数组，我要修改的日期和插入每一个“子阵列”的USER_ID。

但是，当我打电话，只是为了调试，在我的beforeSave（）调试（$ this-> data）结果是一个空数组，我什么都不能做。

Answer 1

beforeSave方法只应返回true或false来告诉save函数是否可以继续，所以您只能将逻辑放在那里，但不能影响数据本身。

要修改数据，只是（重新）-set它在你的控制器函数调用保存功能，像以前一样：

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);
