To update cart Item :
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";
}
}
To remove the item from cart :
function deleteCartItem(){
$row_id = $this->input->post('row_id',TRUE);
if ($rowid) {
return $this->cart->remove($rowid);
}
}
