<p>for populating <select>'s i use this sub:</p>
<code>
sub selectify {
my $values = shift;
my $labels = shift;
my $selected = shift;
my %selected = map {$_ => 1} @{$selected};
return [map {
{
value => $_,
label => shift @{$labels},
selected => $selected{$_} || "",
}
} @{$values}];
}
</code>
<p>you use it in a script like:</p>
<code>
$template->param(foo_loop => selectify(\@values,\@labels,\@selected));
</code>
<p>and a template file like:</p>
<code>
<select name="foo">
<tmpl_loop name="foo_loop">
<option value="<tmpl_var name="value">"<tmpl_if name="selected"> selected="selected"></tmpl_if>>
<tmpl_var name="label">
</option>
</tmpl_loop>
</select>
</code>
<p>i usually have the stuff inside the <tmpl_loop> factored out into its own file so i can just do a <tmpl_include> anytime i have a select list. ie, this is what i you actually see all through my templates:</p>
<code>
<select name="foo">
<tmpl_loop name="foo_loop">
<tmpl_include name="option.tmpl">
</tmpl_loop>
</select>
</code>
<p><strong>update:</strong> fixed some unescaped entities.</p>
