The plugin provides a widget called “Linkify Tags” as well as a template tag, <code>c2c_linkify_tags()</code>, which allow you to easily specify tags to list and how to list them. Tags are specified by either ID or slug. See other parts of the documentation for example usage and capabilities.

<h3>Developer Documentation</h3>
Developer documentation can be found in <a href="https://github.com/coffee2code/linkify-tags/blob/master/DEVELOPER-DOCS.md" rel="nofollow ugc">DEVELOPER-DOCS.md</a>. That documentation covers the template tag and hook provided by the plugin.
As an overview, this is the template tag provided by the plugin:
<ul>
<li><code>c2c_linkify_tags()</code> : Template tag to display links to each of any number of tags specified via tag IDs/slugs. You can customize text to show before and/or after the entire listing, between each tag, and what to display (if anything) when no tags are listed.</li>
</ul>
This is the hook provided by the plugin:
<ul>
<li><code>c2c_linkify_tags</code> : Allows use of an alternative approach to safely invoke <code>c2c_linkify_categories()</code> in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site.</li>
</ul>

Linkify Tags

Turn a string, list, or array of tag IDs and/or slugs into a list of links to those tag archives. Provides a widget and template tag.
