Field difference between subscription and search ?

Hi !
Hope you'll understand my quite-bad english...
After buying different add-ons of your CB component, I just have a little question about a field... explanation :

- i've got a "select query field" which gives a list of all countries stored in a specific database table (so, quite long list) and the user can choose his country during his registration... that's OK

- i'm building a search page using the country as a criteria... so, actually, my same field shows the whole list (normal), but i'd like to show here only the list of countries which are recorded by users (so short list of only-used countries)...

As well, is it possible to create a "selecti field" which would be used for search page but not in the registration (database already filled)

Is it possible ? How to do this ?
Thank you by advance for your help...

It's not possible to have a separate userlist search query for a query select. Nor can one field search another field so no what you're wanting can't be done without developing a new fieldtype plugin to specifically do that.

Hi !
Thank you for your answer.

If what I wanted fisrt is not (easily) possible, could you please tell me where (which file, which function) the data provided in the registration AND in the profile edit are saved and insert in the database ?

My wish would be to fill automatically a column table at each record, depending on the value selected in another select filed...
I know how to write the query and the script, but I don't know where...

Thank you again !

We do not support core edits. If you want to push data from CB to a custom database table you can do that using CB Auto Actions acting on the after user registration trigger and/or after user update trigger.
