Symfony - Several form on the same page -> ID issue

Question

Hi folks.

I have an issue while displaying several forms of the same model on the same page. The problem is that with the NameFormat, the fields have the same ID :

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

Will display

<form class="update_display_form" id="update_display_0" action="/iperf/web/frontend_dev.php/update_display" method="post"> 
  <input type="checkbox" name="display[displayed]" checked="checked" id="display_displayed" />
  <label for="display_displayed">test</label> 
</form> 
<form class="update_display_form" id="update_display_1" action="/iperf/web/frontend_dev.php/update_display" method="post">
  <input type="checkbox" name="display[displayed]" checked="checked" id="display_displayed" />
  <label for="display_displayed">truc</label> 
</form>

And if you click on the second label, it will activate the first checkbox So I thought I could use the object id to make them unique :

$this->widgetSchema->setNameFormat('display'.$this->getObject()->getId().'[%s]');

But then I can not process the request, since I don't know the name of the parameters.

The best option I found was to set an ID :

$this->widgetSchema['displayed']->setAttributes(array("id" => "display".$this->getObject()->getId() ));

but then I totally loose the connections between the label and the checkbox.

The problem would be solved if I could change the "for" attribute of my label. Does somebody know how to do that ? Or any other option ?

Here's an idea... push a variable to the form class from your action for setting a different name format dynamically:

In your action:

$this->form_A = new displayForm(array(),array('form_id' = 'A')); // pass a form id
$this->form_B = new displayForm(array(),array('form_id' = 'B'));
$this->form_C = new displayForm(array(),array('form_id' = 'C'));

In your form class:

$form_id = $this->getOption('form_id'); // get the passed value
$this->widgetSchema->setNameFormat('display'.$form_id.'[%s]'); // stick it into the name

It's ugly but I'm sure you can come up with something cleaner...
