We could simplify the form request handling by

• supporting a "method" option
• supporting a "request" option that binds the request if its method matches "method"
• supporting an "action" option and helpers for opening and closing tags

We previously had this idea and dropped it. I was inspired again by Zend Framework 2's API and thought that it might be a good idea. Kudos to them.

Proposed simplification (fully BC):

<?php
// in the controller
$form = $this->createForm('my_form', null, array(
    'action' => $this->generateUrl('process_form'),
    'method' => 'POST',
    'request' => $request,
));

// Alternative 1: short
if ($form->isValid()) {
    // process form
}

// Alternative 2: self-describing
if ($form->isBound() && $form->isValid()) {
    // process form
}

Note that the check for $request->getMethod() is not necessary anymore in the above snippet. Also, bind($request) is done implicitely by passing the "request" option (explicit binding is also possible, of course).

{# in the template #}
{{ form_start(form) }}
    {{ form_widget(form) }}
    <input type="submit" />
{{ form_end(form) }}

{# alternative with explicit method or action #}
{{ form_start(form, { method: "GET" }) }}

Thoughts? Preferences for Alternative 1 or 2?
