Change the name Category - Not change category name

Question

My client has a Law Firm, and he is asking if we can change the term CATEGORIES to JURISDICTION. (I tried to explain that he could create a new category called "jurisdiction", but that is not an option)

Answer 1

Use taxonomy_labels_category filter (documented here: https://developer.wordpress.org/reference/hooks/taxonomy_labels_taxonomy/) in order to change any of the labels that you need changed.

Here's what works for me:

add_filter( 'taxonomy_labels_category', 'filter_category_labels' );
function filter_category_labels( $labels ) {
    $labels->menu_name = 'Jurisdiction';
    return $labels;
}

You will have to change quite a few other values in the $labels object though.

Here's a full list of the properties of the object:

• name
• singular_name
• search_items
• popular_items
• all_items
• parent_item
• parent_item_colon
• edit_item
• view_item
• update_item
• add_new_item
• new_item_name
• separate_items_with_commas
• add_or_remove_items
• choose_from_most_used
• not_found
• no_terms
• items_list_navigation
• items_lists
• most_used
• back_to_items
• menu_name
• name_admin_bar
