如何更新CodeIgniter中的購物車數量？

Question

我想更新購物車的數量。我已經谷歌很多，但無法做到這一點。

最大的頁面顯示我不想要的。確切的解決方案，我沒有得到。希望我能來到這裏。請幫助我做到這一點。這是我的查看頁面。

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

這裏是CONTROLER。

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');

    $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,

       '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); 
} 

請幫我怎麼更新購物車的數量。提前致謝。

Answer 1

要更新車編號：

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"; 
       } 

} 

從購物車中刪除項目：

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