Structured Field Content
With the syntax for Kirby content files it is very easy to structure any kind of data for your templates. But the latest release of Kirby includes a brand new feature, which will give you even more data-structure-power – the YAML parser.
YAML is a very simple, human-readable structure syntax. It's actually quite similar to the Kirby content syntax and a perfect match. With YAML you will be able to nest structured data inside your content fields. Sounds weird, so let me just show you some examples to demonstrate how it works:
Example: nice addresses
If you are building a contact page and you've got just one address, so far you could simply structure the content like this for example…
Title: Contact ---- Street: 15 Sesamestreet ---- ZIP: 9210 ---- City: New York ---- Phone: 500-12131 ---- Email: email@example.com
But what happens, when you got more than just one address? Maybe your company has various offices all around the world or you are just very rich and you want to show off with the addresses of your houses on the Bahamas, New York, LA and in Monaco.
One way would be to add subpages for each address and then build a foreach loop with
$page->children() to display each address. But that would be quite an oversized solution for just showing more than one address.
You could also add multiple fields like this:
Street_a: 15 Sesamestreet … Street_b: 15 Sesamestreet … Street_c: 15 Sesamestreet etc.
but that would be very nasty.
With YAML syntax and the new YAML parser it becomes super easy to add more than just one address in one single field:
Title: Contact ---- Addresses: Monaco: Street: Rue de WTF 17 ZIP: 1112 City: Monaco Phone: 555-1234 Email: firstname.lastname@example.org New York: Street: 1212 Broadway ZIP: 4321 City: New York Phone: 666-4321 Email: email@example.com Bahamas: Street: At the beach ZIP: 9999 City: The capitol of the Bahamas Phone: 777-9999 Email: firstname.lastname@example.org
How to access data
In your template you can parse YAML like this:
<?php $addresses = yaml($page->addresses()) ?>
This will give you a nice associative array:
Array ( [Monaco] => Array ( [Street] => Rue de WTF 17 [ZIP] => 1112 [City] => Monaco [Phone] => 555-1234 [Email] => email@example.com ) [New York] => Array ( [Street] => 1212 Broadway [ZIP] => 4321 [City] => New York [Phone] => 666-4321 [Email] => firstname.lastname@example.org ) [Bahamas] => Array ( [Street] => At the beach [ZIP] => 9999 [City] => The capitol of the Bahamas [Phone] => 777-9999 [Email] => email@example.com ) )
a::show($array) to inspect the content of any array or object.
You can now use a simple foreach loop to build HTML for all addresses:
<?php foreach($addresses as $address): ?> <div class="address"> <?= $address['Street'] ?><br /> <?= $address['ZIP'] ?> <?= $address['City'] ?> … </div> <?php endforeach ?>
This works also great in connection with Microformats
As you can see this will give you a lot more control and structure for your content. It's not limited to addresses though:

…or whatever structured data you need!
