How does CI organise the application?
When you download a CI package from the site and extract in the root of your application folder you will find a folder
Codeigniter ->System->application
This application folder should only be modified while the application is built.
What CI does is it splits the application into several pieces as follows:
- Models
- Views
- Controllers
What do these pieces contain?
- Models: The Models folder contains only those files that involve database operations such as INSERT, UPDATE, SELECT, DELETE, DROP etc.
- Views: The Views folder contains only those files that are going to be viewed by the application user
- Controllers: The Controllers folder contain only those files that process the data entered in some page(from views folder)
In this manner CI provides a proper structure for the application.
Where are the CI library features?
The CI library is more commonly known as “helpers”.Click here for documentation on “helpers”.
