Add Custom Fields to Comments

I already have plenty of tutorials about working with custom fields – a tutorial about creating custom meta boxes for posts, a tutorial about custom taxonomy term fields, a tutorial about options pages and even my own Simple Fields plugin intended to simplify the work with all that stuff. Now it is time to talk about meta boxes for comments.

The long story short let me show you what we are going to create:

create a custom metabox for WordPress comments

It is not a very difficult meta box, but I am just going to show you the process how it works, everything else is up to you. We are going to do it without any plugins first.

Sanitize Early, Escape Late, Always Validate

If you’re working with WordPress for a while, I am sure you’ve heard about such words like “sanitizing” or “escaping” or at least have seen in the code sanitize_text_field(), esc_html() or similar functions.

This tutorial is intended to sort this whole data validation thing out once and forever.

Create Orders Programmatically

In this tutorial we are going to dive deep into creating an order on your WooCommerce store completely via code. I already have a similar tutorial on my blog where we created a product programmatically.

First things first, you should know a very simple thing – yeah, orders is a WordPress custom post type and no, we can not use wp_insert_post() to create them. We have to use a CRUD layer for that. If it says nothing to you, please be patient, we’re going to dive into it in just a little bit.
