Member Function Documentation

◆ actual_number_of_questions()

question_type::actual_number_of_questions ( $question )

inherited

Returns the number of question numbers which are used by the question.

This function returns the number of question numbers to be assigned to the question. Most question types will have length one; they will be assigned one number. The 'description' type, however does not use up a number and so has a length of zero. Other question types may wish to handle a bundle of questions and hence return a number greater than one.

Return values

int	The number of question numbers which should be assigned to the question.

Parameters

object $question The question whose length is to be determined. Question type specific information is included.

Reimplemented in qtype_description.

◆ break_down_stats_and_response_analysis_by_variant()

question_type::break_down_stats_and_response_analysis_by_variant ( $questiondata )

inherited

Whether or not to break down question stats and response analysis, for a question defined by $questiondata.

Parameters

object $questiondata The full question definition data.

Return values

bool

◆ can_analyse_responses()

question_type::can_analyse_responses ( )

inherited

Whether this question type can perform a frequency analysis of student responses.

If this method returns true, you must implement the get_possible_responses method, and the question_definition class must implement the classify_response method.

Return values

bool	whether this report can analyse all the student responses for things like the quiz statistics report.

Reimplemented in qtype_randomsamatch, qtype_multianswer, qtype_missingtype, and qtype_description.

◆ choice_options_to_feedback()

qtype_gapselect::choice_options_to_feedback ( $choice )

protected

Choices are stored in the question_answers table, and any options need to be put into the feedback field somehow.

This method is responsible for converting all the options to a single string for this purpose. It is used by save_question_options().

Parameters

array $choice the form data relating to this choice.

Return values

string ready to store in the database.

		$extraanswerfields
	)

protectedinherited

Return $answerextra, filling necessary fields for the extra answer fields table.

The questions may want to overload it to save files or do other data processing.

◆ finished_edit_wizard()

question_type::finished_edit_wizard ( $form )

inherited

Returns true if the editing wizard is finished, false otherwise.

The default implementation returns true, which is suitable for all question- types that only use one editing form. This function is used in question.php to decide whether we can regrade any states of the edited question and redirect to edit.php.

The dataset dependent question-type, which is extended by the calculated question-type, overwrites this method because it uses multiple pages (i.e. a wizard) to set up the question and associated datasets.

Parameters

object $form The data submitted by the previous page.

Return values

bool	Whether the wizard's last page was submitted or not.

Reimplemented in qtype_calculatedsimple, and qtype_calculated.

◆ generate_test()

question_type::generate_test	(	$name,
		$courseid = `null`

array of groups

◆ get_extra_question_bank_actions()

question_type::get_extra_question_bank_actions ( stdClass $question )

inherited

Get extra actions for a question of this type to add to the question bank edit menu.

This method is called if the edit_menu_column is being used in the question bank, which it is by default since Moodle 3.8. If applicable for your question type, you can return arn array of . These will be added at the end of the Edit menu for this question. The $question object passed in will have a hard-to-predict set of fields, because the fields present depend on which columns are included in the question bank view. However, you can rely on 'id', 'createdby', 'contextid', 'hidden' and 'category' (id) being present, and so you can call question_has_capability_on without causing performance problems. stdClass $question the available information about the particular question the action is for. action_menu_link[] any actions you want to add to the Edit menu for this question.

◆ get_heading()

question_type::get_heading ( $adding = false )

inherited

Method called by display_question_editing_page and by question.php to get heading for breadcrumbs.

Return values

string the heading

◆ get_possible_responses()

qtype_gapselect_base::get_possible_responses ( $questiondata )

inherited

This method should return all the possible types of response that are recognised for this question.

The question is modelled as comprising one or more subparts. For each subpart, there are one or more classes that that students response might fall into, each of those classes earning a certain score.

For example, in a shortanswer question, there is only one subpart, the text entry field. The response the student gave will be classified according to which of the possible $question->options->answers it matches.

For the matching question type, there will be one subpart for each question stem, and for each stem, each of the possible choices is a class of student's response.

A response is an object with two fields, ->responseclass is a string presentation of that response, and ->fraction, the credit for a response in that class.

Array keys have no specific meaning, but must be unique, and must be the same if this function is called repeatedly.

Parameters

object $question the question definition data.

Return values

array keys are subquestionid, values are arrays of possible responses to that subquestion.

Reimplemented from question_type.

◆ get_question_options()

qtype_gapselect_base::get_question_options ( $question )

inherited

Loads the question type specific options for the question.

This function loads any question type specific options for the question from the database into the question object. This information is placed in the $question->options field. A question type is free, however, to decide on a internal structure of the options field.

Return values

bool	Indicates success or failure.

Parameters

object $question The question object for the question. This object should be updated to include the question type specific information (it is passed by reference).

Reimplemented from question_type.

◆ get_random_guess_score()

qtype_gapselect_base::get_random_guess_score ( $questiondata )

inherited

Calculate the score a monkey would get on a question by clicking randomly.

Some question types have significant non-zero average expected score of the response is just selected randomly. For example 50% for a true-false question. It is useful to know what this is. For example it gets shown in the quiz statistics report.

For almost any open-ended question type (E.g. shortanswer or numerical) this should be 0.

For selective response question types (e.g. multiple choice), you can probably compute this.

For particularly complicated question types the may be impossible or very difficult to compute. In this case return null. (Or, if the expected score is very tiny even though the exact value is unknown, it may appropriate to return 0.)

Parameters

stdClass $questiondata data defining a question, as returned by question_bank::load_question_data().

Return values

number|null either a fraction estimating what the student would score by guessing, or null, if it is not possible to estimate.

Reimplemented from question_type.

inherited

Saves (creates or updates) a question.

Given some question info and some data about the answers this function parses, organises and saves the question It is used by } when saving new data from * a form, and also by import.php when importing questions This function in turn calls save_question_options to save question-type specific data.

Whether we are saving a new question or updating an existing one can be determined by testing !empty($question->id). If it is not empty, we are updating.

The question will be saved in category $form->category.

Parameters

object	$question	the question object which should be updated. For a new question will be mostly empty.
object	$form	the object containing the information to save, as if from the question editing form.
object	$course	not really used any more.

Return values

object On success, return the new question object. On failure, return an object as follows. If the error object has an errors field, display that as an error message. Otherwise, the editing form will be redisplayed with validation errors, from validation_errors field, which is itself an object, shown next to the form fields. (I don't think this is accurate any more.)
