I've got the following problem: I want to use a survey in addition to another web-based test(php). Now i need to find a way to match the data of the survey with the one of the other test.
I wanted to use an 8-digit number submitted by the participant together with the current time to avoid matching numbers by different participants. Is it even possible to autmatically add the current time to the end of the participants answer? And if yes: how can I pass the id number to my other test?
