Re: Style in CGI Header

[frozenwithjoy]

Disclaimer: I've never used CGI.pm

The snippet 'src' => [ $_css_path, $_css_path2 ] is using an anonymous array, whereas 'src' => @whatever is using a normal array. Perhaps it will work if you use an array reference to an anonymous array like this:

$whatever = [ $_css_path, $_css_path2 ];
-style => { -code => $page_style, src => $whatever }, #....

For the second part of your question, new paths can be pushed with:

push @{ $whatever }, $_css_path3;

Of course, this will need to be done before print start_html();

So then would this work? I'm in a live environment, so I cannot just test it, it may break if I do it live...



my @cssFiles = ();
push(@cssFiles, {'src' => "$_css_path"});
push(@cssFiles, {'src' => "$_css_path2"});
# Then in the start_html() this line:
-style => {-code=> "$page_style", 'src'=>@cssFiles},

is that how it would work? It does not seem so, because the array has src = and then the -style field has 'src' = ...so seems like I have it wrong.

Can you tell me how to do that right?

Thanks,

There are some kinds of changes where you won't know if they work until you try it on a test system... or in this case a live system... this isn't one of them. CGI is (still) in the Perl core, so this one is particularly easy to test locally.

use CGI ':standard';
my @cssFiles = ("src1");
push @cssFiles, "src2";
print start_html(-style=>{-code=>"code",-src=>\@cssFiles});
__END__
...
<link rel="stylesheet" type="text/css" href="src1" />
<link rel="stylesheet" type="text/css" href="src2" />
<style type="text/css">
<!--/* <![CDATA[ */
code

/* ]]> */-->
</style>
...

So that's a yes, frozenwithjoy's suggestion should work, provided you use an array reference (-src=>\@cssFiles, not -src=>@cssFiles).

If you had a test system, even if it's not an exact mirror of the live system but at least can execute your code, may have saved you the ~20 hours wait on a solution...

Changing your code to follow my earlier suggestion would give something like this:

my $cssFiles = [];
push @{$cssFiles}, $_css_path;
push @{$cssFiles}, $_css_path2;
# Then in the start_html() this line:
-style => { -code => $page_style, -src => $cssFiles },

If you wanted to use an array instead of an array ref, you could try this:

my @cssFiles;
push @cssFiles, $_css_path;
push @cssFiles, $_css_path2;
# Then in the start_html() this line:
-style => { -code => $page_style, -src => \@cssFiles },
