You have expertise in Codeigniter 3, so sounds good, but what about the future of the Codeigniter? Yes, I am talking about Codeigniter 4. The registration system is part of every application because you can track your user’s activity using some information once your user logged in to your system.

Creating the registration process in Codeigniter 4 is difficult because they have changed many things in the Codeigniter version 4. They have introduced new session methods, and they have also entered the latest techniques/methods in the form validation class/library. However, the point is, how can you use the new libraries in Codeigniter 4.

The series is going to explain each and everything from scratch. You guys can easily understand the signup/registration process basics, and we also have some auth system in Codeigniter.

But while I am creating this series, the version is not stable, so we can’t use it in this series, but we can consider it later.

We give you an overview of the session because we will use the session library in Codeigniter 4.

We discuss the form helper in Codeigniter 4, so you can create the forms by using the form helper in ci; once you create structure, then we discuss the form validation library in Codeigniter 4.

Before starting this series, I consider that you have the basic knowledge of MVC (Model View Controller) and the PHP with MySQL. OOP in PHP are the prerequisite courses; you have to familiar with CI 4 before starting the lesson.
