I needed a quick way to automatically include external page content in my WordPress Rising Stars post.
There are two tables with latest plugin standings that are automatically generated and I wanted the post to be updated automatically when they update too.
Easiest way to accomplish this is through WordPress shortcode API with a simple code that you can add into the theme functions.php file:
Here is the code:
function show_file_func( $atts ) { extract( shortcode_atts( array( 'file' => '' ), $atts ) ); if ($file!='') return @file_get_contents($file); } add_shortcode( 'show_file', 'show_file_func' ); |
This allows you to write something like this anywhere in your post:
[show_file file="http://www.prelovac.com/rise.html"] |
The snippet above will automatically include the contents of given page into your post. Handy, isn't it?

This is a very dangerous shortcode that could allow authors to read any file on the server filesystem. You can make it safer by using WP’s HTTP api instead of file_get_contents(), but it’ll still be dangerous.
[ show_file file="/etc/passwd" ] !
interesting code, thanks for always staying on top of things :)
is there anyway to use this code to embed the remote file into a wordpress widget or the sidebar, instead of a post? Or maybe a wordpress plugin that keeps the last post on the homepage sticky, instead of the first like other plugins ive seen. thanks.
