Adding $$custom_field to kses_allowed_protocols.

I had noticed a problem with using the $$custom_field:xx$$ parameter in posts, which because shortcoder uses this parameter to include custom fields and because shortcoder is now a post_type has now been causing problems for us in shortcodes.

I originally wanted to post for support here but since the problem seemed not specific to shortcoder at first I posted it on the general support forum. I have resolved it there and noticed that it is somewhat specific to shortcoder after all because the use of the $$custom_field:xx$$ syntax is specific to shortcoder.

I propose something similar to the following code be added to the shortcoder plug-in to make sure that shortcoder’s custom field syntax is allowed in anchor tags.

add_filter( 'kses_allowed_protocols', 'dzb_allow_custom_field_protocol' );
function dzb_allow_custom_field_protocol( $protocols ) {
	$protocols[] = '$$custom_field';
	return $protocols;
}
