-Catalyst::Request::Upload - Catalyst Request Upload Class
+Catalyst::Request::Upload - handles file upload requests
=head1 SYNOPSIS
- $upload->fh
+ $upload->basename;
+ $upload->copy_to;
+ $upload->fh;
$upload->filename;
- $upload->link;
+ $upload->headers;
+ $upload->link_to;
$upload->size;
+ $upload->slurp;
$upload->tempname;
$upload->type;
+To specify where Catalyst should put the temporary files, set the 'uploadtmp'
+option in the Catalyst config. If unset, Catalyst will use the system temp dir.
+
+ __PACKAGE__->config( uploadtmp => '/path/to/tmpdir' );

=head1 DESCRIPTION
-This is the Catalyst Request Upload class, which provides a set of accessors to the
-upload data.
+This class provides accessors and methods to handle client upload requests.
=head1 METHODS
-=over 4
+=head2 $upload->new
-=item $upload->fh
+Simple constructor.
-Opens tempname and returns a C<IO::File> handle.
+=head2 $upload->copy_to
+
+Copies the temporary file using L<File::Copy>. Returns true for success,
+false for failure.
+
+ $upload->copy_to('/path/to/target');

-sub fh {
+sub copy_to {
my $self = shift;
+ return File::Copy::copy( $self->tempname, @_ );
+}
- my $fh = IO::File->new( $self->tempname, O_RDWR )
- or die( "Can't open ", $self->tempname, ": ", $! );
+=head2 $upload->fh
- return $fh;
-}
+Opens a temporary file (see tempname below) and returns an L<IO::File> handle.
+
+=head2 $upload->filename
+
+Returns the client-supplied filename.
+
+=head2 $upload->headers
+
+Returns an L<HTTP::Headers> object for the request.
+
+=head2 $upload->link_to
-=item $upload->filename
+Creates a hard link to the temporary file. Returns true for success,
+false for failure.
-Contains client supplied filename.
+ $upload->link_to('/path/to/target');
-=item $upload->link
+=cut
+
+sub link_to {
+ my ( $self, $target ) = @_;
+ return CORE::link( $self->tempname, $target );
+}
+
+=head2 $upload->size
-Creates a new filename linked to the old filename. Returns true for
-success, false otherwise.
+Returns the size of the uploaded file in bytes.
- $upload->link('/my/path');
+=head2 $upload->slurp
+
+Returns a scalar containing the contents of the temporary file.

-Contains size of the file in bytes.
+=head2 $upload->basename
-=item $upload->tempname
+Returns basename for C<filename>.
-Contains path to the temporary spool file.
+=head2 $upload->tempname
-=item $upload->type
+Returns the path to the temporary file.
-Contains client supplied Content-Type.
+=head2 $upload->type
-=back
+Returns the client-supplied Content-Type.
