Cart Data Storage

This source code takes advantage of PHP SESSIONS, PHP COOKIES, and MySQL when storing cart data.

  • We use PHP COOKIES to save the site visitor’s user_id locally.
  • We use PHP SESSIONS as back up just in case cookies are disabled in the user’s browser.
  • We use MySQL to store cart items in the database.
  • This way, cart items can be resurrected even if the user closed his browser, logged out or logged in another computer.

Here’s the logic:

IF cookies are enabled, AND if user is logged in, we save ‘session user_id’ to ‘user_id variable’. The value of ‘user_id variable’ is very important because we use it to save ‘user_id’ both in PHP ‘cookie’ and ‘session’.

IF cookies are enabled, AND if user is not logged in, AND if user already have a ‘cookie user_id’ token, we save ‘cookie user_id’ to ‘user_id variable’.

IF cookies are enabled, AND if user is not logged in, AND if ‘cookie user_id’ is not set (it means, visitor never used the cart before), we get new token as ‘user_id variable’ value.

IF cookies are enabled, AND user is logged in OR not logged in, we set ‘cookie user_id’ and ‘session user_id’ with the final ‘user_id variable’ value. This will retrieve the cart data with the same ‘user_id’ from MySQL database.

IF cookies are disabled, AND user is logged in, we maintain ‘session user_id’.

IF cookies are disabled, AND user is not logged in, we get new token and save it to ‘session user_id’.

Important Note: The statements above can be understood more clearly if you will see the code implementation on /config/core.php line 26 onwards.

Database Design

Our database name will be “shop_cart_complete”, and we will have twelve (12) tables.

Simple Set Up

You can run this source code successfully with few easy steps.

10.1 Run the Home Page

I assume you are installing this source code on localhost. In my case, I installed this code in this directory:

The reason for these multiple folders is because I have many projects and I need to organize them this way. I can access the system in this URL: http://localhost/CodeOfaNinja/SourceCodes/Systems/ShoppingCartSystem/

You will see an error, that’s why we need to do the following steps.

1. In your PhpMyAdmin, create a database with the name “shopping_cart_system”.

2. Import the “shopping_cart_system.sql” SQL file from the “dev” folder.

3. Change rewrite base directory in line 7 of the .htaccess file.

RewriteBase RewriteBase /CodeOfaNinja/SourceCodes/Systems/ShoppingCartSystem/

4. Configure $home_url in line 72 of /config/core.php

$home_url = "http://localhost/CodeOfaNinja/SourceCodes/Systems/ShoppingCartSystem/";

5. Configure database in /config/database.php, example settings would look like:

// specify your own database credentials
private $host = "localhost";
private $db_name = "shopping_cart_system";
private $username = "root";
private $password = "";
public $conn;

6. Try to log in by running the login page.


Use the following login credentials.

Admin Section Login
Username: [email protected]
Password: [email protected]

Customer Account Login
Username: [email protected]
Password: [email protected]

3. How To Disable Sandbox Mode?

This source code is in sandbox mode by default, it means any PayPal transactions are for testing purposes only. To disable the PayPal Sandbox mode:

Open /libs/php/paypal_checkout.php

Change line 51, from

$form='<form id="paypal_checkout" action="" method="post">';


$form='<form id="paypal_checkout" action="" method="post">';

Change the email address (line 5) to your real PayPal account email address. Payment will be sent to the specified PayPal account.

How To Make TinyMCE File Manager / File Browser Work?

1. Change line 71 of /libs/js/responsive_filemanager/filemanager/config/config.php

'upload_dir' => '/YOUR_ROOT_DIRECTORY/libs/js/responsive_filemanager/source/',

2. Change line 42-43 of /admin/layout_foot.php

external_plugins: { "filemanager" : "/YOUR_ROOT_DIRECTORY/libs/js/responsive_filemanager/filemanager/plugin.min.js"},

Some More Notes

1. This system works with PHP 5.5+

2. Rewrite module must be enable in your apache server (this is enabled by default in most web servers and localhost)
