I update the QTY based on
case_size of a product. I've made an observer to do that. If the
case_size is 144 and a customer buys two cases then QTY will automatically become 288PCS. When the customer clicks the Edit button then the product QTY on the add to cart page goes back to 2 case. Everything is working good, but when a customer edits the QTY see (image) then everything goes wrong of course!!
I want to remove the UPDATE button and make the QTY input readonly but until now no luck.
app\design\frontend\base\default\template\checkout\cart.phtml but it works on the
magento/checkout/cart/configure page not on
magento/checkout/cart/ (see image)
Any tips would be highly appreciated.
Thank you all
