i'm coding under mod_perl2 / libaprq, but that shouldn't matter too much...

I often pull post info from a form as such: 
$this->{'ApacheRequest'}->param( "checkbox_field");

[download]
unfortunately, that tends to return a scalar if there is 1 checkbox_field item, or an array if there are more.

I want to standardize info to act as an array, even its its a scalar (ie, create a 1 item list) 
my @tmp = $this->{'ApacheRequest'}->param( "checkbox_field");

I discovered 'wantarray', but i know that i'm using it wrong 
my @tmp = wantarray : $this->{'ApacheRequest'}->param( "checkbox_field
+") : @{$this->{'ApacheRequest'}->param( "checkbox_field")};

[download]
Can someone enlighten me please?
