Jquery Modal form with in-line validations

I have been building an app and have encountered a road block related to AJAX form submission. I am having trouble including in-line validations and getting the form to submit. The big questions are: -where to put and how to implement validations for the new user/transaction modal form -how to submit the modal form -how to update the page after form submission My app is integrated with Stripe for payments. I am using client_side_validations gem for in-line form validation. Here's the user flow: 1. Non-user clicks the "buy" button for a post 2. 'transactions/form' modal dialog form opens: contains a form that creates a new transaction and optionally- a new user (registration) 3. form contains stripe credit card fields and optional password/email fields, also contains hidden fields for information about the post (id, price, etc...) 4. User has two options: a. enter only credit details b. enter credit details and password/email, i.e. register 5. click submit 6. IF: option a, only credit details have been entered - validate card - charge credit card - close modal and make appropriate changes to the page 7. IF: option b, credit card + registration details have been entered - validate card and user details - create user - create customer and charge customer - close modal and make appropriate changes to the page 8. the post is changed from 'active' to 'inactive' If you take on the job, I'll add you as a contributor to my private github repo The files and line numbers that need work are: [login to view URL] line: 43- the create action [login to view URL] [login to view URL] pages/[login to view URL] line: 24 transactions/[login to view URL] Would be forever indebted to you if you could take on this job, or at the very least take a look at my code and suggest something.
