i have created a participant table with 8 diff attributes [attribute_1, ... attribute_8}
I am trying to fill these attributes with some values, while having the survey set to be open for public registrating so that I can track the various traffic sources and campaigns.

is there a way to fill these attributes by passing them in a URl string say something like

limesurvey.com/index.php/781278?lang=en&...ttribute_1=mydayblog

so that i can store mydayblog under attribute_1 in participant table?

What is the intention that you want to store in TOKEN_ATTRIBUTES?
If you pass the parameters you may grab it in a simple question of type "short text".

And how do you add the parameter if you

@Joffm main purpose of storing in token_attribute is to ensure that i can capture which campaign a new registartion came from.

the survey can only be taken after registration, and email validation, so it's important that i have a token table active.

I could have used a short field to capture, but then the email validation is not a possibility and also same email can be used multiple times to access a survey.

is there a way to write into token table of a survey?

There are no included solution, and i don't know existing workaround solution

You allow register : you can create a plugin
1. Put url params in session in www.limesurvey.org/manual/BeforeRegister
2. Put the attributes in beforeTokenEmail / type : register

You could load the URL parameters into the register form via JavaScript.

Something like this in your theme custom.js file:

Hi Tony,

this is what i am trying to do, but being unsuccessful so far. Do i need any kind of authentication to write into token table? or just making a change in theme js file will do the trick?

Try it.

Lol

Thank you Tony !

Hi Tony,

Your method worked, but this means I have to make the fields visible for the respondent. And show whatever I am capturing through the URL.

Is there any other possibility of doing this with attributes hidden

Hide the input with CSS. Something like this in your custom.css file:
