When we use multiple and (where) condition with last (where + or where) the where condition fails most of the time. for that we can use the nested where function with parameters passing in that.
$feedsql = DB::table('feeds as t1')
->leftjoin('groups as t2', 't1.groups_id', '=', 't2.id')
->where('t2.status', 1)
->whereRaw("t1.published_on <= NOW()")
>whereIn('t1.groupid', $group_ids)
->where(function($q)use ($userid) {
$q->where('t2.contact_users_id', $userid)
->orWhere('t1.users_id', $userid);
})
->orderBy('t1.published_on', 'desc')->get();
The above query validate all where condition then finally checks where t2.status=1 and (where t2.contact_users_id='$userid' or where t1.users_id='$userid')
