Create a Meta Box

To add your own meta boxes, use the 'cmb_meta_boxes' filter to add your own meta box to the array of meta boxes.

Each meta box can be created by passing an array of setting. See available arguments listed below.

Available Args

• id (string) (optional) HTML 'id' attribute of the meta box. Constructed from title, if omitted.
• title (string) (required) Title of the edit screen section, visible to user
• fields (array) (required) An array of fields that will be added to the meta box.
• pages (string/array) (required) The type of Write screen on which to show the meta box (eg 'post', 'page', 'attachment'). Also accepts an array of post types.
• show_on (array) (optional) Further restrict where a meta box is shown. An array of key => value where key is what you are restricting by. Available restrictions are id and page-template. ID expects a numeric value or array of values. Page Template expects a string; the filename of the template.
• hide_on (array) (optional) Same as show_on, but allows you to hide by page template or post ID.
• context (string) (optional) The part of the page where the edit screen section should be shown ('normal', 'advanced', or 'side'). Default: 'advanced'
• priority (string) (optional) The priority within the context where the boxes should show ('high', 'core', 'default' or 'low')
• desc (string) (optional) Meta box description. Displayed as first item in meta box, above fields.

Example Code

add_filter( 'cmb_meta_boxes', 'cmb_sample_metaboxes' );

function cmb_sample_metaboxes( array $meta_boxes ) {
	
	$meta_boxes[] = array(
		'title'    => 'CMB Test - all fields',
		'pages'    => 'page',
		'show_on'  => array( 'id' => array( 1 ) ),
		'hide_on'  => array( 'page-template' => array( 'test-page-template.php' ) ),
		'context'  => 'normal',
		'priority' => 'high',
		'fields'   => $fields, // an array of fields - see individual field 
		'desc'     => 'This is the meta box description.',
