Display subtitle in feed?

I figured it out myself. Just in case anyone else ever needs a similar functionality, edit includes/feed-rss2.php, and add

<?php if( function_exists( ‘the_subtitle’ ) ) the_subtitle( ”, ‘: ‘ ); ?>

Where you want athe subtitle. Note, this also inserts a colon and a space after the subtitle.

Thanks again for the plugin!

No, please don’t hack core files. That’s a terrible idea and your edits will either be overwritten when you update WordPress or you’ll be locked into your current version and will never update.

The RSS feed title looks to be filterable. I can’t test this write now, but this might be close to what you need.

function kia_rss_subtitle( $title, $sep ){
	if( function_exists( 'the_subtitle' ) ) {
		$title = the_subtitle( '', ': ', false ) . $title;
	}

	return $title;
}
add_filter( 'wp_title_rss', 'kia_rss_subtitle' );

Thank you! I should have mentioned I was using a plugin that let me have copies of the feed*.php files in my theme directory for modifying, but this lets me use one less plugin.

I made one modification, the way you have it was appending the most recent subtitle to the title of the feed. Just need to change ‘wp_title_rss’ to ‘the_title_rss’. This will place it before the item title, instead of after the feed title.

Thanks again!

Good catch. I don’t know much about feeds, but it seemed like there should’ve been a filter there and there was!

Where do you put this code ?

function kia_rss_subtitle( $title, $sep ){
if( function_exists( ‘the_subtitle’ ) ) {
$title = the_subtitle( ”, ‘: ‘, false ) . $title;
}

return $title;
}
add_filter( ‘wp_title_rss’, ‘kia_rss_subtitle’ );

I used to say your theme’s functions.php, but this isn’t really theme-related. Therefore you should make it a site-specific snippet plugin.

Thanks

but I get this error when viewing the feed page : This page contains the following errors:

No error when removing the code from the file

Any suggestions what it might be ?

Thanks in advance

It means you are missing the second argument, $sep. I’d probably just remove that argument. As I mentioned above, the code is untested.

thanks anyways ??
