Admin Columnsの便利なadd on (part2)

はじめに

Admin Columnsの便利なadd on

前回の続きで
Admin Columns Proで作成した独自カラムに
独自ソートを追加する方法

add onで作成した独自カラムに独自ソートを追加

前回と同様、githubで公開されているので、
使い方について少し説明しようと思います。

ソート機能部分を書き換えてみる。
今回、投稿ID順にソートするように処理を記載しました。

/**
 * Sorting class. Adds sorting functionality to the column.
 */
class ACP_Sorting_Model_COLUMN_NAME extends ACP_Sorting_Model {

    /**
     * (Optional) Put all the sorting logic here. You can remove this function if you want to sort by raw value only.
     *
     * @return array
     */
    public function get_sorting_vars() {
        $post_ids = [];
        $posts    = get_posts();
        foreach ( $posts as $post ) {
            //postのIDのみを格納
            $post_ids[ $post->ID ] = $post->ID;
        }
        //postのIDをソートして返す
        return [
            'ids' => $this->sort( $post_ids ),
        ];

    }

}

表示させて、
昇順ソートさせてみました。

降順ソートさせてみました。
