Reduce permalinks (category or post) that include entire hierarchy of categories to just having the lowest category in the hierarchy.
By default, WordPress replaces the %category% permalink tag in a custom permalink structure with the entire hierarchy of categories for the post’s first matching category. For example, assuming your site has a hierarchical category structure like so:
<pre><code>Applications
 |_ Desktop
 |_ Web
 |_ WordPress
</code></pre>
By default, if you have a permalink structure defined as <code>%category%/%year%/%monthnum%/%day%/%postname%</code>, your post titled “Best Plugins” assigned to the “WordPress” category would have a permalink of:
<pre><code>https://www.example.com/applications/web/wordpress/2008/01/15/best-plugins
</code></pre>
If you activate the Single Category Permalink plugin, this would be the permalink generated for the post (and recognized by the blog):
<pre><code>https://www.example.com/wordpress/2008/01/15/best-plugins
</code></pre>
In order for a category to be used as part of a post’s permalink structure, <code>%category%</code> must be explicitly defined in the Settings -> Permalinks admin page as part of a custom structure, i.e. <code>/%category%/%postname%</code>.
For category links, <code>%category%</code> is implied to follow the value set as the “Category base” (or the default category base if none is specified). So if your category base is ‘category’, the above example would list posts in the ‘WordPress’ category on this category listing page:
<pre><code>https://www.example.com/category/applications/web/wordpress/
</code></pre>
With this plugin activated, that link would become:
<pre><code>https://www.example.com/category/wordpress/
</code></pre>
NOTE: The fully hierarchical category and post permalinks will continue to work. The plugin issues a 302 redirect to browsers and search engines pointing them to the shorter URL.

<h3>Hooks</h3>
The plugin exposes one filter for hooking. Code using this filter should ideally be put into a mu-plugin or site-specific plugin (which is beyond the scope of this readme to explain). Less ideally, you could put them in your active theme’s functions.php file.
c2c_single_category_redirect_status (filter)
The ‘c2c_single_category_redirect_status’ hook allows you to specify an HTTP status code used for the redirect. By default this is 302.
Arguments:
<ul>
<li>$status (integer) : The default HTTP status code</li>
</ul>
Example:
<pre><code>/**
 * Change the redirection HTTP status to a 302.
 *
 * @param int $code The HTTP status code. By default 301.
 * @return int
 */
function scp_change_redirect_status( $code ) {
 return 302;
}
add_filter( 'c2c_single_category_redirect_status', 'scp_change_redirect_status' );
</code></pre>

Display a tree view structure in your front-end using shortcode using a range of different style templates.
Wolfe Candy Tree View is part of the Wolfe Candy suite of plugins that all work together to make <a href="https://wordpress.org/" title="Your favorite software" rel="ugc">WordPress</a> site creation that much easier.
Major features include:
<ul>
<li>The tree view displays any array of paths (e.g. ‘\a\b\c\d\’, ‘a\b\b’, ‘a\c’ etc) in Windows path format (not URL or Linux) as a hierarchy based on the specified style template (or default if nothing is specified). Note: path symbols may need to be switched if inputted manually e.g. \</li>
<li>There are a number of pure CSS style templates that are uploaded with the plugin. These can all be altered to suit your design. There are also a range of other templates available.</li>
<li>The hierachy list has a number of sources that can be specified from S3 structures, XML, file structures, upload folders, plugin folders, page hierarchy or a custom list.</li>
<li>Up to 7 levels of hierarchy can be displayed in any one tree.</li>
<li>End-nodes in the tree can hyperlink to files or other links so it can be used as a navigation tool.</li>
<li>Icons and HTML Special character are supported.</li>
<li>If media files are found as an end-node in a file tree, the image can be included in the tree as an image tile.</li>
<li>This can be combined with the Wolfe Candy Tool Suite for enriched functionality e.g. S3 bucket folder lists and using Private Content shortcode to limit the viewing of tree structures to specified roles.</li>
</ul>
