Question

$sql = "select body, stamp from posts where user_id = '$userid' order by stamp desc";

NOTE: the above query works fine. What I want to do is also select username from my users table, and display the username that matches the user_id.

I have edited the above statement like so, and it doesnt work. Can someone suggest the correct query? My goal is to also be able to display usernames. in addition to simply displaying user_id.

$sql = "select body, stamp from posts AND username from users where user_id = '$userid' order by stamp desc";

My goal is to also be able to display usernames. instead of simply user_id.

You’ll need to use a JOIN to bring the two tables together on the matching field, so something like:

$sql = "SELECT p.body, p.stamp, u.username FROM posts p INNER JOIN users u ON p.user_id=u.user_id WHERE p.user_id='$userid' ORDER BY p.stamp DESC";
