注意:未定义的索引:HTTP_REFERER
$http_referer = $_SERVER['HTTP_REFERER']
我从教程中使用了这个,它看起来还不错
也代码从包含文件调用它
我应该改变什么?
我添加了print_r($_SERVER);现在页面给了我这个

已编辑代码,但仍无法回显所有需要的 fiedd
<?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">

<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“所有字段均为必填字段”
但即使填写所有字段消息也不会更改
