sfForms11Plugin: use symfony 1.1 form/validation framework in symfony 1.0 or non-symfony project

The new symfony 1.1 form/validation framework is 100% symfony-independant, and though is not limited to the (very) awaited 1.1 stable release. To use it in your own symfony 1.0 projects, you can use sfForms11Plugin. It's content is very thin: it only sets up externals to symfony 1.1 form/widget/validator libraries.

To use it, simply add the following external to your project:

sfForms11Plugin http://svn.symfony-project.com/plugins/sfForms11Plugin

Or check it out from your project base directory:

svn co http://svn.symfony-project.com/plugins/sfForms11Plugin plugins/sfForms11Plugin

Let's try it...

Now you'll be able to define sfForm sub-classes to materialize forms:

class HelloWorldForm extends sfForm

{

  public function configure()

  {

  }



  public function setup()

  {

    $this->setWidgetSchema(new sfWidgetFormSchema(array(

            'name' => new sfWidgetFormInput(),

            )));



    $this->setValidatorSchema(new sfValidatorSchema(array(

            'name' => new sfValidatorString(array('required'=>true, 'min_length'=>1, 'max_length'=>50)),

            )));



    $this->widgetSchema->setNameFormat('hello[%s]');

    $this->errorSchema = new sfValidatorErrorSchema($this->validatorSchema);



    parent::setup();

  }

}

This class define the model of your HelloWorldForm, and you can now use it in your actions:

class testActions extends sfActions

{

  function executeHelloWorld()

  {

    $this->form = new HelloWorldForm();



    if ($this->getRequest()->getMethod() == sfRequest::POST)

    {

      if (null !== ($hello = $this->getRequestParameter('hello', null)))

      {

        $this->form->bind($hello);



        if ($this->form->isValid())

        {

          $this->redirect('@hello?name='.$this->form->getValue('name'));

        }

      }

    }

  }

}

At this point, the only little detail still missing is the view, containing actual form display:

<form method="POST">

<table>

<?php echo $form; ?>

<tr>

  <td colspan="2" align="right">

    <input type="submit" value="Greetings, Mr Computer!" />

  </td>

</tr>

</table>

</form>

That's it! You now have a simple form, self-validating, protected against CSRF attacks and redirecting to some place if values entered matched our sfValidatorSchema.
