Symfony 2 – how to pass data to formBuilder?

by

You can give the object you want to use in the __construct() method.

Eg :

$form = $this
    ->get('form.factory')
    ->create(new ApplyStepOneFormType($this->company, $this->ad), $applicant);

In your form type :

function __construct(\Your\Bundle\Entity\Company $company, \DYB\ConnectBundle\Entity\Ad $ad) {
    $this->company = $company;
    $this->ad = $ad;
}

And then in your form type in buildForm method :

$company = $this->company;    
$builder->add('ad', 'entity', array(
    'class' => '\Your\Bundle\Entity\Ad',
    'query_builder' => function(\Your\Bundle\Repository\AdRepository $er) use ($company) {
        return $er->getActiveAdsQueryBuilder($company);
    },
));
