[wp-hackers] Custom feeds: Full and summary

[Mark Jaquith]

I was bored... this works:

<?php
/*
Plugin Name: Feed Type Override
Description: Allows you to pass ?feedtype=full or ?feedtype=excerpt  
to feed URIs to force full or excerpted feeds.  Without a feedtype  
designated, it uses your default setting.
Author: Mark Jaquith
Author URI: http://txfx.net/
*/

function txfx_feedtype_override($option) {
	if ( $_GET['feedtype'] == 'full' )
		return false;
	if ( $_GET['feedtype'] == 'excerpt' )
		return true;
	return $option;
}
add_filter('option_rss_use_excerpt', 'txfx_feedtype_override');
?>
