Asked by PranjalShah in PHP Scripting Language, Miscellaneous Web Development
In the code below I am populating results based on the search criteria. As you can see there is a checkbox in front of each item..Now I want to do something like a shopping cart where a user can select an item and it pops up a box in which the item is listed with the quantity and its price ...he should be able to configure the quantity and the price should be updated accordingly...user can select multiple items from the list... the shopping bag should be on the right side of the same page..I dont have to do all the till the checkout process but the shopping cart should be exported as an excel file to save on a local system...
