Ok, this is real rough, but it gets the job done. This mod allows you to order items that you have 0 stock of, to allow people to back-order your products.
This is pretty untested, but it works good so far from my testing of ordering and deleting products a few times.
Like i said, its really rough, because if the person orders 5 of one type product that IS in stock, then goes back and adds 5 more to the order, the checkout window will just say 10 items, it won't differentiate between there being 5 in stock and 5 not that will be back ordered.
I'd also like to give credit to Mike Everland, from this thread:
http://forum.x-cart.com/viewtopic.php?t=109&postdays=0&postorder=asc&highl ight=stock&start=0
I basically took what he had and modified it a bit, specifically to make it work with 4.0.17.
This is for X-Cart 4.0.17... if it works for other versions, I have no clue.
Enjoy and please DO improve upon this, x-cart needs a better back ordering system!!!!!!!
