Reviewing system data fields

Question

I was browsing through the Sawtooth Software help and reviewing system data fields. I noticed a few were missing.

The missing system data fields are as follows ...

sys_UserAgent
sys_ShowPrev
sys_CheckSum
system fields associated to "Randomizing Question/Pages/Blocks"

I was also curious as to what sys_ShowPrev and sys_CheckSum are?

Thank you.

Answer 1

sys_ShowPrev is set to true if the respondent entered the survey by page 1 and false if they used the bypass link. It means show the previous button on page 2 or not

sys_Checksum is a unique value per respondent for validating if the respondent came from our system or not. Its a security value so hackers can't fake a respondent because we expect a certain value with the respondent number and if they don't match it rejects the respondent data submitted

Hope that helps

Comments

Thanks for the feedback Mike. Always appreciated mate.

As mentioned earlier, these system fields are not in the Sawtooth Software help so you might want to pop them in down the track.

Thanks again.
