urgent wordpress / woocommerce modification and zapier - UPDATED

Hi Guys, This project is quite small. I've started on it, but just haven't had time to finish it. I need this completed within the next 15 hours. Fixed price, only contact me if you can deliver this: I need the following functionality developed: TASK 1. Add regular price to the custom add-to-cart code. TASK 2. Query data is put into a custom billing field and pre-fills existing billing fields on the checkout page. TASK 3. Stripe 3D Secure Credit Card Processing Declining. TASK 4. All successful orders set to complete status. All failed order set to Pending. TASK 5. All order data is accessible via Zapier. TASK 1: Edit the attached code example: [login to view URL] The code currently works as: [login to view URL]:1,37:1 Where add-to-cart query is: <product ID>:<quantity>, I need this code to be updated so that the regular price is set for the products: [login to view URL]:1:1234.56,37:1:9876.54 Where add-to-cart query is: <product ID>:<quantity>:<regular_price>, TASK 2. A custom billing field "reference code" and existing field data in a query will need to pre-fill the checkout page: Query (including Task 1): [login to view URL]:1:1234.56,37:1:9876.54&rcode=ABC12355&fname=John&lname=Doe&email=jdoe%[login to view URL] The following Woocommerce Billing fields will be prefilled on the checkout page: - Reference Code (Custom Field) = rcode (ABC12355) - First Name = fname (John) - Last Name = lname (Doe) - Email = email (jdoe@[login to view URL]) TASK 3. When using 3D Secure on Stripe using the Woocommerce plugin, it allows you to set all cards to use 3D secure if it's supported or optional. However, I need the payment to not be processed (and for the order to be left in FAILED custom status) and the user to go to a thank-you page (Page ID 40). So to summaries: - Custom Status FAILED needs to be created - All orders must be forced to use 3D secure. - If 3D secure is not available on the card, then the Order returns as Pending status. - User goes to PAGE ID 40 (Failed Thank You Page). - If 3D secure payment succeeds, - User goes to PAGE ID 42 (3D Secure Success Thank You Page) So only 3D secure payments can succeed. No non-3D secure payments are processed. See here where Woocommerce developers advise how to do it: [login to view URL] TASK 4. On the result from processing the payment using 3D secure (Task 4): - If succesful change order status to Complete status - If failed (due to non-3D secure card - TASK 3), change to Pending status - If tailed (or any other failure such as declined, or insufficient funds), change to Failed status TASK 5. After Tasks 1-4 are done, I will test Zapier to see if the order info comes through. If it doesn't, a webhook will need to be posted to with all the order information. All of the above code must be done via [login to view URL] and no core code is to be modified so that upgrades can be made without impacting this code. I have also provided some of the code inside the functions.php. A development environment will be provided to you to complete the work. Sample code for the above is: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL]
