Question

我尝试提取并在页面上显示K2store购物车页面中的echo产品代码字段（Joomla的K2商店扩展名），但没有成功。正确的价值是＆＃34; product_code＆＃34;或＆＃34;代码＆＃34; （是相同的值）：26910。

两者＆＃34; echo $ item-＆gt; product_name＆＃34;和＆＃34; echo $ item-＆gt; product_id＆＃34;有效，但＆＃34; echo $ item-＆gt; code＆＃34;和＆＃34; echo $ item-＆gt; product_code＆＃34;返回NULL。

var_dump($item)告诉我这个：
