Array Fieldtype
Manage data in a key:value array format.
Overview#
This fieldtype is used to manage key: value array data in the right situation. It's used for situations when there is data you would like to stay grouped together because there's only one set and you don't want to use loops.
If you'd like to have lists of this type of data, you might want to use a grid or replicator field.
Modes#
The screenshot above depicts the three modes you can choose from. Two for when you know there is a fixed set of keys (keyed/single), and one for when you don't (dynamic).
Keyed Mode#
The first field contains pre-defined keys. This will give the user a stricter input. They can only enter the values for the specified keys, and they cannot be reordered.
address:
type: array
keys:
street: Street
city: City
country: Country
The keys can be specified with or without labels. The snippet above (and what's shown in the screenshot) uses labels.
The following is an example of just keys. When using this syntax, the key and the label will be identical.
keys:
- street
- city
- country
Single Mode#
Exactly the same restrictions and setup as keyed mode, except the user can only manage an array one item at a time, using a select box to switch between keys.
Dynamic Mode#
The second field contains no pre-defined keys. This will allow the user to define them on the fly and re-arrange them.
address:
type: array
Column headings can be set with value_header & key_header.
value_header: Type of Bacon
key_header: Why is it awesome?
Expanded storage (expand)#
By default, array data is stored as a YAML mapping (key: value). Set expand: true to store it as an ordered list of objects instead:
# expand: false (default)
sizes:
"42": Medium
"7": Small
# expand: true
sizes:
-
key: "42"
value: Medium
-
key: "7"
value: Small
Use expanded storage when keys need to be numbers (YAML mappings treat numeric keys oddly), when you rely on explicit row order (for example with the Eloquent Driver and MySQL, where key order on associative arrays is not preserved), or when you edit raw YAML and want unambiguous structure.
inventory:
type: array
expand: true
keys:
sku: SKU
qty: Quantity
Augmentation still exposes the field as a normal key/value structure for templates and Antlers, so {{ inventory:sku }} and nested variable syntax behave the same whether expand is on or off.
Data Structure#
In the example above, the keyed mode and dynamic mode would save the exact same data (unless expanded storage is enabled—in that case the same logical keys are stored as a list of key / value objects).
address:
street: 221B Baker Street
city: London
country: England
Single mode will only save data if it has been entered by the user.
address:
England: '221 Baker Street, London'
Templating#
This fieldtype is not augmented.
You can use basic array access, nested variables, or the foreach tag to loop through all of the keys. All three of the following methods are equivalent.
// Array access
{{ address }}
{{ street }} {{ city }} {{ country }}
{{ /address }}
// Nested variables
{{ address:street }} {{ address:city }} {{ address:country }}
// Foreach tag:
{{ foreach:address }}
{{ value }}
{{ /foreach:address }}
You can use basic array access or the @foreach directive to loop through all of the keys.
// Nested variables
{{ $address['street'] }}
{{ $address['city'] }}
{{ $address['country'] }}
// Using foreach
@foreach ($address as $key => $value)
{{ $key }}: {{ $value }}
@endforeach
Options
keys
Define keys when using keyed mode. Default: null.
mode
Determine which mode to use. Default: dynamic.
value_header
Value column heading displayed when using dynamic mode Default: Value.
key_header
Key column heading displayed when using dynamic mode Default: Key.
add_button
Add button text customization. Default: Add Row.
expand
Save the field as an ordered list of key / value objects instead of a flat YAML mapping. Enable when you need numeric keys, stable option order with database-backed content stores, or to avoid YAML limitations with certain key types. Default: false.
