I don't believe you need the conditional. You can let "my_input_box_value"
evaluate always. If it contains nothing, it will evaluate to nothing. Your
template won't be as cluttered.

This was the thing that was the most difficult for me. I thought H::T should
have a mechanism to handle this more directly. What I do is loop selecting my
values from a database into a hash (using DBI "fetch").
=======================================
while ($sth_select_some_list->fetch) {
# %db_vals is automatically populated because the prepared statement
# has "bind_col" each column to a $db_vals{key}.
if ($db_vals{code} eq $selected_value) {
$sel = ' selected="selected"';
}
else {
$sel = '';
}
push @loop_data, {
VAL => $db_vals{code},
TEXT => $db_vals{display},
SELECTED => $sel,
LANG => ' lang="en"'
}
} # end loop
$template->param(MY_LOOP => [EMAIL PROTECTED]);
==================================
And then the template looks like this:
==================================
<select id="my_list" name="my_list">
<TMPL_LOOP NAME=MY_LOOP><option value="<TMPL_VAR NAME=VAL>"<TMPL_VAR
NAME=SELECTED>><TMPL_VAR NAME=TEXT></option></TMPL_LOOP>
</select>
==================================
A few months ago someone posted a nifty SQL select that created the array to be
passed to the template (all in one SQL).
I actually do a one-time select into a hash, and regenerate the select list
with each display. I do this because I translate the values selected from a
table into whatever language the visitor chose. I don't want to do that with
each display. So, I select and translate when I detect the first time the page
will be displayed in that language. I generate the select list from a those
values which I keep in memory as long as my script is in memory.
This gets back to how I wish there was a way to perform evaluation upon the
cached H::T template. I could evaluate the select list values with the
language. And then only evaluate the "selected" attribute for each display.
