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 }
