I’ve seen posts and documentation online for how to get just the customer notes for an order, but no great ones for how to get all WooCommerce order notes. Here’s my solution for that: View the code on Gist. You just pass that function the order ID (post ID) for any order and it returns an […]
Using the Gravity Forms + Custom Post Types WordPress plugin to map your Gravity-Forms-generated posts to a custom post type is very handy, but I noticed that it doesn’t seem to work with file uploads.

If you want to get the file mime type for a remote file and you have its URL, the function below can be used. Example: If the remote file is a png image with a url of http://example.com/directory/image.png?ver=123, passing in that URL to this function would return image/png. View the code on Gist.

WordPress has a built in username_exists() function to check if a user exists by their username, but there isn’t a similar function for checking if a user exists by their user ID. I’ve seen posts online where folks suggest a way of doing that with a direct database query using $wpdb. While that works, the function […]
The functions below can be used to get the root domain of a WordPress site. If the site is a multisite network and you’re on http://www.site1.example.com/page-1/, calling km_get_root_domain() would return example.com for instance. It also works on single-site WP installations. View the code on Gist.
The code below can be used to get the URL of the main site in the WordPress Multisite Network: View the code on Gist.
CMB2 comes with default styles, but you may want to disable them if you’re outputting forms on the front end so they can be styled to match the rest of the site. Here’s how to disable CMB2 styles for all front end forms: View the code on Gist. Or if you’d rather prevent the CMB2 […]
