Hi
Is it possible to create an update of an extension, e.g. Gallery, where the new version will perform database modifications only once, like TL's liveupdate tool. Is there a script or some hook that can be run once, and then removed. I'm trying to comply to the new Comments system for the Gallery, but this means that when you just straight upgrade, TL will simply remove the tl_gallery_comments table, removing all existing comments. I'd like to convert them to entries in tl_comments before the database update is run to remove the table tl_gallery_comments
Any ideas? Leo, Peter, Fred?
