直接这样$_COOKIE['username'] 不能打印出来登陆的用户名啊 我想用这个用户名怎么办呢？
登录页
<?php
$pdo=new PDO("mysql:host=localhost;dbname=t1;","root","");
if(isset($_POST['submit'])){
$stmt=$pdo->prepare("select id,username,password from user where username=? and password=?");
$stmt->execute(array($_POST['username'],($_POST['password'])));
if($stmt->rowCount()>0){
list($id,$username)=$stmt->fetch(PDO::FETCH_NUM);
$time=time()+24*60*60;
setCookie("uid",$id,$time,"/");
setCookie("username",$username,$time,"/");
setCookie("isLogin",1,$time,"/");
echo '<script>location="blog.php"</script>';
}
else{
echo "登陆失败";
}
}
?>
<html>
<head>
</head>
<body>
<form action="login.php" method="post">
用户名：<input type="text" name="username">
密码：<input type="text" name="password">
<button type="submit" name="submit">登录</button>
</form>
</body>
</html>没人啊。。。。。。。。。。
你得先在登录成功的时候写一下COOKIE，写完了再访问新的页面，你的php代码才能读到它
