Contribute to CodeIgniter

There are many ways to contribute to the CodeIgniter project, whether you are a developer or not.

CodeIgniter is a community driven project and accepts contributions of code and documentation from the community. These contributions are made in the form of Issues or Pull Requests on the CodeIgniter repository on GitHub.

Issues are a quick way to point out a bug. If you find a bug or documentation error in CodeIgniter then please check a few things first:

  • There is not already an open Issue
  • The issue has already been fixed (check the develop branch, or look for closed Issues)
  • Is it something really obvious that you fix it yourself?
  • If you are unsure if you have found a bug, then start a new thread in the CodeIgniter forum, in the Issues section!

Reporting issues is helpful but an even better approach is to send a Pull Request, which is done by “Forking” the main repository and committing to your own copy. This will require you to use the version control system called Git.

CodeIgniter 4

CodeIgniter 4 has its own Github repository. It deviates enough from CodeIgniter 3 that we want to keep them separate. The CodeIgniter 4 roadmap is explained on our forum, and work to be done is detailed in the repository issues.

Not a Programmer?


We always need feedback on what works and what does not! Most of the development effort is going into Version 3, so that is where the need is greatest. If you find something that is definitely a bug, and you are a Github user, please create a new "issue". If you are not a Github user, or if you are unsure if you have found a bug, then start a new thread in the CodeIgniter forum Issues section!


Every project needs good documentation! The CodeIgniter user guide is part of the Github project (mentioned above), and there is always room for more tutorials.


The word needs to be spread about good and worthy projects, which we think CodeIgniter is :) You can help by being active in the forums, answering questions, and by spreading the word inside your developer or user community.


The forum can always use moderators, to make sure that discussions/threads stay on topic, and to weed out the inappropriate users or comments!


Suggestions and help with our website, User Guide, and forum design are always welcome! We are working on themes for each of these, which will be shared in their own Github repository.

Are You a Programmer?


If you would like to get involved in helping to build the next version of CodeIgniter, join us on Github! A detailed contribution guide is in the User Guide, but the main points are to make sure your code conforms to our style guide, that it is properly documented, and that you use the Git-Flow branching model.


Every project needs a core group of developers, familiar with the project standards and conventions, to review proposed enhancements and fixes. We have been really fortunate with our group of reviewers so far, and hope to recruit a few more. Reviewers also have "commit" privileges for the code repository.

Do You see the Big Picture?

Wise Men

The direction that CodeIgniter takes, and hence its roadmap, needs to be carefully vetted and wisely chosen. We have a small group from the community, devoted to the framework, to form a council for discussing and choosing the future direction(s) of the framework!

Part of our job over the next year will be to put in place proper governance procedures.

I'm an Academic (Note from the project lead...)

Part of my goal is to build a "living lab" around this project, teaching my students how to work on open source projects, and having them help make this the best one ever!

I welcome collaboration, on any level, with other academics. This could be in the form of sharing teaching materials, working on this or your open source project, or even just sharing experiences.
