调用它
我应该改变什么？
我添加了 print_r($_SERVER);现在页面给了我这个

编辑了代码但仍然无法回显所有需要的字段
<?php
ini_set("display_errors", true);
error_reporting(E_ALL);
require 'core.inc.php';
if(!loggedIn()) {
//check mikunim ke tamame field ha dar form vojod darand va set shudan
if(isset($_POST['username'])&&isset($_POST['password'])&&isset($_POST['password_again'])&&isset($_POST['firstname'])&&isset($_POST['surename'])) {
$username = $_POST['username'];
$password = $_POST['password'];
$password_again = $_POST['password_again'];
$firtsname = $_POST['firstname'];
$surename = $_POST['surename'];
//HALA CHECK MIKUNIM KHALI HASTAND YA NA
if(!empty($username)&&!empty($password)&&!empty($password_again)&&!empty($firstname)&&!empty($surename)){
echo 'ok' ;
} else {
echo ' All fields are required';
}
}
?>
<form action="register.php" method="POST">
Username:<br> <input type="text" name="username"><br> <br>
Password:<br> <input type="password" name="password"><br><br>
Password again:<br> <input type="password" name="password_again"><br><br>
Firstname:<br> <input type="text" name="firstname"><br><br>

<input type="submit" value="register">
</form>
<?php
} elseif (loggedIn()) {
echo 'you \'re already logged in';
}
?>
现在添加后
"e"
页面显示“所有字段均为必填”
但即使填充所有字段，消息也不会改变
HTTP_REFERER http://php.net/manual/en/reserved.variables.server.php不保证由客户端发送：
将用户代理引导至当前页面的页面地址（如果有）。这是由用户代理设置的。并非所有用户代理都会设置此项，有些用户代理提供了修改 HTTP_REFERER 的功能。简而言之，它确实不能被信任。
在你的情况下，很明显not正在发送，所以您实际上所能做的就是
if(isset($_SERVER['HTTP_REFERER'])) {
//do what you need to do here if it's set
}
else
{
//it was not sent, perform your default actions here
}
