Hey folks. I have been trying to figure out how one might do this. It seems
like it ought to be simple.
I have a select menu initially generated in my init block. Pretty
straightforward. Here's the HTML.
Select an object<br />
<select name="object_id" value="<% $ARGS{'object_id'} %>"
onchange="visibility('subobject');">
<option value=""></option>
% foreach my $object (@$objects) {
<option value="<% $object->[0] %>"><% $object->[8] %></option>
% }
</select>
So, the part that gets hairy is the subobject. I need somehow to grab the
selected value above and use it to limit the database query that generates
the next menu. As is, my subobject select is just another full-fledged
database query that gets all subobjects, not those tied ot the object. It
looks exactly like the above.
<div style="display:none" id="subobject">
Select a subobject<br />
<select name="subobject" value="<% $ARGS{'subobject'} %>"
onchange="visibility('subsub');">
<option value=""></option>
% foreach my $subobject (@$subobjects) {
<option value="<% $subobject->[0] %>"><% $subobject->[3] %> by
<% $subobject->[5] %></option>
% }
</select>
There must be some bit of Perlish thinking that is escaping me. Some bit of
magic I don't know. Here's hoping!
Amiri
