Structure

Structured data input, which stores data in a field as YAML.

The structure field makes it possible to add multiple complex entries to a field, which will be stored as YAML. A typical use case would be a list of addresses, team members or a restaurant menu.

Example

fields:
  addresses:
    label: Addresses
    type: structure
    fields:
      street:
        label: Street
        type: text
      zip:
        label: ZIP
        type: text
      city:
        label: City
        type: text

Such a structure will be stored in the content file like this:

addresses:
-
  street: Rue de WTF 17
  zip:    1112
  city:   Monaco
-
  street: 1212 Broadway
  zip:    4321
  city:   New York
-
  street: At the beach
  zip:    9999
  city:   The capitol of the Bahamas

width string 1/1

Fields

You can define any number of fields and use the same field types listed:

Default values

You can set default values for structure fields which will prepopulate the field:

emails:
    label: Emails
    type: structure
    default:
      - email: bastian@getkirby.com
      - email: lukas@getkirby.com
      - email: nico@getkirby.com
      - email: sonja@getkirby.com
    fields:
      email:
        label: Email
        type: email

Table columns

You can define the columns that are shown in the table. This is especially useful if you have a lot of fields in your structure and you don't want to show them all on first sight, but still keep them editable. Columns can also change the text alignment, set a custom width and define a before and after text that will be prepended or appended to the value.

Option Value Description
width 1/2, 1/3, 1/4, 2/3, 3/4 (any fraction since v3.2.0) Set width of column
align left, center, right Set text alignment
before string Set text to prepend value
after string Set text to append value

Example

fields:
    holidays:
        type: structure
        columns:
            title:
                width: 1/4
            images:
                width: 1/2
            price:
                width: 1/4
                align: right
                after: "USD"
        fields:
            title:
                type: text
            images:
                type: files
            description:
                type: textarea
            price:
                type: number
Since 3.2.0

Structure columns can be set to any fraction and will be automatically calculated into the right width.

fields: 
  mystructure: 
    label: Structure
    type: structure
    columns: 
      title: 
        width: 3/5      
      images: 
        width: 1/5
      price: 
        width: 1/10
    fields: 
      title: 
        label: A
        type: text
      images: 
        label: B
        type: text
      price: 
        label: C
        type: text

Hide toggle field text in preview

Since 3.3.0

When using toggle fields within structures, displaying the field's text in the preview can sometimes look cluttered. You can hide the text with the text option in the columns' definition.

fields:
  structure:
    columns:
      a:
        text: false
      b:
        text: false
    fields:
      a:
        type: toggle
      b:
        type: toggle
        text: this is some long text

Preview of fields in the table

The structure field tries to create the best possible preview for the field in its table view. If you are using fields provided by a plugin in the structure field, the preview of these can be customized with a field preview extension.

How to use in templates/snippets

To access a structure field in your templates, you can use the yaml() and toStructure() methods.

Let's say we wanted to render the holidays structure field example from above in a template:

<?php 
// using the `toStructure()` method, we create a structure collection
$items = $page->holidays()->toStructure();
// we can then loop through the entries and render the individual fields
foreach ($items as $item): ?>
  <h2><?= $item->title()->html() ?></h2>
  <?php foreach ($item->images()->toFiles() as $image): ?>
    <img src="<?= $image->crop(400)->url() ?>">
  <?php endforeach ?>
  <p><?= $item->price() ?></p>
<?php endforeach ?>
