smarty将值从{math} equatio传递给变量

Question

祝大家度过愉快的一天,我有事要问你好,更好地了解这里是我的代码:

{math equation=((($order_total-$commission)+$discount+$delivery_charge)*$rate)}

我希望将其传递给另一个变量,在php中我想要像这样

<?php 
  $var=0
  foreach($result as $resultA){
   $var = $var+((($order_total-$commission)+$discount+$delivery_charge)*$rate);
}
?>

希望你能帮助我们!

如果您正在使用Smarty 3,我强烈建议放弃{math}:

{$order_total = 123}
{$commission = 13}
{$discount = 10}
{$delivery_charge = 20}
{$rate = 1.1}

{$result = 0}
{$result = $result + ($order_total - $commission + $discount + $delivery_charge) * $rate}
{$result}

它具有更好的可读性和更快性(因为表达式实际上是编译的,而不是eval()ed一遍又一遍).

Smarty 2相当于:

{assign var="order_total" value=123}
{assign var="commission" value=13}
{assign var="discount" value=10}
{assign var="delivery_charge" value=20}
{assign var="rate" value=1.1}

{assign var="result" value=0}
{math 
  assign="result"
  equation="result + (order_total - commission + discount + delivery_charge) * rate"
  result=$result
  order_total=$order_total
  commission=$commission
  discount=$discount
  delivery_charge=$delivery_charge
  rate=$rate
}
{$result}

如果有机会升级到Smarty 3 - 那就去吧!
