[Resolved] Posts excerpts

[David]

Ok, so this PHP Snippet:

function db_show_excerpt_child_term( $show_excerpt ) {

    $parent_term = get_term_by('slug', 'anecdotes-list', 'category');
    if (is_category() && $parent_term && get_queried_object()->parent == $parent_term->term_id) {
        return true;
    }	
	return $show_excerpt;
}
add_filter( 'generate_show_excerpt','db_show_excerpt_child_term' );

It will:

1, get our $parent_term that has the slug of anecdotes-list
2. check if the current archive term is a child of the parent.
3. is yes it will tell GP to shown the excerpt.

Thanks, Dave.

I just added it as a Snippet.
However, I see no change.

Could it be because I’m running a child theme?

[David]

Ok, it is working but my understanding of whats required obviously is obviously not lol

See here:

https://understand-culture.com/category/anecdotes-list/agreements-anecdotes/

The agreements-anecdotes is an archive page that is a child term of the anecdotes-list
And its showing an excerpt now. which is what that code does.

So lets start over 🙂
Can you show me the page where you want to see a list of all Anecdotes that show just the excerpt.

[John]

Gladly, Dave.

Please go to:
https://understand-culture.com/anecdotes/

Click on my last name – Magee – under authors.
Or simply pick any of the topics.

I have the respective anecdotes groups by
topic (category), and by author. Currently,
I’m the only author.

[David]

OK…. so this is where things get tricky.

If i choose the topic of Agreements then it opens the child term archive i shared above ie.

https://understand-culture.com/category/anecdotes-list/agreements-anecdotes/

And that shows the excerpt. Is that correct?

Then we can discuss the tricky part…..

[John]

On my side I see that the post “Strange Black Man”
has been successfully excerpted.

But if you access anecdote-posts from other entry
points – i.e. Magee or via a topic – I see that some
anecdote-posts are excerpted, while others are not.

[David]

OK, after some head scratching, this may do what you require.

What it should do on any category archive, if a post has a category term that includes the string: anecdotes it will set that post to display the excerpt.

function db_show_excerpt_child_term( $show_excerpt ) {
    $terms = get_the_terms( $post->ID, 'category' );
    if ( is_category() && $terms && ! is_wp_error( $terms ) ) {
        foreach ( $terms as $term ) {
            if ( strpos( $term->slug, 'anecdotes' ) !== false ) {
                return true;
            }
        }
    }
    return $show_excerpt;
}
add_filter( 'generate_show_excerpt','db_show_excerpt_child_term' );

Hi Dave,

It works great if and when you choose a topic.

However, if you choose “Magee” or “Germany” or
“USA” then no excerpts. Crazy.

Is that the case when you test?

John

[John]

We got this solved, Dave.

Go to:
https://understand-culture.com/anecdotes/

Pick any topic or Germany or USA.
All anecdotes are excerpted.

Great work !

John

[David]

Glad to hear that!

[John]

Thanks, Dave.
