How to Create Custom Blocks in WordPress for More Flexibility and Functionality

The WordPress block editor, also known as Gutenberg, provides a more visual and intuitive way to create and customize content compared to the classic editor. With blocks, you can easily add, rearrange and style various elements like paragraphs, images, buttons, and more without needing to know HTML or CSS.

WordPress comes with an extensive library of built-in blocks covering most common content needs. There are six main categories:

  1. Text blocks – for adding headings, paragraphs, lists, quotes, tables, and more. Format your text and create a clear content hierarchy.

  2. Media blocks – embed single images, galleries, video, audio and other media from your WordPress media library.

  3. Design blocks – insert separators, spacers, buttons, columns and other layout elements to organize and enhance your content.

  4. Widget blocks – add widgets like a search bar, latest posts, categories, and more anywhere on the page, not just sidebars and footers.

  5. Theme blocks – these are default blocks included with your theme like post title, post content, site logo, navigation menu, etc.

  6. Embed blocks – easily embed content from YouTube, Twitter, Spotify, and dozens of other sites by just pasting the URL – no manual embed code needed.

While this default set of blocks handles most situations, you may want to create your own custom WordPress blocks to add more advanced, unique functionality. Some examples could be:

  • Custom block templates that are pre-filled with your preferred placeholder content and settings
  • Branded content blocks like a call-to-action, testimonial, or product details
  • Integration with other plugins and APIs to fetch and display external data
  • Advanced layout and design options beyond the core formatting tools

Thankfully, WordPress allows developers to register their own custom blocks. There are two main approaches:

Method 1: Register Custom Gutenberg Blocks in functions.php

The first way is to use the register_block_type() function in your theme‘s functions.php file or a site-specific plugin. Here‘s an example that registers a custom "News" block with a paragraph and image:


add_action( ‘init‘, function() {
    $args = array(
        ‘public‘ => true,
        ‘label‘ => ‘News‘,
        ‘show_in_rest‘ => true,
        ‘template_lock‘ => ‘all‘,
        ‘template‘ => array(
            array( 
                ‘core/paragraph‘, 
                array(
                    ‘placeholder‘ => ‘Breaking News‘,
                ) 
            ),
            array( 
                ‘core/image‘,
                array(
                    ‘align‘ => ‘right‘,
                )
            ),
        ),
    );
    register_post_type( ‘news‘, $args );
} );

Let‘s break this down:
–register_post_type(): This function registers a new custom post type, in this case ‘news‘.

  • ‘public‘ => true: The block will be publicly queryable.
  • ‘label‘ => ‘News‘: This is the name of the block that will appear in the editor.
  • ‘show_in_rest‘ => true: The block will be available in the WordPress REST API. This is required for Gutenberg.
  • ‘template_lock‘ => ‘all‘: Prevents the custom block template from being edited. The template is "locked".
  • ‘template‘ : An array that defines the initial block template. Each block is defined in the form array( ‘blockname‘, array( / block settings / ) ).

For example, array( ‘core/paragraph‘, array( ‘placeholder‘ => ‘Breaking News‘ ) adds a paragraph block with placeholder text. array( ‘core/image‘, array( ‘align‘ => ‘right‘ ) adds an image block aligned to the right.

When you edit a post or page, your custom News block will appear with the pre-configured paragraph and right-aligned image fields ready to fill in.

The template functionality allows you to define custom block patterns that are ready to go. This can save time and keep content more consistent.

Method 2: Create a Dedicated Custom Blocks Plugin

The second method is to create a separate WordPress plugin for your custom blocks. This is ideal if you want to use the blocks on multiple sites.

To create the plugin:

  1. Go to your /wp-content/plugins directory and create a new folder for your plugin, e.g. custom-blocks.

  2. In that folder, create a main PHP file for your plugin named after the folder, e.g. custom-blocks.php

  3. Add this code to the file: 


/*
Plugin Name: My Custom Blocks
Description: Plugin for adding custom Gutenberg blocks
Version: 1.0
*/

add_action( ‘init‘, function() {


// Add block registration code here


});

  1. Between the add_action() tags is where you register your custom blocks, using the same code in Method 1.

  2. Go to your WordPress admin Plugins page. You should see "My Custom Blocks" listed. Click the "Activate" button.

  3. You can now add your custom blocks to any post or page!

Using Your Custom Blocks

To add a custom block to your content:

  1. Edit a post or page and click the plus (+) icon to add a new block
  2. Use the search bar to find your custom block by name
  3. Click on the block to insert it

Once inserted, you can:

  • Fill out any pre-defined template fields like a heading, paragraph, or image. Replace placeholders with your own content.
  • Use the toolbar and block settings side panel to further customize the block‘s appearance and settings. Options vary based on the block.
  • Drag and drop the block to rearrange its position on the page, or use the up/down arrows to move it.
  • If it‘s not part of a locked template, you can remove the block entirely.

Using custom blocks allows you to create more advanced page layouts and functionality than the default blocks provide. And by defining reusable templates or patterns, you can streamline the creation of common content types.

Get the Most Out of WordPress with Managed Hosting

To ensure peak performance and get the most out of WordPress, it‘s worth using a managed WordPress host. Hosts that specialize in WordPress offer:

  • Automatic core updates and security patches
  • One-click staging environments to safely test changes
  • Automatic daily backups
  • Caching and speed optimizations for faster load times
  • Expert WordPress support

So you can focus on building your site and creating custom blocks while they handle the technical details.

Whether you register custom blocks in your theme or create a dedicated plugin, custom blocks open up new opportunities in WordPress. You can craft advanced content sections, integrate with third-party data, and add interactive features.

Combined with the intuitive drag-and-drop block editor and a top-notch managed WordPress host, you have everything you need to build a unique, professional WordPress site. The only limit is your imagination.
