In this video on the CodeIgniter 4 framework, I show you how to create validation rules for a “model”, thus enabling the data to go through a check before being inserted (insert) or updated (update).
The way to validate the data is simple, just insert an attribute (in array format) in the model class and in each position of the array you define the rules for each field.

CI4 provides several validation methods, and you can check them all through the link: https://codeigniter4.github.io/userguide/libraries/validation.html?highlight=validation#available-rules
