我必须在保存之前操纵发布的数据。 $ this-＆gt; data是一个像这样的数组
Array

我必须修改日期并在每个“子数组”中插入user_id。
但是当我打电话时，只是为了调试，在我的beforeSave（）上调试（$ this-＆gt;数据），结果是一个空数组，我什么都不做。
答案 0 :(得分：1)
beforeSave方法应该只返回true或false来告诉save函数它是否可以继续，所以你只能把逻辑放在那里，但不会影响数据本身。
要修改数据，在调用保存功能之前，只需（重新）设置控制器功能，例如：
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);
