5

Hi
I have a variable which should be any number between 1 and 50.
It could also be any string/empty string.
I have a code written below. The point is when the variable contains string.
I don't want the code below to error out. Instead fall in the else bucket.

params::validate::dummy
Params::Validate::Dummy(3pm) User Contributed Perl Documentation Params::Validate::Dummy(3pm)NAME
Params::Validate::Dummy - Stub for Params::Validate
SYNOPSIS
use Params::Validate::Dummy qw();
use Module::Optional qw(Params::Validate);
DESCRIPTION
This module provides stub routines for those who don't have Params::Validate installed.
For more details, please refer to the documentation for Params::Validate.
The code here is just stub routines which do NOTHING at all, passing through any arguments in the API and prototypes of Params::Validate.
In particular, the dummy stubs do not do defaulting, validation, untainting or anything else that Params::Validate does. If you need this
functionality, either provide it yourself in the surrounding code, or don't use this module and insist that the real Params::Validate is
installed.
"validate", "validate_pos"
The parameter list is passed through as a return value.
"validate_with"
Returns the value of the params option.
"set_options", "validation_options"
These do nothing at all.
Data types: "SCALAR", "SCALARREF", "ARRAYREF", "HASHREF", "GLOB", "GLOBREF", "BOOLEAN", "CODEREF", "HANDLE", "OBJECT", "UNDEF", "UNKNOWN"
In the Params::Validate module, these are constants implemented by subs that return numbers. This module implements the same functions.
SUPPORT
See Module::Optional
