How can I hook into a merge ?

After merging two contacts I want to do some actions. Is their a way/hook to know which addresses/phones/... are updated, deleted or kept ? I tried the hook_civicrm_post, hook_civicrm_pre or even the hook_merge but I can't get the info I want (eg. the addresses that are changed do not pass these hooks).

Does anyone have a clue ? Thx!

The merge is done on a per-object-type basis not a per-object basis. Since in the UI the user gets to choose whether or not to merge addresses, but they don't get to pick and choose particular addresses to merge.
The merge hook will provide you with a list of object types that are going to be merged (and it will fire again after the merge is complete, I think). Look at the core code to see what's actually going on.
But basically your hook code will need to do something like this (pseudocode):

Code: [Select]

if (addresses are going to be included in the query) {
  civicrm_api('address', 'get', array(pass in contact id of the old contact));
}
