	)

inherited

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

int	$originalValue	The original general state of the checkboxes before the user first clicks this element

◆ add_per_answer_fields()

question_edit_form::add_per_answer_fields	(	&	$mform,
			$label,
			$gradeoptions,
			$minoptions = `QUESTION_NUMANS_START`,
			$addoptions = `QUESTION_NUMANS_ADD`
	)

protected

Add a set of form fields, obtained from get_per_answer_fields, to the form, one for each existing answer, with some blanks for some new ones.

Parameters

object	$mform	the form being built.
	$label	the label to use for each option.

◆ add_tag_fields()

question_edit_form::add_tag_fields ( $mform )

protected

Add the tag and course tag fields to the mform.

If the form is being built in a course context then add the field for course tags.

If the question category doesn't belong to a course context or we aren't editing in a course context then add the tags element to allow tags to be added to the question category context.

Parameters

object $mform The form being built

◆ after_definition()

moodleform::after_definition ( )

protectedinherited

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.

void

◆ validate_defined_fields()

moodleform::validate_defined_fields ( $validateonnosubmit = false )

inherited

Validate the form.

You almost always want to call } 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,

Parameters

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

Return values

bool	true if form data valid

protectedinherited

		$files

Server side rules do not work for uploaded files, implement serverside rules here if needed.

array	$files	array of uploaded files "element_name"=>tmp_file_path
