Class: question_wizard_form - X-Ref
| add_hidden_fields() X-Ref |
| Add all the hidden form fields used by question/question.php. |
Class: question_edit_form - X-Ref
Form definition base class. This defines the common fields thatall question types need. Question types should define their own
class that inherits from this one, and implements the definition_inner()
method.
| __construct($submiturl, $question, $category, $contexts, $formeditable = true) X-Ref |
| No description |
| get_default_value(string $name, $default) X-Ref |
| Return default value for a given form element either from user_preferences table or $default. To make use of user_preferences in your qtype default settings, you need to replace $mform->setDefault({elementname}, {defaultvalue}); in edit_{qtypename}_form.php with $mform->setDefault({elementname}, $this->get_default_value({elementname}, {defaultvalue})); param: string $name the name of the form field. param: mixed $default default value. return: string|null default value for a given form element. |
| definition() X-Ref |
| Build the form definition. This adds all the form fields that the default question type supports. If your question type does not support all these fields, then you can override this method and remove the ones you don't want with $mform->removeElement(). |
| definition_inner($mform) X-Ref |
| Add any question-type specific form fields. param: object $mform the form being built. |
| definition_after_data() X-Ref |
| Tweak the form with values provided by custom fields in use. |
| can_preview() X-Ref |
| Is the question being edited in a state where it can be previewed? return: bool whether to show the preview link. |
| get_per_answer_fields($mform, $label, $gradeoptions,&$repeatedoptions, &$answersoption) X-Ref |
| Get the list of form elements to repeat, one for each answer. param: object $mform the form being built. param: $label the label to use for each option. param: $gradeoptions the possible grades for each answer. param: $repeatedoptions reference to array of repeated options to fill param: $answersoption reference to return the name of $question->options return: array of form fields. |
| add_tag_fields($mform) X-Ref |
| 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. param: object $mform The form being built |
| add_per_answer_fields(&$mform, $label, $gradeoptions,$minoptions = QUESTION_NUMANS_START, $addoptions = QUESTION_NUMANS_ADD) X-Ref |
| 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. param: object $mform the form being built. param: $label the label to use for each option. param: $gradeoptions the possible grades for each answer. param: $minoptions the minimum number of answer blanks to display. param: $addoptions the number of answer blanks to add. Default QUESTION_NUMANS_ADD. |
| get_more_choices_string() X-Ref |
| Language string to use for 'Add {no} more {whatever we call answers}'. |
| add_combined_feedback_fields($withshownumpartscorrect = false) X-Ref |
| No description |
| get_hint_fields($withclearwrong = false, $withshownumpartscorrect = false) X-Ref |
| Create the form elements required by one hint. param: string $withclearwrong whether this quesiton type uses the 'Clear wrong' option on hints. param: string $withshownumpartscorrect whether this quesiton type uses the 'Show num parts correct' option on hints. return: array form field elements for one hint. |
| add_interactive_settings($withclearwrong = false,$withshownumpartscorrect = false) X-Ref |
| No description |
| set_data($question) X-Ref |
| No description |
| data_preprocessing($question) X-Ref |
| Perform an preprocessing needed on the data passed to {@link set_data()} before it is used to initialise the form. param: object $question the data being passed to the form. return: object $question the modified data. |
| data_preprocessing_answers($question, $withanswerfiles = false) X-Ref |
| Perform the necessary preprocessing for the fields added by {@link add_per_answer_fields()}. param: object $question the data being passed to the form. return: object $question the modified data. |
| data_preprocessing_extra_answer_fields($question, $extraanswerfields) X-Ref |
| Perform the necessary preprocessing for the extra answer fields. Questions that do something not trivial when editing extra answer fields will want to override this. param: object $question the data being passed to the form. param: array $extraanswerfields extra answer fields (without table name). return: object $question the modified data. |
| data_preprocessing_extra_answer_field($answer, $field) X-Ref |

| data_preprocessing_hints($question, $withclearwrong = false,$withshownumpartscorrect = false) X-Ref |
| Perform the necessary preprocessing for the hint fields. param: object $question the data being passed to the form. return: object $question the modified data. |
