Given is a template like this:

Code:

<table>

<tfoot>
<tr>
<td>Avg.</td>
<td>{$average}</td>
</tr>
</tfoot>

<tbody>
{foreach $data as $item}
<tr>
<td>{$item->Name()}</td>
<td>{$item->Value()}</td>
</tr>
{/foreach}
</tbody>

</table>

The problem is to compute $average. Of course this could be done by the application, but the real-world example is more complicated and - in my opinion - it is not the job of the application logic to calculate presentation details (and nobody knows which figures people want to see next in their reports anyway).

Now of course Smarty can easily calculate $average, but due to the weird HTML-sequence "footer before body" the result is needed before it is available. And running

Code:

{foreach $data as $item}{/foreach}

twice does not seem to be good practice either.

Is there something like the way to go in order to swap footer and body between template and actual output?
