Using Codeigniter as RestAPI (using Axios)

Reading the documentation, $this->validate() will validate the input data based on the request type. So if you have a GET request, it will validate the $_GET data. If you have a POST (or PUT?) request, it will validate the $_POST data.

This seems to happen transparently. You simply use the $this->validate() call as a gateway to control the flow. You don't need to see the data at this point, only set up your validation rules that must pass.

The boolean logic would be:

• If validation passes, do something.
  
• If validation fails, do something else.
  

If you need access to the request data after the validation runs, you can call $this->request->getPost(), for example.
