As a rule of thumb, you should never trust the data received from end users and should always validate it before putting it to good use.Before going out and learning a full fledged framework I'm trying to understand the MVC pattern coding basic stuff, at the moment I'm testing with MVC applied to form validation.
This should be done by overriding the yii\base\Model::rules() method.
The following example shows how the validation rules for the Most validators have default error messages that will be added to the model being validated when its attributes fail the validation.
We’ll connect the dots a bit when we work on actually updating todos in our database, so don’t worry if that wasn’t all crystal clear. After you’ve added the code to display the checkboxes, log into php My Admin and manually change the values of a few of the todos in your database.
Then refresh the todos index page in your browser and make sure that the checkboxes on your page are checked/unchecked accordingly, based on their assigned attribute values because that’s how they’re accessed in the server-side code? In CI, you can access submitted form values using CI’s built-in input class.

Alter the application/config/configuration file to autoload the form helper, as shown: We’ll be using checkboxes in order to designate whether or not a todo item has been completed.
CI’s form helper provides us with a bunch of useful functions, including a whole set for rendering different form inputs — text inputs, dropdowns, radio buttons, etc.
annotation is necessary for this new constraint in order to make it available for use in classes via annotations.
Options for your constraint are represented as public properties on the constraint class.
In order to render our form’s elements, we’ll use CI’s form helper.
