jQuery移动登录，php，cookie无效

Question

I'm building web app aas my major project for degree. Simple login was working but now I'm trying to implement cookies and my script is not working for some reason. I need to find out why, but can't do for last 2h. Here is my question:

From login form variables are passed into my login script (no security for password or jql injection was implemented so far), when I press login errors comes up, "Error Loading Page", this is login script:

session_start();

$username = $_GET["name"];
$password = $_GET["password"];
$remember_me = $_GET['remember_me'];

include('mysql_connection.php');
mysql_select_db("jzperson_imesUsers", $con);

$res1 = mysql_query("SELECT * FROM temp_login WHERE username='$username' AND password='$password'");
$count1=mysql_num_rows($res1);

if(isset($_COOKIE['usr_IMes']) && isset($_COOKIE['psw_IMes'])){
                    $user_n = $_COOKIE['usr_IMes'];
                    $pasw_n = $_COOKIE['psw_IMes'];

                    $res2 = mysql_query("SELECT * FROM temp_login WHERE username='$user_n' AND password='$pasw_n'");
                    $count2=mysql_num_rows($res2);

                    if($count2 == 1){

                                    $_SESSION['username'] = $user_n;

                                    header('Location: http://imes,jzpersonal.com/userpanel.php');

                    }else {
                                    setcookie('usr_IMes', $user_n, time() - 31*24*60*60);
                            setcookie('psw_IMes', $pasw_n, time() - 31*24*60*60);

                                    header('Location: http://imes,jzpersonal.com/index.html');
                    }

}else{

if($count1==1){
    $_SESSION['username'] = $username;

    if(isset($remember_me)){

setcookie('usr_IMes', $username, time() + 30*24*60*60);
setcookie('psw_IMes', $password, time() + 30*24*60*60);

header("Location: http://imes.jzpersonal.com/userpanel.php");
    }else{      

      header("Location: http://imes.jzpersonal.com/userpanel.php");

   }
}else{
    $login = "failed";
}
}

Can anyone see problem in my script? In login part? If not here is my authentication script on the start of every page, maybe my error is there:

session_start();

if(isset($_COOKIE['usr_IMes']) && isset($_COOKIE['psw_IMes'])){
                    $user_n = $_COOKIE['usr_IMes'];
                    $pasw_n = $_COOKIE['psw_IMes'];

                    $res2 = mysql_query("SELECT * FROM temp_login WHERE username='$user_n' AND password='$pasw_n'");
                    $count2=mysql_num_rows($res2);

                    if($count2 == 1){
                                    header('Location: http://imes,jzpersonal.com/userpanel.php');   
                    }else {
                                    setcookie('usr_IMes', $user_n, time() - 31*24*60*60);
                            setcookie('psw_IMes', $pasw_n, time() - 31*24*60*60);

                                    header('Location: http://imes,jzpersonal.com/index.html');
                    }

}else{

if(!isset($_SESSION['username']))
{
header('Location: http://imes.jzpersonal.com/index.html');
}

if(empty($_SESSION['username']))
{
header('Location: http://imes.jzpersonal.com/index.html');
}
}

Hope some error will be found, thank you for all your help.

Answer 1

The redirect is a bad url: http://imes,jzpersonal.com/userpanel.php - this would give you your "error loading page". Besides that, you should NEVER store username/password in cookies - it is a terrible practice because cookies can be viewed on the machine. Also, you are using the original PHP MySQL API which is deprecated - you should be using PDO or mysqli.
