注意：未定义的索引：HTTP_REFERER

$http_referer = $_SERVER [‘HTTP_REFERER’]

我使用这个从教程,它看起来不错

代码也从包含文件中调用它

我该怎么改？

我添加了print_r($_ SERVER);现在页面给了我这个

编辑代码,但仍然无法回应所有fiedds是必需的

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';

}

}

?>

Username:

Password:

Password again:

Firstname:

Surname:

} elseif (loggedIn()) {

echo 'you \'re already logged in';

}

?>

现在加入

“e”

页面说“所有字段都是必需的”

但即使填写所有字段消息也不要更改
