php - WordPress分类页面按月筛选当前分类文章

Question

在category.php页面使用了小工具，文章归档，就可以按月筛选文章。

问题：这个筛选是全站文章，怎么只筛选当前分类下的文章(不用小工具也可以，只要实现)

Answer 1

    add_filter('getarchives_where','current_category_posts_where');

    function current_category_posts_where($where){
        if(!is_category())
            return;

        $category = get_the_category();
        $term_taxonomy_id = $category[0]->term_taxonomy_id;


        global $wpdb;
        return $where." AND {$wpdb->term_relationships}.term_taxonomy_id = {$term_taxonomy_id}";

    }

    add_filter('getarchives_join','current_category_posts_join');

    function current_category_posts_join(){
        if(!is_category())
            return;

        global $wpdb;
        return "INNER JOIN {$wpdb->term_relationships} on {$wpdb->posts}.ID = {$wpdb->term_relationships}.object_id";

    }

加到主题的functions.php即可.

作用:

访问category archive(in your case, it's category.php)页面时, 如http://www.test.com/category/uncategorized, 只会统计uncategorized下的posts.
