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:
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 Beautiful Datepicker Field in WordPress Admin
In this tutorial I will show you how you can easily create a beautiful datepicker field just like on the screenshot below without any additional JavaScript libraries.
How to Handle Theme Updates from your Custom Server
My tutorial about configuring self-hosted plugin updates became quite popular so I decided to publish a similar tutorial related to WordPress themes.
The whole tutorial consists of two steps – in the first step we are going to configure our custom update server, in the second step – create a theme actually.
Meta Boxes Conditional Logic
In this tutorial I will explain you how to show or hide a field depending on a value of another field within a simple WordPress metabox.
Like this:
Add Custom Fields to a Taxonomy
In this tutorial I will show you step by step how to add a custom field to a custom taxonomy in WordPress. Of course, this method is going to work great for default taxonomies as well.
First of all I will show you how to do it without any plugins and then we will do the same with the help of my Simple Fields plugin, so you can see the difference.
Well, let’s take a look what we are going to create here.
And this is how it looks when you go edit a specific taxonomy term:
Create Custom Options Pages
WordPress custom settings pages are quite useful when you are developing a plugin or a theme. You will definitely need some place in admin area where users can configure your plugin and Settings API is perfect for that.
And yes, we are going to use Settings API which will help us creating our options pages. It was added in WordPress 2.7 only. I really doubt that you are using a WordPress version prior 2.7, but anyway I think I have to mention that.
Below is the screenshot of a settings page we are going to create in this tutorial. I decided to make it simple, so we have multiple fields – a text field and a checkbox.
