<p>This plugin enables the use of [if] shortcodes to work with conditional logic based on the existence of post meta or taxonomy terms on posts and pages.</p>
<p>Please consider taking a minute to rate the plugin or let me know any feature request. Thanks!</p>
<h4>Taxonomy</h4>
<p>With conditional logic for taxonomy terms, you can use names, slugs or term_ids:</p>
<ul>
<li>[if taxonomy=”category” slug=”cars”]Content to show[/if]</li>
<li>[if taxonomy=”category” name=”Cars”]Content to show[/if]</li>
<li>[if taxonomy=”category” id=”123″]Content to show[/if]</li>
</ul>
<h4>Post Meta</h4>
<p>Post meta (or custom field) logic can be used to check if a certain meta_key AND meta_value combination are present or just a meta_key:</p>
<ul>
<li>[if postmeta=”car_model”]Content to show if car model info is present[/if]</li>
<li>[if postmeta=”car_model” value=”Tesla Model S”]Content to show if car model is Tesla Model S[/if]</li>
</ul>


Logic Shortcodes

Use shortcodes for conditional logic based on post meta or taxonomy terms.

<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>
