Suppress creator and add feature image to RSS feed

Hi there,

This isn't something the theme controls, but there are plugins out there:
https://wordpress.org/plugins/rss-featured-image/

I wonder if the theme controls the author display.. We could try this:

add_filter( 'generate_post_author_output', function( $output ) {
    if ( is_feed() ) {
        return '';
    }

    return $output;
} );

Not sure if that will work or not, but it's worth a shot.

Found this: https://wordpress.stackexchange.com/questions/47726/remove-or-edit-dccreator-in-feeds

I ended up going with the code below in our functions.php file to set the author to a static value. Seems to be working. I'll look in to the plugin for adding the feature images.

Thanks Tom!

//Set author for RSS feeds
function set_the_author( $display_name ) {
    if ( is_feed() ) {
        return 'My Static Author Name';
    }
}
add_filter( 'the_author', 'set_the_author', PHP_INT_MAX, 1 );

Awesome, glad you found a solution! :)

Revisiting this need. We thought using "the_author" function was working. It does, however the Author field in the Media Library, Posts view, etc. gets blanked out (no value is shown) when the following is added to our child theme functions.php:

//Set author for RSS feeds
function mod_author( $display_name ) {

    if ( is_feed() ) {
        return 'New Author';
    }
}

add_filter( 'the_author', 'mod_author', PHP_INT_MAX, 1 );

We tried Tom's suggestion and it doesn't appear to affect a change to the RSS feeds:

add_filter( 'generate_post_author_output', function( $output ) {
    if ( is_feed() ) {
        return 'New Author';
    }

    return $output;
} );

Thanks for any tips you can pass along.

Also tried the following, but get an error when trying to view the RSS feed:

OK - I think the following seems to be working. It allows you to customize a copy of the feed-rss2.php template and doesn't blank out the Author column in the Media Library, Pages list, etc.

1) Copy the feed-rss2.php from the wp-includes directory to your child theme directory.
2) Modify the feed-rss2.php as desired.
3) Add the following to your child theme's functions.php file

//Load custom RSS feeds template
remove_all_actions( 'do_feed_rss2' );
add_action( 'do_feed_rss2', function( $for_comments ) {
	if ( $for_comments )
		load_template( ABSPATH . WPINC . '/feed-rss2-comments.php' );
	else
	{
		if ( $rss_template = locate_template( 'feed-rss2.php' ) )
			// locate_template() returns path to file
			// if either the child theme or the parent theme have overridden the template
			load_template( $rss_template );
		else
			load_template( ABSPATH . WPINC . '/feed-rss2.php' );
	}
}, 10, 1 );   

Glad you found a solution - thanks for sharing it. This isn't something I've worked with a bunch, but it's good to know you're able to overwrite the template like that.
