Detailed Description

Missing word question importer.

This Moodle class provides all functions necessary to import and export one-correct-answer multiple choice questions in this format:

As soon as we begin to explore our body parts as infants we become students of {=anatomy and physiology ~reflexology ~science ~experiment}, and in a sense we remain students for life.

Each answer is separated with a tilde ~, and the correct answer is prefixed with an equals sign =

Percentage weights can be included by following the tilde with the desired percent. Comments can be included for each choice by following the comment with a hash mark ("#") and the comment. Example:

This is {=the best answer\comment on the best answer ~75a good answer\comment on the good answer ~a wrong one\comment on the bad answer}

qformat_default::readquestions ( $lines)
protectedinherited

Parses an array of lines into an array of questions, where each item is a question object as defined by readquestion().

Questions are defined as anything between blank lines.

NOTE this method used to take $context as a second argument. However, at the point where this method was called, it was impossible to know what context the quetsions were going to be saved into, so the value could be wrong. Also, none of the standard question formats were using this argument, so it was removed. See MDL-32220.

If your format does not use blank lines as a delimiter then you will need to override this method. Even then try to use readquestion for each question

Parameters
arraylines array of lines from readdata
Return values
arrayarray of question objects
