ACF { Data Selector Field

Adds a 'Data Selector' field type for the Advanced Custom Fields WordPress plugin.

---

Overview

This add-on adds a Data Selector field type to the Advanced Custom Fields plugin for version 4 and up. This field allows you to select data from customisable data sources using the relationship format.

Data sources can be registered using one of the following formats:

add_action('acf_data_selector/data', function($data) {

	// basic array
	$data['countries'] = array(
		'label' => 'Countries',
		'data' => array(
			'US' => 'United States',
			'UK' => 'United Kingdom'
		)
	);

	// complex array
	$data['rooms'] = array(
		'label' => 'Rooms',
		'data' => array(
			'101' => array(
				'label' => 'Meeting Room',
				'room_number' => '101',
				'floor' => '1'
			),
			'102' => array(
				'label' => 'Stock Room',
				'room_number' => '102',
				'floor' => '1'
			),
			'202' => array(
				'label' => 'Manager Room 1',
				'room_number' => '202',
				'floor' => '2'
			),
		)
	);

	// json array
	$data['regions'] = array(
		'label' => 'Regions',
		'data' => json_decode(file_get_contents('/data/regions.json'), TRUE)
	);

	return $data;

});

When using the basic array format the array value is used as the field label. However when using the complex array format be sure to set a label item.

When using the complex array format, calling get_field() will return the entire array for any given key, this means that any additional data we add into the array (room_number and floor in the example above) will be returned.
