脚本宝典收集整理的这篇文章主要介绍了php – 注意：未定义的索引：HTTP_REFERER，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
$http_referer = $_SERVER [‘HTTP_REFERER’]
我使用这个从教程,它看起来不错
我该怎么改？
我添加了PRint_r($_ 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
<?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> Surname:<br> <input type="text" name="surename"><br><br> <input type="submIT" value="register"> </form> <?PHP } elseif (loggedIn()) { echo 'you \'re already logged in'; } ?>
现在加入
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
在你的情况下,显然没有被发送,所以你真的可以做的就是
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
}
