I am thinking about exploring the LimeSurvey API. The API use case I have in mind is...

• to create a copy of a survey
• to then alter the the "Always hide this question" attribute of 2 or 3 questions on a case by case basis
• to then activate the survey to collect responses

Is this possible?

I have not tested but I would say "probably". You can use the set_question_properties() method to adjust a question - probably the easiest way to find out what the $aQuestionData requires is to use the get_question_properties() method on an existing question.

Cool, thanks Tony...

I was also thinking that this could be done by editing the question via the lime_question_attributes table.

Once you know the qid, it seems that you just need to add a 'hidden' entry in the 'attribute' column... does that also sound possible to you as another way to achieve the same outcome?

Sure, I suppose you could modify the database values directly - that's what the API does for you.

Cool, thanks...
