request_as_friend.php

<?php //var need  both  members $mem1=preg_replace('#[^0-9]#i','',$_post['mem1']); $mem2=preg_replace('#[^0-9]#i','',$_post['mem2']);  if(!$mem1||!$mem2) {     echo "error .missing data";     exit(); } if($mem1==$mem2) {     echo "error can not add friend";     exit(); }  require_once('../include/connect.php');     if($_post['request']=="requestfriendship")  {      //check  there  not  request  pending  viewer  requesting  profile  owner      $sql = mysql_query("select id  friend_requests mem1='$mem1' , mem2='$mem2'limit1")or die(mysql_error());      $numrows = mysql_num_rows($sql);      if($numrows > 0)      {          echo "you have friend request pending  member. must approve  when view request list";          exit();      }       //check  there  not  request  pending  profile owner  not requesting  viewer      $sql = mysql_query("select id  friend_requests mem1='$mem2' , mem2='$mem1'limit1")or die(mysql_error());      $numrows = mysql_num_rows($sql);      if($numrows > 0)      {          echo "this user has requested friend already! check  friend  request on profile";          exit();      }      $sql = mysql_query("insert friend_requests(mem1,mem2,timedate) values('$mem1','$mem2',now())") or die (mysql_error("friend request  insertionn error"));      //$sql = mysql_query("insert pms(to,from,time,sub,msg) values('$mem2','xxxxx',now(),'new friend request','you have new  friend request waiting approval.<br /><br />navigate profile , check  friend request.<br /><br />thank you.')") or die (mysql_error("friend request pm insertionn error"));    echo "friend request  sent  succesfully. member must approve request";   exit();      } ?>

what post array returns mem1 , mem2?

however, shouldn't compare post data. or not both.

for example have logged in, id stored in session. opening user profile i.e.: http://yoursite.com/viewprofile.php?id=1001 . after passing jquery should check in php smth like:

if ($_get['id'] = $_sessiom['id']) {    //you cannot add }

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...
