您很可能会在某个阶段希望以编程方式为具有各种分类法的多个自定义帖子类型生成重写规则。你可以手动操作，但那并不有趣。让我们使用自动重写规则生成器。

下面的函数将post类型作为第一个参数，并为其每个分类创建一系列重写规则。该函数还包括一个可选的第二个参数$query\\u vars，它是您可能要为其添加重写规则的任何非分类查询变量的数组。它非常适合为高级元数据查询添加查询变量。例如，我们的事件发布类型可以使用日期查询变量。

/**
 * Generates all the rewrite rules for a given post type.
 *
 * The rewrite rules allow a post type to be filtered by all possible combinations & permutations
 * of taxonomies that apply to the specified post type and additional query_vars specified with
 * the $query_vars parameter.
 *
 * Must be called from a function hooked to the \'generate_rewrite_rules\' action so that the global
 * $wp_rewrite->preg_index function returns the correct value.
 *
 * @param string|object $post_type The post type for which you wish to create the rewrite rules
 * @param array $query_vars optional Non-taxonomy query vars you wish to create rewrite rules for. Rules will be created to capture any single string for the query_var, that is, a rule of the form \'/query_var/(.+)/\'
