get_taxonomy()

💡 云策文档标注

概述

get_taxonomy() 函数用于检索指定分类法的 WP_Taxonomy 对象。它首先验证分类法是否存在，然后返回对应的对象或 false。

关键要点

参数：$taxonomy（字符串，必需），指定要返回的分类法名称。
返回值：WP_Taxonomy 对象或 false（如果分类法不存在）。
注意：此函数不返回分类法下的术语列表；如需术语，应使用 get_term() 或 wp_list_categories()。
内部实现：通过全局变量 $wp_taxonomies 和 taxonomy_exists() 检查来获取对象。

代码示例

$rental_features = get_taxonomy( 'features' );
print_r( $rental_features );

注意事项

确保分类法已注册，否则返回 false。
适用于自定义分类法，如示例中的 'features' 关联自定义文章类型 'rentals'。

📄 原文内容
