WHMCS Small Custom Order Page w/ajax call

Hello Bidders, ==== Only experienced WHMCS customizers please ======= (You should already understand how WHMCS works) I need a Custom Order Form for WHMCS. I have already completed the styling. You can view styling and overall form mechanism at: [login to view URL] A few specifications that the form needs to do in order to work: 1) It needs to make an ajax call and verify that a subdomain not already in the system. 2) It needs to create the account with only this information. (the module and email template within WHMCS will handle the rest) Here are some suggestions (but you may decide to do it differently): ============================ TIPS=============================== I can give your developer a heads up on what needs to be done though: Duplicate an order form, then hide all the other fields & fill them in with a certain field which you can verify later to see if they have ever been changed by the user once in WHMCS Client Area. The fields on there such as subdomain will need to be custom fields, and also validated. Also, make sure they have a product in their cart, but that will be hidden. You could either have a page which will support backward compatibility with non-JS Users so it will check the sub domain is free, and then send them to the cart with the domain already filled in. It might be worth taking a look at the AJAX order form too, you should get a better flow that way, make sure you don't forget about non JavaScript users though, otherwise you could end up having duplicate entries. Process the order, it's then handed over the the module to do the rest. ============================================End of Tips==================
