snapshotting contact data

[fundecassa]

I would like to implement something like the button "select" (account) in the contacts-editview in my new module with the only difference, that I do not want to pull data from accounts but from contacts to my new module. Is this possible in an decent (upgradeable) manner?
I want to snapshot (not screenshot! .-) )at certain points specific contacts-data and transfer them to my self-created module.

Thanks for your ideas!

Try adding a custom field of type "relate" to your custom module and relate it to contacts.

Yes, I'm getting my data via "related" fields. As long as I want the actual data this is okay. But in my new module I want to cut (snapshot) my relation and save the data after a certain time just by clicking something like "fix-data". How should I do this?
Thanks for replying!

I am not sure I understand what it is you are trying to accomplish. Can you provide a more concrete example?

In the module contacts a maintain my contact-data up-to-date. In the new module I use part of these contact-data during the lifetime of a certain project (The contact-data (lets say phone-number and institutional function). If during my project data in contacts change also in the new module the data in the "related"-fields change. So far everything okay.

When my project ends I want to fix these contact-data from inside the new module in a separate record just by one click. For example I want to know in two years under which phone-number and institutonal function I did communicate with the respective Person at the lifetime of the project, although now I have different actualized data in the contacts module.

Wouldn't a simpler solution be to create a logic hook that looks at the status of the project to check if it is "completed" and then copy the data automatically if so?

Aha, "logic hook" is the keyword, I will try it and come back to you. Thank you very much!
