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 \f(CW1\fR. .SH "SEE ALSO" .IX Header "SEE ALSO" Is a sub-class of, and inherits methods from HTML::FormFu::Constraint .PP HTML::FormFu .SH "AUTHOR" .IX Header "AUTHOR" Carl Franks, \f(CW\*(C`cfranks@cpan.org\*(C'\fR .SH "LICENSE" .IX Header "LICENSE" This library is free software, you can redistribute it and/or modify it under the same terms as Perl itself. .SH "AUTHOR" .IX Header "AUTHOR" Carl Franks .SH "COPYRIGHT AND LICENSE" .IX Header "COPYRIGHT AND LICENSE" This software is copyright (c) 2018 by Carl Franks. .PP This is free software; you can redistribute it and/or modify it under the same terms as the Perl 5 programming language system itself.
