It’s in lib/util.php.
The list is rather limited on purpose, to try and use topic names that search engines and catalogs would use. There’s no standard (yet), so the closest I got was the wikipedia list from http://en.wikipedia.org/wiki/Category:Websites_by_topic.
Instead of editing the code and avoiding future updates, I’d much rather offer you way to modify the built-in list. Here are two options if you have the Pro version:
– Use the ngfb_og filter to change the topic in the Open Graph meta tags. Add the following to your (child) theme’s functions.php file:
add_filter( 'ngfb_og', 'my_filter_ngfb_og', 10, 1 );
function my_filter_ngfb_og( $og = array() ) {
if ( ! empty( $og['og:type'] ) && $og['og:type'] == 'article' )
$og['article:section'] = 'YourTopicName';
return $og;
}
– The other will be available in the upcoming version. Add your custom topic to the existing topics array. Same thing, add the following to your (child) theme’s functions.php file:
add_filter( 'ngfb_topics', 'my_filter_ngfb_topics', 10, 1 );
function my_filter_ngfb_topics( $topics = array() ) {
$topics[] = 'YourTopicName';
return $topics;
}
js.
Thank you!
The website in question is all about a small plumbing company. I find it absolutely bizarre that according to the Wiki list; the Super-level categories include items such as Fashion, Genealogy and Nostalgia, but positively nothing about things like “Home”, “Entrepreneur” or even something as simple as “Services”.
Hacking the plugin, as I read your response, wouldn’t be productive because the subject isn’t included in the super-list. Way too weird!
Thanks again – Be well!
Well, there’s nothing preventing you/us from customizing the list. I chose Wikipedia as the source, only because there wasn’t another readily available — and there’s no standard for the ‘article:section` meta tag (unfortunately).
You could use the ‘Commerce’ topic, or use the techniques outlined above to add your own.
