Taxonomy slug by term ID

Question

I'm trying to modify wp_nav_menu to display term thumbnails. To get those thumbnails I need term ID and taxonomy slug: $thumbnailimg = get_the_term_thumbnail($term_id, '$taxonomy', 'medium');

I managed to get term ID for it with: $term_id = (int)$item->object_id;

But now I need to check if that object is a term AND what custom taxonomy that term belongs to (I have 2 of them).

Can anyone help me to solve this problem? :)

Answer 1

For a menu object $item:

• $item->object stores the object the menu item refers to, e.g. 'post', 'page', 'my-cpt', or 'my-taxonomy' (the post type name, or the taxonomy name)
• $item->type stores what 'type' of object is it, either: 'post_type' or 'taxonomy'.

For custom links, these are both custom

See if these functions will work for what you are trying to do:

• term_exists
• get_taxonomies
