php-Symfony2.为什么我不能从不同于1的页面发货

Question

我在尝试从不同于1的页面获取产品时遇到问题（有一个分页器）。如果有人能理解这个代码可能会很棒，我是symfony的新手。我认为这是由于这部分代码：

$this->get('request')->query->get('page', 1) 

这是控制器。它将数据数据发送到名为getAll.html.twig.的页面

/**
     * @Route("/get-all/{productRequestId}", name="userBuyerProductRequestGetAll", defaults={"productRequestId"=null} )
     * @Template()
     */
            public function getAllAction(Request $request, $productRequestId)
            {
                if ( !$this->getUser()->isAllowed("BUYER_PRODUCT_REQUEST")){
                    throw new AccessDeniedException();
                }
                if ( is_null($productRequestId) ) {
                    $productRequest = null;
                } else {
                    $productRequest = $this->getRepo()->find($productRequestId);
                }
                $company = $this->getUser()->getCompany();
                $criteria2 = $this->get('request')->query->get('criteria', "");
                $pagination2 = $this->get('knp_paginator')->paginate(
                $this->getDoctrine()->getRepository("dsarhoyaSCBundle:Product")->getByCompanyAndCriteriaDQL($company->getId(),$criteria2    ),
                $this->get('request')->query->get('page', 1)/*page number*/,
                $this->get('request')->query->get('resultsCount', 20)/*results per page*/,
                array('defaultSortFieldName' => 'p.name', 'defaultSortDirection' => 'asc')
                );
                if ( !$this->getUser()->getCompany()->getProductRequestAccess() ){
                    return $this->redirectToRoute("userPurchaseBidIndex", array("companyId"=>$this->getUser()->getCompany()->getId()));
                }
                if ( !$this->getUser()->isAllowed("BUYER_PRODUCT_REQUEST")){
                    throw new AccessDeniedException();
                }
                $options = new ProductRequestOptions([
                    "criteria"=> $request->get("criteria",""),
                    "user"=>$this->getUser()
                ]);
                $this->getDoctrine()->getManager()->getFilters()->disable('soft-deleteable');
                $pagination = $this->get('knp_paginator')->paginate(
                        $this->getRepo()->getByCompanyDQL($options),
                        $this->get('request')->query->get('page', 1)/*page number*/,
                        $this->get('request')->query->get('resultsCount', 20)/*results per page*/,
                        array('defaultSortFieldName' => 'r.creationTime', 'defaultSortDirection' => 'desc')
                    );
                return array(
                    "criteria"=> $options->criteria,
                    "requests"=>$pagination,
                    "company"=>$company,
                    "products"=>$pagination2, 
                    "criteria"=>$criteria2, 
                    "step"=>1,
                    "productRequest"=>$productRequest
                    );
            }

Answer 1

您必须在URL中传递页面变量。现在，总会有一个"1"值，这是没有意义的。

您的路线/search-product/{productRequestId}应至少包含一个页码。

作为您路线的一个元素：

/search-product/{productRequestId}/{page}

或作为获取参数：

/search-product/{productRequestId}/?page=number

其中number是您的页码。
