Imagine this scenario: in our company there is an employee that "play" around graphic,css,html and so on.
Our new project will born under symfony2 so we're trying some silly - but "real" - stuff (like authentication
from db, submit data
from a form and persist it to db and so on..)
The problem
As far i know, learnt
from symfony2 "book" that i found on
the site (you can find it here), there is an "automated" way for creating and rendering forms:
1) Build
the form up into a controller in this way
$form = $this->createFormBuilder($task)
->add('task','text'),
->add('dueDate','date'),
->getForm();
return $this->render('pathToBundle:Controller:templateTwig',
array('form'=>$form->createview());
2) Into templateTwig render
the template
{{ form_widget(form) }} // or single rows method
3) Into a controller (the same that have a route where you can submit data), take back submitted information
if($rquest->getMethod()=='POST'){
$form->bindRequest($request);
/* and so on */
}
Return to scenario
Our graphic employee don't want to access controllers, write php and other stuff like those. So he'll write a twig template with a "unconventional" (from symfony2 point of view, but conventional
from HTML point of view) method:
/* into twig template */
<form action="{{ path('SestanteUserBundle_homepage') }}" method="post" name="userForm">
<div>
USERNAME: <input type="text" name="user_name" value="{{ user.username}}"/>
</div>
<div>
EMAIL: <input type="text" name="user_mail" value="{{ user.email }}"/>
</div>
<input type="hidden" name="user_id" value="{{ id }}" />
<input type="submit" value="modifica i dati">
</form>
Now, if into
the controller that handle
the submission of data we do something like that
public function indexAction(Request $request)
{
if($request->getMethod() == 'POST'){ // sono arrivato per via di un submit, quindi devo modificare i dati prima di farli vedere a video
$defaultData = array('message'=>'ho visto questa cosa in esempio, ma non capisco se posso farne a meno');
$form = $this->createFormBuilder($defaultData)
->add('user_name','text')
->add('user_mail','email')
->add('user_id','integer')
->getForm();
$form->bindRequest($request); //bindo la form ad una request
$data = $form->getData(); //mi aspetto un'array chiave=>valore
/* .... */
We expected that $data will contain an array with key,value
from the submitted form.
We found that it isn't true. After googling for a while and try with other "bad" ideas, we're frozen into that.
So, if you have a "graphic office" that can't handle directly php code, how can we interface
from form(s) to controller(s) ?
UPDATE
It seems that Symfony2 use a different convention for form's
field name and lookup once you've submitted that.
In particular, if my form's name is addUser and a
field is named userName,
the field's name will be AddUser[username] so maybe it have a "dynamic" lookup method that will extract form's name,
field's name, concat them and lookup for values.
Is it possible?
