Continuing on my journey of struggles w/ doing a little more complicated HTML::Template work, I find myself with this problem...

I have a page that displays a table of data. The user is given the option of selecting which columns of data will be displayed.

I'm trying to keep my code as neat as possible. I know I could just have a VAR in the template, and do a ton of if statements in the template file, to see if each column was selected, but I would rather do it as a LOOP. It will save my template file at least 40 lines of code, and keep things a lot neater.

Simple example/explanation:

A table has 5 optional columns via checkboxes. The user checks off the boxes, clicks submit, then the appropriate columns are displayed when the page is generated.

If the user selects columns 2, 4 and 5, the page is generate showing a table with only those 3 columns.

Earlier in the file, I store the selections in an array.
So...
my @selections = (2, 4, 5);

Column names:
1 = column number 1
2 = column number 2
3 = column number 3
4 = column number 4
5 = column number 5

could someone suggest some code as how I could create the appropriate variable to send to the HTML Template so that it can loop through them?

ie. how would you store the selected column header's names into $rows, so that the following would work?

my $template=HTML::Template->new(filename=>"tmpl/bottom.tmpl");
$template->param(ROWS => $rows);
print $template->output;


Any help would be GREATLY appreciated!
