Codeigniter中的购物车无法正常工作

Question

I am new to codeigniter framework I have created one cart using codeigniter library. The problem of the cart is that when I want to remove the product from the cart then the product is not removing immediately from the cart rather i have to press F5 ie refresh the whole page then it appears correctly does there is any problem with the codeigniter or I am doing any wrong logic.

Following is the cart controller to remove the product from my cart

  function remove($rowid) {
    $data = array(
        'rowid' => $rowid,
        'qty' => 0
    );
    $this->cart->update($data);
    $this->load->view('cart');  
}

Following is the link to remove the product from the cart

 <a href="<?php echo base_url(); ?>cart/remove/<?php echo trim($items['rowid']); ?>">remove</a>

Answer 1

try this. use redirect to redirect page

function remove($rowid) {
    $data = array(
        'rowid' => $rowid,
        'qty' => 0
    );
  $this->cart->update($data);

    redirect(site_url('cart'), 'refresh');
}

Answer 2

Try this may works for you: you should redirect after update your database do not us $this->load

your controller

class Cart extends CI_Controller
  function index(){
    $this->load->view('cart');  
  }
  function remove($rowid) {
    $data = array(
        'rowid' => $rowid,
        'qty' => 0
    );
    $this->cart->update($data);
    redirect('cart', 'refresh');
  }
}

your view:

<a href="<?php echo base_url(); ?>cart/remove/<?php echo trim($items['rowid']); ?>">remove</a>

Answer 3

you are not sending $data to your view. Try to change in your controller

 $this->load->view('cart',$data);
