Try this one
// set $flag default value to true for inserting item to the cart session
$insert_new = TRUE;
$bag = $this->cart->contents();
foreach ($bag as $item) {
// check product id in session, if exist update the quantity
if ( $item['id'] == '1' ) { // Set value to your variable
$data = array('rowid'=>$item['rowid'],'qty'=>++$item['qty']);
$this->cart->update($data);
// set $insert_new value to False
$insert_new = FALSE;
}
}
// if $insert_new value is true, insert the item as new item in the cart
if ($insert_new) {
$data = array(
'id' => 1,
'qty' => 1,
'price' => 40,
'name' => 'Product item'
);
$this->cart->insert($data);
}
