Adds a meta box to the new/edit post screen (for any post type), and saves data to post meta.

Action

fm_post_{post_type}

Fieldmanager_Field::add_meta_box()

1. Example 1: Basic Meta Box

   Note that in this example, we're hooking into the action fm_post_post, because we're adding fields to the post post type. If we were adding fields to a custom post type, e.g. event, you would hook into fm_post_event, and the second argument you would add to add_meta_box() would also be 'event'.

   add_action( 'fm_post_post', function() {
   	$fm = new Fieldmanager_TextField( array(
   		'name' => 'demo',
   	) );
   	$fm->add_meta_box( 'Basic Field', 'post' );
   } );

2. Example 2: Add a meta box to two post types

   Here, we're adding the same field to two post types (sponsor and attendee). In order to do so, we've hooked into both the fm_post_sponsor and fm_post_attendee actions, and we've added the meta box to both post types in the add_meta_box() method call.

   function my_basic_field() {
   	$fm = new Fieldmanager_TextField( array(
   		'name' => 'job_title',
   	) );
   	$fm->add_meta_box( 'Job Title', array( 'sponsor', 'attendee' ) );
   }
   add_action( 'fm_post_sponsor', 'my_basic_field' );
   add_action( 'fm_post_attendee', 'my_basic_field' );
