Mysql kan ikke finde ud af OR

Hej Eksperter,

Hvorfor kan min mysql ikke finde ud af dette?

        $strPost = $mysqli->real_escape_string($_GET['title']); $numbPost = $mysqli->real_escape_string((int)$_GET['id']);
        $getPost = $mysqli->query( "SELECT * FROM lb_articles WHERE article_url='".$strPost."' OR article_id='".$_GET['id']."' LIMIT 1" ) OR DIE( $mysqli->error );
        $showPost = $getPost->fetch_assoc();

        if ( $_GET['id'] ) { echo "<pre>";print_r($showPost);echo "</pre>";/* header('Location:'.$showPost['article_url'].'.html', true, 301); */ } // REDIRECT URL
        else {
            echo "<h1>".$showPost['article_titel']."</h1><hr>";
            echo "<span>".str_replace(array(',',', '),' &#9134; ',$showPost['article_category'])." - ".$showPost['article_updated']."</span>";
            echo "<p>".nl2br($showPost['article_content'])."</p>";
            echo "<strong>URL: <input size=\"90\" value=\"http://".$_SERVER['SERVER_NAME']."/".$showPost['article_url'].".html\"> — ".$numbPost."</strong>";
           
            // echo "<pre>"; print_r($showPost); echo "</pre>";
        }

Denne mysql linje:  SELECT * FROM lb_articles WHERE article_url='".$strPost."' OR article_id='".$_GET['id']."' LIMIT 1
