新しい投稿にデフォルトのmeta_valueを追加する
ユーザーがフロントエンドから投稿を作成および更新できるようにするページテンプレートがあります。私はまた2つのプラグインを使用しています。1つはユーザーが1-5の星から投稿を評価することを可能にし、もう1つはそれらが投稿をお気に入りにできるようにします。
私はまた、ユーザーが日付/カテゴリ/投稿タイプ/ etcで投稿を並べ替えることを切り替えることを可能にするページを持っています。あなたはここでページを見ることができます： http://www.theseattlevine.com/the-Vine/
問題は、私が投稿を星の評価またはお気に入りの数でソートした場合、Wordpressはそのメタ値を持つ投稿のみを返し、まだ受け取っていない投稿は表示されないということです。それが言われているので、私は2つのうち1つをする必要があります：
- 投稿が作成されたときにメタ値をデフォルト値に自動的に設定します。
- まだ値がない投稿も表示するようにwp_queryを変更します。
誰でも私がこれらのことのどちらかをすることができる方法を知っていますか？私は＃1を好むが、どちらでもうまくいくだろう。
これが便利な場合は、ここにページテンプレートコードがあります。
