Well this should be one of the last posts about branch 1.x of symfony. The 2nd version should come to alpha soon so there is no real need to go further with it. Anyway … some time ago I desperately needed a quick and reliable way to embed multiple symfony forms on one page and submit them at once. I generally take the time to look into the source files, but this time i was in a hurry. So this is the “hacky” way i got around:

function executeMoo(sfWebRequest $request) {
$this->forms = array();

$it = 0;

foreach($some_model as $s) {

$f = new MooForm($s);

$f->getWidgetSchema()->setNameFormat('foo[' . $form->getName() . $it . '][%s]');

$this->form->embedForm($it, $form);
$this->forms[] = $this->form;
$it++;

}
}

The presentation part should be as simple as:

<form ...>
<table>
<tr>
<td><table>
<?php
foreach($forms as $form) :
   echo $form;
endforeach;
?>
</table></td>
</tr>
</table>
</form>
</pre>

Ok now for the validation part:

public function executeSubmit_Foo(sfWebRequest $request) {
         $this->forward404Unless($request->isMethod(sfRequest::POST));

   	$base_forms = $request->getParameter('foo');

	foreach($base_forms as $base_form) {
		$f = new MooForm();
		$f->bind($base_form,null);
		if($f->isValid()) {
			$f->save();
		}
	}
}

What’s the catch?
Well the catch is in this line: $f->getWidgetSchema()->setNameFormat(‘foo[' . $form->getName() . $it . '][%s]‘);
What it really does? it generates the form fields like foo['forms_name1'] … so the only thing you have to do is grabbing the foo var from request and looping through to get the embedded forms.
Sure there are better ways, but this worked nice with a minimum ammount of time spent.
Hope it helps.
