Question

我正在使用CI 2.1.3进行购物车项目。这就是add-to-cart的工作原理：调用add_to_cart函数将项目插入购物车，然后重定向到view_cart页面。但购物车没有立即更新。它仅在重新加载页面时更新。为什么呢？

public function add_to_cart($product_id){
        if (isset($product_id)){
            $product = $this->_product_model->get_record_by_id((int)$product_id);
            if (!is_null($product)){
                if (count($this->cart->contents())>0){
                    foreach ($this->cart->contents() as $item){
                        if ($item['id']==$product->id){
                            $data = array('rowid'=>$item['rowid'],'qty'=>++$item['qty']);
                            $this->cart->update($data);
                        }else{
                            $data = array('id'=>$product->id,'qty'=>1,'price'=>$product->price,'name'=>$product->id,'options'=>array('image'=>$product->thumb,'product_name'=>$product->title));
                            $this->cart->insert($data);
                        }
                    }
                }else{
                    $data = array('id'=>$product->id,'qty'=>1,'price'=>$product->price,'name'=>$product->id,'options'=>array('image'=>$product->thumb,'product_name'=>$product->title));
                    $this->cart->insert($data);
                }
                //$this->layout->load('cart/view_cart', $this->data);
                redirect(base_url('view_cart.html'),'location');
            }
        }else{
            $this->layout->load('/product/product_not_found', $this->data);
        }
    }

Answer 1

试试这个：

redirect(base_url('view_cart.html'),'refresh');

Codeigniter购物车刚刚刷新页面后更新
