Wordpressのグリッドビューにカスタム投稿タイプの値を表示する

Question

図のようにWordPressでカスタム投稿タイプを作成しました。

 私が欲しいのは、管理パネルのグリッド表示でこのカスタム投稿に追加された値を表示することです。これで、管理パネルには投稿のタイトル、日付、コメントの画像しか表示されなくなりましたが、カスタム投稿に入力されたPair2、buy sell、activityフィールドの値を表示したいと思います。私はたくさん検索しましたが、解決策が見つかりませんでした。 WordPressでどうすればいいの？

これが私のカスタム投稿の作り方です

manage_edit-${post_type}_columnsフィルタをmanage_${post_type}_posts_custom_columnアクションと組み合わせて使用​​できます。 Codex内の example を確認して、ステップごとに分解してください。

まず、登録したカスタム投稿タイプの正しい名前を必ず入力してください。投稿タイプをquoteという名前で登録しました。

次に、追加する列を定義し（set_custom_edit_quote_columnsを参照）、適切な値を割り当てます（custom_quote_columnsを参照）。

あなたはこのようなものになってしまうはずです：

add_filter( 'manage_edit-quote_columns', 'set_custom_edit_quote_columns' );
add_action( 'manage_quote_posts_custom_column' , 'custom_quote_columns', 10, 2 );

function set_custom_edit_quote_columns( $columns ) {

    $columns['pair'] = __( 'Pair' );
    $columns['buysell'] = __( 'Buy Sell' );
    $columns['activity'] = __( 'Activity' );

    $columns['entryprice'] = __( 'Entry Price' );
    $columns['stoploss'] = __( 'Stop Loss' );
    $columns['takeprofit'] = __( 'Take Profit' );

    return $columns;
}

function custom_quote_columns( $column, $post_id ) {
    switch ( $column ) {

        case 'pair' :
            echo get_post_meta( $post_id, '_quote_post_pairname', true );
            break;

        case 'buysell' :
            echo get_post_meta( $post_id, '_quote_post_buysell', true );
            break;

        case 'activity' :
            echo get_post_meta( $post_id, '_quote_post_activity', true );
            break;

        case 'entryprice' :
            echo get_post_meta( $post_id, '_quote_post_entryprice', true );
            break;

        case 'stoploss' :
            echo get_post_meta( $post_id, '_quote_post_stoploss', true );
            break;

        case 'takeprofit' :
            echo get_post_meta( $post_id, '_quote_post_takeprofit', true );
            break;

    }
}
