关于php的post的问题.：报错

 那叫GET

$_GET[' username']   $_GET[' password ']    

你看看你form表单中的method

如果是method="get"，在接收页面使用$_GET来接收

如果是method="post"，在接收页面使用$_POST来接收

把圣经再看3遍...

public function login($username,$password)
{
$username = clean($username);
$password = clean($password);
$encrypted_psword = hash("sha512", "$password");
$db_con=mysqli_connect("localhost","root","","Jobridge");
$result = mysqli_query($db_con,"SELECT * FROM usr_list WHERE Username='$username' AND Password='$encrypted_psword'");
$count = mysqli_num_rows($result);
if ($count == 1)
{
if(isset($_POST['rememberMe']))
{
setcookie('username', $username, time() + 604800, '/');
setcookie('password', $encrypted_psword, time() + 604800, '/');
}
else
{
setcookie('username', $username, time() + 3600, '/');
setcookie('password', $encrypted_psword, time() + 3600, '/');
}
$currentDate = date('Y-m-d g:i:s');
$result = mysqli_query($db_con,"UPDATE usr_list SET last_login = ' ". $currentDate ." ' WHERE username ='$username'");
?><script type="text/javascript">
function redirect() {
window.location='/Jobridge/login_page.php';
}setTimeout(redirect, 0);
</script><?php
}
else
echo "fail";
?><script type="text/javascript">
function redirect() {
window.location='/Jobridge/index.php';
}setTimeout(redirect, 2000);
</script><?php

}

上面是我一个class里面的一个function。。。。。。

下面是我创建对象。。然后调用这个方法的代码

<?php
include $_SERVER['DOCUMENT_ROOT'].'/controller/main_function.php';


$Jobridge = new Jobridge;
if(isset($_POST['username']) && isset($_POST['password']))
{
$username = $_POST['username'];
$password = $_POST['password'];
$Jobridge -> login($username, $password);
}
?>
这两个代码是在不同的文件里的。。。第二套是在login.php。。就是用来做验证的文件里面。

大伙好热心。。。
