I had created plugin named DailyCostPlugin and initiate register_post_type function to create custom post named Daily Cost.I want to add Meta box named Daily Cost Details by add_action add_action( 'admin_init',array( $this, create_meta_cost_box' )); it goes into the function create_meta_cost_box but did not display metabox named Daily Cost Details, also it did not goto function named display_cost_box called in the add_meta_box. Here is code
<?php
