HTML::FormHandler::TraitFor::Captcha - generate and validate captchas

version 0.40068

A role to use in a form to implement a captcha field.
   package MyApp::Form;
   use HTML::FormHandler::Moose;
   with 'HTML::FormHandler::TraitFor::Captcha';
or
   my $form = MyApp::Form->new( traits => ['HTML::FormHandler::TraitFor::Captcha'],
       ctx => $c );
Needs a context object set in the form's 'ctx' attribute which has a session hashref in which to store a 'captcha' hashref, such as is provided by Catalyst session plugin.

Get a captcha stored in "$form->ctx->{session}"

Set a captcha in "$self->ctx->{session}"

Default is '/captcha/image'. Override in a form to change.
   sub captcha_image_url { '/my/image/url/' }
Example of a Catalyst action to handle the image:
    sub image : Local {
        my ( $self, $c ) = @_;
        my $captcha = $c->session->{captcha};
        $c->response->body($captcha->{image});
        $c->response->content_type('image/'. $captcha->{type});
        $c->res->headers->expires( time() );
        $c->res->headers->header( 'Last-Modified' => HTTP::Date::time2str );
        $c->res->headers->header( 'Pragma'        => 'no-cache' );
        $c->res->headers->header( 'Cache-Control' => 'no-cache' );
    }
