Member Function Documentation

assOrderingQuestion::addAnswer (   $answertext = "",
  $solution_order = -1 
)

Adds an answer for an ordering choice question.

The students have to fill in an order for the answer. The answer is an ASS_AnswerOrdering object that will be created and assigned to the array $this->answers.

Parameters
string$answertextThe answer text
double$pointsThe points for selecting the answer (even negative points can be used)
integer$orderA possible display order of the answer
integer$solution_orderAn unique integer value representing the correct order of that answer in the solution of a question public
