🧱Reusable Block Extended: A cool WordPress plugin to extend Gutenberg reusable block feature

💙 Reusable blocks, an awesome Gutenberg feature

Reusable blocks is one of my favorite features in Gutenberg block editor.

This feature provides the ability to reuse contents across your whole website. What’s the difference between Reusable blocks and Regular Gutenberg blocks? Reusable blocks are stored in a custom post type called wp_block.

Reusable blocks also have their own admin screen – though it’s hidden for the moment, you can access it by URL:

You can see an example of that screen in the screenshot on the right.

Reusable blocks WP admin screen without plugin

This admin screen allows you to edit your reusable blocks from a single place, so they are all modified at the same time since all reusable blocks are synchronized.

Brilliant! But what about extending that feature? This is why I created Reusable Blocks Extended, which is now available on plugins repository:

(yeah, not so much ratings, the plugin was released earlier this morning ^^)

While being one of the Focus leads of WordPress 5.3, I finally found a couple of days to work on that shiny little plugin. Let’s see what’s in the box.

🔎 Introducing my advanced Admin screen for Gutenberg reusable blocks

Reusable blocks admin menu

First, I started by making the Reusable Block Admin screen accessible in WordPress Admin menu.

Then I extended the corresponding screen, by adding some columns:

  • Title of the reusable block, with native features like editing, trash and export tool
  • Used in: for each reusable block, get the list of all Posts that are using it. Very useful to clean up unused Reusable blocks and to see how many Posts will be modified when you are doing some changes on a reusable block.
  • Usage: for each reusable block, get:
    • A custom shortcode to use your reusable block everywhere, even on Posts that don’t use the block editor!
    • A custom PHP function to implement your reusable block in your theme files/templates.
    • A HTML preview to see what your block looks like. This is an experimental feature and it doesn’t work with all themes (for example it works well on Twenty Twenty or Twenty Nineteen, but not on Twenty Sixteen).
    • The date the block was last modified.

🛠 Custom PHP functions to use Gutenberg Reusable blocks in your theme/plugins

The plugin provides two functions to use your reusable blocks anywhere you need to, like in your theme or plugins:

reblex_display_block( $id ) where $id is the ID of your Reusable Block. This function will display/echo your reusable block.

reblex_get_block( $id ) where $id is the ID of your Reusable Block. This function will return the content of your reusable block.
Example: $my_block = reblex_get_block( 64 ) will put the content of Reusable block with ID 64 into $my_block PHP variable.

On Reusable Blocks Admin screen, you’ll get a pre-filled PHP snippet for each block:

🧷 Custom Shortcode to implement Reusable blocks in your theme/plugins

A shortcode is also available. will display the reusable block with ID 69.

For each reusable block, you can get a custom shortcode on Reusable blocks Admin screen:

It will provide the same feature than reblex_display_block() PHP function, but available to non-developers. This shortcode is very useful to integrate reusable blocks into Post types that are not using Gutenberg or in other plugin’s TinyMCE fields.

For example, here is an implementation of a reusable block into Gravity Forms confirmation message:

🔌 Implement Gutenberg Reusable Blocks using Widgets

The plugin also provides a dedicated widget to add Reusable blocks in your widget areas. Just choose the name of your block in the list and it will be displayed on your website!

👇 Last but not least

All your reusable blocks are also listed on your WordPress Admin Dashboard, with a link to the Reusable block screen:

Hello.. j’ai vu que sur le site de ma femme .. le plugin lancais une alerte de compatibilité

le : $( window ).load( function() {
et deprecieé.
j’ai corrigé chez moi avec ” $(window).on(“load”, function (e) {“

Do you plan to put the plugin on GitHub?

I would be interesting to discuss performance and Polylang compatibility.

Salut Jean-Baptiste,
tu a supporté et sauvé mon travail avec ton plugin! – You are my hero: Starting to build a culture website I had been looking for weeks for a way to use my self-made block patterns on the pages and posts of the site. Found the plugin BlockMeister and could then build patterns which however were not listed in the block pattern menue, so couldn’t be inserted. Only after installing your plugin I could use my patterns – either by defining them as reusable blocks and converting them into patterns with your plugin or – suddenly it worked! – by saving them directly as block patterns. – So definitely you know what you are doing inside the WordPress machinery! Merci beaucoup pour ton travail!
Only one question (I didn’t find any answers online): Why do some patterns (with me: just a 2 columns infobox for posts) remain unavailable for inserting? – Good luck + bonne chance, Achim
