Question

I am having two entity files one as user.php and another as usertype.php. now i want to display a login form with 3 fields viz username, password and usertype. the usertype will be a selection that will fetch data from usertype table. here is the code that i wrote inside user.php to create a manytoone field for usertype_id

/**
* @ORM\ManyToOne(targetEntity="Usertype")
*/
protected $usertype;

Below is my Form generation Code

class LoginForm extends AbstractType
{
    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder->add('login', 'text', array('label'  => 'Username',));
        $builder->add('password');
    }
}

Now I need to add one more field to my form builder that will be a selection of usertype table.

Answer 1

...
use Acme\YourBundle\Entity\Usertype;

class LoginForm extends AbstractType {

    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder->add('usertype', 'entity',
            array(
                'class' => 'AcmeYourBundle:Usertype'
                'label' => 'User Type',
            )
        );
    }
}

You can read more informations about the entity field type wich will give you the options available for this type of field.

Don’t forget to add a __toString() method to your model to tell the form builder what to display.

namespace Acme\YourBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

class Usertype
{
    public function __toString()
    {
        return $this->getName();
    }
}
