Custom page after add to cart (Catgory dependant)

Hi,

This is what I am wanting to do:

My shop has the following setup:

Category 1 (5 Sub Categories > each with 5 items)
Category 2 (5 items)
Category 3 (5 items)

All items in Category 1 can be purchased individually but also require products from Category 2
All items in Category 2 can be purchased individually but also require products from Category 3

What I want to do is, if someone buys any of the products in Category 1, once they add to cart, they are redirected to a page (customer) that asks if they need Category 2 products.
If Yes, they go to category 2, if no, they go to checkout.(and same through the Category 2)

Basically, once they have added the main product, I want to direct them to the custom page. (I read the post relating to add to cart HTML button , but not sure if that is what I am looking for as I just want to use the standard checkout button.

Do I have to set up custom check buts for every product?

Regards

Simon B

Hi Nicolas,

Thanks for the quick reply (as always)

I have looked over what you say, and the link, and the file, but no idea how to do. (any chance of getting an outline, start etc on the coding - not my forte)

EDIT:

Staring at the screen, I think what I am trying to do may be more extremely complicated so I think there may be an easier approach....

Edit the 'Continue Shopping' so it goes to a custom page (whereby I can direct with instructions from there)

Off to find out how I can do that.

Ok... from anothe post here:

<?php echo $this->cartClass->displayButton(JText::_('CUSTOM MESSAGE'),'continue_shopping',$this->params,'','window.top.location.href=\'PAGE TO DIRECT TO'; return false;','id="hikashop_add_to_cart_continue_button"');?>

In the file "notice" of the "checkout" view in Display->views.

A good start and I can live with that for a while.
