Lesson 27 - E-shop in PHP - Shopping cart

In the previous lesson, E-shop in PHP - Test data, we added 100 test products to our e-shop. The next couple of tutorials will be about creating orders, i.e. adding goods to a cart and passing them through the checkout.

Shopping cart

Users add products to a cart, then, when they're done, they proceed to checkout and finish the order. This functionality is done in different ways in different e-shops, either on server-side or client-side. Let's introduce all of the possible approaches, their advantages, drawbacks, and then decide which one to use.

They have the following benefits:

  • They are widely supported by browsers
  • They are persistent (it doesn't happen that the data expires after a short time)

And these disadvantages:

  • Size limitation to 4096 bytes
  • Data is sent to the server with each request, which is not a disadvantage, but it does not make much sense in our case

Local storage
