Previous Question Next Question

Creating a custom block for the WordPress block editor involves using JavaScript, specifically React, to define the block's behavior and appearance. You'll typically use the `@wordpress/scripts` package to streamline the development process.

<!-- BEGIN COPY / PASTE -->
    // Register a new block type
    wp.blocks.registerBlockType('my-plugin/my-custom-block', {
      title: 'My Custom Block',
      icon: 'smiley',
      category: 'common',
      edit: function(props) {
        return wp.element.createElement('p', {}, 'Hello, World!');
      },
      save: function(props) {
        return wp.element.createElement('p', {}, 'Hello, World!');
      }
    });
    <!-- END COPY / PASTE -->

Additional Comment:

Ensure you have Node.js and npm installed to use the `@wordpress/scripts` package.
Run `npx @wordpress/create-block my-custom-block` to scaffold a new block plugin.
Customize the `edit` and `save` functions to define how your block appears in the editor and on the front end.
Use WordPress's built-in components and hooks for enhanced functionality.
