Hi,

I'm using Perl 5.10.1. I'm trying to fill in an HTML::Template, which
consists of

<TMPL_LOOP NAME=TESTS>
<tr><td><a href="<TMPL_VAR NAME=ABSOLUTE_PATH>"><TMPL_VAR
NAME=FILE_SHORT_NAME></a></td></tr>
</TMPL_LOOP>


but I'm getting an error when I try and do the following ...

my @loop_arr;
foreach (@test_files) {
my $test_file = $_;
my %params_hash;
$params_hash{'absolute_path'} = $test_file;
$params_hash{'file_short_name'} = $test_file;
push(@loop_arr, %params_hash);
}
# open the html template
my $template = HTML::Template->new(filename => '/opt/scripts/selenium/
report_suite.templ');
$template->param(TESTS => @loop_arr);

The error is complaining about the last line. I tried changing
"@loop_arr" to "$loop_arr" but that gave some undefined variable
errors. Could someone point out the error(s) of my ways?

Thanks, - Dave

$template->process(TESTS => \@loop_arr);

Give the documentation a try.

maybe => [@loop_arr]

since => imply's a hash element, which can't be an array,
but can be a reference to an array.

In which case you might want to use => \@loop_arr instead. Correct me if
I am wrong but you're now copying @loop_arr into an empty hash you
created a reference too. Sometimes that's what you want (for example if
you want to keep a copy), but in this case most likely not.

It was hard to tell what he wanted to do. Looked like he wanted to copy
the array to this place, therefore the new array. Otherwise, it appears
if he doesen't know what [] is, he isin't going to know what \@ar is.
I stopped guessing what's in the minds of people.

Thanks Tad, indeed that should have read array
