您应该在模块奶嘴prestashop 1.7.5.1中输入尺寸选择

如何解决您应该在模块奶嘴prestashop 1.7.5.1中输入尺寸选择

我正在尝试将尺寸选择放入产品轮播模块中，但我还是无法摆脱。有人可以帮我吗？我得到的错误是：

“通知'：未定义的索引：/web/htdocs/www.mysite.it/home/var/cache/prod/smarty/compile / .....中的id_attribute_group”。

我知道要查看这些变量，我必须在模块中对其进行声明，我已经尝试了各种方法，但我做不到。多亏有人帮我。

我相信这是加载产品特征的功能

这是我在tpl中用于查看相对于尺寸的选择的代码
