NAME ^

Dancer::Plugin::Form - Dancer form handler for Template::Flute template engine

VERSION ^

Version 0.0060

SYNOPSIS ^

Display template with checkout form:

    get '/checkout' => sub {
        my $form;

        $form = form('checkout');
        
        template 'checkout', {form => $form};
    };

Retrieve form input from checkout form:

    post '/checkout' => sub {
        my ($form, $values);

        $form = form('checkout');
        $values = $form->values();
    };

    $form = form('checkout');
    $form->reset;

DESCRIPTION ^

Dancer::Plugin::Form is used for forms with the Dancer::Template::TemplateFlute templating engine.

Form fields, values and errors are stored into and loaded from the session key form.

METHODS ^
