Hi, I need your with the EVAL function.

In PHP I have a list of 27 fields, like this:

$advert['act1'] = 'foo';
$advert['act2'] = 'bar';
....
$advert['act26'] = 'doo';
$advert['act27'] = 'da';

I know this smells like it should be an array, but for
particular reasons it is not. So the template looks
like this:
{$advert.act1}<br>
{$advert.act2}<br>
....
{$advert.act26}<br>
{$advert.act27}<br>

Can I replace this with a loop? Something like:
{section name=foo start=1 loop=27}
{eval var="\$advert.act`$smarty.section.foo.index`"}
<br>
{/section}

The code above does not work, by the way. The line
{eval var="\$advert.act`$smarty.section.foo.index`"}
produces:
$advert.act1

If I add braces:
{eval var="{\$advert.act`$smarty.section.foo.index`}"}
it displays:
{\.act1"}

So I must be missing something here.

Thanks,
Mike

What is wrong with:
{foreach from=$advert item=ad }
{$ad}<br>
{/foreach}

Hi Alain,

A bit more background: The associative PHP array is
actually the representation of a database row. As
such, it has many other fields besides act1, act2 etc.

Thats why I can't use the foreach loop.

Thanks,
Mike.
