Member Function Documentation

get_action_menu_link()

core_question\local\bank\question_action_base::get_action_menu_link ( \stdClass $question )

inherited

Return the action menu link for this action on the supplied question.

For most actions, you will just need to override {

See also

get_url_icon_and_label()}. You only need to override this method if you need to pass additional attributes to {

action_menu_link_secondary}, or use a different class to render the link.

Parameters

stdClass

$question

Return values

action_menu_link|null

Reimplemented in qbank_tagquestion\tags_action.

get_extra_joins()

core_question\local\bank\view_component::get_extra_joins ( )

inherited

Return an array 'table_alias' => 'JOIN clause' to bring in any data that this feature requires.

The return values for all the features will be checked. It is OK if two features join in the same table with the same alias and identical JOIN clauses. If two features try to use the same alias with different joins, you get an error. Tables included by default are question (alias q) and those defined in {

See also

view\get_required_joins()}

It is importnat that your join simply adds additional data (or NULLs) to the existing rows of the query. It must not cause additional rows.

Return values

string[]

'table_alias' => 'JOIN clause'

Reimplemented in core_question\local\bank\action_column_base, core_question\local\bank\column_base, qbank_viewcreator\creator_name_column, and qbank_viewcreator\modifier_name_column.

get_menu_position()

qbank_exporttoxml\export_xml_action::get_menu_position

(

)

Return an integer to indicate the desired position in the menu for this link, smaller at the top.

The standard menu items in Moodle core return these numbers: 100 preview_action 200 edit_action 250 copy_action 300 tags_action 400 delete_action 500 history_action 600 export_xml_action (So, if you want your action at a particular place in the order, there should be space.)

If two actions get the same order number, then the tie-break on the sort is plugin name, then the order returned by get_question_actions for that plugin.

Return values

int	desired position. Smallest at the top.

Reimplemented from core_question\local\bank\view_component.

get_required_fields()

core_question\local\bank\view_component::get_required_fields ( )

inherited

Use table alias 'q' for the question table, or one of the ones from get_extra_joins.

Every field requested must specify a table prefix.

Return values

string[]

fields required.

Reimplemented in core_question\local\bank\action_column_base, core_question\local\bank\checkbox_column, core_question\local\bank\column_base, core_question\local\bank\edit_menu_column, mod_quiz\question\bank\question_name_column, mod_quiz\question\bank\question_name_text_column, qbank_viewcreator\creator_name_column, qbank_viewcreator\modifier_name_column, qbank_viewquestionname\question_name_idnumber_tags_column, qbank_viewquestionname\viewquestionname_column_helper, qbank_viewquestiontext\question_text_row, and qbank_viewquestiontype\question_type_column.

qbank_exporttoxml\export_xml_action::get_url_icon_and_label ( \stdClass $question )

protected

Get the information required to display this action either as a menu item or a separate action column.

For most actions, it should be sufficient to override just this method. {

See also
