Custom Shop Product page

Project for Custom Product page in Prestashop 1.6 I have attached a link example of the basic functionality required for the product ordering/customisation page. [login to view URL] Scope of Functionality 01 - Validate Customisation form user inputs for width and height. Criteria a - Numbers input are inside range, if outside range produce warning. b - Option to select cm or mm c - If one dimension is over a number range, this will update the maximum of the other dimension. generated by total square meter max from database.(database flag item) d - Pop up warning if some products over a width and will be joined (database flag item) e - There will be different drop downs for product types, these already have a selection by product option. The select drop down statements alter total price by single fixed item and so by a total percentage This is not a standard Prestashop option and will need to be integrated to the price f - Price must dynamically (ajax) update when values change as per example attached. g - Create a link to another product category via an existing id key to see alternative category. ( select width and height values must be retained for new product) Order Page Scope a - Capture all selected variables inside the customer order. These should be accessible to all client history, invoice and order references inside the standard Prestashop backend environment b - Order passed to the Prestashop payment processing standard feature. c - Additional product/order variables are inside the product table. These need to also be saved against the order. They will be used to generate a factory order after order completed. Development a - I will have a complete online prestashop test environment with sample products for testing all variables. Each product will have a specific outcome list to ensure fast and smooth development. I will provide freelancer with detailed and specific tests to validate functionality. It is only the product page and order saving ad processing that need to be modified.
