WP\\u Term对象中的“parent”和“category\\u parent”有什么区别?例如:
[1] => WP_Term Object
(
[term_id] => 24
[name] => Essential Oils
[slug] => essential-oils
[term_group] => 0
[term_taxonomy_id] => 24
[taxonomy] => category
[description] =>
[parent] => 22
[count] => 14
[filter] => raw
[cat_ID] => 24
[category_count] => 14
[category_description] =>
[cat_name] => Essential Oils
[category_nicename] => essential-oils
[category_parent] => 22
)
