DB lookup vs Query ?

This is not what we want.

Is there a way to have such a dynamic or Ajax check of DB with one of CB tool ?

It's possible as there is API for it; it's just the field doesn't utilize it. So you'll need to implement it or develop a new plugin to provide such a feature.

I am coming back on this subject.

Is it possible now with Ajax fields to make such a DB lookup request at registration ? To check whether the submitting is allowed to do certain things for instance.

Thanks

No, DB Lookup field doesn't have AJAX usage implemented. The core fields ajax plugin just allows fields to be edited inline within your profile for example; it does not add ajax value checking to fields that don't have it.

Thanks Kyle

So there is no way to check a value dynamically in CB tables on the registration page ?

We have the reference id retrieved by PAP from the cookie, then inserted by auto action in the CB field prior to registration form display. This works ok and the new registrant is correctly set as sub affiliate of the reference id user retrieved.

Basically we want now to retrieve and display the userdata corresponding to this reference id in CB tables but we cannot find a way to do it as the reference id inserted by auto action is inserted by javascript.

Is there a way to have DB queries on CB tables by javascript after the registration form display ?
Can I use the cookie to make a query before the registration form display ?

No, the CB DB Lookup field does not have ajax validation. It will validate when the form is posted though.

You're already setting the ID to a CB field so you can do a query in a CB Query Field and substitute in the ID as needed. This won't be ajax of course and is only going to display on profile for example.
