cakephp使用foreach（）保存数据数组

我试图保存来自多个同名输入的大小数据

问题是我无法保存数据。只有最后一个值“size”保存在数据库中

if ($this->EquipmentType->save($this->request->data['EquipmentType'], false)) {
    $id = $this->EquipmentType->getLastInsertId();
    $this->loadModel('EquipmentTypesSize');
    $sizesArray = $this->request->data['EquipmentType']['size'];
    foreach($sizesArray as $val){
        $data[] = array('EquipmentTypesSize' => array('sizes' =>  $val));
    }
    $this->request->data['EquipmentTypesSize']['equipment_type_id'] = $id;
    $this->EquipmentTypesSize->set($this->request->data);
    $this->EquipmentTypesSize->save($this->request->data['EquipmentTypesSize']);
    $this->Session->setFlash('Equipment type has been added successfully ', 'default', 'success');
    $this->redirect(array('controller' => 'equipments', 'action' => 'listequipmenttypes', 'admin' => true));
}

我想把这个保存为

equipment_type_id | size1
equipment_type_id | size2
equipment_type_id | size3

有几个问题——Kai提到的调用

create

就是其中之一

首先，这里是您的代码，但我在看到明显问题的地方添加了注释（我并没有抓住所有问题）

最后，有两件事：

实际上，您应该尽可能多地将这些逻辑应用到您的

设备类型

模型中。因此，您可以在

EquipmentType

模型中创建一个

saveWithSizes

方法来保存大部分代码

您应该研究Cake的

saveAll

方法（）。理想情况下，您应该设置表单数据，这样您就可以调用saveAll并让Cake自动处理所有数据。然而，对于你的情况来说，这也许是可能的，也可能是不可能的

：“如果要插入新行而不是更新现有行，则应始终首先调用create（）。这样可以避免与回调或其他位置中先前可能的保存调用发生冲突。”：“如果要插入新行而不是更新现有行，则应始终调用create（）首先，这避免了与以前在回调或其他地方可能进行的保存调用发生冲突。”
