I’ve modified a function I found to do what I need, although it works, unfortunately the results returned are not in any specific order, I need them to be alphabetical.
This script returns a list of subcategories from Woocommerce:
function get_product_subcategories_list( $category_slug ){
$terms_html = array();
$taxonomy = 'product_cat';
// Get the product category (parent) WP_Term object
$parent = get_term_by( 'slug', $category_slug, $taxonomy );
// Get an array of the subcategories IDs (children IDs)
$children_ids = get_term_children( $parent->term_id, $taxonomy );
// Loop through each children IDs
foreach($children_ids as $children_id) {
$term = get_term( $children_id, $taxonomy ); // WP_Term object
$term_link = get_term_link( $term, $taxonomy ); // The term link
$thumbnail_id = get_woocommerce_term_meta( $term->term_id, 'thumbnail_id', true );
if ( is_wp_error( $term_link ) ) $term_link = '';
// Set in an array the html formatted subcategory name/link
$terms_html[] = '<li><a href="' . esc_url( $term_link ) . '">' . $term->name . '</li></a>';
}
return '<ul>' . implode( $terms_html ) . '</ul>';
}
…and not that it matters, but this is in my template:
get_product_subcategories_list( $post->post_name );
The problem is that $terms_html[]
is returning this…
<li><a href="https://example.com/pants">Pants</a></li>
<li><a href="https://example.com/shoes">Shoes</a></li>
<li><a href="https://example.com/hats">Hats</a></li>
…but I need it to be alphabetical like this:
<li><a href="https://example.com/hats">Hats</a></li>
<li><a href="https://example.com/pants">Pants</a></li>
<li><a href="https://example.com/shoes">Shoes</a></li>

Since
get_term_children
doesn’t provide any way of sorting. Just treat the array with the sorting yourself.Push the
->name
in the array as key pairs. Then just utilizeksort()
. Like so:Try
sort
