Re: [PHP] help with adding

[Randy Johnson]

Try this:
$num=0;
 for ($i = 1; $i <= $sendnum; $i++)
 {
             $qty = $_POST['qty'.$i];
             $num=$num+ $qty ;
 }
  echo $num;

The code below is echoing the qty correctly (10, 5, 25)
 

for ($i = 1; $i <= $sendnum; $i++)
{
            $qty = $_POST['qty'.$i];
            echo $qty . '<br />';
}
 

The question is, how would I take add each of these numbers (10+5+25)?
 

Any help is appreciated.
