Turn off Update Button when maximum quantity is 1

[cochlear]

Thanks Ajeh

The Update button is also used to delete things from the cart ...

Because most items have unchangeable quantity of 1, I imagine customers would intuitively use the delete button to delete an item from cart. The update cart button actually doesn't do anything when I click it.

But I realise the update button is occasionally useful when customers buy a product that has a quantity input box. That's why I can't turn it off in admin.

Would setting the Update Button to only show below the Products in the shopping_cart work?

Yes that's a very smart idea! It took me a while to work out that since the update button is useless for 99% of the products, I might as well place it below the #cartContentsDisplay table rather than next to every single product in the cart. It is much better now, but not perfect. I still have a single update button that is redundant 99% of the time, but not all the time, so I cannot turn it off. This button is very cheeky!

Also, Hide Quantity box might make sense on these Products with Maximum of 1 as well ...

Done that. I've also removed the "max: 1" from product listing page (great tip from you on another thread http://www.zen-cart.com/forum/showthread.php?t=39737), shopping cart page (if anyone wants to know, by commenting out $product['showMinUnits'] in line 69 of tpl_shopping_cart_default), and product info page (I think I did this one in admin).
