About this plugin
This plugin provides template tags that allow you to retrieve the name, path (relative or absolute), url, or fully marked-up link to a randomly chosen file or files in a specified directory.
Arguments to the functions permit you to limit what file(s) can be randomly selected based on a given set of file extensions. You can also explicitly specify files that should not be randomly selected.
This functionality can be useful for displaying random images/logos or including text from random files onto your site (writing excerpts, multi-line quotes, etc). Other ideas: random ads, random CSS files, random theme template selection.
Notes:
-
If you want to actually display the name of the random file, be sure to ‘echo’ the results:
-
Unless you limit the file search to only include a particular extension (via $extensions argument), all files in the specified $dir will be under consideration for random selection
-
Can be run inside or outside of “the loop”

Developer Documentation
md. That documentation covers the template tags and hooks provided by the plugin.
As an overview, these are the template tags provided by the plugin:
- c2c_random_file(): Retrieves the name of a random file from a specified directory and returns information based on the file.
- c2c_random_files(): Retrieves the name, path, or link to a specified number of randomly chosen files in a specified directory.
These are the hooks provided by the plugin:
- c2c_random_file: Filter to safely invoke c2c_random_file() in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site.
- c2c_random_files: Filter to safely invoke c2c_random_files() in such a way that if the plugin were deactivated or deleted, then your calls to the function won’t cause errors in your site.
