Searching CPAN
So we have all this parameter checking. Wouldn't it be nice to have a module to do it for us. Afterall, as a rule modules on CPAN generally well supported.
We do a search on http://search.cpan.org for 'cgi params'. Strangely the first module to pop up that looks like fitting the bill is:
|
Params::Check |
After some further investigation we can discover:
|
Params::Validate Data::FormValidator |
Params::Check and Params::Validation are very close, but Data::FormValidation does some very different validation.
