more issues with following and unfollowing!

This time there is supposed to be a check to the database of if i'm following a user or not. If I am, its supposed to display "Unfollow", if i'm not its supposed to display "follow"

I have a user_follow table that contains the ID of the follower and the user followed, under the names "follower" and "user"

The code to get these:

$check_following = mysql_query("SELECT `follower`, `user` FROM user_follow WHERE `user`=$p_id'");
$follow_query = mysql_fetch_array($check_following);

p_id is the profile i'm looking at. The if statement:

if(isset($_SESSION['id']) && $p_id != $_SESSION['id'])
      {
          if ($follow_query['follower'] == $_SESSION['id'] && $follow_query['user'] ==$p_id)
               { 
                 echo 'Unfollow';
               } 
          else { 
                 echo 'Follow';
               } 
 }

Problem is, unfollow shows on 1 out of the 3 profiles i'm following, and follow shows on 2 profiles i'm following, echoing $follow_query['follower'] shows 1, which isn't me (also shows 1 for another user)

Any ideas?

Thanks guys

mysql_fetch_array如果 sql 查询有更多结果，则返回多于一行。要正确迭代结果，请使用：while ($row = mysql_fetch_array($result)){$array[] = $row;}
