wp_schedule_event takes a hook as parameter, not a function. Try: wp_schedule_event(time(), ‘daily’, ‘my_daily_event’); add_action(‘my_daily_event’, array(&$this, ‘my_widget_cron’)); if ( !wp_next_scheduled( ‘my_daily_event’ ) ) { wp_schedule_event(time(), ‘hourly’, ‘my_daily_event’) } If you remove the widget from the sidebar, the cron will still continue to run. You can run the following code (outside of the widget class) to clear … Read more
Use add_query_arg() to do this. Here’s a useful function if you need to get the current page URL (when get_permalink is inaccesible, like on Archives): function get_current_page_url() { $request = esc_url($_SERVER[“REQUEST_URI”]); $pageURL = (is_ssl() ? ‘https’ : ‘http’).’://’; if ($_SERVER[“SERVER_PORT”] != “80”) $pageURL .= $_SERVER[“SERVER_NAME”].”:”.$_SERVER[“SERVER_PORT”].$request; else $pageURL .= $_SERVER[“SERVER_NAME”].$request; if (false === strpos(get_option(‘home’), ‘://www.’)) $pageURL … Read more

Review the template hierarchy from the Codex to gain a better understanding of what files are read when. This will help you to understand what’s called in what situation (tag/category/front-page/etc). Content.php is never mentioned in the documentation as its not a part of the template hierarchy.
