mySQL – WHERE, AND/OR selecting

Kolind

I’m trying to select all posts from database, (where an ID is = an id from another table, which connects the people i’m in network with) OR (to select posts where i’m the writer of the post.). Actually i’m trying to get posts from people in my network AND my own.

I’ve found out how to do this, but when using the OR clause it’s selecting the rows twice. So for example, if I write a post it’s duplicated when echo’ed out from database.

My mySQL:

$sId = validate::intValidate($_SESSION['userId']);
$sql = "SELECT * FROM networkPost
            INNER JOIN authentication
                ON networkPost.FK_networkYou=authentication.userId
            INNER JOIN network
                ON networkPost.FK_networkYou=network.networkYou
            WHERE networkMe=$sId AND FK_networkYou=networkYou OR networkYou=$sId
            ORDER BY networkPostId DESC";

networkYou is: The userId of the post writer.

So how do I select my own posts and my networks posts?
