wP_List_Tableのカスタム一括アクションの作成方法（コアクラス）
私はWP_List_Tableクラスを使用しています、そして私はこのような行動へのリンクを加えました：
function get_bulk_actions() {
$actions = array();
$actions['approv'] ='<a href="#">'.__( 'Approve' ).'</a>';
$actions['reject'] = '<a href="#">'.__( 'Reject' ).'</a>';
$actions['delete'] = '<a href="#">'.__( 'Delete' ).'</a>';
$actions['view'] = '<a href="#">'.__( 'View' ).'</a>';
return $actions;
}
それから私はこのようにdisplay_row()関数でそれらを表示します：
$actions = $this->get_bulk_actions();
echo $this->row_actions( $actions );
今私は作成したそれらのリンクにカスタムアクションを追加する方法を疑問に思っています。変数をページに送信できる場所はありますか。これらのリンクのDB処理を行い、私がアクションを実行する前に作成されたWP_List_Tableを再作成するため。

これがWP_List_Tableクラスのフルコードです。
