HTML::FormFu::Constraint::File - File Upload Constraint
version 2.09
Ensure the submitted value is a file upload.
This Constraint is not needed if you use any of the File::* Constraints,
as they all make the same check as this Constraint does.
This can only verify that your CGI backend (CGI,
Catalyst,
CGI::Simple) thinks it was a file upload.
If the user submits a filename which doesn't exist on their system,
you will probably get a valid HTML::FormFu::Upload object,
with a valid filehandle,
but no Content-Length.
This Constraint would still see this as a valid uploaded file - if you want to ensure that you get a file with content,
instead use HTML::FormFu::Constraint::File::Size with min set to 1.
Is a sub-class of, and inherits methods from HTML::FormFu::Constraint
