显示我不想要的最大页数。完全解决方案我没有得到。希望我能来到这里。请帮我做。这是我的查看页面。

**<table class="table table-hover table-bordered table-striped snipcart-details ">    <thead>
                <tr>

这是控制器。

    public function index()
{   
    $data['basicinfo']          = $this->M_cloud->basicall('basic_info');
    $where                      = array('status' => 1);
    $data['categoryinfo']       = $this->M_cloud->categoryinfo('item_manage', $where);
    $data['rows']               = count($this->cart->contents());       
    $data['userid']             = $this->session->userdata('user_id');      
    $data['subcategoryinfo']  = $this->M_cloud->findAll2('sub_category', array('status' => 1));     
    $data['menuinformation']    = $this->M_cloud->findReport('our_service', array('serviceType'=> 2), 'menuname asc');
    $data['menuservice']        = $this->M_cloud->findReport('our_service', array('serviceType'=> 1), 'menuname asc');      
    $data['socialmedia']        = $this->M_cloud->findAll('social_tbl', 'name asc');
    $data['newsinfo']           = $this->M_cloud->findAll('news_table', 'newstitle DESC');  
    $this->load->view('cartPage', $data);       
}

    public function buy()
{   
    $proId = $this->input->post('proId');
    $Qty   = $this->input->post('Qty');
    $prosize = $this->input->post('prosize');       
    $result = $this->M_cloud->find('product_manage', array('proid' => $proId));     
    $data2 = array(
                'id'                    => $proId,
                'qty'                   => $Qty,
                'name'                  => $result->proName,
                'price'                 => $result->price,
                'prosize'               => $prosize,
                'productImage'          => $result->proimg1,
                'product_code'          => $result->procode                 
            );  
    $this->cart->insert($data2);        
    redirect('cart');   
}

public function deleteCartItem() {
    $row_id              = $this->input->post('row_id');
    $data = array(
        'rowid'   => $row_id,
        'qty'     => 0
    );
    $this->cart->update($data);
}

请帮我更新购物车数量。在此先感谢。

更新购物车项目：

function updateCartItem(){
      $data=array(
             'rowid'=>$this->input->post('rowid',TRUE),
             'qty'=> $this->input->post('quantity',TRUE)
              );

                if ($this->cart->update($data)) {
                 echo "Success";         
                }else{
                     echo "Faliure";
                }

}

要从购物车中删除商品：

function deleteCartItem(){
$row_id = $this->input->post('row_id',TRUE);
  if ($rowid) {
            return $this->cart->remove($rowid);
        }
}

如何在CodeIgniter中更新购物车数量？
