Re: Handling multiple file upload with Mojo

Just to make this code complete with working example. Did not know this, but Mojolicious has no dependencies, and also CGI is out of Perl core.

#!/usr/bin/env perl
use strict;
use warnings;
use Mojolicious::Lite;

my $uploadFileDirectory = 'UPLOADS';
mkdir $uploadFileDirectory if ( !-d $uploadFileDirectory );

$ENV{"MOJO_MAX_MESSAGE_SIZE"} = 25 * 2**20;    #25 MB

get '/upload' => sub {
    my $c = shift;
    $c->render('simpleUploadForm');
};

post '/handleUpload' => sub {
    my $c = shift;
    my @fileNames;
    my $files = $c->req->every_upload('files');
    for my $file ( @{$files} ) {
        my $fileName = $file->filename =~ s/[^\w\d\.]+/_/gr;
        $file->move_to("$uploadFileDirectory/$fileName");
        $c->app->log->debug("$fileName uploaded\n");
        push @fileNames, $fileName;
    }
    $c->render( 'successUpload', files => \@fileNames );
};

app->start;

Update: Must use method "every_upload" introduced in Mojolicious 5.48 or you will only get one file.
