How to get CMB working within a plugin?

[Posh John]

I am in the process of moving my CPTs to a core functionality plugin (my first plugin yay!)

I am having trouble getting my metaboxes to work within my plugin - i'm using the CMB files.

Usually with my /lib/metabox folder inside my theme it works, but i can't figure out how to move all this to the plugin. When i was building my cpt within my theme i had this in my cpt file >

// Initialize the metabox class
add_action( 'init', 'be_initialize_cmb_meta_boxes', 9999 );
function be_initialize_cmb_meta_boxes() {
	if ( !class_exists( 'cmb_Meta_Box' ) ) {
		require_once(CHILD_DIR . '/lib/metabox/init.php');
	}
}

Now i am doing it from within my plugin, I tried changing the "require_once" line to the following >
require_once( plugin_dir_url(__file__) . 'lib/metabox/init.php' );

... but get the white screen of death! What am i doing wrong?

Figured it out!

For anyone that's interested, the "require_once" line should have been >

require_once( plugin_dir_path(__FILE__) . 'lib/metabox/init.php' );

Cool - i just built my first plugin 🙂
