This plugin was created to show the categories for a single post in the sidebar.
The categories will be displayed in an unordered list.
You can choose the title for the widget in the sidebar if you wish.
If you’re using the plugin, please drop the link to your blog <a href="https://wordpress.org/support/topic/plugin-posts-categories-in-sidebar-using-this-widget" rel="ugc">here</a>.
Example:
<pre><code><li id="cz_post_cat-3" class="widget-container widget_cz_post_cat">
 <h3 class="widget-title">Topics</h3>
 <div class="cz-post-cats">
 <ul class="cz-cat-ul">
 <li class="cz-cat-li"><a href="http://xxx.xxx.xxx/topic/facebook/">Facebook</a></li>
 <li class="cz-cat-li"><a href="http://xxx.xxx.xxx/topic/jobs/">Jobs</a></li>
 </ul>
 </div>
</li>
</code></pre>
It uses the <code>is_single()</code> query in php so that it ONLY shows up on single posts. Not pages.
<h3>Arbitrary section</h3>
Anyone need any info here?

Displays the categories for a single post in the sidebar.

You know when you search for something on a site and it finds just one result? You then have to click into it to display it. That’s annoying. It’s also adding an extra page load which is not necessary.
And what about if you search for an exact match for a title and, well, it serves it up along with a number of other possible results. Hey, why didn’t you just show me the one that I typed the name of in exactly? Well, you can do that too. Cool, eh?
This plugin simply removes this middle step – if your search returns one result or you type in the name of a title, it will be shown in all its post/page (delete as appropriate) glory. As well as a quicker answer for your visitor, removing this improves your site’s sustainability (okay, just a little… but every little helps, right?).
The code also passes WordPress and WordPress VIP coding standards. Because you’re worth it.
