Smile 

Hi guys Big Grin i need to make this query UPDATE `php_items` SET `item_quantity` = `item_quantity` - 10 WHERE `item_id` = 1 using the active record class and i have tried this:

$quantity = -10;
$data = array(
'item_quantity' => 'item_quantity'.$quantity,
);

$this->db->where('item_id', 1);
$this->db->update('php_items', $data);

But it returns: UPDATE `php_items` SET `item_quantity` = 'item_quantity-10' WHERE `item_id` = 1 What am i doind wrong?
