[PLUGIN] Change the Wordpress posts page to show only the author’s own posts

The code below checks to see if a user has admin capabilities. If the user is not an admin, he will only see his own posts listed on the posts edit screen, making it easier for him to locate his own posts.

function mypo_parse_query_useronly( $wp_query ) {
    if ( strpos( $_SERVER[ 'REQUEST_URI' ], '/wp-admin/edit.php' ) !== false ) {
        if ( !current_user_can( 'update_core' ) ) {
            global $current_user;
            $wp_query->set( 'author', $current_user->id );
        }
    }
