Description

A safe and reliable WordPress shortcode for PHP's file_get_contents() function.

Shortcode Attributes

body = Keep only the content between <body></body> HTML tags (default is true).
cache = Number of seconds to cache the contents (defaults is 3600 seconds).
class = Wrap the content in the specified div class (default is none).
esc_html = Escape HTML characters (default is false).
file = Path to a local file (relative to the wp-content/ folder).
filter = Apply the specified filter to the content (default is none).
more = Add more link on non-singular web pages (default is true).
pre = Wrap the content in <pre></pre> HTML tags (default is false).
url = URL or file URI.
utf8 = Encode HTML entities (default is true).

Note that all local file paths are relative to the wp-content/ folder - you cannot include files outside the wp-content/ folder. For example, the shortcode attributes url="file://dir/file.html" and file="/dir/file.html" are both read as wordpress/wp-contents/dir/file.html. The .. folder name is stripped from file paths to prevent backing out of the wp-content/ folder.

Shortcode Name

The WPFGC_SHORTCODE_NAME constant can be defined in your wp-config.php file to add an additional custom shortcode name (the default shortcode names are 'wp-file-get-contents' and 'wpfgc').

define( 'WPFGC_SHORTCODE_NAME', 'include' );

Shortcode Examples

[wpfgc url="http://example.com/dir/file.html"]
[wpfgc url="http://example.com/counter/" cache="7200"]
[wpfgc url="file://dir/file.html"]
[wpfgc file="/dir/file.txt" pre="true" filter="my_custom_filter_name" cache="600"]
