hi tom,

when I enable meta > include terms, multiple categories are displayed (when a post has multiple categories)
would it be possible to limit the display only to the main category? if yes… please help 🙂

thank you for your great plugin

Hey Alex,

How is the main category determined? The first one to show up?

Let me know 🙂

hi tom,

thank you for your reply. as most of our posts belong to more than one category (or sub-category), I would like to only show one in order to keep the meta always only on one line and not on several lines as it happens now. which one is the main category is not really important as long as it is only one. the easiest to achieve, will be enough for us 🙂

thank you again
alex

Hey Alex,

Give this a shot:
```
add_filter( 'wpsp_terms_output', function() {
    $all_terms = get_the_terms( get_the_ID(), 'category' );
	
    $first_term = $all_terms[0];
	$url = get_term_link( $first_term->term_id );

    return sprintf( '<span class="wp-show-posts-terms wp-show-posts-meta"><a href="%1$s">%2$s</a></span>',
		$url,
        $first_term->name
    );
} );
```
Let me know 🙂

Hey Tom,

I tried adding this https://wpshowposts.com/support/topic/display-only-main-cateory-meta-terms/#post-7584 but it’s giving me a critical error on the site… I’m looking to display the last child essentially of the taxonomy term string.. not sure what I am doing wrong.

Thanks
