Content Representations
Content representations allow you to output the content in different formats. You can read more about them in the Kirby documentation.
1. Creating the template
For our image representation, let’s create a file default.png.php
in our /site/templates
directory. This file contains the template that will later be rendered to an image by Puppeteer.
It works just like writing a normal HTML template.
Content representations use the same name as its HTML counterpart. This means, if we want to create an image for all project
pages, our template name has to be project.png.php
.
2. Creating the Paparazzi controller
Paparazzi uses controllers to inject its logic in your templates. Let’s create a file with the same name as your template in our /site/controllers
directory.
<?php
use tobimori\Paparazzi\Controller;
return Controller::run(width: 1200, height: 630);
3. Adding content to the template
Now, let’s add some content to our template. We can use all the Kirby variables & helpers just like in a normal template.
Our example template could look something like this:
<h1><?= $page->title() ?></h1>
<img src="<?= $page->image()->url() ?>">
<?php foreach ($page->children()->listed() as $child): ?>
<h2><?= $child->title() ?></h2>
<p><?= $child->text()->excerpt(50) ?></p>
<?php endforeach ?>
4. Admire the result in your browser
We can now open our page in the browser, and simply add .png
to the URL. This will render our template to an image.
5. Usage with Kirby SEO (optional)
If you’re using my kirby-seo plugin, and you want to use the image as Open Graph image, you can use the programmatic defaults feature for that.
- Create a page model, e.g.
site/models/project.php
. You can read more about Page models in the Kirby Guide. - Add a
metaDefaults()
function that returns an array with the Open Graph image URL, like so:
<?php
use Kirby\Cms\Page;
class ProjectPage extends Page
{
public function metaDefaults()
{
return [
'og:image' => $this->url() . '.png'
];
}
}
Please note, that this will require kirby-seo v1.0.0 or higher.
