php - Getting posts from your friends -

-

what trying accomplish fill news feed full of posts friends of $username session username.

the problem have if user not following or not being followed (is not in follow table) not see own posts in news feed.

everything else seems work fine.

user can see post , people follows post. user can see posts if following or being followed. user cannot see own post if not following nor being followed.

select  p.* posts p join follow f on p.by in (f.person_being_followed, '$username')   '{$username}' in (f.person_following, p.by)  order p.id desc

this code page echo information

        <?  $get_posts = mysql_query("select  p.* posts p join follow f on p.by in (f.person_being_followed, '$username')  ### ,$username' shows logged users posts, if in follow table ### '{$username}' in (f.person_following, p.by)  ## p.by shows person posted logged in, if in follow table ## order p.id desc") or die(mysql_error());  while ($post_row = mysql_fetch_assoc($get_posts)) {      include './includes/newsfeed/postdetails.tpl';     include './includes/newsfeed/likeinfo.tpl';     include './includes/newsfeed/fandlname.tpl';     include './includes/newsfeed/deletepostbutton.tpl';  ?>       <div style='display: inline-block;width: 560px;padding-top: 10px;padding-bottom: 10px; border-bottom: 1px solid rgba(0,0,0,0.1);'>     <a style='float: left;' href='./profile.php?u=<?     echo $post_by; ?>'><img src='' height='50px' width='50px'/></a>     <div style='float: right; width: 500px;'>     <p style='color: rgb(59, 152, 96);font-weight: bold; font-size: 13px; line-height: 1.38;font-family: 'lucida grande',tahoma,verdana,arial,sans-serif;'><a style='color: rgb(59, 152, 96); font-weight: bold; font-size: 12px; line-height: 1.38;text-decoration: none;' href='./profile.php?u=<?     echo $post_by; ?>'><?     echo "$fnamepost  $lnamepost"; ?></a></p>     <p style='color: rgb(51, 51, 51); font-size: 13px; line-height: 1.38; font-family: 'lucida grande',tahoma,verdana,arial,sans-serif;'><?     echo $post_content; ?></p>      <div style='margin-top: 5px;'><a href='./scripts/like.php?pid=<?     echo $post_id; ?>' style='color:rgb(109, 180, 137); font-size: 11px;line-height: 1.28;'><?     echo "$likedornot ($countlikes)"; ?></a><a href='#' class='comment_button' style='margin-left: 10px;color:rgb(109, 180, 137); font-size: 11px;line-height: 1.28;'><?     echo "comment"; ?></a><?     echo $deletecodevariable; ?></div>  <?     include './includes/newsfeed/comments.tpl';     ?> </div></div> <? } ?>

mysql table follow

also table follow

mysql table posts

and table posts

replace 

$get_posts = mysql_query("select posts.*             posts inner join follow             on posts.by=follow.person_being_followed           follow.person_following = $username order posts.id desc");

with 

$get_posts = mysql_query("select posts.*             posts inner join follow             on posts.by=follow.person_being_followed           follow.person_following = '$username' order posts.id desc") or die(mysql_error());

use mysql_error() debugging purpose see if error message printed out

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...
