"what is the correct name for the values either side of the '=>' so I can refer to these things correctly in the future?"

key => value

=> isn't an assignment. It's just a fancy comma that happens to quote its left hand side if its a bareword (unquoted string with no spaces).

Thanks!

$tmpl->param($param, "foo $var bar");

Does it nicely.

This works:

use strict;
my %hash;
my $foo='xxx';
my $bar='yyy';

$hash{$foo}='foo-value';
$hash{$bar}='bar-value';

my($k,$v);
while(($k,$v)=each %hash) {
   print("$k => $v\n");
   }

Just call me stupid, but I don't see what the problem is :-).
HTML::Template::param is a subroutine which takes two arguments, a key and a value. Of course you can loop over a hash and change the keys or values as arguments of the param sub.

This has nothing to do with HTML::Template as such, but it works for every sub or command (like print, etc...).

Perhaps post some actual code so I can understand your problem.

I didn't realise HTML::Template::param took two arguments

firstly) because I was not aware of the functionality of '=>' and that it was actually passing two parameters and not one. secondly) because every example I have ever seen that taught me to use it was of the form 'variable => value'.

Simple problem, simple solution - All in a day's learning.

param does not take two arguments. It takes a list of key/value pairs. Read the documentation next time.

$tmp->param( foo => 'bar', baz => 'quux' );

# or

$tmp->param(%pairs);
