I'll throw my technique into the ring, too. I use Template Toolkit
most of the time, and I pass the original Apache request object back
to the template as a parameter. Then I call the "param" method to
fill in the "value" of form elements, like so:
In code:
sub handler {
my $r = shift;
my $apr = Apache::Request->new($r);
my $t = Template->new;
my $html;
$t->process('/foo/bar.tmpl', { apr => $apr }, \$html);
$apr->content_type('text/html');
$apr->send_http_header;
$apr->print( $html );
return OK;
}
In template:
<form>
<input name="foo" value="[% apr.param('foo') %]">
<textarea name="text">[% apr.param('description') %]</textarea>
</form>
Nothing gets placed there the first time through as calling
"$apr->param" returns nothing. This seems to work great for me. I've
not used HTML::Template in a while, but possibly you can do this, too?
Template Toolkit makes it easy to call methods (or deference hashes
and hash references) with the "dot" notation.
