How to implement rel=prev and rel=next to Symfony2.3 pagination? - php

Question

I am using Symfony2.3 for my project and for pagination I am using KNP paginator Bundle.
I want to know that How I can implement rel=prev and rel=next in our page ?
My Controller :
<?php
namespace XXX\ABCBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use Symfony\Component\HttpFoundation\Session\Session;
use Doctrine\ORM\EntityManager;
/**
* author Siddharth Singh (siddharth.find#gmail.com)
*/
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);
}
}
Twig File :-
{% 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 %}
Thanks !

Accepted answer does not work because rel=prev and rel=next must be inside head tag.
I use this macros:
{% 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 %}
Inside a template usage looks like this:
{% import 'AppBundle::macros.html.twig' as macros %}
{% block head %}
{{ parent() }}
{{ macros.pagination_meta(entities) }}
{% endblock %}

You can do it by overriding default pagination template. Check Templates part of the official documentation:
https://github.com/KnpLabs/KnpPaginatorBundle/blob/master/Resources/doc/templates.md
for example:
Tell KnpPaginatorBundle to load your template for rendering pagination, add these lines of code to config.yml:
knp_paginator:
template:
pagination: YourBundle::pagination.html.twig
And copy default pagination template code to your template in src/YourBundle/Resources/views/pagination.html.twig. You can get the code here:
https://github.com/KnpLabs/KnpPaginatorBundle/blob/master/Resources/views/Pagination/sliding.html.twig
