I did not see anything regarding retiaining selections in select boxes
in that discussion Kieren. Can someone post a link?
I have the same problem as you Kim. I just wrot a macro to
"set_selected" element to value. Here it is;
[%#
=head2 set_selected
Set which option in the select box element is selected based on value.
"element" is an HTML::Element object of type select.
=cut
%]
[% MACRO set_selected(element, value) BLOCK;
FOR opt IN element.content_list;
IF opt.attr('value') != value;
opt.attr('selected', undef);
ELSIF opt.attr('value') == value;;
opt.attr('selected', 'selected');
LAST;
END;
END;
END;
%]
I call this in search template *After* I put an empty option on the
top. HEre is snip from that.
[% SET element = classmetadata.cgi.$field; %]
<div class="row">
<span class="label">[% "$name_prefix " IF name_prefix;
classmetadata.colnames.$field || field FILTER ucfirst; %]</span>
[% IF element.tag == "select";
# unset selected element
#FOR opt IN element.content_list;
# opt.attr('selected', undef) IF opt.attr('selected');
#END;
# put empty opt as top if we don't have one
IF (element.content_list.0.content_list) ;
USE element_maker = Class("HTML::Element");
SET element = element.unshift_content(
element_maker.new("option", 'value', ""));
END;
# set the previous value
IF cgi_params.exists(field);
set_selected(element, cgi_params.$field);
END;
END;
%]
Let me know if you have questions.
