By default in WordPress, if the plugin that provides the functionality to handle any given shortcode is disabled, or if a shortcode is improperly defined in the content (such as with a typo), then the shortcode in question will appear on the site in its entirety, unprocessed by WordPress. At best this reveals unsightly code-like text to visitors and at worst can potentially expose information not intended to be seen by visitors.
This plugin prevents unhandled shortcodes from appearing in the content of a post or page. If the shortcode is of the self-closing variety, then the shortcode tag and its attributes are not displayed and nothing is shown in their place. If the shortcode is of the enclosing variety (an opening and closing tag bookend some text or markup), then the text that is being enclosed will be shown, but the shortcode tag and attributes that surround the text will not be displayed.
See the Filters section for more customization tips.

<h3>Developer Documentation</h3>
Developer documentation can be found in <a href="https://github.com/coffee2code/hide-broken-shortcodes/blob/master/DEVELOPER-DOCS.md" rel="nofollow ugc">DEVELOPER-DOCS.md</a>. That documentation covers the hooks provided by the plugin.
As an overview, these are the hooks provided by the plugin:
<ul>
<li><code>hide_broken_shortcode</code> : Customizes what, if anything, gets displayed when a broken shortcode is encountered.</li>
<li><code>hide_broken_shortcodes_filters</code> : Customizes what filters to hook to find text with potential broken shortcodes.</li>
</ul>

Hide Broken Shortcodes

This plugin does what it says. Really a great plugin. Thank you developer.

Works Great!

Prevent broken shortcodes from appearing in posts and pages.

This plugin provides a template tag which acts as a modified version of WordPress’s built-in template tag, <code>the_category()</code>. <code>the_category()</code> lists all categories directly assigned to the specified post. <code>c2c_parentless_categories()</code> lists those categories, except for categories that are parents to other assigned categories.
For example, assume your category structure is hierarchical and looks like this:
<pre><code>Vegetables
|-- Leafy
| |-- Broccoli
| |-- Bok Choy
| |-- Celery
|-- Fruiting
| |-- Bell Pepper
| |-- Cucumber
| |-- Pumpkin
|-- Podded
| |-- Chickpea
| |-- Lentil
| |-- Soybean
</code></pre>
If you directly assigned the categories “Fruiting”, “Cucumber”, and “Pumpkin” to a post, <code>c2c_parentless_categories()</code> would return a list that consists of: “Cucumber”, and “Pumpkin”. Notice that since “Fruiting” was a parent to a directly assigned category, it is not included in the list.
By default, categories are listed as an HTML list. The first argument to the template tag allows you to define a custom separator, e.g. to have a simple comma-separated list of categories: <code><?php c2c_parentless_categories( ',' ); ?></code>.
As with categories listed via <code>the_category()</code>, categories that are listed are presented as links to the respective category’s archive page.
Example usage (based on preceding example):
<ul>
<li><code><?php c2c_parentless_categories(); ?></code></li>
</ul>
Outputs something like:
<pre><code><ul><li><a href="http://yourblog.com/category/fruiting/cucumber">Cucumber</a></li>
<li><a href="http://yourblog.com/category/fruiting/pumpkin">Pumpkin</a></li></ul>
</code></pre>
<ul>
<li><code><?php c2c_parentless_categories( ',' ); ?></ul></code></li>
</ul>
Outputs something like:
<pre><code><a href="http://yourblog.com/category/fruiting/cucumber">Cucumber</a>, <a href="http://yourblog.com/category/fruiting/pumpkin">Pumpkin</a>
</code></pre>

<h3>Developer Documentation</h3>
Developer documentation can be found in <a href="https://github.com/coffee2code/parentless-categories/blob/master/DEVELOPER-DOCS.md" rel="nofollow ugc">DEVELOPER-DOCS.md</a>. That documentation covers the template tags and hooks provided by the plugin.
As an overview, these are the template tags provided by the plugin:
<ul>
<li><code>c2c_parentless_categories()</code> : Outputs the parentless categories.</li>
<li><code>c2c_get_parentless_categories_list()</code> : Returns the list of parentless categories.</li>
<li><code>c2c_get_parentless_categories()</code> : Returns the list of parentless categories for the specified post.</li>
</ul>
These are the hooks provided by the plugin:
<ul>
<li><code>c2c_parentless_categories</code> (action), <code>c2c_get_parentless_categories_list</code>, <code>c2c_get_parentless_categories</code> (filters) : 
Allows for an alternative approach to safely invoke each of the identically named functions in such a way that if the plugin were deactivated or deleted, then your calls to the functions won’t cause errors on your site.</li>
<li><code>c2c_parentless_categories_list</code> (filter) : 
Customizes the return value of the <code>c2c_parentless_categories_list()</code> function.</li>
<li><code>c2c_get_parentless_categories_omit_ancestors</code> (filter) : 
Customizes the function argument indicating if ancestor categories of all directly assigned categories (even if directly assigned themselves) should be omitted from the return list of categories.</li>
</ul>

Parentless Categories

Provides a template tag like the_category() to list categories assigned to a post except those that have a child category also assigned to the post.
