Как избавиться от ошибки Division by zero

Recommended Posts

Сначала при выборе показать 100 товаров на странице выбрасывало на несуществующую страницу. По совету на одном из форумов отключила сжатие. Теперь все открывается, но сверху вылезает такая ошибка:


Warning: Division by zero in /home/***/***/vqmod/vqcache/vq2-catalog_controller_product_category.php on line 228


Эта строка содержит такой код

'sale'        => '<div style="width: 0px;height: 0px;"><div style="background: url(/image/sale.png);background-repeat: no-repeat;position: absolute;background-size: 100% 100%; color: #fff;padding: 10px 10px;font-weight: bold;font-size: 14px;">' . '-' . round((($result['price'] - $result['special'])/$result['price'])*100, 0) . '%' . '</div></div>',

Как исправить это?

Решено. Ошибка вылезала из-за товаров с нулевой ценой. Поставила цену больше нуля - ошибка исчезла  :-)
