Additional Content
Description
Add additional content on a post per post basis in the edit or publish post screen. The additional content editor can be used with all public post types.
Use this plugin for content that you, for whatever reason, don’t want to be included in the post content itself, like shortcodes, or code snippets used by other plugins.
Another benefit of using this plugin is if you want content to be displayed before or after content that is automatically added by other plugins. The priority parameter will let you do just that.

What is PHP?
PHP is the scripting language used to build WordPress. It’s installed on your server by your host. The minimum required version for WordPress is PHP 5.2.4. This version has been unsupported since early 2011 and is potentially insecure. WordPress supports it to maintain backward compatibility for sites that are still using it.
This plugin is also build with PHP but it requires the PHP version of 5.4.0 or higher to work.
Follow these instructions to install the plugin.
- In your WordPress admin panel, go to Plugins > New Plugin, search for “additional content” and click “Install now”.

FAQ
- What is the priority option?
-
This plugin is basically a user interface for the_content filter. This filter allows themes and plugins to change (or add content to) post content before it’s displayed. The default priority for filters is 10. Higher numbers correspond with later execution of adding additional content. This option allows you to display the additional content before or after other plugins that add content with this filter.
