您好，

一切正常，除了在登录页面，它登录任何电子邮件甚至未注册...

Hello,
I have a big problem with my php script, i am making a simple login/register in php and mysql.
Everything works fine except that in the login page it logins any email even unregistered...

include("connect.php");
include("functions.php");


$error = "";
 if(isset($_POST['submit'])) //this line means that if the submit button is pressed do the following code.
 {

     $email = mysqli_real_escape_string($con,$_POST['email']);
     $password = mysqli_real_escape_string($con,$_POST['password']);

     if(email_exists($email,$con))
     {
         $result=mysqli_query($con,"SELECT password FROM users WHERE email='$email'");
         $retrievePassword=mysqli_fetch_assoc($result);

         if(md5($password)!==$retrievePassword['password'])
         {
             $error="Password is inccorect";
         }
     }
     else
     {
         $_SESSION['email']=$email;
         header("location: profile.php");
     }
}
?>
