quiz.api.php in Quiz 8.5

quiz.api.php Hooks provided by Quiz module.

These entity types provided by Quiz also have entity API hooks. There are a few additional Quiz specific hooks defined in this file.

quiz (settings for quiz nodes) quiz_result (quiz attempt/result) quiz_result_answer (answer to a specific question in a quiz result) quiz_question (generic settings for question nodes) quiz_question_relationship (relationship from quiz to question)

So for example

hook_quiz_result_presave($quiz_result)

• Runs before a result is saved to the DB.

hook_quiz_question_relationship_insert($quiz_question_relationship)

• Runs when a new question is added to a quiz.

You can also use Rules to build conditional actions based off of these events.

Enjoy :)
