Annoying PERL Problem

Gareth37

Hi,

Im generating a PDF report using PERL but am having problems with a simplish problem Im thinking.

When I manually code $records a sfollows it generates the PDF report no problem:

$records = [

[$ww[0], $ww[3], $ww[1], $ww[4],$ww[2],"Score: fd[0]. Last goal on $fd[3]. Scorer is $fd[0]."],

];

$data->{data_array} = @records;
$report->render_data($data);
$report->save;

However, I would like to generate each line of the matrix dynamically. For example if there are 3 goals this is what I should write in records:

$records = [

[$ww[0], $ww[3], $ww[1], $ww[4],$ww[2],"Score: fd[0]. Last goal on $fd[3]. Scorer is $fd[0]."],


[$ww2[0], $ww2[3], $ww2[1], $ww2[4],$ww2[2],"Score: fd2[0]. Last goal on $fd2[3]. Scorer is $fd2[0]."],


[$ww2[0], $ww2[3], $ww2[1], $ww2[4],$ww2[2],"Score: fd2[0]. Last goal on $fd2[3]. Scorer is $fd2[0]."]

];

Does anyone know how I can dynamically create the Matrix? Ive tried using a for loop but it didnt work out for me. Help!!!

This is a job for my favourite section of the perl docs - perldsc, the Data Structures Cookbook. Look at the Generation of an ARRAY of Arrays section.

The Data::Dumper module can be helpful to confirm that your data structure looks how it should.

/edit I'm stupid... should have read the problem

Well I didnt need the fancy modules but i got it working. It was trivial in the end. Thanks for the link. Here is 1 solution:

$records->[19][0] = "One";
$records->[19][1] = "Two";
$records->[19][2] = "etc";

I can access the array dynamically using a for loop now using the above simple array access methods. I need to learn more thats all.
