I've been searching but surprisingly can't seem to get anywhere with this. I'd like to get "quantity box" in the "Featured Products" of the front page of my site (for entering the desired amount of products). I would also need a "add to cart" button and I would like a "more details" button too. I can't find an addin or code snippet anywhere to make this happen.

Any suggestion on how to do this? Is this even possible with Zen Cart?

I recently migrated over from oscommerce. If an "add to cart" button was on a page in oscommerce (for example, on the home page in the featured products section) this code would insert a quantity field:

Code:
$button = '<form name="cart_add" method="post" action="' . tep_href_link(FILENAME_PRODUCT_INFO, tep_get_all_get_params(array('action')) . 'action=update_product&products_id=' . $products['products_id'] , 'NONSSL'). '"><input type="hidden" name="products_id" value="' . $products['products_id'] . '"><input type="text" name="cart_quantity" value="1" maxlength="5" size="5"><br>' . tep_image_submit('button_in_cart.gif', IMAGE_BUTTON_IN_CART) . '</form>';
Anything like this available for Zen Cart? Thanks for any suggestions.
