The addRule() method is used in conjunction with the $filter->addField() method to define the filters to apply to a specific field. The filters in this example strip HTML tags, trim whitespace, and convert the text to uppercase. Finally, the $filter->filter() method is used to apply the filters to the form data. Overall, the addRule() function is used in conjunction with various package libraries to validate and/or filter form data.
