产品 Table 内联编辑在 opencart 中不起作用 - 在 null 时调用成员函数 post()

Question

产品table 内联编辑在 opencart 2.3.0.2 中不起作用。我使用 ajax 格式获取编辑后的 table 值，并尝试在控制器中移动，但它不起作用。它显示 Fatal error: Call to a member function post() on null。请参阅下面的代码。给出任何解决方案。

public function update() 

    {
            $product_id = $this->request->post['product_id'];
            $column = $this->request->post['column'];
            $editableobj = trim($this->request->post['value']);   
            $this->model_catalog_product->updateProduct($product_id, $column, $editableobj);

    }

访问 post 值 [''] 像这样括号不像这样 ('')
