显示类别父母和他们的孩子

Question

I would like to display all the categories related to a post, along with their parents.

Currently I have something like this: Dog, Female, London, Newborn

I'm using this code:

$categories_list = get_the_category_list( __( '</br> ', 'twentytwentyone' ) );
            if ( $categories_list ) {
                printf(
                    '<p class="cat-links"> ' . ( $categories_list ) . ' </p></div>'
                );
            }

But I would like to also display the parent category as such:

<----------->

Type: Dog

Gender: Female

Location: London

Age: Newborn

<----------->

Note: I have tried simply writing HTML to group these as such

Type

Gender

Location

Age

This doesn't work because the categories listed are not ordered, therefore sometimes the output will be something like (Gender: Dog, Location: Female,Type: London)

Thank you in advance!

Answer 1

try this:

foreach(get_categories() as $category){
    echo ($category->parent?get_category($category->parent)->name.': ':'').$category->name.'</br>';
}

Answer 2

foreach(get_the_category() as $category){
                echo ($category->parent?get_category($category->parent)->name.': ':'').$category->name.'</br>';
            }

This worked!
