This should be stunningly easy, but for some reason the 'keys' VMethod
is giving me nothing.
My template:
---
should tell me this is a hash:
[% cgihash %]
dump out the contents of the hash:
[% USE Dumper %]
[% Dumper.dump(cgihash) %]
Now give me the keys:
[% cgihash.keys %]
[[ TEMPLATE ENDS ]]
Apparently not! Still gives me nothing...
It's like the keys vmethod is being completely ignored.

Might [% cgihash.keys.join("\n") %] help here?

I guess my example wasn't a very good one - I just wanted to demonstrate
that I was getting _nothing_ when using the keys method. If it had
worked as expected, then it should have returned something like
'ARRAY(0x8a8ca58)'
I keep playing, and so far any vmethods I use on the hash don't seem to
Hi,
this may help you:
[% FOR entry IN cgihash %]
key is: [% entry.key %]
value is: [% entry.value %]
[% END %]
Greets,

Right! So - there's something REALLY weird going on here...
To answer Simon, cgihash is from perl's CGI lib: my $cgi = new CGI; my
$cgihash = $cgi->Vars;
Shouldn't be anything odd about it. But obviously it's behaving
differently for some reason.
New example. cgihash continues to act as before

Hmm, weird.
On my machine
% cat foo.tt
[%- cgihash = { 'a' => 1, 'b' => 2, 'c' => 3 } -%]
[% cgihash.keys.join("\n") %]
% tpage foo.t

Ouch. So there *is* indeed something special about $cgihash: It is
a tied hash, tied to the CGI
Terrific! That did the job.
I've used $cgi->Vars for ages and never had this trouble before. Guess
I'd never tried to do this before.
Thanks everyone for all your help.

action at a distance. nasty...

No wonder I came a cropper!
I'd kinda ignored the CGI aspect, as usually if you've got something
more than just a plain and simple data structure it shows up as such in
Data::Dumper. Since it looked like a plain old hash, I treated it as a
plain old hash.
Thanks again, everyone!

Maybe, rather than rolling your own hookup to CGI, you should look at
the CGI plugin for TT:
http://template-toolkit.org/docs/modules/Template/Plugin/CGI.html
It has code to avoid the exact issue you ran into. One extra method that
does what you need.
