是否可以在CodeIgniter中使用id而不是rowid从购物车中删除产品？

I an using CodeIgniter shopping cart. I am able to add the product in the cart and remove is also working.

Now, My issue is, Is it possible to remove the product using id instated of rowid.

Why I am doing with id because I want to give the customer to add the same product only once. The same product can't add more than one time. So once the product is added in the cart then I am changing the button from add to cart to remove using jQuery. So this scenario is working for me but the issue is when I refresh the page then my button is showing "Add to cart" again.

So I tried to solve, if the product is in the cart and the user refreshes the page then still show the remove button.

So I tried

if (in_array($activity_name_id, array_column($this->cart->contents(), 'id'))) {?>
<button type="button" name="remove" class="btn btn-danger btn-xs remove_inventory" id="1">Remove</button>
<?php }else{?>
<button type="button" name="renew" class="btn btn-success add_cart" data-productname="<?php echo $activity_name; ?>" data-price="" data-productid="<?php echo $activity_name_id;?>"/>Add to cart</button><?php }?>

I tried above code on view page, if the user refreshes the page and product in a cart then it will display the remove button.

So everything is working but the issue is, if I click on remove button then the product is not removing from the cart because I am calling the id. Also how to display again add to cart button after removing the g product.

that's the reason I want to remove the product from the cart using id.

Let me know I am on the right path or not.

Remove from cart

$(document).on('click', '.remove_inventory', function(){
  var row_id = $(this).attr("id");
  if(confirm("Are you sure you want to remove this?"))
  {
   $.ajax({
    url:"<?php echo base_url(); ?>Member_controller/Removecart",
    method:"POST",
    data:{row_id:row_id},
    success:function(data)
    {
     alert("Product removed from Cart");
    $('#totalDetails').html(obj.cart_total);          
    $('#totalQty').html("Total items:"+obj.totalQty);
    reloadCart();
    }
   });
  }
  else
  {
   return false;
  }
 });

Remove code

public function Removecart(){
 $row_id = $_POST["row_id"];
  $data = array(
   'rowid'  => $row_id,
   'qty'  => 0
  );
  $this->cart->update($data);
}

jQuery

$(document).ready(function(){

 $('.add_cart').click(function(){
  var product_name = $(this).data("productname");
  var product_id = $(this).data("productid");
  var product_price = $(this).closest('tr').find('.calActivitylPrice').text();
  var quantity =1 //$('#clubmembershipcheckbox').val();

  var changeToRemoveBTNSec = $(this).closest('tr').find('.display_table');

   $.ajax({
    url:"<?php echo base_url(); ?>Member_controller/addToCart",
    method:"POST",
    data:{product_id:product_id, product_name:product_name, product_price:product_price,quantity:quantity},
    success:function(data)
    {
    var obj = JSON.parse(data);


    $(changeToRemoveBTNSec).html('<button type="button" name="remove" class="btn btn-danger btn-xs remove_inventory" id="'+obj.removebtn+'">Remove</button>');

   // $('#subtotal_details').html('Total cost: INR ' +obj.subtotal);
     $('#totalDetails').html(obj.cart_total);          
     $('#totalQty').html(obj.totalQty);
    }
   });

 });

});

Would you help me out in this issue?
