function uc_wishlist_form_alter in UC Wish List 8

Same name and namespace in other branches

1. 6 uc_wishlist.module \uc_wishlist_form_alter()
2. 7 uc_wishlist.module \uc_wishlist_form_alter()

Implements hook_form_alter().

Alter uc_product_add_to_cart_form instances to include 'add to wish list' button. Form submission is routed through uc_wishlist_add_to_wishlist to differentiate between 'add to cart' and 'add to wish list'. If this module is added to Ubercart core, then this can be simplified.

Alter uc_cart_checkout_form to include by default the delivery address of a wish list's owner, if items come from a single wish list.

File

./uc_wishlist.module, line 55

Allows users to create public shopping/wish lists.
