Some people want to be able to extend the list of mime-types supported by the WordPress inline-uploader. There are a number of different ways in which this could be achieved ranging from adding a option to allow any file type through to a plugin which allows easy configuration of an extra list of mime-types through the administration interface.
Seeing as a hook exists (upload_mimes) to filter the list of supported mime-types it is fairly easy to knock together a simple plugin which adds a set of mime-types.
< ?php
/*
Plugin Name: mime-type adder
Description: Adds extra mime-types
Author: Peter Westwood
Version: 0.01
Author URI: http://blog.ftwr.co.uk/
*/
add_filter('upload_mimes','pjw_upload_mimes');
function pjw_upload_mimes($mimes)
{
$mime_types = array ('ac3' => 'audio/ac3', 'mpa' => 'audio/MPA', 'flv' => 'video/x-flv');
return array_merge($mimes,$mime_types);
}
?>
However simple that plugin may be it doesn’t give you a nice admin interface and an easy way to manage the list in future which is where my new plugin WordPress mime config steps in. The plugin adds a new options page as Options … Mime-types which allows you to add/delete the extra mime-types.
By default the following extra mime-types are registered: audio/ac3, audio/MPA and video/x-flv.
The latest version of the plugin may be downloaded here: pjw-mime-config.0.50.zip
