Prestashop:循环 $product->save() 方法 [英] Prestashop : loop on $product->save() method

问题描述

我正在为 Prestashop 创建一个模块，它需要在每次更改产品时重新计算价格.这是我的代码:

I'm creating a module for Prestashop and it need at each change on a product to recalculate the price. This is my code :

public function hookActionProductUpdate($params)
{
    if ($this->context->controller->controller_type == 'front')
        return ;
    $id = $params['id_product'];
    $po = new Product($id);
    $cats = Product::getProductCategories($po->id);
    foreach ($cats as $cat)
    {   
        if ($cat == "49")
        {
            $ok = 1;
            break 1;
        }
        else
            $ok = 0;
    }
    if ($ok == 0)
        return 0;
    $po->price_tax_exc = $this->CalculatePrice($po);
    var_dump($po->price_tax_exc);
    $po->save(); // THE PROBLEM IS HERE
}

问题是当我点击保存时，我永远不会回到管理员的产品列表.当我用 add() 替换 save() 时，这是同一件事，但它会在循环中创建产品.所以 save() 处于循环中，我不知道为什么...

The problem is when i click on save, i will never go back to the product list on the admin. When I replace save() by add() this is the same thing but it create product in a loop. So save() is in a loop and I don't know why...

推荐答案

您至少可以通过两种方式解决此问题:

You can fix this in at least two ways:

1.

protected $price_updated = false;

public function hookActionProductUpdate($params)
{
   if ($this->price_updated)
      return null;
   .........
   if ($po->save())
      $this->price_updated = true;
}

1. 直接在数据库中更新值(它会再次触发你的钩子).我无法在产品表中找到引用 price_tax_exc 的列，我对价格没有太多经验:( 也许 wholesale_price ?

1. Updating the value directly in the database (it would trigger you hook again). I haven't been able to find column inside product table which refers to price_tax_exc, I don't have much experience with prices :( Maybe wholesale_price ?
