The Validator uses the Validation rules and has 3 additional validation rules built in, required, optional, and present.

These rules should be called first, and for required and present, if they fail no further validation rules will run.

• required: this means the key must be present and the value is notEmpty
• optional: this means that data is optional, if the value is empty then it will not run any more validation rules.
• present: this means that the data array must have the key present, its irrelevant if the value is empty or not.
