Running a php code after script been successfully executed

Question

I have the following script

<script type="text/javascript">
    // This identifies your website in the createToken call below
  Stripe.setPublishableKey('');

    var stripeResponseHandler = function(status, response) {
      var $form = $('#payment-form');

      if (response.error) {
        // Show the errors on the form
        $form.find('.payment-errors').text(response.error.message);
        $form.find('button').prop('disabled', false);
      } else {
        // token contains id, last4, and card type
        var token = response.id;
        var appendedStripeToken = false;
        // Insert the token into the form so it gets submitted to the server
        $form.append($('<input type="text" name="stripeToken" />').val(token);  
        function handleCall() {
            if (!appendedStripeToken) {
                appendedStripeToken = true;
                phpCall();
            } 
         }      // and re-submit
      }
    };

function onSubmit() {
    var $form = $('#'+id_from_form);

    // Disable the submit button to prevent repeated clicks
    $form.find('input').prop('disabled', true);

    Stripe.card.createToken($form, stripeResponseHandler);

}

function phpCall() {
   $.ajax({
      url: 'paymentEmail.php',
      success: function (response) {//response is value returned from php (for    your example it's "bye bye"
        alert(response);
      }
   });
}
  </script>

Essentially the phpCall() should only execute after

$form.append($('<input type="text" name="stripeToken" />').val(token);  

to be executed again, the user would have to refresh or land on the page, and hit the submit button again.

The problem here is that when a user hit submit, then the php code gets executed, which is great but when the page refresh or user relands on the page the php code gets executed regardless if the submit button was clicked.

Below is the php code, where I would like to store the value of this input and post it on the php page

   <input type="text" name="stripeToken" />

php page:

 <?php


 $course_price_final = $_POST['course_price_final'];

 $course_token = $_POST['stripeToken'];
 $course_provider = $_POST['course_provider'];
 $user_email = $_POST['user_email'];
 $course_delivery = $_POST['course_delivery'];

 $order_date = date("Y-m-d");



 $insert_c = "insert into orders (course_title,course_price_final,course_provider,user_email,course_date,course_delivery,order_date,course_token) 
         values ('$crs_title','$course_price_final','$course_provider','$user_email','$course_date1','$course_delivery','$order_date','$course_token')";

 $run_c = mysqli_query($con, $insert_c); 

Update:

 <script type="text/javascript">
    // This identifies your website in the createToken call below
  Stripe.setPublishableKey('CODE');

    var appendedStripeToken = false;

var stripeResponseHandler = function(status, response) {
    var $form = $('#payment-form');

    if (response.error) {
        // Show the errors on the form
        $form.find('.payment-errors').text(response.error.message);
        $form.find('button').prop('disabled', false);
    } else {
        // token contains id, last4, and card type
        var token = response.id;
        handleCall(token);
    }
};

function handleCall(token) { 
    if (!appendedStripeToken) { 
        // Insert the token into the form so it gets submitted to the server
        $form.append($('<input type="text" name="stripeToken" />').val(token); 
        appendedStripeToken = true; 
        phpCall(); 
    } 
}

function onSubmit() {
    var $form = $('#payment-form'); // TODO: give your html-form-tag an "id" attribute and type this id in this line. IMPORTANT: Don't replace the '#'!

    // Disable the submit button to prevent repeated clicks
    $('#paymentSubmit').prop('disabled', true); // TODO: give your html-submit-input-tag an "id" attribute

    Stripe.card.createToken($form, stripeResponseHandler);
}

function phpCall() {
    $.ajax({
        url: 'paymentEmail.php',
        success: function (response) { // response is value returned from php (for your example it's "bye bye")
            alert(response);
        }
    });
}
  </script>

update 2

two minor issues: With the button being disabled after a click, it wont allow to click again if for instance an error is returned as shown above. It should only disable it after the input has been released

$form.append($('').val(token));

Answer 1

It might help you :

function phpCall() {
 if( appendedStripeToken === true ){
   $.ajax({
    type: "POST",
    data: {run: true},
    url: 'paymentEmail.php',
    success: function (response) {//response is value returned from php (for    your example it's "bye bye"
        alert(response);
    }
   });
 }
} 

Answer 2

Try sending a variable via POST to your PHP:

function phpCall() {
   $.ajax({
      type: "POST",
      data: {run: true},
      url: 'paymentEmail.php',
      success: function (response) {//response is value returned from php (for    your example it's "bye bye"
        alert(response);
      }
   });
}

And then in your php:

if ($_POST['run']) {

    $course_price_final = $_POST['course_price_final'];
    $course_token = $_POST['stripeToken'];
    $course_provider = $_POST['course_provider'];
    $user_email = $_POST['user_email'];
    $course_delivery = $_POST['course_delivery'];
    $order_date = date("Y-m-d");
    $insert_c = "insert into orders (course_title,course_price_final,course_provider,user_email,course_date,course_delivery,order_date,course_token) 
             values ('$crs_title','$course_price_final','$course_provider','$user_email','$course_date1','$course_delivery','$order_date','$course_token')";
    $run_c = mysqli_query($con, $insert_c);
}
