You can use the plug-in provided function eo_get_events(). This is essentially a wrapper for get_posts(), and so is intended for ‘secondary’ loops. The plug-in specific arguments can also be given to a WP_Query object – in case you wanted to modify the main loop. (Related: When to use WP_query(), query_posts() and pre_get_posts ) $events = … Read more
Interesting question. Investigating it, I’ve found a [wp-hackers] thread by the same Dion Hulse which gives a bit more of information. First, a testing page with a simple link which will open another admin page in a thickbox. add_action(‘admin_menu’, ‘wpse_71437_admin_submenu’); function wpse_71437_admin_submenu() { add_menu_page( ‘TB’, ‘<span style=”color:#e57300;”>Thickbox</span>’, ‘edit_pages’, ‘open_hidden_page_in_thickbox’, ‘wpse_71437_submenu_page’, ”, // no icon 1 … Read more

As explained in my comment in the Question, the error is certainly in how the DROP TABLE is being performed. But answering to How does uninstalling WordPress plugins work?: If we do a register_uninstall_hook in our plugin, the callback is stored in the option uninstall_plugins in /wp-includes/plugin.php. $uninstallable_plugins[plugin_basename($file)] = $callback; update_option(‘uninstall_plugins’, $uninstallable_plugins); In the PHPDoc … Read more
Use some kind of a Controller and combine the calls to both classes in one callback for each action. The controller should be responsible for the real assignation of business logic to an event (action), not some code outside of your classes. The basic point is: Your plugin controller should not alter data, only Models … Read more
