2 1
3 1

Users and their ID
John Doe (1)
Juan dela Cruz (2)
Jane Doe (3)
Stranger (4)
Let say I'm already logged in as John Doe w/c has an ID of 1 and my friends are Juan dela Cruz and Jane Doe. I want to check the friend_id column using that function, since Stranger is not my friend, He wont be able to see posts/comments. If my codes wont be applicable, any changes or my codes are welcome. Thanks

Yes, only true or false. It will check if a user he/she is on the friend table. If not, don't show the post/comment otherwise show post/comment..
Take a look at code below. The logic under else statement is too long so i have to chop it. but the concept is still the same.
<?php if (!$db->viewFriendIfExistOnTbl($_SESSION['uid'])): ?>
<p class="okay">You can now post on your wall, however you can't able to view all your posts without
<a href="add-friend.php" title="Add Friend">adding a friend</a> on your circle. Remember, know your limit. Read <a href="house-rules.htm" title="House Rules">house rules</a>.</p>
<?php else: ?>// All my posts/comments including friend's posts/comments goes here.
<?php endif; ?>

I am creating a simple social network, and i want the post visible only on its circle of friends but the problem is...
let say user_a, user_b, user_c already registered and user_a and user_c connected/friends already and all their posts and comments are visible on their circle
but when user_b write a post oh his wall, it's also visible to user_a and user_c which i dont want to happen. I dont know what was wrong on codes below.
CREATE TABLE IF NOT EXISTS `user`(
`uid` INT(11) AUTO_INCREMENT PRIMARY KEY NOT NULL,
`uname` VARCHAR(25) NOT NULL,
`pword` CHAR(60) NOT NULL,
`fullname` VARCHAR(30) NOT NULL,
INDEX(`uname`)
) Engine = InnoDB DEFAULT CHARSET=utf8 COLLATE utf8_general_ci;
CREATE TABLE IF NOT EXISTS `friend`(
`fid` INT(11) AUTO_INCREMENT PRIMARY KEY NOT NULL,
`friend_id` INT(11) NOT NULL,
`my_id` INT(11) NOT NULL,
`stat` ENUM('0','1') NOT NULL,
INDEX(`friend_id`, `my_id`),
FOREIGN KEY(`friend_id`) REFERENCES `user`(`uid`)
ON UPDATE CASCADE
ON DELETE CASCADE
) Engine = InnoDB DEFAULT CHARSET=utf8 COLLATE utf8_general_ci;
public function viewFriendIfExistOnTbl($uid)
{
$query = $this->mysqli->query("SELECT `friend_id` FROM `friend` WHERE `my_id` = '$uid' LIMIT 1");
if ($query->num_rows > 0) {
return true;
}
}
