我必须在保存之前处理发布的数据。$this->data 是这样的数组

Array

我必须修改日期并将 user_id 插入每个“子数组”中。

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

Answer 1

beforeSave 方法应该只返回true或false告诉保存函数是否可以继续，因此您只能将逻辑放在那里，但不会影响数据本身。

要修改数据，只需在调用保存函数之前（重新）在控制器函数中设置它，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);
