Link Generator

Summary

Link Generators are used to dynamically generate web-links for objects and are automatically called when objects are linked in document link editables, link document types and object link tags.

Additionally they are also enabling the preview tab for data objects.

Link generators are defined on class level, there are two ways to do this.

Either simply specify the class name ...

Link Generator Setup1

... or the name of a Symfony service (notice the prefix).

Link Generator Setup2

Link Generator Setup2a

<?php

namespace Website\LinkGenerator;

use Pimcore\Model\Document;
use Pimcore\Model\DataObject\ClassDefinition\LinkGeneratorInterface;
use Pimcore\Model\DataObject\Concrete;
use Pimcore\Model\Staticroute;

class NewsLinkGenerator implements LinkGeneratorInterface {

    public function generate(Concrete $object, array $params = []): string
    {
        $prefix = '/';
        if(isset($params['document']) && $params['document'] instanceof Document) {
            $prefix = $params['document']->getFullPath();
        }

        $staticRoute = Staticroute::getByName('news');
        $path = $staticRoute->assemble([
            'prefix' => $prefix,
            'text' => $object->getTitle(),
            'id' => $object->getId()
        ]);

        return $path;
    }
}

The link generator will receive the referenced object and additional data depending on the context. This would be the document (if embedded in a document), the object if embedded in an object including the tag or field definition as context.

Example Document

Link Generator Document

$d = Document\Link::getById(74);
echo($d->getHref());

would produce the following output

/testfolder/mylink/In%20enim%20justo_n8

Use in Views

<ul class="foo">
    <?php foreach($this->newsList as $news) { ?>
        <a href="<?= $this->pimcoreUrl(['object' => $news]); ?>"><?= $news->getTitle() ?></a>
    <?php } ?>
</ul>
