Hi there,

I’m trying to automatically retrieve the Prolific ID from the survey URL and store it in my data, but I’m having trouble getting it to work. Here’s what I’ve done so far:

  1. Create a study link on Prolific: https://www.soscisurvey.de/studyname/?PROLIFIC_PID={{%PROLIFIC_PID%}}&STUDY_ID={{%STUDY_ID%}}&SESSION_ID={{%SESSION_ID%}}&q=qnr2

  2. Use PHP code:
    if (!isset($id)) {
    $id = readGET('PROLIFIC_PID');
    registerVariable($id);

My question: Do I also need to specify a variable name such as "PROLIFIC_PID" under Post/GetVariable and do I have to tick boxes for "javaScript" or "AdBlocker"?

Thank you so much for your help!

I recommend not to use PHP code, but only a question "device and transmitted variables" instead. Place this question on the first page.

do I have to tick boxes for "javaScript" or "AdBlocker"?

No, except if you want to know if the respondents have JavaScript or an AdBlocker enabled.
