how to display validation errors inside the controller of codeigniter?

Question

I have basic codeigniter mvc structure where my form data comes into controller and checks for the validations. i am writing an API to give back the data or to display the errors. what function should i use to get the validation errors in the controller?

Answer 1

$this->validator->getErrors();

This line will give you errors in the JSON format.

Example:

{ "mobile_no": "The mobile_no field is required." }
