How to make this php opencart 2.0 compatible? How to implement SQL CASE for calculation purpose -


i found code on opencart forum qphoria. seems 1.x.x know right way opencart 2.0?

function recalculateprice() { $response =& $this->locator->get('response'); $database =& $this->locator->get('database'); $url      =& $this->locator->get('url'); $products= $database->getrows("select product_id, price product"); foreach ($products $product) { $sql = "update product set price = '?'  product_id='?'"; $database->query($database->parse($sql,($product['price'] - $product['price']  * 0.02)), $product['product_id'])); }  $response->redirect($url->ssl('product'));         }

what want calculate query. thought in part.

example fields:

$product['wholesale'] $product['cost 1'] $product['cost 2'] $product['cost 3'] $product['cost 4'] $product['minimum_profit']  (cash) $product['margin']  $database->query($database->parse($sql, ($product['wholesale']  +$product['cost 1'] + $product['cost 2'] + $product['cost 3'] +  $product['cost 4'] ) * (($product['margin'] / 100) + 1)) ,  $product['product_id']));

what need if / else statement (($product['margin'] / 100) + 1))

if (($product['margin'] / 100) + 1)) < $product['minimum_profit']   $product['margin'] = $product['minimum_profit']  else $product['margin'] = (($product['margin'] / 100) + 1))

but how mysql? know how write ternary clueless how in mysql.
