How to display the parent category in the archive?

  • I wanted to display the parent category name before the actual category in my archives page. It currently is:

    <h1>Categoria: <b>"<?php echo single_cat_title(); ?>"</b></h1>

    I googled and landed on this topic, suggesting that I replace <?php echo single_cat_title(); ?> for <?php if( $category->parent ) { echo get_the_category_by_ID($category->parent) . ' - '; } single_cat_title(); ?>, but it didn’t work. It still shows only the child category name.

    I also tried <?php echo get_the_category_by_ID($category->parent); ?> - <?php single_cat_title(); ?>, but got an error saying “CATCHABLE FATAL ERROR: OBJECT OF CLASS WP_ERROR COULD NOT BE CONVERTED TO STRING IN /HOME/…/ARCHIVE.PHP ON LINE 8”

    How can I get something like:
    <h1>Categoria: <b>"<parent category> - <?php echo single_cat_title(); ?>"</b></h1>

    Thanks.

    Hello,

    You can use the get_category_parents function to do that:

    <?php echo get_category_parents($cat, TRUE, ' &raquo; '); ?>

    Thank you. It works perfectly.
    Just one more question: is there any way to not get a ? after the last category is displayed? So it’d be “Parent Category ? Child Category” instead of “Parent Category ? Child Category ? “?
    Thanks.

    Ok. Another thing.
    I’d like to have the categories displayed before the title of a post when in a single page.
    Like “Parent Category ? Child Category ? Post Title”. When I tried just using the get_category_parents function like:

    <span class="title">
	<?php echo get_category_parents($cat, TRUE, ' ? '); ?> <a
href="<?php echo get_permalink() ?>" rel="bookmark" <?php the_title();
?>><?php the_title(); ?></a>
</span>

    it didn’t work and I got the error “catchable fatal error: object of class wp_error could not be converted to string in /home/…/single.php on line 7”.

    Is there anyway to do that?
