in reply to Method autovivification with variable values?

Turn attach into a function that stores the data internally and can do the checking.
{ my %store = (); sub attach { my ($type, $value) = @_; if ($value) { $store{$type} = $value}; } else { my $default = "height=19 width=15 src='/images/attach/ +f' border=0"; return $store{$type} if $store{$type}; $default =~ s/UNKNOWN/$type/; return $default; } } } # Now, call attach('file',"height=19 width=15 src='/images/attach/file.gif' border +=0"); attach('URL',"height=19 width=15 src='/images/attach/URL.gif' border=0 +"); # to initialise, and attach($mime_type); # to access
If you want to objectise it, make attach a method of the {image} object.

Or, hide the function part by using Tie::Hash and tweaking the FETCH function to provide a default.

    We ended up changing $configs{images}{attach} to be a directory.
    So it worked like this
    package ...... more code ...... $configs{images}{attach} = "/path/to/image/dir/"; and later, in another module my $img = "$configs{images}{attach}" . "$att->{mime_type}" . ".gif"; <img src=$img>
    Which works, and allows us to pass almost any image type.
    We even made a ".gif" file (a copy of our unknown.gif) to
    handle blank mime types.

    Thanks for all the help everyone.
