CakePHP 2 beforeSave（）不工作

我必须在保存之前处理发布的数据。 $this->data是这样的数组

Array

我必须修改日期并在每个“子数组”中插入用户id

但是，当我调用beforeSave（）时，只是为了调试，debug（$this->data）的结果是一个空数组，我什么也做不了。

beforeSave方法应该只返回

true

或

false

，告诉save函数它是否可以继续，所以你只能将逻辑放在那里，而不会影响数据本身

要修改数据，只需在调用save函数之前在控制器函数中（重新）设置它，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);

在“添加控制器”功能中实现所有这些功能可以使其正常工作，但根据MVC这样做是否正确？只是说，您可以（并且根据MVC，您可能应该）在保存之前修改数据。@luisclement如果您重新设置

$this->data

数组的任何键，您是对的，它将按此方式保存。在“添加控制器”函数中使所有这些都正常工作，但根据MVC这样做是否正确？只是说，您可以（并且根据MVC，您可能应该）在保存之前修改数据。@LuisClemente如果您重新设置
