WordPress : get_queried_object()の返り値のまとめ
Posted by admin at 7:54 日時 2013/09/11
WordPressでfunctions.phpなどあらかじめ分岐されたテンプレートではないPHPでクエリーオブジェクトを取得して何かしたいときに、いつもget_queried_objectの挙動が不安なのでメモってみた。

所感
- WP_Postオブジェクトは便利だ。post_typeパラメーターで見分けがつく
- カテゴリーだけ後方互換性のためかオブジェクトの内容が違う。重複しているだけなので category_nicename や cat_name パラメーターは使わないほうが汎用性が高い
- stdClassで返ってくるのは今のところタクソノミーと投稿タイプの2パターンがあり得る。stdClassやめてくれマジで
- タクソノミーが絡まないアーカイブや検索結果がNULLなのはこういうもんだと思うしかなさそうだ
- get_queried_object_id() の返り値は、post_id または term_id でそれ以外は0。投稿タイプアーカイブは get_queried_object() だとオブジェクトが返ってくるが get_queried_object_id() は無反応なので注意
ということで考えられる妥当な条件分岐（なげえ）
$obj = get_queried_object(); if (is_object($obj)) { if ($obj instanceof WP_Post) { echo '投稿'; if ( is_front_page() ) { echo '表示設定で選択したフロントページ'; } elseif( is_home() ) { echo '表示設定で選択した投稿ページ'; } } elseif ($obj instanceof stdClass) { // ここ何とかして！ if ( isset($obj->taxonomy) ) { echo 'タクソノミー'; } elseif ( isset($obj->labels) ) { echo '投稿タイプ'; } } } elseif( is_archive() ) { echo 'タクソノミー、投稿タイプ以外のアーカイブ'; } elseif( is_search() ) { echo '検索結果'; } elseif( is_home() ) { echo '通常のホーム'; } else { echo '404'; } うーん、素直に条件分岐関数を使ったほうがマシっぽいですな。
