Query strings: Sending embedded Qualtrics field values to Pavlovia

Hi Mark,

Here is what I’m using:

https://run.pavlovia.org/Wake/ebbinghaus-darts/html/?order={e://Field/order}&researcher={e://Field/researcher}&participant={qo://QO_b7pqFlMnRyctNcr/QuotaCount}&id={e://Field/id}

Researcher is set as the PI’s ID so that I can effectively password protect the experiment and send people who haven’t read the PI sheet back to Qualtrics

I attempted to use a quota to pass a unique ID number. However, I’ve discovered that I’ve ended up with duplicate entries, presumably due to overlapping Qualtrics sessions.

I’ve therefore just added a randomly generated ID as well. In the survey flow I have
researcher = xxxx
participant = {qo://QO_b7pqFlMnRyctNcr/QuotaCount} id = {rand://int/1:1000}

I’m also using Qualtrics to randomly assign to conditions, so in this case I also have an evenly presented randomiser setting order as either 1 or 2.

Best wishes,

Wakefield
