Media Library – Users view

Hi,

I have a front-end insert on my wordpress website. And when the user is uploading images I want that the logged user can access/view only their images. It’s not logic to see all the media library database. Just the administrator can see all the images.

I’ve tried something like:

function mymo_parse_query_useronly( $wp_query ) {
    if ( strpos( $_SERVER[ 'REQUEST_URI' ], '/wp-admin/upload.php' ) !== false ) {
        if ( !current_user_can( 'level_5' ) ) {
            global $current_user;
            $wp_query->set( 'author', $current_user->id );
        }
    }
}

add_filter('parse_query', 'mymo_parse_query_useronly' );

But didn’t work !

Appreciate some help.
