From 52e8aa798a23b2832a748189b42c3bc77d65c9c7 Mon Sep 17 00:00:00 2001 From: Evan Prodromou Date: Fri, 19 Feb 2010 08:16:45 -0500 Subject: Refactor subs_* functions for remote use The subs_* functions in subs.php have made a lot of assumptions about users versus profiles. I've refactored the functions to be methods of the Subscription class instead, and to use Profile objects throughout. Some of the checks for blocks or existing subscriptions depended on users or profiles, so I've moved those methods around a bit. I've left stubs for the subs_* functions until we get time to replace them. --- classes/Profile.php | 12 ++++ classes/Subscription.php | 154 +++++++++++++++++++++++++++++++++++++++++++++-- classes/User.php | 19 +----- 3 files changed, 165 insertions(+), 20 deletions(-) (limited to 'classes') diff --git a/classes/Profile.php b/classes/Profile.php index 494c697e4..6b396c8c3 100644 --- a/classes/Profile.php +++ b/classes/Profile.php @@ -868,4 +868,16 @@ class Profile extends Memcached_DataObject return $uri;
