<script>
                $(document).ready(function(){
                    $('#reg_form').parsley();
                    $('#reg_form').on('submit',function(event){
                        event.preventDefault();

                        if($('#reg_form').parsley().isValid())
                        {
                            $.ajax({
                                url:"db.php",
                                method:"POST",
                                data:$(this).serialize(),

                                beforeSend:function(){
                                $('#submit').attr('disabled','disabled');
                                $('#submit').val('submitting the value');
                                },
                                    success:function(data){
                                        $('#reg_form')[0].reset();
                                        $('#reg_form').parsley().reset();
                                        $('#submit').attr('disabled',false);
                                        $('#submit').val('submit');
                                        $('#message').html(data);

                                    }

                            });
                        }
                    });
                });
            </script>

db.php

<?php

//user login
if(isset($_POST['email']))
{
        $email =  $_POST['email'];
        $password = $_POST['password'];

    $query = "SELECT * FROM tbl_register where email ='$email' AND password = '$password'";
    $result = mysqli_query($connect,$query);

    if(mysqli_num_rows($result)>0)
    {
        echo "login successfully completed";

    }
    else 
    {
        echo "login failed";
    }
}

?>

推荐答案

最好从服务器端传递是否成功登录的标志值.

Its better to pass flag value that login successfully or not from server side.

如果您要编写以下代码:

If you will write below code:

 if(mysqli_num_rows($result)>0)
    {
        echo 1;

    }
    else 
    {
        echo 0;
    }

然后在ajax调用中，您可以检查数据

And then in ajax call you can check data

 $.ajax({
                                url:"db.php",
                                method:"POST",
                                data:$(this).serialize(),

                                beforeSend:function(){
                                $('#submit').attr('disabled','disabled');
                                $('#submit').val('submitting the value');
                                },
                                    success:function(data){
                                         if(data==1){
                                        window.location = home.php
                                        }
                                       $('#reg_form')[0].reset();
                                        $('#reg_form').parsley().reset();
                                        $('#submit').attr('disabled',false);
                                        $('#submit').val('submit');
                                        $('#message').html(data);

}
});
