<h4>Features</h4>
Dynamic Content — Insert live data into any block using a simple template syntax: <code>{{ post.title }}</code>, <code>{{ user.name }}</code>, <code>{{ site.name }}</code>. No shortcodes, no PHP templates, no code.
Personalization — Greet visitors by name, show role-specific content, or display custom messages based on login status. Expressions are evaluated server-side on every page load.
Visibility Control — Show or hide any Gutenberg block based on conditions. Display content only for logged-in users, specific roles, or specific post states — all configured from the block sidebar.
Dynamic CSS Classes — Inject CSS classes into any block based on live data. Style blocks differently for administrators vs. guests, published vs. draft posts, and more.
20+ Built-in Filters — Transform values with chainable pipes: <code>upper</code>, <code>lower</code>, <code>truncate</code>, <code>date</code>, <code>default</code>, <code>match</code>, <code>replace</code>, <code>kebab</code>, and more. Chain them: <code>{{ post.title | upper | truncate 20 }}</code>.
Custom Fields — Access any post or user meta with <code>post.meta.my_field</code> or <code>user.meta.my_field</code>. Sensitive keys are blocked by default.
Full Expression Language — Arithmetic, comparison, ternary, logical operators, string interpolation, and bracket access. All evaluated server-side with zero frontend JavaScript.
In-Editor Autocomplete — Typing <code>{{</code> triggers smart autocomplete with categorized suggestions, icons, and live previews.
Extensible — Register custom data roots, custom filters, and custom autocomplete suggestions via WordPress hooks and JavaScript filters.

<h4>How It Works</h4>
Add an expression to any block’s text content by typing <code>{{</code> and selecting your expression from the autocomplete menu. The plugin will automatically format it as an expression chip.
<pre><code>{{ post.title }}
{{ user.name | default "Guest" }}
{{ post.date | date "F j, Y" }}
{{ user.is_logged_in ? "Welcome back!" : "Hello, visitor!" }}
</code></pre>
Expressions are rendered as interactive chips in the editor and resolved server-side on every page render. No JavaScript runs on the frontend.

Have you ever used WordPress’ new block editor Gutenberg and wished for a way to influence, when and to whom blocks are shown? We’ve been in this situation, that’s why we came up with Block Control. This nifty little plugin allows you to control, whether a block should be displayed under certain circumstances or not. And that’s of course true for both WordPress’ default blocks and blocks added by third-party plugins.
You can hide blocks based on:
<ul>
<li>Device types (desktop, mobile, screen reader)</li>
<li>Login status</li>
<li>Date (start and end date)</li>
<li>User roles</li>
<li>Page types</li>
<li>Posts of the current post type</li>
<li>Page number in numbered pages (in archives and search results)</li>
</ul>
Additionally, you can set an inline formatting to display certain text only for screen readers.

I've used this plugins on two websites now. It works just great. The visibility option for different devices is very useful.

It works just smoothly

Lovely helper plugin lets you select, if you need to be logged in to see a block in a post or page and whether it should be hidden on certain devices.

Currently the plugin description may be a little vague ("it does what?") but the plugin works right out of the box and may be for many a smart solution for a simple task. 

Well done, Matthias and Simon. 👏🏻

Nice little helper plugin

Block Control allows you to take control of all the blocks on your website. Tailor a unique experience for your visitors.
