Member Function Documentation

◆ build_editform()

feedback_item_base::build_editform ( $item,
$feedback,
$cm )
abstract

Creates and returns an instance of the form for editing the item.

Parameters
stdClass$item
stdClass$feedback
cm_info | stdClass$cm

Reimplemented in feedback_item_captcha, feedback_item_info, feedback_item_label, feedback_item_multichoice, feedback_item_multichoicerated, feedback_item_numeric, feedback_item_pagebreak, feedback_item_textarea, and feedback_item_textfield.

◆ can_switch_require()

feedback_item_base::can_switch_require ( )

Wether this item can be set as both required and not.

Return values
bool

Reimplemented in feedback_item_captcha, feedback_item_info, feedback_item_label, and feedback_item_pagebreak.

◆ compare_value()

feedback_item_base::compare_value ( $item,
$dbvalue,
$dependvalue )

Compares the dbvalue with the dependvalue.

Parameters
stdClass$item
string$dbvalueis the value input by user in the format as it is stored in the db
string$dependvalueis the value that it needs to be compared against

Reimplemented in feedback_item_label, feedback_item_multichoice, and feedback_item_multichoicerated.

◆ complete_form_element()

feedback_item_base::complete_form_element ( $item,
$form )
abstract

Adds an input element to the complete form.

This method is called:

  • to display the form when user completes feedback
  • to display existing elements when teacher edits the feedback items
  • to display the feedback preview (print.php)
  • to display the completed response
  • to preview a feedback template

If it is important which mode the form is in, use $form->get_mode()

Each item type must add a single form element with the name $item->typ.'_'.$item->id This element must always be present in form data even if nothing is selected (i.e. use advcheckbox and not checkbox). To add an element use either: $form->add_form_element() - adds a single element to the form $form->add_form_group_element() - adds a group element to the form

Other useful methods: $form->get_item_value() $form->set_element_default() $form->add_validation_rule() $form->set_element_type()

The element must support freezing so it can be used for viewing the response as well. If the desired form element does not support freezing, check $form->is_frozen() and create a static element instead.

Parameters
stdClass$item
mod_feedback_complete_form$form
