categories – How to change the order of the subcategory and category in a post?

Question

You can write a get_the_terms filter to change the other the category values are returned, e.g.

function sort_the_terms( $terms,$post_id, $taxonomy ) { if ( 'categories' ===$taxonomy ) {
usort( $terms, function($term1, $term2 ) { // Better sort logic here return$term1->name <=> $term2->name; } ); } return$terms;
}
add_filter( 'get_the_terms', 'sort_the_terms', 20, 3 );

You’ll need to change the logic in the comparator to get the order you want, e.g. using information in wp_termmeta or the group or parent ID of the term. (If you’re using parents to build a hierarchy you might need something more complicated than just a usort though, since ‘place in hierarchy’ is going to be difficult to determine completely in a comparator.)
