I am trying a different tact on a problem I am trying to solve. I have a form where I gather demographic information and a payment amount. I then need to calculate a hash, sequence, and timestamp in a way that is not visible to browser, then update hidden form values with these calculated fields and then submit to payment processor.
What I am trying currently is to have the main page with my form with the input and hidden fields, when submit is clicked, a jquery function runs, does an ajax post to a calculation php which uses an input of amount, which is part of the hash. The calculation php calculates the items then passes a json array back.
I then want to parse the return, update the hidden form values, then submit.
I will attach my code below, but right now, I am interrupting the post, passing the value to the calculation php and building the array. At that point, my process stops, it seems I am not returned to main page to update values and post.
What have I done incorrectly? Also, if you have a better solution, I would be interested to hear. Thanks
