The RPS Include Content plugin is useful when you need to include the same content across many posts or pages. For example, you may want to place your company boilerplate at the bottom of press releases in your News section. Instead of pasting the boilerplate copy at the end of each of these pages, you can now insert the shortcode (along with the post ID, and for multisite configurations, the blog ID) where that content should appear.
When you modify your source copy, changes will appear on all pages that contain the shortcode. There’s no need to open and modify multiple pages.
When a user previews the post from the WordPress Administration, the included content is distinguished with an on-hover highlight. A link is provided so that the source content can be conveniently accessed and modified. The preview of the include will not distort the target page – the width, height and position will remain as defined by the site.
To easily obtain the blog ID and post ID, install the free <a href="https://wordpress.org/extend/plugins/rps-blog-info/" rel="ugc">RPS Blog Info</a> plugin, which places that information (and much more) on your WordPress 3.3 Toolbar.
