  1. Put this in your functions.php an then call it when you want

     function getIdFromMeta( $meta_key, $meta_value ) {
    global $wpdb;
    $pid = $wpdb->get_var( $wpdb->prepare("SELECT post_id FROM $wpdb->postmeta WHERE meta_value = '$meta_value' AND meta_key = '$meta_key' ORDER BY post_id DESC") );
    if( $pid != '' )
        return $pid;
    else 
        return false;
}

    Hope it helps
