The definition of a question of a particular type.
This class is a close match to the question table in the database. Definitions of question of a particular type normally subclass one of the more specific classes question_with_responses, question_graded_automatically or question_information_item.

When an in-progress question_attempt is re-loaded from the database, this method is called so that the question can re-initialise its internal state as needed by this attempt.
For example, the multiple choice question type needs to set the order of the choices to the order that was set up when start_attempt was called originally. All the information required to do this should be in the $step object, which is the first step of the question_attempt being loaded.
- Parameters
-
Reimplemented in qtype_calculated_question, qtype_calculatedmulti_multi_question, qtype_calculatedmulti_single_question, qtype_gapselect_question_base, qtype_match_question, qtype_multianswer_question, qtype_multichoice_base, qtype_numerical_question, qtype_ordering_question, and qtype_randomsamatch_question.
Return the question settings that define this question as structured data.
This is used by external systems such as the Moodle mobile app, which want to display the question themselves, rather than using the renderer provided.
This method should only return the data that the student is allowed to see or know, given the current state of the question. For example, do not include the 'General feedback' until the student has completed the question, and even then, only include it if the question_display_options say it should be visible.
But, within those rules, it is recommended that you return all the settings for the question, to give maximum flexibility to the external system providing its own rendering of the question.
- Parameters
-
- Return values
-
| mixed | structure representing the question settings. In web services, this will be JSON-encoded. |
Reimplemented in qtype_essay_question, qtype_gapselect_question_base, qtype_match_question, qtype_multianswer_question, qtype_multichoice_base, qtype_numerical_question, qtype_shortanswer_question, and qtype_truefalse_question.

( |
| ) |
|
| question_definition::get_student_response_values_for_simulation |
( |
| $realresponse | ) |
|
Does the opposite of prepare_simulated_post_data.
This takes a student response (the POST values returned from the HTML form that takes the student response during a student attempt) it then represents it in a way that is understandable by a human.
Primarily this is used when creating a file of csv from real student responses in order later to be able to simulate the same student interaction with a quiz later.
- Parameters
-
| string[] | $realresponse | the response array as was returned from the form during a student attempt (without prefixes). |
- Return values
-
| string[] | an array of data representing a student response. |
Reimplemented in qtype_match_question, qtype_multianswer_question, qtype_multichoice_multi_question, and qtype_multichoice_single_question.
| question_definition::make_behaviour |
( |
question_attempt | $qa, |
|
|
| $preferredbehaviour ) |
Creat the appropriate behaviour for an attempt at this quetsion, given the desired (archetypal) behaviour.
This default implementation will suit most normal graded questions.
If your question is of a patricular type, then it may need to do something different. For example, if your question can only be graded manually, then it should probably return a manualgraded behaviour, irrespective of what is asked for.
If your question wants to do somthing especially complicated is some situations, then you may wish to return a particular behaviour related to the one asked for. For example, you migth want to return a qbehaviour_interactive_adapted_for_myqtype.
- Parameters
-
| question_attempt | $qa | the attempt we are creating a behaviour for. |
| string | $preferredbehaviour | the requested type of behaviour. |
- Return values
-
Reimplemented in qtype_essay_question, question_graded_automatically_with_countback, and question_information_item.
| question_definition::prepare_simulated_post_data |
( |
| $simulatedresponse | ) |
|
Takes an array of values representing a student response represented in a way that is understandable by a human and transforms that to the response as the POST values returned from the HTML form that takes the student response during a student attempt.
Primarily this is used when reading csv values from a file of student responses in order to be able to simulate the student interaction with a quiz.
In most cases the array will just be returned as is. Some question types will need to transform the keys of the array, as the meaning of the keys in the html form is deliberately obfuscated so that someone looking at the html does not get an advantage. The values that represent the response might also be changed in order to more meaningful to a human.
See the examples of question types that have overridden this in core and also see the csv files of simulated student responses used in unit tests in :
- mod/quiz/tests/fixtures/stepsXX.csv
- mod/quiz/report/responses/tests/fixtures/steps00.csv
- mod/quiz/report/statistics/tests/fixtures/stepsXX.csv
Also see , a quiz report plug in for uploading and downloading student responses as csv files.
- Parameters
-
| array | $simulatedresponse | an array of data representing a student response |
- Return values
-
| array | a response array as would be returned from the html form (but without prefixes) |
Reimplemented in qtype_match_question, qtype_multianswer_question, qtype_multichoice_multi_question, and qtype_multichoice_single_question.
Start a new attempt at this question, storing any information that will be needed later in the step.
This is where the question can do any initialisation required on a per-attempt basis. For example, this is where the multiple choice question type randomly shuffles the choices (if that option is set).
Any information about how the question has been set up for this attempt should be stored in the $step, by calling $step->set_qt_var(...).
- Parameters
-
Reimplemented in qtype_calculated_question, qtype_calculatedmulti_multi_question, qtype_calculatedmulti_single_question, qtype_gapselect_question_base, qtype_match_question, qtype_missingtype_question, qtype_multianswer_question, qtype_multichoice_base, qtype_numerical_question, qtype_ordering_question, and qtype_randomsamatch_question.
Update the data representing the initial state of an attempt another version of this question, to allow for the changes.
What is required is probably most easily understood using an example. Think about multiple choice questions. The first step has a variable '_order' which is a comma-separated list of question_answer ids. A different version of the question will have different question_answers with different ids. However, the list of choices should be similar, and so we need to shuffle the new list of ids in the same way that the old one was.
Note: be sure to return all the data that was originally in $oldstep, while updating the fields that require it. Otherwise you might break features like 'Each attempt builds on last' in the quiz.
This method should only be called if {

- validate_can_regrade_with_other_version()} did not flag up a potential problem. So, this method will throw a {
-
coding_exception} if it is not possible to work out a return value.
