Shortcodes can be added to Post Excerpts, Page Titles, Post Titles, Widgets, Widget Titles, Custom Fields, Site Title and Description, not just Pages and Posts as is already provided by WordPress itself. This allows Shortcodes to be used in Sidebars, Menus, Headers, Footers and even the HTML <code><title></code> element that appears in the Title Bar of most browsers.
A Settings page includes checkboxes to select where Shortcodes might appear:
<ul>
<li>In Post Excerpts, both manual and automatically-created Excerpts</li>
<li>In Page and Post Titles</li>
<li>In Browser Title Bar via <code><title></code></li>
<li>In Widgets used in Sidebars, Menus, Headers, Footers, etc.</li>
<li>In Widget Titles</li>
<li>In Site Title, Description and other bloginfo options</li>
<li>In Page or Post Custom Fields</li>
</ul>
Priority is an Advanced Setting beside each checkbox that controls the timing of the WordPress Filter associated with each Where? setting. This is provided solely to address conflicts with other themes and plugins that use the same WordPress Filter (“hook”).
A default Warning feature, which can be disabled on the Settings page, displays a message at the top of every Admin panel if the plugin is Activated but doing nothing because no Where? checkboxes are selected (other than the mandatory In Pages and In Posts settings).
All Shortcodes are supported by this plugin, no matter whether you are using Shortcodes defined by:
<ul>
<li>WordPress itself, such as <code>[gallery]</code>, <code>[audio]</code>, <code>[caption]</code>, <code>[embed]</code> or <code>[video]</code></li>
<li>Jetpack Shortcode Embeds</li>
<li>Your Active Theme</li>
<li>Another Plugin, for example, 
Current Year and Copyright Shortcodes</li>
<li>Writing your own Plugin and using the <code>add_shortcode()</code> function</li>
<li>Using a Shortcode creation Plugin, for example, Shortcode Exec PHP</li>
</ul>
Future versions will include more areas of the WordPress web site where Shortcodes may be used, based on the needs of users of this Plugin.
No attempt has been made to allow Shortcodes to be used to display values in Admin panels. This is the default WordPress behaviour, and changing it may have unintended (negative) consequences.
Plugin Developers may find the Table-Driven Design of interest. This was a popular concept in the 1980s and was used in this plugin to simplify the use of WordPress Filters. The two-dimensional global array $jr_saoe_filters is the Table involved.
This plugin was created to satisfy a request from a user of the <a href="https://wordpress.org/plugins/jonradio-current-year-and-copyright-shortcodes/" title="jonradio Current Year and Copyright Shortcodes" rel="ugc">Current Year and Copyright Shortcodes plugin</a> to use these Shortcodes in a Page Title.

Shortcodes Anywhere or Everywhere

Allows Shortcodes to be used nearly everywhere, not just in posts and pages.

The <a href="http://www.vanderwijk.com/wordpress/wordpress-custom-post-widget/?utm_source=wordpress&utm_medium=website&utm_campaign=custom_post_widget" rel="nofollow ugc">Content Blocks</a> allows you to display the contents of a specific custom post in a widget on in the content area using a shortcode.
Even though you could use the text widget that comes with the default WordPress install, this plugin has some major benefits:
<ul>
<li>The Content Blocks plugin enables users to use the WYSIWYG editor for editing the content and adding images.</li>
<li>If you are using the standard WordPress text widgets to display content on various areas of your template, this content can only be edited by users with administrator access. If you would like non-administrator accounts to modify the widget content, you can use this plugin to provide them access to the custom posts that provide the content for the widget areas.</li>
<li>You can even use the featured image functionality to display them in a widget.</li>
<li>The Content Blocks plugin is compatible with the WPML Multi-Language plugin and automatically shows the correct language in the widget area.</li>
<li>The Content Blocks can be included in posts and pages using the built-in shortcode functionality.</li>
</ul>
This plugin creates a ‘content_block’ custom post type. You can choose to either display the title on the page or use it to describe the contents and widget position of the content block. Note that these content blocks can only be displayed in the context of the page. I have added ‘public’ => false to the custom post type which means that it is not accessible outside the page context.
To add content to a widget, drag it to the required position in the sidebar and select the title of the custom post in the widget configuration.

Content Blocks (Custom Post Widget)

I was looking for something like this that goes perfectly with page builder based on widgets. Easy to use, simple and gets the job done.

Simple and effective

This plugin enables you to edit and display Content Blocks in a sidebar widget or using a shortcode.
