id summary reporter owner description type status priority milestone component version severity resolution keywords cc focuses 13889 permalinks for 'hierarchical' custom taxonomies do not behave hierarchically - is this correct? yeswework dd32 "with conventional Categories, the permalinks generated and recognised by WordPress reflect the true hierarchy – so you might have a parent category books, a subcategory fiction, a further subcategory novels, and so on, and a function like wp_list_categories would then generate the appropriate link /books/fiction/novels/ etc... with custom taxonomies that have 'hierarchical = true', the behaviour is generally identical to Categories (eg. in the GUI). and yet the permalinks generated / accepted do not reflect the hierarchical structure – instead only one level appears to be accepted: either /books/fiction or /books/novels but not /books/fiction/novels etc... I can't tell whether this is a bug or a feature, or understand why it would be different - nor could I find any reference to it after an extensive search. can anyone clarify? the difference relates in part to the slightly different regular expressions for categories and custom taxonomies that turn up in rewrite rules, but I think it goes deeper than that, too. thanks." enhancement closed normal Taxonomy normal duplicate
