"selected" in a loop

[Anonymous]

cool templaet-module, but i've run into a small problem....

i'm building a couple of pages with dropdown-boxes, based on data from a database. I've used the <TMPL_LOOP> to build the dropdown-boxes, but what is the best way to mark one of them as "selected"?

As i've understood, the TMPL_IF can only check boolean values? it could be cool if i were able to do <TMPL_IF NAME=[var-name] VALUE=[value to be checked with]> and the value of [var-name] would be checked agains the [value to be checked with]...if they match => true, if not => false.

Have I missed something? or would you consider expanding the features of TMPL_IF?

I do it this way:
<select>
<TMPL_LOOP foo>
   <option value=<TMPL_VAR foo>> <TMPL_IF bar>selected</TMPL_IF>>
</TMPL>
</select>

In Perl I have

$dbq = "SELECT foo, (foo = $myfoo) AS bar FROM footable";

...

my @loop;
while ($row=$sth->fetchrow_hashref)
{
  push @loop, $row;
}

Why not simply append text to the variable you wish to put in the option-tag:

<select>
<TMPL_LOOP>
<option value=<TMPL_VAR userid>><TMPL_VAR username>
</TMPL>
</select>

and in perl:

foreach(resultset foo)
{
$userid .= " selected " if ($selected);
$loopvalues{userid} = $userid;
$loopvalues{username} = $name;
}

...but then again, avoiding unnecessary assignments (i.e. using _arrayref directly) is better for performance.
