Good afternoon.  recipes that worked for joomla 1.5 jomsocial 2.2.4 now will not work with joomla 1.7 jomsocial 2.2.4 / what could be the problem?

sample  recipes (this code puts the module, depending on category)

events

$ categoryid = "";
if (($ option == "com_community") and ($ view == "events")) {
$ categoryid = JRequest:: getInt ("categoryid", 0);
$ eventid = JRequest:: getInt ("eventid", 0);
   if ($ eventid> 0) {
     $ query = "select catid from #__community_events where id =". $ eventid;
     $ db-> setQuery ($ query);
     $ categoryid = $ db-> loadResult ();
   }}
if ($ categoryid == 1) return 104;

groups

$ categoryid = "";
if (($ option == "com_community") and (($ view == "groups") | | ($ view == "videos") | | ($ view == "photos"))) {
   $ categoryid = JRequest:: getInt ('categoryid', 0);
   if ($ categoryid == 0
        and ($ groupid = JRequest:: getInt ("groupid", 0)) i = 0
     ) {
     $ query = "select categoryid from #__community_groups where id =". $ groupid;
     $ db-> setQuery ($ query);
     $ categoryid = $ db-> loadResult ();
   }
}
if ($ categoryid == 3) return 104;

videos

$ catid = "";
if (($ option == "com_community") and ($ view == "videos")) {
   $ catid = JRequest:: getInt ("catid", 0);
   $ videoid = JRequest:: getInt ("videoid", 0);
   if ($ catid == 0 and $ videoid! = 0) {
     $ query = "select category_id from #__community_videos where id =". $ videoid;
     $ db-> setQuery ($ query);
     $ catid = $ db-> loadResult ();
   }
}
if ($ catid == 2) return 62; / /



advise where and what to fix. can cause a syntax?
