README

This Symfony bundle allows you to easily generate a sitemapindex and one or multiple sitemap(s).

To Do Features

What needs to be done:

Generate the "sitemap provider last modified on datetime" which we need to show in the sitemapindex.

Usage

Installation

composer require jeroendesloovere/sitemap-bundle

Example: "How to create your custom sitemap?"

We need to notify Symfony that we have a new sitemap provider. Add the following somewhere in your services.yaml

services:
    App\SitemapProviders\NewsArticleSitemapProvider:
        tags:
            - { name: sitemap.provider }

When the SitemapGenerator needs to generate the sitemap(s), it will ask all SitemapProviders to fill in the items. Create something like the following in your app.

<?php

namespace App\SitemapProviders;

use JeroenDesloovere\SitemapBundle\Item\ChangeFrequency;
use JeroenDesloovere\SitemapBundle\Provider\SitemapProvider;
use JeroenDesloovere\SitemapBundle\Provider\SitemapProviderInterface;

class NewsArticleSitemapProvider extends SitemapProvider implements SitemapProviderInterface
{
    /** @var NewsArticleRepository */
    private $articleRepository;

    public function __construct(NewsArticleRepository $articleRepository)
    {
        $this->articleRepository = $articleRepository;

        // `NewsArticle::class` would even be better then just `NewsArticle`
        // because you can then use it with doctrine events.
        parent::__construct('NewsArticle');
    }

    public function createItems(): void
    {
        /** @var Article[] $articles */
        $articles = $this->articleRepository->findAll();
        foreach ($articles as $article) {
            $this->createItem('/nl/xxx/url-to-article', $article->getEditedOn(), ChangeFrequency::monthly());
        }
    }
}

You can now generate the sitemap(s) by executing:

bin/console sitemap:generate

Use a cronjob (f.e. every hour) to have up-to-date sitemaps.

OR if you want to use PHP

$this->getContainer()->get('sitemap.generator')->generate();

Example: You can overwrite the context

Problem

There is a known "bug" in symfony, that the context in console is always http://localhost, f.e.: when executing bin/console sitemap:generate. Read more about this on the Symfony website.

Solution

One of the two provided solutions is that you can solve the empty context by adding a CompilerPass in your code.

<?php

namespace App\Sitemap;

use App\Sitemap\DependencyInjection\Compiler\SitemapProviderPass;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpKernel\Bundle\Bundle;

class SitemapBundle extends Bundle
{
    public function build(ContainerBuilder $container)
    {
        $container->addCompilerPass(new SitemapProviderPass());
    }
}

<?php

namespace App\Sitemap\DependencyInjection\Compiler;

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;

class SitemapCompilerPass implements CompilerPassInterface
{
    public function process(ContainerBuilder $container): void
    {
        if (!$container->has('sitemap.generator')) {
            return;
        }

        $container->setParameter('router.request_context.host', 'www.mywebsite.com');
        $container->setParameter('router.request_context.scheme', 'http');
        $container->setParameter('router.request_context.base_url', '');
        $container->setParameter('asset.request_context.base_path', $container->getParameter('router.request_context.base_url'));
        $container->setParameter('asset.request_context.secure', true);
    }
}

Example: "How to use a Doctrine subscriber?"

Sometimes you want to fetch database changes from Doctrine events. The following code helps you doing that and regenerates the sitemaps.

    sitemap.subscriber:
        class: JeroenDesloovere\SitemapBundle\EventListener\SitemapSubscriber
        tags:
            - { name: doctrine.event_subscriber }
        arguments:
            - "@sitemap.providers"
            - "@sitemap.generator"

<?php

namespace JeroenDesloovere\SitemapBundle\EventListener;

use Doctrine\Common\EventSubscriber;
use Doctrine\Common\Persistence\Event\LifecycleEventArgs;
use Doctrine\ORM\Events;
use JeroenDesloovere\SitemapBundle\Generator\SitemapGenerator;
use JeroenDesloovere\SitemapBundle\Provider\SitemapProviders;

class SitemapSubscriber implements EventSubscriber
{
    /** @var SitemapGenerator */
    private $sitemapGenerator;

    /** @var SitemapProviders */
    private $sitemapProviders;

    public function __construct(SitemapProviders $sitemapProviders, SitemapGenerator $sitemapGenerator)
    {
        $this->sitemapProviders = $sitemapProviders;
        $this->sitemapGenerator = $sitemapGenerator;
    }

    public function getSubscribedEvents(): array
    {
        return [
            Events::postPersist,
            Events::postUpdate,
            Events::postRemove,
        ];
    }

    /**
     * @param LifecycleEventArgs $eventArgs
     * @throws \Exception
     */
    public function regenerate(LifecycleEventArgs $eventArgs): void
    {
        $entityClass = get_class($eventArgs->getObject());

        if ($this->sitemapProviders->exists($entityClass)) {
            $this->sitemapGenerator->regenerateForSitemapProvider($this->sitemapProviders->get($entityClass));
        }
    }

    public function postPersist(LifecycleEventArgs $eventArgs): void
    {
        $this->regenerate($eventArgs);
    }

    public function postRemove(LifecycleEventArgs $eventArgs): void
    {
        $this->regenerate($eventArgs);
    }

    public function postUpdate(LifecycleEventArgs $eventArgs): void
    {
        $this->regenerate($eventArgs);
    }
}

Documentation

The class is well documented inline. If you use a decent IDE you'll see that each method is documented with PHPDoc.
