        if ( ! empty( $slug ) ) {

            return str_replace( '%kategorie_dladomu%' , $slug , $post_link );

        }

    }

    return $post_link;

My Answer:
It looks like there might be a small issue in your code. In the line where you are checking for the parent term, you are using `$terms->parent` instead of `$term->parent` and `$terms->term_id` instead of `$term->term_id`.

Here is the corrected code:

php
add_filter('post_type_link', 'projectcategory_permalink_structure', 10, 4);
function projectcategory_permalink_structure($post_link, $post, $leavename, $sample) {
if (false !== strpos($post_link, '%kategorie_dladomu%')) {
$terms = get_the_terms($post->ID, 'kategorie_dladomu');

foreach ( $terms as $term ) {
if ( $term->parent == 0 ){
$category = $term->slug;
foreach( $terms as $subterms ){
if ( $subterms->parent == $term->term_id ){
$subcategory = $subterms->slug;
}
}
}
}
$slug = "$category/$subcategory";
if ( ! empty( $slug ) ) {
return str_replace( '%kategorie_dladomu%' , $slug , $post_link );
}
}
return $post_link;
}


Please try this corrected code and see if it resolves the issue with the URLs not working. Let me know if you need any further assistance.
