Hello,

I have a problem with the responses of my survey not being saved. Recipients have told me they finished the survey and got a conformation email, but their data is nowhere to be found. This happened to about 5/20 people that filled in the survey. It seems to be that their data is lost. How is this possible?

They got a conformation mail that they finished the survey. Some of them had partially filled in the survey before and then saved this. I do have the data form those half finished responses.

They are all invited by email. In the respons menu it says that 14/19 have completed the survey, but in the acces code menu it says that 19/20 have completed the survey.

I really hope someone can help me get the data back! It's quite a long survey so I don't wanna ask them to take it again. Also I'm afraid that when I ask them to take it again it won't save again. Does anybody have a solution or is familiar with this problem?

Thanks for your help  

What LimeSurvey version are you using? What is "the acces code menu"?

It says version 2.05+ Build 131209.

I'm using a Dutch version so I don't know how it's called in the English version but with the "acces code menu" I was referring to the button that let's you control the codes that you send to partipants so they can enter the survey. When you have the main menu of the survey it's the button with the logo of the 3 men. It should say something like control (acces) codes.

Ah, in English, that's the "Tokens" button and leads to the token table which is separate from the answers table.

Unfortunately, I don't have a solution for your problem. I've run hundreds of surveys on 2.05 and never lost data. I suppose you exported the data to see if those response sets are actually missing (not just missing in the LS interface).

I have the same question. Limesurvey sent a "basic admin notification" email to the respondent. But I can't find the record in the database.

I checked the limesurvey_id database in MYSQL, and didn't find the record there.

I guessed: Because I turned on "Participant may save and resume later". When different participants from the same IP address using the same token, the newer will replace the older's record? Then I can't see the older's record.

Or maybe I turned "Allow multiple responses or update responses with one token?" to yes. And different participants using the same token. The newer will replace the older's record?

If token is set , not anonymous + reponse token persistence : one token => one answer
If you want multiple answer with one token : you must disable "reponse token persistence" and enable "Allow multiple responses or update responses with one token?".

If user click on "save" : a form to have a user/pass is shown.

If token is set, and the use left set to 500, still one token=>one answer? It seems 500 persons can take the survey.

Thank you very much for your kindness, DenisChenu !

I created a token name test, and set the uses left to 500. Then
A. Set "Allow multiple responses or update responses with one token" to YES, and set "response token persistence" to NO

B. Set "Allow multiple responses or update responses with one token" to NO, and set "response token persistence" to YES

What is the different between A and B? In which case, 500 persons can take the survey using the same token?

I forgot I used A or B. Anyway, a few responses aren't being saved. I don't know why? Would you please do me a favor and let me know it? thanks again!

I forgot the use_left ....

I think "response token persistence" do .... nothing here .....

A: after 500 survey submission : an user can submit again and again survey (Allow multiple responses)
B: after 500 survey submission : new survey with this token is disable (not Allow multiple responses)

thank you very much! One more question

When "Allow multiple responses or update responses with one token" set to YES

If two person's IP address are the same and the token are the same. When the first person complete the survey, the second person begin to fill the survey. Will the first person's record be replaced by the first one? If so ,that why some response aren't being saved.

Another possibility, when the first person filling the survey, the second one begin to fill the survey. Will the second's response replace the first's? If yes, that that why some response aren't being saved.

Yes, think so.

You can test yourself with 2 browser .....

2 different $_SESSION , same token (one time ) : each time a user "submit" a page (click next/previus or save) the DB is updated to his $_SESSION.

PS: same IP or not : it's the same. It's $_SESSION only and token only. Different IP : same than same IP.
