        foreach ($cart as $item){
        $order_detail = array(
            'tblItemsID' => $item['id'],
            'tblLoginID' => $this -> session -> userdata('user_id'),

         $this->db->insert('tblShoppingCart', $order_detail);
         }
     }  
  }              

}

Note:In product_controller.php i coded button to copy cart items to another table. on button click event i wrote in jquery ajax below

jquery Ajax:

<script>
$(document).ready(function(){
$('.add_cart').click(function(){
var product_id=$(this).data("productid");
var product_name=$(this).data("productname");
var product_price=$(this).data("price");
var quantity=$('#' + product_id).val();
if(quantity != '' && quantity >0)
{
$.ajax({
url:"<?php echo base_url();?>products/add",
method:"POST",
data:{product_id:product_id,product_name:product_name,product_price:product_price ,quantity :quantity},
success:function(data)
{
alert("Product Added into cart");
$('#cart_details').html(data);
$('#' + product_id).val('');
}
});
}
else
{
alert("Please Enter Quantity");
}
});
$('#cart_details').load("<?php echo base_url();?>products/load");
 $(document).on('click','.remove_inventory',function(){
        var row_id = $(this).attr("id");
        if(confirm("Are you sure you want to delete item")){
            $.ajax({
                url:"<?php echo base_url();?>users/remove",
                method:"POST",
                data:{row_id:row_id},
                success:function(data)
                {
                alert("Product remove fromm cart");
                $('#cart_details').html(data);
                }
            });
        }else{
            return false;
        }
    });
$(document).on('click','#clear_cart',function(){

if(confirm("Are you sure you want to delete item"))
{
$.ajax({
url:"<?php echo base_url();?>products/clear",

success:function(data)
{
alert("Are you sure you want clear cart?");
$('#cart_details').html(data);

}
});
}
else{
return false;
}
});
$(document).on('click','.basket',function(){

if(confirm("Are you sure you want to delete item"))
{
$.ajax({
url:"<?php echo base_url();?>products/basket",
method:"POST",
success:function(data)
{
alert("Are you sure?");
window.location="users/basket";

}
});
}
else{
return false;
}
});

});

</script>

    Use this code on your needed redirect place: where you will retrieve the response via ajax success response (date);
    before that you will return the value in server side which mean controller.

    $.ajax({
    url:"<?php echo base_url();?>products/basket",
    method:"POST",
    success:function(data)
    {
    alert("Are you sure?");
    location.href = data.url_path;
    
    }
    });
