Symfony and FormTypes

[jiros1]

Hi!

 

For a form I would like to render a selectbox with values from another relation: Type.

This is a many-to-one relation, owned by Type.

Type has many Games, while Game has one Type

 

My question is, how do I show a selectbox with values from Type?

e.g:

Game: Monopoly

Select Type: (selectbox)

- Party game

- Strategy

- Co-op

- etc.

 

-----------------------------------------------

 

This is what I have:

 

GameType.php

<?php

namespace AppBundle\Form;

use AppBundle\Entity\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class GameType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name');
        $builder
        ->add( 'types', choiceType::class, [
        'class' => 'AppBundle:Type',
        'choice_label' => 'name',
        'multiple' => false,
        'choices_as_values' => true,
        'expanded' => true
    ] );


    }
    
    /**
     * {@inheritdoc}
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'types' =>  [],
            'data_class' => 'AppBundle\Entity\Game'
        ));
    }

    /**
     * {@inheritdoc}
     */
    public function getBlockPrefix()
    {
        return 'appbundle_game';
    }


}

Entity/Game.php

<?php

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;


/**
 * Game
 *
 * @ORM\Table(name="game")
 * @ORM\Entity(repositoryClass="AppBundle\Repository\GameRepository")
 */
class Game
{
    /**
     * @ORM\ManyToOne(targetEntity="Type", inversedBy="games")
     * @ORM\JoinColumn(name="type_id", referencedColumnName="id")
     */
    private $type;



    /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;


    /**
     * @var string
     *
     * @ORM\Column(name="name", type="string", length=255, unique=true)
     */
    private $name;


    /**
     * Get id
     *
     * @return int
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set name
     *
     * @param string $name
     *
     * @return Game
     */
    public function setName($name)
    {
        $this->name = $name;

        return $this;
    }

    /**
     * Get name
     *
     * @return string
     */
    public function getName()
    {
        return $this->name;
    }

    /**
     * @return mixed
     */
    public function getType()
    {
        return $this->type;
    }

    /**
     * @param mixed $type
     */
    public function setType($type)
    {
        $this->type = $type;
    }



}

Entity/Type.php

<?php

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;


/**
 * Type
 *
 * @ORM\Table(name="type")
 * @ORM\Entity(repositoryClass="AppBundle\Repository\TypeRepository")
 */
class Type
{
    /**
     * @ORM\OneToMany(targetEntity="Game", mappedBy="type")
     */
    private $games;

    public function __construct()
    {
        $this->games = new ArrayCollection();
    }
    /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var string
     *
     * @ORM\Column(name="name", type="string", length=255)
     */
    private $name;




    /**
     * Get id
     *
     * @return int
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set name
     *
     * @param string $name
     *
     * @return Type
     */
    public function setName($name)
    {
        $this->name = $name;

        return $this;
    }

    /**
     * Get name
     *
     * @return string
     */
    public function getName()
    {
        return $this->name;
    }

    /**
     * @return mixed
     */
    public function getGames()
    {
        return $this->games;
    }

    /**
     * @param mixed $games
     */
    public function setGames($games)
    {
        $this->games = $games;
    }

}

I'm starting out with Symfony, any help is greatly appreciated!

Use the EntityType:

https://symfony.com/doc/current/reference/forms/types/entity.html

Thanks for the reply, but by now I'm already using that.

I've changed my code so I want to edit my original post, now I'm looking for the edit button... How silly is that

 

I now have selectbox but it replaced my exisiting textfield, I think I know why that is, textfield holds the value for Game.name but the newly added selectbox holds the value of type.name.

 

GameType.php

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add( 'name', EntityType::class, [
                'class' => 'AppBundle:Game',
                'choice_label' => 'name',
                'label' => 'name'
            ] );
        $builder
            ->add( 'name', EntityType::class, [
                'class' => 'AppBundle:Type',
                'choice_label' => 'name',
                'multiple' => false,
                'expanded' => false
            ] );
    }

Could it be that it has something to do with the same property, name?

Yes. Your field name should explain it's value:

public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add( 'game', EntityType::class, [
                'class' => 'AppBundle:Game',
                'choice_label' => 'name',
                'label' => 'name'
            ] )
            ->add( 'type', EntityType::class, [
                'class' => 'AppBundle:Type',
                'choice_label' => 'name',
                'multiple' => false,
                'expanded' => false
            ] );
    }

Afterwards you can access these fields like:

$form->get('game')
// and
$form->get('type')

Hi Ignace,

thanks to your hint I've made the following changes and got it working:

 

GameType:

        $builder
            ->add('name', TextType::class, [
                'attr' => [
                    'class' => 'form-control',
                ],
            ]);
        $builder
            ->add('type', EntityType::class, [
                'class' => 'AppBundle:Type',
                'choice_label' => function ($type) {
                    return $type->getName();
                },
                'multiple' => false,
                'expanded' => false,
                'attr' => [
                    'class' => 'form-control',
                ],

            ]);

game/show.html.twig

    <table>
        <tbody>
            <tr>
                <th>Name</th>
                <td>{{ game.name }}</td>
            </tr>
            <tr>
                <th>Type</th>
                <td>
                    {% if  game.type is not null  %}
                    {{ game.type.name}}
                    {% endif %}
                </td>
            </tr>
        </tbody>
    </table>
