I'm pretty new to symfony and symfony forms.
I have a form with an EntityType, that looks like this:
->add('customer', EntityType::class, [
'label' => 'Kunde: ',
'class' => Customer::class,
'choice_label' => 'Name',
'query_builder' => function(EntityRepository $er) {
return $er->createQueryBuilder('c')
->select('CONCAT(c.firstname, " ", c.surname) AS Name');
}
])
But I now get an Error/Warning:
Warning: spl_object_hash() expects parameter 1 to be object, string given
Customer Entity:
/**
* @ORM\Entity(repositoryClass="App\Repository\CustomerRepository")
*/
class Customer
{
/**
* @ORM\Id
* @ORM\GeneratedValue
* @ORM\Column(type="integer")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="firstname", type="string", length=50, nullable=false)
*/
private $firstname;
/**
* @var string
*
* @ORM\Column(name="surname", type="string", length=50, nullable=false)
*/
private $surname;
...
Thank you very much for your time and help.
You could also simply use a callback for the choice_label
E.g.:
->add('customer', EntityType::class, [
'label' => 'Kunde: ',
'class' => Customer::class,
'choice_label' => function (Customer $customer) {
return $customer->getFirstname() . ' ' . $customer->getSurname();
// or better, move this logic to Customer, and return:
// return $customer->getFullname();
},
])
Not sure if this works with Symfony 4 but it does work with symfony 5. This is more of an extension of Yoshis' answer than a new answer.
If you create a getFullname()
function as suggested by Yoshi you can do the following.
Customer.php:
public function getFullname(): ?string {
return $this->firstname . ' ' . $this->surname;
}
Then in your form:
->add('customer', EntityType::class, [
'label' => 'Kunde: ',
'class' => Customer::class,
'choice_label' => 'fullname'
])
Adding the fullname function to the customer also allows you to use fullname within your twig files.
eg.
{{ customer.fullname }}
Have you created a __toString()
method in your customer entity.
/**
* toString
*
* @return string
*/
public function __toString() {
return $this->getFirstname().' '.$this->getSurname();
}
Then, something like this should be enough :
->add('customer')
If customer is related to your entityType, this should be enough
