Question

How can I query my database to check if user_id or friend_id are equal to the logged in users ID and that their friendship_status has been accepted.

Here is the MySQL code I got so far.

SELECT COUNT(id) as num 
FROM users_friends 
WHERE users_friends.user_id = '$user_id' 
AND friendship_status = '1'

Here is my MySQL table.

CREATE TABLE users_friends (
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
user_id INT UNSIGNED UNSIGNED NOT NULL,
friend_id INT UNSIGNED NOT NULL,
friendship_status TINYINT(1) UNSIGNED NOT NULL DEFAULT 0,
date_created DATETIME NOT NULL,
);

Answer 1

SELECT COUNT(id) as num 
FROM users_friends 
WHERE (
    user_id = '$sanitized_user_id' 
    OR friend_id = '$sanitized_user_id'
  )
  AND friendship_status = '1'
