Sometimes you need to do some stuff when your WooCommerce product variation has been changed. Maybe only for a specific variation.

Primarily there are two JavaScript events that are triggered after a variation change.

I’ve been asked about how to do it probably a million times. The question is how to make the URLs of your custom post types (or WooCommerce products) to look like Pages.

For example how to have example.com/t-shirt/ instead of example.com/product/t-shirt/.

In this tutorial I am going to provide you a complete guide! As an example we are going to remove /product/ from WooCommerce product URLs. But before we begin I would like to warn you that you have to avoid it if possible, because it may slows down the overall performance of your website and you have to be extra-careful when assigning a specific slug for your posts.

Let’s assume, that you’re currently working on Site A and you need to get and display a post (or page or a custom post type – doesn’t matter) from Site B of your Multisite network.

How to do that?

I have a super-detailed tutorial about plugin sidebars on my blog. But there were described only some basic field types like TextControl, TextareaControl and ToggleControl.

What about something much more interesting? I mean when there were no Gutenberg years ago, I already created an image uploader field for WordPress meta boxes or options pages. What about creating a custom ImageControl component for Gutenberg sidebars right now?

In this tutorial I am going to show two methods how you can add additional user profile fields in WordPress admin area. In the first one we are not going to use any plugins at all, in the second one – we will do the same, but with the help of my Simple Fields plugin.

Let’s get started, I think. Here is what we are going to create:

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:

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.

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.
