Re: Passing hash references

[fauria]

In general, i access hashrefs values which i dont know their structure by looking at Data::Dumper output, and then:

$hashref->{brackets_1}->{brackets_n}{quotes}

Regarding books, i really like Perl Cookbook, chapter 5 covers this topic.

Also, ive found Merlyn's article List Manipulation, very useful. It was published in April 2004 Linux Magazine issue.

Finaly, you can take a look at Steve's place lesson 7. It is really good.

my $names = &getNames; my $valid_names = &validateNames(\$names); usually, I noticed that &validateNames(\$names); could be &validateNames($names); just to make things easier. However, you can use it, just more messy looking

sub validateNames{ 
  my $valid_names=shift; 
  print Dumper($valid_names); 
  # I want to access ( print ) the data here
   
  my $category = ();
  foreach $category (sort keys %{${$valid_names}})
  {
     print "INFO - $category . Name : " . ${${$valid_names}}{$category
+}{'name'} . "\n";
     print "INFO - $category .  Email : " . ${${$valid_names}}{$catego
+ry}{'email'} . "\n";     
  }
}
