CGI::Expand 2.02

CGI::Expand is a Perl module that can convert flat hash to nested data using TT2s dot convention.

SYNOPSIS

use CGI::Expand;
use CGI; # or Apache::Request, etc.

$args = expand_cgi( CGI->new(a.0=3&a.2=4&b.c.0=x) );
# $args = { a => [3,undef,4], b => { c => [x] }, }

# Or to catch exceptions:
eval {
$args = expand_cgi( CGI->new(a.0=3&a.2=4&b.c.0=x) );
} or log_and_exit( $@ );

#-----
use CGI::Expand qw(expand_hash);

$args = expand_hash({a.0=>77}); # $args = { a => [ 77 ] }

Converts a CGI query into structured data using a dotted name convention similar to TT2.

expand_cgi works with CGI.pm, Apache::Request or anything with an appropriate "param" method. Or you can use expand_hash directly.

If you prefer to use a different flattening convention then CGI::Expand can be subclassed.
