<p>RenderWhen for Blocks adds conditional visibility to every block in the WordPress block editor. Decide who sees what, and when, with a panel that reads exactly how you’d say it out loud:</p>
<blockquote>
<p><em>Show this block when the user is logged in.</em><br />
  <em>Show this block when the date is between March 1 and March 31.</em><br />
  <em>Show this block when the device is mobile.</em></p>
</blockquote>
<p>RenderWhen is built around two ideas that set it apart from other visibility plugins:</p>
<ul>
<li><strong>Server-side rendering only.</strong> When a block is hidden by a condition, it is not rendered into the page output at all. No CSS <code>display: none</code>, no DOM bloat, no leaked content in view-source. Search engines, screen readers, and your page weight all benefit.</li>
<li><strong>Public Conditions API.</strong> The three built-in conditions are registered through the same public API your plugin or theme can use to add your own. No hacks, no internal-only code paths.</li>
</ul>
<p>In the editor, a subtle dashed border marks every block that carries a visibility rule, so a rule-bearing block never disappears from the published page as a surprise. A “Preview as audience” sidebar lets you simulate a logged-out visitor, a specific role, or a different device class right in the editor — blocks whose rule would hide them fade out with a clear badge, no save-and-reload cycle required.</p>
<h4>Built-in conditions (v1.0)</h4>
<ul>
<li><strong>User state</strong> — show to logged-in users, logged-out users, or specific roles</li>
<li><strong>Date range</strong> — show between two datetimes, timezone-aware</li>
<li><strong>Device type</strong> — show on desktop, tablet, or mobile</li>
</ul>
<h4>Designed for</h4>
<ul>
<li>Agencies and freelancers building client sites who want a clean, predictable visibility tool</li>
<li>Developers who need an extension point, not another walled garden</li>
<li>Anyone who cares about page weight and SEO hygiene</li>
</ul>
<h4>What this plugin deliberately does NOT do</h4>
<p>It does one thing well rather than ten things adequately. Out of scope in v1.0:</p>
<ul>
<li>Multi-condition AND/OR groups (planned for v1.1)</li>
<li>URL / cookie / referrer / geolocation conditions</li>
<li>WooCommerce, ACF, or membership integrations</li>
<li>A settings dashboard</li>
</ul>
<p>If you need those today, <a href="https://wordpress.org/plugins/conditional-blocks/" rel="ugc">Conditional Blocks</a> and <a href="https://wordpress.org/plugins/block-visibility/" rel="ugc">Block Visibility</a> are excellent and well-established choices.</p>
<h4>For developers</h4>
<p>Register a custom condition in three steps. Implement the interface, add it to the registry, ship.</p>
<pre><code>add_action( 'renderwhen_register_conditions', function ( $registry ) {
    $registry->register( new My_Plugin\\Conditions\\Country_Condition() );
} );
</code></pre>
<p>Your condition class implements <code>RenderWhen\Conditions\Interface_Condition</code>:</p>
<pre><code>namespace My_Plugin\Conditions;

use RenderWhen\Conditions\Interface_Condition;

class Country_Condition implements Interface_Condition {
    public function get_id(): string {
        return 'country';
    }

    public function get_label(): string {
        return __( 'Visitor country', 'my-plugin' );
    }

    public function get_schema(): array {
        return array(
            'type'       => 'object',
            'properties' => array(
                'countries' => array(
                    'type'  => 'array',
                    'items' => array( 'type' => 'string' ),
                ),
            ),
        );
    }

    public function evaluate( array $settings, array $context ): bool {
        $current = my_plugin_detect_country();
        return in_array( $current, $settings['countries'] ?? array(), true );
    }
}
</code></pre>
<p>The full set of public filters:</p>
<ul>
<li><code>renderwhen_register_conditions</code> — register your conditions here</li>
<li><code>renderwhen_evaluate_{condition_id}</code> — last-mile override of any condition’s result</li>
<li><code>renderwhen_render_block_hidden</code> — fires when a block is hidden, useful for cache busters and SEO tools</li>
<li><code>renderwhen_device_type</code> — swap in your own device detection</li>
</ul>
<p>The plugin is developed openly on GitHub. Issues, PRs, and architecture discussions welcome: https://github.com/abhishekfdd/renderwhen</p>


RenderWhen for Blocks

Show or hide any block when conditions match. Developer-first API and true server-side rendering — hidden blocks never reach the browser.

<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>


Block Logic – Full Block Display Control

Works just like widget logic. Excellent plugin and easy to use.

Work With New WordPress Theme Editor

Block Logic adds a "Block Logic" field to the block editor, that lets you show or hide any block based on conditions.
