How to customize the_archive_title()?

by

In my child theme’s archive.php, I have the following code for displaying the title of my archive pages:

<?php
    the_archive_title( '<h1 class="page-title">', '</h1>' );
?>

But that displays my titles as “Category: Category Title” instead of simply the title without the prepended “Category: “.

My first instinct was to override get_the_archive_title() from wp-includes/general-template. But from what I’ve read, apparently I’m not supposed to ever alter wordpress core stuff, even with overrides from a child theme.

So what is the best-practice way to control the output of the_archive_title()?

If you look at the source code of get_the_archive_title(), you will see that there is a filter supplied, called get_the_archive_title, through which you can filter the output from the function.

You can use the following to change the output on a category page

add_filter( 'get_the_archive_title', function ( $title ) {

    if( is_category() ) {

        $title = single_cat_title( '', false );

    }

    return $title;

});
