使用cakephp将复选框保存到单独的表

我有一些空间用来存放可能会产生费用的事件和项目

在后端，我想添加一个空间和可能的费用，这样我就有了一个表单，其中有多个选择这些费用的复选框

我希望它将事件空间ID写入facility_event_spaces_ID列，并将费用写入我的“event_charges”表中的facility_event_charges_ID列

它没有把任何东西保存到我的桌子上，活动费用。 我可能有一些不正确的模型或控制器或两者。任何cakephp大师都有建议吗

我们正在运行CakePHP1.3。谢谢

此外，这是设施费用表

我发现将数据保存到单独表格的一种方法是：

$maxId = $this->FacilityEventSpace->getMaxId();
                    // routines for Charges
                    $charges = $this->data['FacilityEventSpace']['charge'];
                    $n = 0;
                    foreach ($charges as $key => $cost) {

                        $charge = array('EventCharge'=>array(
                        'id'=>'',
                        'facility_event_spaces_id'=>$maxId[0][0]['max(id)'],
                        'facility_event_charges_id'=>$cost
                        )
                        );
                        $this->EventCharge->save($charge['EventCharge']);
                        $n = $n + 1;
                    } // end charges

由于我的复选框来自一个单独的表，“设施\事件\费用”和那些“选中”的将保存到另一个表，“事件\费用”如何在我的edit.ctp文件中呈现，所有复选框包括那些选中的复选框？因为我的复选框来自一个单独的表，“设施\事件\费用”和那些被选中的“选中”保存到另一个表，“事件费用”如何在我的edit.ctp文件中呈现所有复选框，包括选中的复选框？
