Vdlp.Sitemap

This plugin allows developers to create a sitemap.xml using a sitemap definition generator.

Requirements

• PHP 8.0.2 or higher
• Supports October CMS 3.x only

Usage

Sitemap definitions generator

To generate sitemap items you can create your own sitemap definition generator.

Example:

final class DefinitionGenerator implements Contracts\DefinitionGenerator
{
    public function getDefinitions(): Definitions
    {
        $definitions = new Definitions();

        for ($i = 0; $i < 100; $i++) {
            $definitions->addItem(
                (new Definition)->setModifiedAt(Carbon::now())
                    ->setPriority(1)
                    ->setUrl('example.com/page/' . $i)
                    ->setChangeFrequency(Definition::CHANGE_FREQUENCY_ALWAYS)
            );
        }

        return $definitions;
    }
}

Register your generator in the boot method of your plugin class:

Event::listen(Contracts\SitemapGenerator::GENERATE_EVENT, static function(): DefinitionGenerator {
    return new DefinitionGenerator();
});

You can also register multiple generators:

Event::listen(Contracts\SitemapGenerator::GENERATE_EVENT, static function(): array {
    return [
        new DefinitionGeneratorOne(),
        new DefinitionGeneratorTwo(),
        // ..
    ];
});

Invalidate sitemap cache

You can fire an event to invalidate the sitemap cache

Event::fire(Contracts\SitemapGenerator::INVALIDATE_CACHE_EVENT);

Or resolve the generator instance and use the invalidate cache method

/** @var SitemapGenerator $sitemapGenerator */
$sitemapGenerator = resolve(Contracts\SitemapGenerator::class);
$sitemapGenerator->invalidateCache();

Update / Add / Delete definitions in cache

First resolve the sitemap generator

/** @var SitemapGenerator $sitemapGenerator */
$sitemapGenerator = resolve(Contracts\SitemapGenerator::class);

Add definitions

$sitemapGenerator->addDefinition(
    (new Definition())
        ->setUrl('example.com/new-url')
        ->setModifiedAt(Carbon::now())
        ->setChangeFrequency(Definition::CHANGE_FREQUENCY_YEARLY)
        ->setPriority(5)
);

Update definitions

Note, definitions are updated by their URL.

$sitemapGenerator->updateDefinition(
    (new Definition())
        ->setUrl('example.com/page/1')
        ->setModifiedAt(Carbon::parse('1900-10-10'))
        ->setPriority(7)
        ->setChangeFrequency(Definition::CHANGE_FREQUENCY_HOURLY),
    'example.com/page/0' // (optional) specify the url to update in cache, when old url is null the definition url will be used.
);

Update or add definitions

$sitemapGenerator->updateOrAddDefinition(
    (new Definition())
        ->setUrl('example.com/create-or-add')
        ->setModifiedAt(Carbon::now())
        ->setChangeFrequency(Definition::CHANGE_FREQUENCY_YEARLY)
        ->setPriority(5),
    null // (optional) specify the url to update in cache, when old url is null the definition url will be used.
);

Delete definitions

$sitemapGenerator->deleteDefinition('example.com/new-url');

Exclude URLs from sitemap

Event::listen(SitemapGenerator::EXCLUDE_URLS_EVENT, static function (): array {
    return [
        'example.com/page/1',
    ];
});

Configuration

Add the plugin configuration to your config folder:

php artisan vendor:publish --provider="Vdlp\Sitemap\ServiceProvider" --tag="config"

You can change the amount of seconds the sitemap is cached in your .env file. You can also cache the sitemap forever.

VDLP_SITEMAP_CACHE_TIME=3600
VDLP_SITEMAP_CACHE_FOREVER=false

ConfigResolver

Optionally you can override how the sitemap config should be resolved by giving your own ConfigResolver implementation in the config file. This can be useful for multisite projects, where the sitemap should be cached per domain.

use Illuminate\Contracts\Config\Repository;
use Illuminate\Http\Request;
use Vdlp\Sitemap\Classes\Contracts\ConfigResolver;
use Vdlp\Sitemap\Classes\Dto\SitemapConfig;

final class MultisiteConfigResolver implements ConfigResolver
{
    public function __construct(private Repository $config, private Request $request)
    {
    }

    public function getConfig(): SitemapConfig
    {
        $domain = $this->request->getHost();

        return new SitemapConfig(
            'vdlp_sitemap_cache_' . $domain,
            'vdlp_sitemap_definitions_' . $domain,
            sprintf('vdlp/sitemap/sitemap_%s.xml', $domain),
            (int) $this->config->get('sitemap.cache_time', 3600),
            (bool) $this->config->get('sitemap.cache_forever', false)
        );
    }
}
