如何实现 rel=prev 和 rel=next to Symfony2.3 分页

Question

我正在使用Symfony2.3进行项目，对于分页，我正在使用KNP分页器捆绑包。我想知道我如何在我们的页面中实现 rel=prev 和 rel=next？

我的控制器 ：

<?php
namespace XXXABCBundleController;
use SymfonyBundleFrameworkBundleControllerController;
use SensioBundleFrameworkExtraBundleConfigurationRoute;
use SensioBundleFrameworkExtraBundleConfigurationTemplate;
use SymfonyComponentHttpFoundationSessionSession;
use DoctrineORMEntityManager;
/**
 * author Siddharth Singh ([e-mail])
 */
class ArcController extends Controller {
/**
 * @Route("/arch", name="_arch")
 * @Template()
 */
public function indexAction() {
        $em = $this->getDoctrine()->getEntityManager();
        $AArtEntity = $em->getRepository('XXXABCBundle:Arc')->findAll(array('updated'=>'DESC'));
        $paginator = $this->get('knp_paginator');
        $pagination = $paginator->paginate(
                $AArtEntity, $this->get('request')->query->get('page', 1)/* page number */, 10/* limit per page */
        );
    return array('article' => $pagination);
}
}

树枝文件 ：-

 {% extends 'XXXABCBundle::layout.html.twig' %}
 {% block body %}
            {% for artic in article %}
                    <div class="txt">
                        <p>{{artic.description|striptags|titletruncate(250)}}</p>
                    </div>
            {% endfor %}
            <div class="arcive_Paging">
                <ul class="ul_paging">
                    <span class="acitve">{{ knp_pagination_render(article) }}</span>
                </ul>
            </div>
{% endblock %}

谢谢！

接受的答案不起作用，因为rel=prev和rel=next必须在head标签内。

我使用此宏：

 {% macro pagination_meta(pagination) %}
    {% set total = pagination.totalItemCount %}
    {% set items_per_age = pagination.itemNumberPerPage %}
    {% set current = pagination.currentPageNumber %}
    {% set last = (total / items_per_age) | round(0, 'ceil') %}
    {% set page_parameter = pagination.paginatorOption('pageParameterName') %}
    {% if current != 1 %}
        <link rel="prev" href="{{ path(app.request.attributes.get('_route'), app.request.attributes.get('_route_params') | merge({ (page_parameter): (current - 1) })) }}" />
    {% endif %}
    {% if current != last %}
        <link rel="next" href="{{ path(app.request.attributes.get('_route'), app.request.attributes.get('_route_params') | merge({ (page_parameter): (current + 1) })) }}" />
    {% endif %}
{% endmacro %}

在模板内用法如下所示：

{% import 'AppBundle::macros.html.twig' as macros %}
{% block head %}
    {{ parent() }}
    {{ macros.pagination_meta(entities) }}
{% endblock %}

您可以通过覆盖默认分页模板来做到这一点。检查官方文档Templates部分内容：

https://github.com/KnpLabs/KnpPaginatorBundle/blob/master/Resources/doc/templates.md

例如：

告诉 KnpPaginatorBundle 加载模板以呈现分页，请将以下代码行添加到 config.yml：

knp_paginator:
    template:
        pagination: YourBundle::pagination.html.twig

并将默认分页模板代码复制到您的模板中 src/YourBundle/Resources/views/pagination.html.twig .您可以在此处获取代码：
