.SH "NAME"
HTML::FormFu::Constraint::File \- File Upload Constraint
.SH "VERSION"
.IX Header "VERSION"
version 2.07
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Ensure the submitted value is a file upload.
.PP
This Constraint is not needed if you use any of the \f(CW\*(C`File::*\*(C'\fR Constraints,
as they all make the same check as this Constraint does.
.SH "LIMITATIONS"
.IX Header "LIMITATIONS"
This can only verify that your \s-1CGI\s0 backend (\s-1CGI,\s0 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 \f(CW1\fR.
