Image Feed Widget works well with extra function.php code

Problem: I needed to syndicate my one blog’s (site 1)categories as two separate feeds. I needed to include images in the feeds as well. These feeds needed to be “imported” into my other blog’s (site 2) sidebar.

Solution: in site 1’s function.php file I added the following code found on this website: https://www.wpbeginner.com/wp-tutorials/wordpress-custom-fields-101-tips-tricks-and-hacks/ :

function wpbeginner_postrss($content) {
global $wp_query;
$postid = $wp_query->post->ID;
$coolcustom = get_post_meta($postid, ‘coolcustom’, true);
if(is_feed()) {
if($coolcustom !== ”) {
$content = $content.”

<div>”.$coolcustom.”</div>\n”;
}
else {
$content = $content;
}
}
return $content;
}
add_filter(‘the_excerpt_rss’, ‘wpbeginner_postrss’);
add_filter(‘the_content’, ‘wpbeginner_postrss’);

I modified for my own custom field.

On site 2 I used the image feed widget to import the two feeds. But I had to be sure to use the following feed url(s): https://www.example.com/category/categoryname/feed/rss

i initially didn’t use the …/feed/rss and the feed wouldn’t import the custom field image I had set up. by including the trailing …/rss at the end of the feed url it worked perfectly.
