PHP设置cookie跳转页面后cookie值丢失

opopen 2015-08-12 10:48:17

问题就是，我输入正确的用户名和密码，还是照样让我重新登陆
在index.php页面获取不到cookie里面的值
主页是判断是否设置用户名，没有设置就返回设置，大牛们帮忙看下什么情况！

我贴一下代码:





<?php

//Login.php

//清空cookies

function clearCookies(){

		setCookie('username','',time()-3600);  //删除cookies中标识符为username的变量的值

		setCookie('isLogin','',time()-3600);      //删除cookies中标识符为isLogin的变量的值 

		setCookie('userpass','',time()-3600);      //删除cookies中标识符为userpass的变量的值 

}

//判断用户是否登录

	//if($_GET['action']=='login')

//	{

		clearCookies();

		$inputname = $_GET['loginname'];

		$inputpass = $_GET['loginpass'];

		echo '获取到用户名后立即输出'.$inputname.'</br>';

		echo '获取到密码后立即输出'.$inputpass.'</br>';

		//插入数据库

		$host = "localhost";

		$user = "root";

		$password = "";

		$dbname = "test";

		$connection = mysql_connect($host,$user,$password);

		//echo $connection;

		if($connection)

		{

			//$password = md5($password);

			echo '此处是密码'.$inputpass.'</br>';

			echo '此处是用户名'.$inputname.'</br>';

			

			mysql_select_db($dbname,$connection);

			echo "数据库链接成功了".'</br>';

			$sql = "   SELECT * FROM  `user_info`  where `uname`='$inputname' and `upass` = '$inputpass' ";

			echo $sql;

			$result = mysql_query($sql);

				if($result)

				{

					$row = mysql_fetch_array($result);

					if($row)

					{

						var_dump($row);

						setcookie("username",$row['uname'],time()+3600*24,'/');

						setcookie("userpass",$row['upass'],time()+3600*24,'/');

						setCookie('isLogin','login',time()+3600*24,'/'); 

						//echo $_COOKIE["isLogin"];

						//echo $checklogin;

						//echo $checkloginvalue;

						//$home_url = 'index.php';

						mysql_close($connection);

						//echo "<script language='javascript'> alert(\"欢迎您,${row}['uname']\");window.location='../index.html'</script>";

						header("location:index.php");

						

					}else

					{

						die("登录失败");

					}

				}

		}

		else{

				echo "数据库链接失败";

		}

		

	//}

	

?>

接下来是主页:index.php



<?php



	$username = $_COOKIE["username"]; 

	var_dump($username);

	echo '此处输出Cookie里面的用户名'.$username;

	if($username=="" || $username==null)

	{

					echo"我进来了";

					//header("location:login.html");

					

					exit;

	}

?>
