If you edit your wp-config.php file you can preload these FTP settings as constants read by WordPress. Keep in mind, on a shared host, you should be mindful of possible security implications. See Editing wp-config.php for more information. Your settings will vary, but these work for me and my hosting setup. I’ve included some of … Read more
I don’t think get_categories() is the best option for you in this case because it returns a string with all the categories listed as anchor tags, fine for displaying, but not great for figuring out in code what the categories are. Ok, so the first thing you need to do is grab the product/post object … Read more

Filters and actions are both assigned to hooks. Functions assigned to hooks are stored in global $wp_filter variable. So all you have to do is to print_r it. print_r($GLOBALS[‘wp_filter’]); PS. add_action function makes a add_filter call. And the latter does $wp_filter[$tag][$priority][$idx]. NOTE: you can directly add this code in functions.php, and you will see a … Read more

It also provides the same interface as this website (the toolbar, and live preview) – however, currently only for comments and bbPress forums (if enabled).
