Php codeigniter中的原则分页

我对条令和将条令用于CI应用程序是新手。到目前为止还不错，但我一直坚持分页。Paginator类返回该对象，但当我尝试获取计数时，会出现以下错误

//_clone method called on non-object in D:\xampp\htdocs\globalauto\application\libraries\Doctrine\ORM\Tools\Pagination\Paginator.php

我们将非常感谢你的帮助

谢谢

public function getAllLogisitics()
{
    $logisticsMeta = new LogisticsMeta();
    $logisticEntity = $this->em->getRepository('models\Entities\Logistics');
    $query =$this->em->createQuery('SELECT * FROM logistics')->setFirstResult(0)
                   ->setMaxResults(10);
    $paginator = new Paginator($query, false);
    $c = count($paginator);//get error on this line
    foreach ($paginator as $logistic) {
        echo $logistic->getStatus() . "\n";
    }
}

这是我在条令页面上尝试过的

我使用了doctrine 2.0.1版，它是通过CI分页实现的

public function getAllLogisitics($limit, $start)
{
    $data = array();
    $this->db->limit($limit, $start);
    $this->db->order_by('id', 'desc');
    $logisticsList = $this->db->get("logistics");
    $logistics_data = array();
    $logistic = $this->em->getRepository('models\Entities\Logistics');
    foreach ($logisticsList->result_array() as $logistics) {
        $logisticsObj = $logistic->findby(array("id" => $logistics["id"]));
        $logisticsTemp['Logistics'] = $logisticsObj;
        $logisticsTemp['LogisticsMeta'] = $this->functions->getMeta('models\Entities\LogisticsMeta', 'logistics', $logistics["id"]);
        $logistics_data[] = $logisticsTemp;
    }
    return $logistics_data;
}
