I'm trying to use civicrm_post hook to retrieve a custom value from a contribution form. the value is then mapped and saved in a different custom field.

the setValues is working fine. but i'm not able to retrieve the form value. I'm using:

$get_params = array('entityID' => $contribution_id,
        'custom_1' => 1 );
$values = CRM_Core_BAO_CustomValueTable::getValues($get_params);
where $contribution_id is the $objectId passed to the hook. I know that value is valid -- there is indeed a contribution id at that point in the process. But it seems the custom value is not yet saved, and thus not retrievable via that entity id at the point the post hook is called. the other values passed to the hook (like $objectRef) don't include the form values. what's the best way to retrieve that value?

I ended up just grabbing from $_REQUEST, and that worked fine.

but I'm running into another issue -- the value of the field doesn't load on edit
this is in a new contribution form (backend), so where I'm at is the field appears fine, I can select and save, value is stored, but when I edit and existing record, the value does not load -- and thus if I proceed to save, the value is lost.

it's definitely saving the value on the initial form load/save. I'm not seeing where I need to preload the value on edit.

I did that and it worked. Retrieved using:
CRM_Core_BAO_CustomValueTable::getValues

but it just seems clumsy. i add the element to the form, then need to retrieve the value in case i'm editing an existing record and set it as the default. i guess I expected that quickform addElement would do the work of retrieving an existing value. oh well.
