Symfony, embedded 5 or 6 entities without relation in the one form

NEIRANG
PHP Symfony

Bonjour,

Voila je rencontre un petit problème avec mon code.
Dans mon cas, j'ai 30 entités qu'il n'y a pas de relation entre eux et toutes les entités ont deux colonnes. Je voulais avoir 6 ou 7 entités dans une forme, mais je ne sais pas quelle est la meilleure façon de le faire? ceci est mon code ...

ceci est mon contrôleur:

public function general1Action(Request $request)
{
    $example1 = new Example1();
    $example2 = new Example2();
    $example3 = new Example3();
    $example4 = new Example4();

    $formexample1 = $this->createForm('...Bundle\Form\Example1Type', $example1);
    $formexample2 = $this->createForm('...Bundle\Form\ Example2Type', $example2);
    $formexample3 = $this->createForm('...Bundle\Form\ Example3Type', $example3);
    $fprmexample4 = $this->createForm('...Bundle\Form\Example4Type', $example4);

    $example1->handleRequest($request);
    $example2->handleRequest($request);
    $example3->handleRequest($request);
    $example4->handleRequest($request);

    $em = $this->getDoctrine()->getManager();

    if ($example1->isSubmitted() && $example1->isValid()) {

            /**
            * To generate the value example1 first column(e1fc) and second       column(e1sc)
            */

            $prefix=$this->container->getParameter('prefix');         
            $e1fcCle=$em->getRepository("...Bundle:Example1")->genereCle('Example1',$prefix);
            $example1->sete1fc($e1fcCle);

            /**
            * To generate the value example1 second column(e1sc)
            */
            $example1->sete1sc("e1sc".($e1fcCle));

            /**
            * to check, the fields are not empty
            */ 
            if(($formexample2["e2sc"]->getData())!=""){
                $example2->sete1fc($e1fcCle);
                $em->persist($example2);
            } 
            if(($formexample3["e3sc"]->getData())!=""){
                $example3->sete1fc($e1fcCle);
                $em->persist($example3);
            }
            if(($formexample4["e4sc"]->getData())!=""){
                 $example4-> sete1fc($e1fcCle);                 
                $em->persist($example4);
            }

            $em->persist($example1);
            $em->flush();

                return $this->forward('...Bundle:General...: general2',
                        array('E1FC' => $e1fcCle));
    }

    return $this->render('.../general1.html.twig', array(
        'example1' => $example1,
        'formExample1' => $formexample1->createView(),
        'formExample2' => $formexample2->createView(),
        'formExample3' => $formexample3->createView(),
        'formExample4' => $formexample4->createView(),
    ));

}` ```

and this is my general1.html.twig :

{% extends 'base.html.twig' %}
{% block body %}
{{ form_start(formExample1) }}
{{ form_row(formExample2.e2sc) }}
{{ form_row(formExample3.e3sc) }}
{{ form_row(formExample4.e4sc) }}
<input type="submit" value="Next" />
{{ form_widget(formExample1._token) }}  
{{ form_end(formExample1, {"render_rest":false}) }}
<ul>
    <li>
        <a href="{{ path('..._index') }}">Back to the list</a>
    </li>
</ul>
{% endblock %}`,

I have another question : when i try to use isValid() for the other form like this

if(($formexample2["e2sc"]->getData())!=""&& $example2->isValid())

i have this error: Fatal error: Call to a member function get...() on null

Bonjour,

Pour chaque type d'entité, créer une classe formulaire (sans submit), ex Entity1Type pour Entity1

namespace AppBundle\Form;

use AppBundle\Form;
//...

class Entity1Type extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add("prop_one", ...)
            ->add("prop_two", ...)
            //.... etc...
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            "data_class"=>Entity1::class
        ]);
    }
}

Créer un objet qui rassemble les entites que tu veux mettre dans ton formulaire

namespace AppBundle\Form\Model;

class MyModel {

    /**
     * @var \AppBundle\Entity\Entity1
     * @Assert\Valid()
     */
    private $entity1;
    /**
     * @var \AppBundle\Entity\Entity2
     * @Assert\Valid()
     */
    private $entity2;
    /**
     * @var \AppBundle\Entity\Entity3
     * @Assert\Valid()
     */
    private $entity3;
    /**
     * @var \AppBundle\Entity\Entity4
     * @Assert\Valid()
     */
    private $entity4;

    //... etc ...

    // getters & setters ...
}

Créer une classe formulaire pour MyModel :

namespace AppBundle\Form;

use AppBundle\Form\Model\MyModel;
//...

class MyModelForm extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add("entity1", Entity1Type::class, [...])
            ->add("entity2", Entity2Type::class, [...])
            ->add("entity3", Entity3Type::class, [...])
            ->add("entity4", Entity4Type::class, [...])

            //.... etc ...

            ->add("submit", SubmitType::class, ["label"=>"Enregistrer"])

    ;
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            "data_class"=>MyModel::class
        ]);
    }
}

dans ton controller :

public function monactionAction(Request $request)
{
        // ...

        $model = new MyModel();
        $model->setEntity1($entity1)->setEntity2($entity2)....... etc;

        $form = $this->createForm(MyModelForm::class, $model);

        $form->handleRequest($request);
        if($form->isValid()){

            // ici les entités ont leurs nouvelles valeurs
            // ... code 'maison', persistence, ...
            // redirection

        }

        return $this->render("mapage.html.twig", ["form"=>$form->createView()];
}
