my client want to be able to buy products with decimal quantity, like 1.5 or 3.5, is there any way to codeigniter’s Shopping Cart class can handle this?

因为现在，如果我尝试放入和十进制数量表示去除逗号，例如，如果我键入1.5，则变为15.

Because right now if i try to put and decimal quantity it remover the comas, exemple, if i type 1.5, it goes as 15.

感谢关注

我通过转到"SYSTEM \ LIBRARIES \ CART.PHP"并更改了第161行来解决此问题:

从这里:

$items['qty'] = trim(preg_replace('/([^0-9])/i', '', $items['qty']));

对此:

$items['qty'] = trim(preg_replace('/([^0-9\.])/i', '', $items['qty']));

这样做，您可以在数量上加上小数.

Doing this, you can add decimals on quantity.
