カテゴリに対応したタグのみを表示する
個別ページを表示させた時に、違うカテゴリのタグも表示されてしまうので
個別ページのカテゴリーにあったタグのみを表示する方法
日記のようないろいろなカテゴリーがあるブログにはいいと思います
functions.phpに追加します function my_category_tag_cloud($args) { $defaults = array( 'smallest' => 8, 'largest' => 22, 'unit' => 'pt', 'number' => 45, 'format' => 'flat', 'separator' => "\n", 'orderby' => 'name', 'order' => 'ASC', 'exclude' => '', 'include' => '', 'link' => 'view', 'taxonomy' => 'post_tag', 'echo' => true ); $args = wp_parse_args( $args, $defaults ); global $wpdb; $query = " SELECT DISTINCT terms2.term_id as term_id, terms2.name as name, t2.count as count FROM $wpdb->posts as p1 LEFT JOIN $wpdb->term_relationships as r1 ON p1.ID = r1.object_ID LEFT JOIN $wpdb->term_taxonomy as t1 ON r1.term_taxonomy_id = t1.term_taxonomy_id LEFT JOIN $wpdb->terms as terms1 ON t1.term_id = terms1.term_id, $wpdb->posts as p2 LEFT JOIN $wpdb->term_relationships as r2 ON p2.ID = r2.object_ID LEFT JOIN $wpdb->term_taxonomy as t2 ON r2.term_taxonomy_id = t2.term_taxonomy_id LEFT JOIN $wpdb->terms as terms2 ON t2.term_id = terms2.term_id WHERE t1.taxonomy = 'category' AND p1.post_status = 'publish' AND terms1.term_id = " . $args['cat'] .
