A set of multiple checkboxes which stores as an array of the checked values.

This class extends Fieldmanager_Options, which allows you to define options (values) via an array or via a dynamic Datasource, like posts, terms, or users.

1. Example 1: Basic List of Checkboxes

   add_action( 'fm_post_post', function() {
   	$fm = new Fieldmanager_Checkboxes( array(
   		'name' => 'demo-field',
   		'options' => array(
   			'red' => 'Red',
   			'green' => 'Green',
   			'blue' => 'Blue',
   		),
   	) );
   	$fm->add_meta_box( 'Checkboxes Demo', array( 'post' ) );
   } );

2. Example 2: Datasource Example

   This example will output a list of checkboxes with all users on the site. To provide the field with that data, it uses the User Datasource.

   add_action( 'fm_post_post', function() {
   	$fm = new Fieldmanager_Checkboxes( array(
   		'name' => 'demo-field',
   		'datasource' => new Fieldmanager_Datasource_User,
   	) );
   	$fm->add_meta_box( 'Checkboxes Demo', array( 'post' ) );
   } );
