                         array('wishlist_id','customer_id'))
                         ->where('main_table.product_id = '.$_product->getId().' AND t2.customer_id='.$customer_id);
        $count = $wishlist->count();
        $wishlist = Mage::getModel('wishlist/item')->getCollection();
    }
    else {
        $count="0";
    }

    if ($count) :
        return true;
    else:
        return false;
    endif;
