Description:
module to process CGI input parameters
Dealing with large web based applications with multiple forms is a minefield. It's often hard enough to ensure you validate all your input at all, without having to worry about doing it in a consistent manner. If any of the validation rules change, you often have to alter them in many different places. And, if you want to operate taint-safe, then you're just adding even more headaches. . CGI::Untaint provides a simple, convenient, abstracted and extensible manner for validating and untainting the input from web forms. . You simply create a handler with a hash of your parameters (usually $q->Vars), and then iterate over the fields you wish to extract, performing whatever validations you choose. The resulting variable is guaranteed not only to be valid, but also untainted.
