Handle two different forms in a single page - forms

Question

So I want to handle two forms on one single page, and I've got some problems to do it; I've got a module named 'contact', here is the indexSucces.php
<div id="registerForm">
<form action="<?php echo url_for('contact'); ?>" method="post" id="loginForm">
<?php foreach ($loginForm as $widget): ?>
<?php if(!$widget->isHidden()) { ?>
<?php echo $widget->renderRow(); ?>
<?php } else { ?>
<?php echo $widget->render() ?>
<?php } ?>
<?php endforeach; ?>
<br/><input type="submit" id="loginSubmit" class="btn primary" value="<?php echo __('Envoyer'); ?>" />
</form>
</div>
<div id="registerForm">
<form action="<?php echo url_for('contact'); ?>" method="post" id="registerForm">
<?php foreach ($registerForm as $widget): ?>
<?php if(!$widget->isHidden()) { ?>
<?php echo $widget->renderRow(); ?>
<?php } else { ?>
<?php echo $widget->render() ?>
<?php } ?>
<?php endforeach; ?>
<br/><input type="submit" id="registerSubmit" class="btn primary" value="<?php echo __('Envoyer'); ?>" />
</form>
</div>
Is it possible to handle that in a single action page ? I need to know the way on how to it, I'm stuck since yesterday. For exemple, when I want to submit the first form, it wants to submit the second form with.
Someone can provide me an exemple ? I can post my sh** action page if you want to see how I tried to handle that.
Thanks in advance !
EDIT:
I made this code according to your advice :
public function executeIndex(sfWebRequest $request)
{
$this->loginForm = new loginForm();
$this->registerForm = new registerForm();
$this->processForm($request, $this->loginForm, $this->registerForm);
}
public function processForm(sfWebRequest $request, sfForm $loginForm, sfForm $registerForm)
{
if($request->hasParameter('login'))
{
if($request->isMethod('post'))
{
$loginForm->bind($request->getParameter($loginForm->getName()));
if($loginForm->isValid())
{
$this->redirect('payement');
}
}
} elseif ($request->hasParameter('register'))
{
if($request->isMethod('post'))
{
$registerForm->bind($request->getParameter($registerForm->getName()));
if($registerForm->isValid())
{
$this->redirect('payement');
}
}
}
}
The registerForm is submitting correctly, I can see the errors I've made in the form etc, and if it's correct, it is correctly redirected. But when I submit the loginForm, here is the error :
Argument 1 passed to sfForm::bind() must be an array, string given : on this line
$loginForm->bind($request->getParameter($loginForm->getName()));
Why ?

Yes, you can.
Add a name attribute to your buttons (i.e. login and register), and modify your action to:
if ($request->hasParameter("login")) {
// handle login
}
elseif ($request->hasParameter("register")) {
// handle register
}
