なぜこのエラーが発生しますか？クラスstdClassのオブジェクトをintに変換できませんでしたか？

Question

私は写真を添付し​​たエラーメッセージが表示されていますが、ビューに表示されていない "出席"部分以外はすべて正常に動作しています。問題点はわかりません。それを見ていない、私が間違っている場所を教えてください。ありがとうございました。

Answer 1

この$data_view= $query->row();を行う際に、$data_viewが対象となります。それはvar_dump($data_view)で確認できます。 $data_viewは整数ではないため、if($data_view > 0)のように使用することはできません。 $data_viewにデータが含まれているかどうかを確認する場合は、if(count($data_view) > 0)のように確認できます。 が必要です。 :)
