Ubercart

Hi Venkat / Ryan,

I have a similar issue , Can I have a product which is a mixture of already existing products. For eg In order to build a PC i will need to add a motherboard , processor ,etc... now I already have Processor and motherboard as separate products , how do I create a view for the user where the user can select processor and motherboard according to his choice.

Thanks

call the function

uc_cart_add_item($nid, $qty = 1, $data = NULL, $cid = NULL, $msg = TRUE, $check_redirect = TRUE);

$data is an arbitrary array of key => value data that will be stored in uc_order_products table. (Usually this will be a module_invoke_all('add_to_cart_data', $form_values), where form values contains the data that would be in an add to cart form.)

$cid is a cart id (leave it null for current user)

$msg is whether or not to show a message saying that the product has been added to the cart.

$check_redirect is whether or not to redirect the user afterwards (make if false if you need to add a number of items, or don't want the user redirected)

Not directly, hook_add_to_cart() is mostly for letting Ubercart know "Yes you can add that item to the cart." or "No you can't add that and here's what to tell the customer."

You could perhaps call uc_cart_add_item() to add another item and
return array('success' => FALSE, 'silent' => TRUE); to prevent adding the one that the customer was trying to add. (That has the potential for infinite recursion bugs, so code carefully.)

There's another hook in that flow that may be useful: hook_add_to_cart_data($form_values), called just before hook_add_to_cart(). You cannot modify the $form_values being passed in, and should return the array that becomes the $data argument for hook_add_to_cart(). (That one is defined in docs/hooks.php)

Hope that helps.
