如何定義變量並在smarty中回顯它們？

Question

我已經添加了此代碼到一個Smarty的模板文件：

$totalearnings = {$pendingcommissions|replace:' USD':''|replace:'$':''} + {$balance|replace:' USD':''|replace:'$':''} + {$withdrawn|replace:' USD':''|replace:'$':''}; 
echo $totalearnings; 

這是它是如何顯示在頁面上：

$totalearnings = 0.00 + 1010.00 + 2000.00; 
echo $totalearnings; 

究竟是什麼，我需要改變，以使此代碼工作？ $totalearnings應添加數字，而不是隻在頁面上顯示公式...

試試這個使用{assign var="name" value="Bob"}

{assign var="p" value=$pendingcommissions|replace:' USD':''|replace:'$':'' } 

{assign var="b" value=$balance|replace:' USD':''|replace:'$':'' } 

{assign var="w" value=$withdrawn|replace:' USD':''|replace:'$':'' } 

{assign var="totalearnings" value=0} 

{assign var="totalearnings" value=$totalearnings+$p+$b+$w} 

{$totalearnings} 

{assign}
