Question

我有一份注册表格和登录表格。我在我的注册表单中使用了md5加密，它工作正常。但是，当我尝试使用真实密码（如123）登录时，它并没有登录我。另一方面，当我在密码字段中复制粘贴md5加密时，它就会登录我。请帮我解决这个问题！谢谢！

这是我的编码：

<?php
        if (isset($_POST['submit'])) {

            $user_name = $_POST['username'];
            $user_email = $_POST['email'];
            $user_pass = $_POST['password'];

            $query = "SELECT * FROM users where Email = '" . $_POST["email"] . "'";
            $result = $obj->run_query($query);

            if ($count = mysqli_num_rows($result) == 0) {

                $query = "INSERT INTO users (Name,Email,Pass) VALUES ('$user_name','$user_email', md5('$user_pass'))";
                $result = $obj->run_query($query);

                echo "<script>alert('You have successfully Registered!')</script>";
                echo "<script>window.open('welcome.php','_self')</script>";

            } else {

                echo "<script>alert('This user email $user_email is already exist!')</script>";
            }
        }

    // login script
    if (isset($_POST['login'])) {

        $name = $_POST['name'];
        $email = $_POST['email'];
        $password = $_POST['pass'];

        $query = "SELECT * FROM users WHERE Email = '$email' AND Pass = '$password'";
        $result = $obj->run_query($query);

        if ($count = mysqli_num_rows($result) > 0) {

            $_SESSION['email'] = $email;
            $_SESSION['name'] = $name;

            echo "<script>window.open('welcome.php','_self')</script>";



        }
        else 
        {
            echo "<script>alert('Your email or password is incorrect!')</script>";
        }
    }

?>
