Ask a master about the Smarty problem!!!
The following is an array of shopping carts
$carts =array (
1=>array (name=> "Nokia 5510", price=>800, Qty=>2),
3=>array (name=> "Nokia 6610", price=>1800, Qty=>1),
4=>array (name=> "Nokia 7710", price=>2800, Qty=>1),
7=>array (name=> "Nokia 8810", price=>2500, Qty=>5),
}
Use the Smarty Loop, display the shopping cart in tabular form, the table row background color has the rotation effect, the table has the total statistics

Do the addition in the PHP page and pass in the Smarty template. Smarty doesn't seem to be calculating.

Loop Add-out
$sum
$smarty->assign ("sum", $sum);

Total amount: {$sum}
------Solution--------------------
I checked the manual and can calculate

In math [math] {assign var= "foo" value= "' $foo + $bar '"}

Your template can be written like this

HTML Code

            
  
   
          <title>Untitled Document</title>                
  
  {foreach from= $carts key=k item=item0} {if $k% 2} 
    
      {Else} 
    
      {/if} {foreach from= $item 0 item=item1} 
     {/foreach} 
    {Assign var= "sum" value= "' $sum + $item 0.price '"} {/foreach} 
    
            
 
   
   
 
    
 
     
Name
 
     
Price
 
     
Number
 
    
 
    
{$item 1}
 
     
Total amount: {$sum}
 
    
 
   

  
  
    
------Solution--------------------
If you want to do multiplication
{Assign var= "sum" value= "' $sum + $item 0.price* $item 0.qty '"}
