Symfony 2 - Contact form and validation - oop

Question

I'm having trouble with contact form on Symfony 2.
Simple form
<form id="contact-form" method="post" action="">
<label for="name">Name: </label>
<input type="text" name="name" id="name" class="input" />
<label for="subject">Subject: </label>
<input type="text" name="subject" id="subject" class="input" />
<label for="text">Text: </label>
<textarea name="text" id="text" class="input"></textarea>
</form>
I read the documentation about validations and form, but I didn't really understand what it was about.
I have two questions
where should post values go, I'm talking about action attribute in form.
how can I validate this simple contact form.
The best would be if you guys show me here or link to how to validate this simple form.
Thanks

You can set the action to any path in your routing. Example <form action="{{ path(...) }}">. From the path, there will be redirect to your controller. In your controller, you can validate the form. I will give you example.
<form id="contact-form" method="post" action="{{ path('form_contact') }}">
<label for="name">Name: </label>
<input type="text" name="name" id="name" class="input" />
<label for="subject">Subject: </label>
<input type="text" name="subject" id="subject" class="input" />
<label for="text">Text: </label>
<textarea name="text" id="text" class="input"></textarea>
</form>
From here, this form will go through routing
// in your routing.yml
form_contact:
pattern: contact
defaults:
_controller: YourNewBundle:Test:contact
Now, let's go to controller part
// TestController.php
public function contact(){
$request = $this->getRequest();
if ($request->query->has('name') || $request->query->has('subject') || $request->query->has('text')){
...
}
}
Just customize with your own code.
