View Demo PHP Shopping Cart Software Development OverviewPHP shopping cart example has the following functionality:
I have retrieved information like name, code, price, and photos from the database. The resultant information is in an array format. I have iterated this resultant array to form the product gallery. Every product in the gallery will have an add-to-cart option. I have used the PHP shopping cart session to store and manage the items in the cart. Once the session expires, the cart items get cleared. This code has an option to clear the entire cart or to remove any particular item from the cart. File Structure The shopping cart software example has the following file structure. The below list has the file names and their responsibility. You can build a gallery-based shopping cart software with these files in few minutes.
Create a Product Gallery for Shopping CartIf you are familiar with online shopping, you might have across product galleries. It is an important gateway in a shopping cart application. Users will use the product gallery to get a feel of the products available to buy. It is a critical component of every online store. You should always provide a catalog of the available products to let them have a glance. It helps to promote your products to impulsive buyers. In the following code, I have shown the PHP script to get the product results from the database. The result will be an array and iterated to create a product card in each iteration. The DBController.php class will handle the DAO operation and fetch products result.
Adding Products to Shopping CartAfter creating the product gallery page, we need to work on the PHP code to perform the cart actions. They are add-to-cart, remove a single item from the cart, clear the complete cart and similar. In the above code, I have added the HTML option to add the product to the shopping cart from the product gallery. When the user clicks the ‘Add to Cart’ button, the HTML form passes the product id to the backend PHP script. In PHP, I receive and process the cart action with a switch control statement. I have created PHP switch cases to handle the add-to-cart, remove-single, empty-cart actions. The action is the argument to the switch statement. Then it executes the corresponding action case as requested. The “add” case handles the add to cart action. In this case, I have received the product id and the quantity. The cart session stores the submitted product. I have updated the quantity of the product if it already exists in the session cart. The PHP session index is the reference to perform this action.
List Cart Items from the PHP SessionThis code shows the HTML to display the shopping cart with action controls. The loop iterates the cart session to list the cart items in a tabular format. Each row shows the product image, title, price, item quantity with a remove option. Also, it shows the total item quantity and the total item price by summing up the individual cart items.
Removing or Clearing Cart ItemThe loop iterates the cart session array to display the cart items. Each cart item will have a remove link. If the shopping cart user clicks the remove link then, I remove the respective cart item from the session. I have provided an ‘Empty Cart’ button control above the shopping cart. The users can use it to completely wipe out the cart session and clear the cart. I have presented the PHP code below to “remove” and the “empty” cases. They handle the shopping cart to remove/clear actions. I have used PHP unset() to clear the cart session to delete the added item from the shopping cart.
Database Product Table for Shopping CartYou should import the following SQL script. It will create the product table and load data into it. In the example, I have used this product data to display products in the gallery.
