Hi,

I have one query If any participants is in CPDB. We can add that participants to various survey to participate in survey, OK.

If I have for Ex. Mr. X is in my CPDB and he is enrolled in 5 different survey. But the condition is that, he can only attempts any 3 surveys out of 5 in one month. after one month he is able to attempt remaining survey.

So how can I restrict those participants according to above conditions to attempt surveys.

Thanks & Regards

Not sure, maybe using beforeSurveyPage : test the number of allowed surveys for this participant, close the token if 3 is already used.
Need PHP development.

Thank you Denis

I know with the php development it can be solve but at the initial stage can we use CPDB Participant's survey information from where we can get the option for current no of submitted survey (completed survey). And from that it can be possible to avoid those participants in survey.

So, how do I link-up it with quota or using a logical condition for a first question to attempt in survey?
Thanks & Regards

Link between token table and CPDB are done (don't remind exactly but can be found in code).
About "quota" : why not a new column 'maxSurvey' in CPDB ?

Yes Denis,
But how can we link this CPDB with token table for attempts. I have share one of my participants with different survey and complete submission in one survey. So is that get any use.

Maybe somewhere here : github.com/LimeSurvey/LimeSurvey/blob/ma...rticipantsaction.php or github.com/LimeSurvey/LimeSurvey/blob/ma...ers/admin/tokens.php

Look at the token DB : if i remind there are a column for cpdb

OK Denis,

I added one attribute in CPDB as "Max Survey" and set a value for a one participant who is added in 6 different surveys with one survey is in complete status. So with the help of attribute value (Max survey) and the no of completed surveys can we restrict this participants, from attempting a survey.

In which function or file our token get validate for a survey participant table.

@siddhantwankar : you have to create your own code .... i'm not your dev.

A quick how to:

1. You go to the page that interest you (token submission)
2. You look at the form submission URL ("index.php/{SID}")
3. The route doesn't indicate any controller, so it's the default controller.
4. You google "Yii Default controller", and you find that the params to define the default controller is: 'defaultController'
5. You grep 'defaultController' and find that is defined in application/config/internal.php
6. In internal config, you find out that default controller for front end is application/controllers/survey/index.php

That means that your Token form is submitted to that file:
github.com/LimeSurvey/LimeSurvey/blob/ma...ers/survey/index.php

7. You go back to the token form, and find that the token is submitted as a POST param.
9. You go application/controllers/survey/index.php and look for where the POST request is parsed. You find this line:
github.com/LimeSurvey/LimeSurvey/blob/ma...survey/index.php#L89

10. Now that you found that all the POST params are inside an array called $param, and that your token input in the token form is named 'token', you look for $param in application/controllers/survey/index.php. That lead you to that line:
github.com/LimeSurvey/LimeSurvey/blob/ma...survey/index.php#L95


So now, you know that the token user submited is inside the variable $clienttoken.

11. From here, you look how it is used:
- as a param for _isClientTokenDifferentFromSessionToken() : clearly not what you are looking for.
- As a test inside inside a if statement testing that survey is finished : clearly not what you are looking for.
- To fill a variable called token in a statement commented as "// Get token" : that's what you're looking for.

12. So now, you look how this variable $token is used, and bingo, you find this statment:
github.com/LimeSurvey/LimeSurvey/blob/ma.../index.php#L383-L387

It means there are two ways to validate token, depending if survey allow edition of a response. If yes, then :

Only checks if the token exist in the Token model (see Yii documentation for findBytAttributes in an AR instance)

else: call to the token model, and use is usable+incomplete scope:
github.com/LimeSurvey/LimeSurvey/blob/ma.../Token.php#L298-L305
which just add conditions to check that the survey has not been completed already, and that it's valid.


So, as you see, it's a long work. As Denis told you, we're not your personal programmers. If you can't do that kind of operations, you should consider hiring a LimeSurvey partner. Also, now that I helped you, you should considering making a donation to LimeSurvey

@LouisGac : i think more on beforeSurvayPage evnt :
1st : test token
2nd : search the participant associated with this token
3rd : count the number of already done survey (this month for example)
4tth : redirect or show page with die if user survey > user max survey.
Some code example : framagit.org/SondagePro-LimeSurvey-plugi...rSurveyText.php#L175 or framagit.org/SondagePro-LimeSurvey-plugi...enByResponse.php#L93 or ....
But hacking code is a solution too ....

plugin for sure is the best way to do it. I was just answering his question:
