What is WordPress Twenty Twenty-Three?

The WordPress Twenty Twenty-Three theme is a block-based theme designed to leverage the full potential of the Gutenberg editor.

The theme supports full site editing (FSE), making it easier than ever to customize layouts, templates, and blocks.

Why Develop Custom Blocks in Twenty Twenty-Three?

Custom blocks allow you to:

  • Tailor content: Create specific layouts and functionalities that align with your unique design and business needs.
  • Enhance usability: Simplify the content editing process for non-technical users by providing pre-designed block options.
  • Improve site performance: Use lightweight, custom-designed blocks instead of relying on bloated plugins.

Prerequisites for Custom Block Development

Before diving into custom block development, ensure you have the following:

  • A local WordPress development environment (e.g., Local by Flywheel or XAMPP).
  • Node.js and npm installed for building and managing block dependencies.
  • Basic knowledge of JavaScript, React, and WordPress development.
  • The Twenty Twenty-Three theme activated on your WordPress site.

Setting Up Your Environment for Custom Block Development

1. Install the Required Tools

To develop custom blocks, you’ll need:

  • WordPress Scripts: Install the @wordpress/scripts package to streamline your development process: npm install @wordpress/scripts --save-dev

2. Create a Plugin for Your Custom Blocks

Custom blocks are typically developed as plugins. Create a new folder in the wp-content/plugins directory, and add a PHP file to initialize your plugin. For example:

<?php
/*
Plugin Name: Custom Blocks for Twenty Twenty-Three
Description: A plugin for custom block development in the Twenty Twenty-Three theme.
Version: 1.0
Author: Your Name
*/

// Register block assets.
function register_custom_blocks() {
    wp_register_script(
        'custom-blocks-script',
        plugins_url( 'build/index.js', __FILE__ ),
        [ 'wp-blocks', 'wp-element', 'wp-editor' ],
        filemtime( plugin_dir_path( __FILE__ ) . 'build/index.js' )
    );

    register_block_type( 'custom-blocks/example', [
        'editor_script' => 'custom-blocks-script',
    ]);
}
add_action( 'init', 'register_custom_blocks' );

3. Build the Block

Inside your plugin folder, create the following structure:

custom-blocks/
|-- src/
|   |-- index.js
|-- build/
|-- package.json
|-- webpack.config.js

Edit src/index.js to define your block:

import { registerBlockType } from '@wordpress/blocks';
import { RichText } from '@wordpress/block-editor';

registerBlockType('custom-blocks/example', {
    title: 'Example Block',
    icon: 'smiley',
    category: 'common',
    attributes: {
        content: {
            type: 'string',
            source: 'html',
            selector: 'p',
        },
    },
    edit: ({ attributes, setAttributes }) => {
        const onChangeContent = (content) => setAttributes({ content });

        return (
            <RichText
                tagName="p"
                value={attributes.content}
                onChange={onChangeContent}
            />
        );
    },
    save: ({ attributes }) => {
        return <RichText.Content tagName="p" value={attributes.content} />;
    },
});

4. Compile Your Block

Use the following command to build your block:

npx wp-scripts build

5. Activate the Plugin

Activate your plugin from the WordPress dashboard to see your custom block in action.
