getAfterParticipationSuppressionAnswerPostVars()

assErrorTextGUI::getAfterParticipationSuppressionAnswerPostVars

(

)

Returns a list of postvars which will be suppressed in the form output when used in scoring adjustment.

The form elements will be shown disabled, so the users see the usual form but can only edit the settings, which make sense in the given context.

E.g. array('cloze_type', 'image_filename')

Returns

string[]

Parameters

integer	$active_id	The active test id
integer	$pass	The test pass counter
boolean	$graphicalOutput	Show visual feedback for right/wrong answers
boolean	$result_output	Show the reached points for parts of the question
boolean	$show_question_only	Show the question without the ILIAS content around
boolean	$show_feedback	Show the question feedback
boolean	$show_correct_solution	Show the correct solution instead of the user solution
boolean	$show_manual_scoring	Show specific information for the manual scoring output

Returns

string HTML solution output
