hookActionProductUpdate 在模块中调用了两次 - hookActionProductUpdate called two times in module

hookActionProductUpdate called two times in module

我正在为我的网站创建一个模块，这里我用hookActionProductUpdate钩子在ps_game_key表中插入了一些值。更新产品时，插入查询将执行两次。插入 SO 2 条记录，而不是插入 1 条记录。这似乎钩住了ActionProductUpdate被调用了两次。请帮忙

 class    customsupplier
{
  public function __construct()
  {
    $this->name = 'customsupplier';
    $this->tab = 'front_office_features';
    $this->version = '1.0';
    $this->author = 'Rex';
    $this->need_instance = 0;
    parent::__construct();
    $this->displayName = $this->l('Custom Supplier');
    $this->description = $this->l('Custom Supplier Module');
 }
public function install()
{
    if (!parent::install() OR
        !$this->alterTable('add') OR            
        !$this->registerHook('actionAdminControllerSetMedia') OR
        !$this->registerHook('actionProductUpdate') OR
        !$this->registerHook('displayAdminProductsExtra'))
        return false;
    return true;
}

 public function hookActionProductUpdate($params)
    {

        Db::getInstance()->insert('game_key', array(
                'id_product' => 89,
                'key_type' =>'test',
                'game_key'      => 'reee',
                'added_date_time'=> 'ssd'
        ),true);
}

}

钩子product update可能会被多次触发，因为有很多地方调用了方法$product->save()。

您始终可以防止以非常简单的方式保存更多内容

protected $isSaved = false;
public function hookActionProductUpdate($params)
{
   if ($this->isSaved)
      return null;
   $isInsert = Db::getInstance()--insert(...);
   if ($isInsert)
      $this->isSaved = true;
}
