保存する前に、投稿されたデータを操作する必要があります。$this->dataはこのような配列です

            [user_id] => 3

)

そして、日を変更して、すべての「サブ配列」にuser_idを挿入する必要があります。

しかし、デバッグのためだけに、beforeSave（）でdebug（$ this-> data）を呼び出すと、結果は空の配列になり、何もできなくなります。

Answer 1

beforeSaveメソッドは、または保存関数に続行できるかどうtrueかを通知するだけであるため、そこにロジックを配置することはできますが、データ自体には影響しません。false

データを変更するには、次のように、保存関数を呼び出す前に、コントローラー関数でデータを（再）設定します。

foreach($this->data['Presence'] as $key => $data) {
    if(is_array($key)) {
        // This should be a sub-array
        $this->data['Presence'][$key]['day'] = 1; // Set your 'new' day here
        $this->data['Presence'][$key]['user_id'] = 1337; // Set your user id here
    }
}

// Then, afterwards, save the adjusted data array
$this->Presence->save($this->data);
