Quick Edit Deletes Book Meta Data

Whenever a Book is updated using the Quick Edit feature all the book meta data is erased (Prices, Publisher, etc.). I’ve patched this so can you all add it to the core. Thanks!

Go to file: /wp-content/plugins/mybooktable/includes/metaboxes.php
Edit Line 488

if((defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) || get_post_status($post_id) == 'auto-draft') { return; }

should be changed to:

if((defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) || !isset($_REQUEST['mbt_nonce']) || !wp_verify_nonce($_REQUEST['mbt_nonce'], plugin_basename(__FILE__))){return;}

Hope that helps
