PHP Shopping Cart | Add to Cart Feature In PHP & MySQL

Today I going to share the PHP shopping cart program. In other words, add to cart feature in PHP and MySQL. You had seen add to cart feature in very big and well-known e-commerce platform like Amazon, Flipkart, etc. Basically, the cart button creates a list of products, that you want to buy. Cart program is full of calculation in the backend.

Today I am sharing a simple PHP shopping cart program example and source code. After visit this post, you will able to create add to cart feature in PHP & MySQL. This program is very simple, but it looks pretty good. Because of this program’s structure is built-in bootstrap. I used bootstrap for an attractive and responsive look.

In this add to cart program, I did not use the separate CSS file, I put some in-line CSS. So, There is Just one file and folder for store images. MySQL fetches images from the image folder. One thing I want to explain: MySQL doesn’t store images in the database, SQL store only image name in the database. That’s why you have to create a folder to store images.

Preview Of This Add To Cart Program

First, see this preview of the program. If you like, then to go for source code.

So, this is the preview. I think this program looks not bad. For beginners, this program will be very informative. Because If you do search for this program most of will in any PHP framework. That will be difficult to understand. Now time to share code.

PHP Shopping Cart Programs Source Code

As always, Before sharing source code I want to say about this program. For this program, I used PHP, MySQL, and Bootstrap. create a database is very important, without the database this program is a dummy. MySQL create this program dynamic. In the database, we will store the product name, ID, product price, & product image path.

You have to do 3 things: Create a database named ‘cart‘, create an ‘index.php‘ file, and the final thing create a folder and store product images.

Create Images Folder

Create a folder named ‘images‘ and put all your products images there. This is a very important thing in this program. And rename all images with simple names like ‘1jpg’ or ‘product1.jpg’. because of these types of simple names is easy to put in MySQL database. Otherwise, if your images have a long name that’s will be difficult to remember names, then you have to copy and paste names.

Create Database

Create a database named ‘cart’ because in MySQL connection I had put database name cart. If you create a database with another name you also have to change the database name in PHP file. After successfully creating database go to SQL command section and put these codes given below.

CREATE TABLE `tbl_product` (
  `id` int(11) NOT NULL,
  `name` varchar(255) NOT NULL,
  `image` varchar(255) NOT NULL,
  `price` double(10,2) NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

CREATE TABLE `tbl_product` (

`id` int(11) NOT NULL,

`name` varchar(255) NOT NULL,

`image` varchar(255) NOT NULL,

`price` double(10,2) NOT NULL

) ENGINE=MyISAM DEFAULT CHARSET=latin1;

This code will create a table with required fields. Now you can insert new products in your database. For add products, go to your database located in PhpMyAdmin, and go to insert section. Now there you can add products by giving their products info like ID, name, price & image name.

Create PHP File

Now you have to create a PHP file named ‘index.php’ or any name for giving life to this program. After creating file put these codes given here below.

<?php 
/* code by webdevtrick ( https://webdevtrick.com ) */
session_start();
$connect = mysqli_connect("localhost", "root", "", "cart");

if(isset($_POST["add_to_cart"]))
{
	if(isset($_SESSION["shopping_cart"]))
	{
		$item_array_id = array_column($_SESSION["shopping_cart"], "item_id");
		if(!in_array($_GET["id"], $item_array_id))
		{
			$count = count($_SESSION["shopping_cart"]);
			$item_array = array(
				'item_id'			=>	$_GET["id"],
				'item_name'			=>	$_POST["hidden_name"],
				'item_price'		=>	$_POST["hidden_price"],
				'item_quantity'		=>	$_POST["quantity"]
			);
			$_SESSION["shopping_cart"][$count] = $item_array;
		}
		else
		{
			echo '<script>alert("Item Already Added")</script>';
		}
	}
	else
	{
		$item_array = array(
			'item_id'			=>	$_GET["id"],
			'item_name'			=>	$_POST["hidden_name"],
			'item_price'		=>	$_POST["hidden_price"],
			'item_quantity'		=>	$_POST["quantity"]
		);
		$_SESSION["shopping_cart"][0] = $item_array;
	}
}

if(isset($_GET["action"]))
{
	if($_GET["action"] == "delete")
	{
		foreach($_SESSION["shopping_cart"] as $keys => $values)
		{
			if($values["item_id"] == $_GET["id"])
			{
				unset($_SESSION["shopping_cart"][$keys]);
				echo '<script>alert("Item Removed")</script>';
				echo '<script>window.location="index.php"</script>';
			}
		}
	}
}

Its good that you shared the source code. Some people would charge for that also. But beginners like us, know the value of this code when shared for free. And we are grateful for that.

I get an issue: I add some items to my cart. I then delete of of those addede items. It updates the cart correctly. BUT – if I try to add another/a new item to the cart it doesn’t get added correctly – in stead it replaces one of the original items in the cart?! Does anyone experience the same – and have a fix? Highly appreciated!
