Question

如果我的数据库中存在ID，我想更新记录。如果ID不存在则创建记录。这是我的Controller添加功能中的代码

public function add () {

    $googleCategory = $this->request->data;

    foreach ($googleCategory as $key => $value) {
        if(empty($value['category'])){
            unset($value);
        }

        $this->AccountShopMeta->create();

        $data['shop_id'] = $value['shop_id'];
        $data['name'] = $value['category'];
        $data['value'] = $value['url_key'];
        $data['tag'] = '';

        if($this->AccountShopMeta->save($data)){
            $account_shop_meta = $this->AccountShopMeta->read();
            $this->set($account_shop_meta);
            $this->set('_serialize', array_keys($account_shop_meta));
        }
    }

}

如果我明白你的要求可能会对你有帮助。不要使用Create。如果id存在于给定数组中，则将自动对该ID进行更新。否则将创建新行。

public function add () {

$googleCategory = $this->request->data;

foreach ($googleCategory as $key => $value) {
    if(empty($value['category'])){
        unset($value);
    }
   if(!empty($value[id])){
      $data['id']=$value[id];
   }


    $data['shop_id'] = $value['shop_id'];
    $data['name'] = $value['category'];
    $data['value'] = $value['url_key'];
    $data['tag'] = '';

    if($this->AccountShopMeta->save($data)){
        $account_shop_meta = $this->AccountShopMeta->read();
        $this->set($account_shop_meta);
        $this->set('_serialize', array_keys($account_shop_meta));
    }
}

}

我想如果id不存在，它就会变为空，在这种情况下，在foreach中添加以下条件，至少在上面保存动作：

foreach ($googleCategory as $key => $value) {
  if(isset($value['id']) && !empty($value['id'])){
     $this->AccountShopMeta->id = $value['id'];
     // your remaining code within loop here
     //
  }
}

如果存在，请不要忘记为您的视图（表单）发送id的数据..

Cakephp如果id存在update，则create
