A simple question:
I have one form, it returns one number and I need create this number of labels in Controller.
I try:
$form2 = $this->createFormBuilder();
for($i = 0; $i < $num; $i++) {
$name = 'column'.$i;
$form2->add($name,'number');
}
$form2->getForm();
I think it should very simple, but i can't..
Yes, you can do it with an array / hash map instead of a real object.
Here is an example :
// Create the array
$dataObj = array();
$dataObj['data1'] = '';
$dataObj['data2'] = 'default';
// ... do a loop here
$dataObj['data6'] = 'Hello';
// Create the form
$formBuilder = $this->createFormBuilder($dataObj);
foreach($dataObj as $key => $val)
{
$fieldType = 'text'; // Here, everything is a text, but you can change it based on $key, or something else
$formBuilder->add($key, $fieldType);
}
$form = $formBuilder->getForm();
// Process the form
$request = $this->get('request');
if($request->getMethod() == 'POST')
{
$form->bind($request); // For symfony 2.1.x
// $form->bind($this->get('request')->request->get('form')); // For symfony 2.0.x
if($form->isValid())
{
$dataObj = $form->getData();
foreach($dataObj as $key => $val)
{
echo $key . ' = ' . $val . '<br />';
}
exit('Done');
}
}
// Render
return $this->render('Aaa:Bbb:ccc.html.twig', array(
'requestForm' => $form->createView()));
