让 WordPress 页面支持添加分类及标签

默认WordPress页面不支持选择分类和添加标签，可以通过下面的方法为页面添加分类及标签。文章源自知更鸟-https://zmingcx.com/create-and-assign-categories-for-pages.html

将下面代码添加到当前主题函数模板functions.php中：文章源自知更鸟-https://zmingcx.com/create-and-assign-categories-for-pages.html

function san_add_taxonomies_to_pages() {
	register_taxonomy_for_object_type( 'post_tag', 'page' );
	register_taxonomy_for_object_type( 'category', 'page' );
}

add_action( 'init', 'san_add_taxonomies_to_pages' );
if ( ! is_admin() ) {
	add_action( 'pre_get_posts', 'san_category_and_tag_archives' );
}

function san_category_and_tag_archives( $wp_query ) {
	$my_san_post_array = array('post','page');
	if ( $wp_query->get( 'category_name' ) || $wp_query->get( 'cat' ) )
		$wp_query->set( 'post_type', $my_san_post_array );

	if ( $wp_query->get( 'tag' ) )
		$wp_query->set( 'post_type', $my_san_post_array );
}

之后，页面与正常文章一样可以选择添加分类和标签了。文章源自知更鸟-https://zmingcx.com/create-and-assign-categories-for-pages.html
