我非常努力地让 KNP Paginator 工作。
我只想将一个实体添加到 id，但分页接受所有参数但不注意它！
这是我的代码：
使用 Symfony\Bundle\FrameworkBundle\Controller\Controller；使用 Symfony\Component\HttpFoundation\Request；
控制器类：
class StartController extends Controller
{
public function indexAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
$dql = "SELECT a FROM MainArtBundle:Art a";
$query = $em->createQuery($dql);
$paginator = $this->get('knp_paginator');
$pagination = $paginator->paginate(
$query,
$request->query->get('page', 1) /*page number*/,
8 /*limit per page*/
);
$pagination->setUsedRoute('homepage');
if (!$pagination) {
throw $this->createNotFoundException('Unable to find Art entities.');
}
return $this->render('MainShowBundle:Default:index.html.twig', array(
'pagination' => $pagination,
));
}
树枝模板：
<li>{{ knp_pagination_sortable(pagination, 'Oldest', 'a.id', {'direction': 'desc'}) }}</li>
<li>{{ knp_pagination_sortable(pagination, 'Newest', 'a.id', {'direction': 'asc'}) }}</li>
ArtEntity（整个 Entity 因为也许错误是由实体引起的，可以吗）

KNP 分页配置（在 config.yml 中）
knp_paginator:
page_range: 5 # default page range used in pagination control
default_options:
page_name: page # page query parameter name
sort_field_name: sort # sort field query parameter name
sort_direction_name: direction # sort direction query parameter name
distinct: true # ensure distinct results, useful when ORM queries are using GROUP BY statements
template:
pagination: ::Pagination\twitter_bootstrap_v3_pagination.html.twig # sliding pagination controls template
sortable: ::Pagination\sortable_link.html.twig # sort link template
我已经在控制器和模板中转储了分页对象。每次参数都在那里（方向= asc 或 desc）时，url 中有类似的内容：
?sort=a.id&direction=desc&page=1
但如果我点击链接改变方向：什么都没有改变！！
我相信 knp 分页有一个错误！或者我很愚蠢；）
如果有人可以帮助我，我会很高兴！
