PHP Drag and Drop Shopping Cart by Ajax jQuery



Hi friends in this post we are going to develop product drag and drop PHP shopping cart by using Jquery with Ajax by using drag and drop event without page refresh. Here I will fetch product from database and display on webpage and user can add that product to shopping cart by using simple drag and drop product to the cart and adding product to cart and all product details are stored in session variable. This all process done without page refresh. If buyer do not want to buy any of the shopping cart product then he can also removed that product from shopping cart this is done by clear this session of that item from the cart and item will be removed from the shopping cart without page refresh event. This is an advance shopping cart in which I have only use php jquery Ajax with mysql database, if you are looking to learn drag and drop product shopping cart by using PHP with Jquery Ajax. In this shopping cart user can add product to shopping cart by drag and drop item to product drag area division and below item which we have added to our cart with details like item name quantity price, if you already add item to cart, again you cannot add item to cart, you can also remove item from this shopping cart.
