Instructions: Add the following code to the functions.php file of your WordPress theme to include external file shortcode.

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' );

Now you can use this shortcode given below with your external file link to include the external file in your WordPress posts and pages.

[show_file file="http://www.mysite.com/somefile.html"]
