<h4>Features</h4>
<p><strong>Dynamic Content</strong> — 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.</p>
<p><strong>Personalization</strong> — 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.</p>
<p><strong>Visibility Control</strong> — 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.</p>
<p><strong>Dynamic CSS Classes</strong> — Inject CSS classes into any block based on live data. Style blocks differently for administrators vs. guests, published vs. draft posts, and more.</p>
<p><strong>20+ Built-in Filters</strong> — 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>.</p>
<p><strong>Custom Fields</strong> — 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.</p>
<p><strong>Full Expression Language</strong> — Arithmetic, comparison, ternary, logical operators, string interpolation, and bracket access. All evaluated server-side with zero frontend JavaScript.</p>
<p><strong>In-Editor Autocomplete</strong> — Typing <code>{{</code> triggers smart autocomplete with categorized suggestions, icons, and live previews.</p>
<p><strong>Extensible</strong> — Register custom data roots, custom filters, and custom autocomplete suggestions via WordPress hooks and JavaScript filters.</p>

<h4>How It Works</h4>
<p>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.</p>
<pre><code>{{ post.title }}
{{ user.name | default "Guest" }}
{{ post.date | date "F j, Y" }}
{{ user.is_logged_in ? "Welcome back!" : "Hello, visitor!" }}
</code></pre>
<p>Expressions are rendered as interactive chips in the editor and resolved server-side on every page render. No JavaScript runs on the frontend.</p>

Vector Expressions

Embed dynamic expressions in the Gutenberg block editor to personalize content and control block visibility.

<p>Block Logic adds a “Block Logic” field to the “Advanced” section of the block editor (i.e Gutenberg), that lets you show or hide any block based on conditions. You can use WordPress’ <a href="https://codex.wordpress.org/Conditional_Tags" rel="nofollow ugc">Conditional Tags</a> or any general PHP code.</p>
<h3>Show or hide blocks based on</h3>
<ul>
<li>User role</li>
<li>User login status</li>
<li>Post status</li>
<li>Date and time</li>
<li>The result of a custom PHP function</li>
</ul>
<h3>Features</h3>
<ul>
<li>Show or hide any block using conditions</li>
<li>Combine conditions with “and” or “or” operators. See FAQ Writing Logic Code</li>
<li>Full flexibility: use any condition you want (you can extend base functionality with filters)</li>
</ul>
<h3>Limitations</h3>
<p>Does not work with the Classic Block, Widget Block or Widget Area Block [‘core/freeform’, ‘core/legacy-widget’, ‘core/widget-area’], as the those blocks do not support block attributes. Does also not work with the HTML Block [‘core/html’] inside the Widget Screen, as this one also does not support block attributes there.</p>
<h3>Configuration</h3>
<p>Just activate the plugin. The “Block Logic” textbox will then appear in the “Advanced” section of the Gutenberg editor.</p>
<h3>Breaking changes since 2.0.0</h3>
<p>Since version 2.0.0 the code does not get eval’d directly, but there is a whitelist of allowed functions that can be extended via a filter.</p>
<h3>Upgrade Notice</h3>
<p>When upgrading to version 2.x you will need to update your logic. No <code>return</code> is allowed anymore and no semicolons in code as only expressions are evaluated. See FAQ Section <strong>Writing Logic Code</strong>.</p>
