Hi, I've been struggling with getting data from 3 tables (users, feeds and friends). I want my code to get the users friends feeds and display it on the homepage. (Only the users and no one elses, and users who are not friends cannot see it. Sort of like what Twitter and Facebook are doing.)

My tables:

users

CREATE TABLE IF NOT EXISTS `users` (
  `user_id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(32) NOT NULL,
  `password` varchar(32) NOT NULL,
  `first_name` varchar(32) NOT NULL,
  `last_name` varchar(32) NOT NULL,
  `email` varchar(1024) NOT NULL,
  `active` int(11) NOT NULL DEFAULT '0',
  `email_code` varchar(32) NOT NULL,
  `avatar` varchar(55) NOT NULL,
  `type` int(1) NOT NULL DEFAULT '0',
  `protected` int(1) NOT NULL DEFAULT '0',
  PRIMARY KEY (`user_id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=7 ;

feeds

CREATE TABLE IF NOT EXISTS `feeds` (
  `id` int(6) NOT NULL AUTO_INCREMENT,
  `user_id` int(6) NOT NULL,
  `username` varchar(32) NOT NULL,
  `body` text NOT NULL,
  `date` datetime NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=6 ;

and buddys

CREATE TABLE IF NOT EXISTS `buddys` (
  `id` int(6) NOT NULL AUTO_INCREMENT,
  `user_one` int(6) NOT NULL,
  `user_two` int(6) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=3 ;

What I'm using to fetch the users data and feeds etc

$my_id = $_SESSION['user_id'];
                if ($getquery = mysql_query("SELECT * FROM feeds f
                INNER JOIN users u ON u.user_id = f.user_id 
                WHERE u.user_id = '$my_id' OR u.user_id IN 
                (SELECT b.user_one OR b.user_two FROM buddys b 
                WHERE b.user_one OR b.user_two = '$my_id')")){
                        // resultset processing goes here
                        while ($rows = mysql_fetch_assoc($getquery)){
                                $id = $rows['id'];
                                $user_id = $rows['user_id'];
                                $username = $rows['username'];
                                $body = $rows['body'];
                                $date = $rows['date'];
                                $dellink = "| <a href=\"http://localhost/vibeate/wigets/deletepost.php?id=" . $id . "\" style='color: grey;text-decoration:none;'>Delete</a>";
                                ?>
                                <h2><a href="users/<?php echo $username; ?>"><?php echo $username; ?></a></h2>
                                <p><?php echo $body; ?></p><br />
                                Posted on <?php echo $date; ?> <?php if ($user_id == $user_data['user_id'] || is_admin($user_data['user_id']) === true){
                                        echo $dellink;
                                }
                                ?>
                                <br /><hr width="500px">
                                <?php
                        }
                } else {
                        echo mysql_error();
                }
                        if (empty($id)){
                                echo '<h3>There\'s no posts to show...Be the first to post</h3>';
                        }

Is there any reason why you can't just do like:

<?php
session_start();
if($_SESSION['user_id'] == $_GET['user_id']) {
// Display
} else {
// Don't display
}
?>

I don't think it'll work with what I'm doing. Unless you can explain further o-o

Sorry I missed the part about friends too. That will only work for the user. I'll look back at this later if no one has the answer for you by then.
