Hello Monks,

I get values from front end in a hash. What I want to do is create variables (array or scalar) only for those hash keys that are not empty.

Also these array or scalar variables generated should NOT have scope limited to a loop. They should be available anywhere in program.

Is it possible to do it?

What I am doing right now is creating fixed number of variables for all the known keys. But the number of keys sent by front end might change and I won't be able to handle that. I want to be able to create variables by checking the keys and their values.

#!/opt/apps/perl/perl5261/bin/perl
 
 use strict;
 use warnings;

 my %params = {
    'default-0' => ['lakja', 'haljl', 'alka'],
    'default-1' => 'abc',
    'default-2' => [1, 54, 83, 23],
    'default-3' => [],
    'default-4' => '',
    'default-5' => '2019-06-26 00:00:10',    
};

my @arr_0 = @{ $passedParameters{'default-0'} } 
    if defined($passedParameters{'default-0'});
my $scal_1 = $passedParameters{'default-1'} 
    if defined($passedParameters{'default-1'});
my @arr_2 = @{ $passedParameters{'default-2'} } 
    if defined($passedParameters{'default-2'});
my @arr_3 = @{ $passedParameters{'default-3'} } 
    if defined($passedParameters{'default-3'});    
my $scal_4 = $passedParameters{'default-4'} 
    if defined($passedParameters{'default-4'});
my $date_5 = $passedParameters{'default-5'} 
    if defined( $passedParameters{'default-5'});
