<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.
