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?
