Use this method to a cancel and submit button to the end of your form.

After definition hook.
This is useful for intermediate classes to inject logic after the definition was provided without requiring developers to call the parent self::definition()} as it's not obvious by design. The 'intermediate' class is 'MyClass extends IntermediateClass extends moodleform'.
Classes overriding this method should always call the parent. We may not add anything specifically in this instance of the method, but intermediate classes are likely to do so, and so it is a good practice to always call the parent.

Used by tests to simulate submitted form data submission from the user.
For form fields where no data is submitted the default for that field as set by set_data or setDefault will be passed to get_data.
This method sets $_POST or $_GET and $_FILES with the data supplied. Our unit test code empties all these global arrays after each test.
| array | $simulatedsubmitteddata | An associative array of form values (same format as $_POST). |
| array | $simulatedsubmittedfiles | An associative array of files uploaded (same format as $_FILES). Can be omitted. |
| string | $method | 'post' or 'get', defaults to 'post'. |
| null | $formidentifier | the default is to use the class name for this class but you may need to provide a different value here for some forms that are used more than once on the same page. |

'disabledif' - array containing the disabledIf() arguments after the element name. 'rule' - array containing the addRule arguments after the element name. 'expanded' - whether this section of the form should be expanded by default. (Name be a header element.) 'advanced' - whether this element is hidden by 'Show more ...'. |

Validate the form.
You almost always want to call is_validated instead of this because it calls definition_after_data first, before validating the form, which is what you want in 99% of cases.
This is provided as a separate function for those special cases where you want the form validated before definition_after_data is called for example, to selectively add new elements depending on a no_submit_button press, but only when the form is valid when the no_submit_button is pressed,
| bool | $validateonnosubmit | optional, defaults to false. The default behaviour is NOT to validate the form when a no submit button has been pressed. pass true here to override this behaviour |
| bool | true if form data valid |
|
