Symfony2 standalone form component - setting up a form

Question

I'm trying to implement Symfony2 form builder component as a standalone. The documentation doesn't really talk about this though, just in relation to using the whole framework.

The standalone is on Github but has no docs.

Ive searched around and seen a few people ask this question but none seems to have any answers.

All I need is a basic guide on how to setup a form , build it, then view it.

Anyone?

Previous (now obsolete) answer:

I've tried hard and managed to display a form (using PHP engine, not Twig).

Indeed you need a few components: Form, but also ClassLoader, EventDispatcher, Templating (for rendering) and Translation (for rendering labels). You will also need some resources from the FrameworkBundle bundle (mainly templates).

Answer 2

First, copy Form Component to your project to directory which contains third-party libraries (not only Symfony components, but also ORM or whatever), let's say lib/, so it's in <project_path>/lib/Symfony/Component/Forms.

Then you have to auoload it - either manually or using any PSR-0 compatible class loader i.e. SplClassLoader or Symfony's UniversalClassLoader (there is chapter in docs and in quick tour about this). Example:

$loader = new UniversalClassLoader();
$loader->registerNamespace('Symfony', __DIR__.'/lib');
$loader->register();

Using Form Component isn't in fact strongly documented, but in Symfony Book there are few examples how to use Form classes about this component, so I guess you'll have to dive into sources, beginning with Form class (maybe later you'll give some feedback about experiences somewhere in the Web?).

Answer 3

Since Symfony 2.1, the form component has been using composer.

You can locate the composer.json file inside the repository. It contains a dependency map that can be used to get the dependencies installed.

You can do so by simply running composer install from inside your console.
