Build a Website (wordpress)

Woocommerce have recently released their 'Bookings' extension and we need to make some customisations. Bookable products allow for a number of 'persons' to be specified when the customer is placing the order in the store. However, we need to capture additional information for each person. For example, if two people are entered (an example has been set up here: [login to view URL]) then two rows of fields should show as seen in this example here: [login to view URL] Rows of custom fields must show in the same way according to the number of persons entered. The code should allow for upgrading, so should use the filters/actions provided by woocommerce and be kept to the theme's [login to view URL] file or template files in the theme's /woocommerce folder to override default woocommerce files. If all works well, we plan to develop the code further with the successful candidate to publish it as a woocommerce extension/plugin (further work is available) ======================================================= So basically, Client need the following fields to show up depending on how many 'persons' are selected: [login to view URL] If 2 people are select on this page: [login to view URL] then there would be two rows of the fields shown on this page: [login to view URL] We need to be able to specify which products this will happen on, and also be able to add/edit the fields to include changing the field name, data type (text/text area/dropdown/checkbox etc) We also use Gravity Forms which we have the Woocommerce/Gravity plugin which may be useful in this project. I don't mind whether existing plugins are adapted. Read every thing in detail and reply soon..
