提交表单模式后显示成功消息

Question

I have a contact form linked with form-to-email.php to send emails. What happen is when you click submit it will redirect you to another page (new one) what I would like to have is to show/display the success message within the modal right after clicking the botton.

<div class="modal fade" id="modal-register" tabindex="-1" role="dialog" aria-labelledby="modal-register-label" aria-hidden="true">

and the form-to-email.php is the following:

<?php

/* Configuration */
$subject = 'Membership Enquiry'; // Set email subject line here
$mailto  = 'email here'; // Email address to send form submission to
/* END Configuration */

$name = $_POST['form-name'];

$phone = $_POST['form-phone'];

$person = $_POST['form-person'];
$booking = $_POST['form-booking'];

// HTML for email to send submission details

Answer 1

You're redirecting to thank-you.html. Add there the code (with the success message) and if you want it to be a modal just add the modal code:

<!--Success pop up Starts-->
<div class="modal fade" id="success_msg" role="dialog" tabindex="-1">
<div class="success">
  <div class="modal-dialog-success">
    <div class="col-xs-12 pade_none">
      <button type="button" class="close" onClick="closeConfirm();" data-dismiss="modal">&times;</button>
      <div class="col-xs-12 pade_none">
        <h2>Success!</h2>
        <p>Your message has been sent.</p>
      </div>
      <div class="col-xs-12 pad_none">
      </div>
    </div>
  </div>
</div>
</div>
<!--Success pop up ends-->

And launch a javascript when entering:

<body onload="myOnloadFunc();">

Your function should show modal:

function myOnloadFunc() {
    $('#success_msg').modal('show');
}

Answer 2

You do two things either use AJAX to send request to form-to-email.php script or create hidden iframe with id="email" name="email" and use target="email" in form tag, it will open your php script in iframe and execute it but it will not redirect to that page, then you can use

document.getElementById('email').addEventListener('load', function() {
    alert('Email Send Successfully');
});

instead of alert you can add toaster (green bar) to your modal.

PHP CODE

    <?php session_start();
    include('config/connect_database.php');

    $Username = '';

    if(isset($_POST['Login'])) {

        $Username = mysqli_real_escape_string($conn, $_POST['Username']);
        $Password = mysqli_real_escape_string($conn, $_POST['Password']);

        $sql = "SELECT Username, Password, Authority FROM user WHERE Username LIKE '$Username' AND Status LIKE 'Active'";

        $result = mysqli_query($conn, $sql);    

        if(mysqli_num_rows($result) > 0) {
            $username = mysqli_fetch_assoc($result);

            mysqli_free_result($result);
            mysqli_close($conn);

            if(($Username === $username['Username']) && (password_verify($Password, $username['Password']))) {

                $_SESSION['Username'] = $_POST['Username'];
                $_SESSION['Authority'] = $username['Authority'];

            } else {
                echo "<script>alert('Invalid Username or Password');</script>";         
            }
        } else {
            echo "<script>alert('Invalid Username or Password');</script>";     
        }   

    }
?>
