通过CollectionType

我目前正在学习PHP和Symfony。我正在尝试用登录用户创建的食谱制作食谱。在我的食谱创建页面中，我的表单类型包含几个TextType，CollectionType和SubmitType。

这个想法是，当用户创建食谱时，他/她可以向创建的食谱添加成分列表。我的问题是我不能坚持我创建的实体数组。我收到这条消息：

  

类型＆＃34; Doctrine \ Common \ Collections \ Collection | array＆＃34;的预期值对于协会领域＆＃34; AppBundle \ Entity \ Recipe＃$ ingredients＆＃34;，得到＆＃34;字符串＆＃34;代替。

我尝试创建addIngredient()函数，并在ArrayCollection函数中创建了一个新的__construct()。我不知道这是不是我长时间盯着这个问题。

以下是我的实体：

配方实体 

namespace AppBundle\Entity;

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

/**

    protected $id;    

    /**

    private $user;

/**

public function setInstructions($instructions)

    return $this;

/**

public function getCreatedAt()
{
    return $this->created_at;
}

/**

public function setModifiedAt($modifiedAt)
{
    $this->modified_at = $modifiedAt;

    return $this;
}

/**

 */
public function getModifiedAt()
{
    return $this->modified_at;
}

/**

 *
 * @return Recipe
 */
public function setUser(User $user = null)
{
    $this->user = $user;

    return $this;
}

/**
 * Get rUser
 *
 * @return \AppBundle\Entity\User
 */
public function getUser()
{
    return $this->user;
}
}

成分实体 

    namespace AppBundle\Entity;
    use Doctrine\ORM\Mapping as ORM;

/**

class Ingredients
{


    /**

     * @ORM\Column(type="integer")
     */
    protected $id;

    /**

     */
    private $recipe;

    /**
     * @ORM\Column(type="string", length=50)
     *
     */
    private $name;


    /**
     * @return mixed

    public function getRecipe()
    {
        return $this->recipe;
    }

    /**

    public function setRecipe($recipe)

        $this->recipe = $recipe;
    }

    /**

    public function getName()

        return $this->name;
    }

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

我的控制器 

use AppBundle\Entity\Ingredients;
use AppBundle\Entity\Recipe;
use AppBundle\Form\AddRecipeFormType;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;


    class RecipeController extends Controller
    {


        /**
         * @Route("/recipe/new", name = "newRecipe")
         */

        public function addRecipe(Request $request){


            $ingredients = new Ingredients();
            $recipe = new Recipe();
            $user = $this->getUser();
            $recipe->setUser($user);


            $formRecipe = $this->createForm(AddRecipeFormType::class, $recipe);


            $formRecipe->handleRequest($request);

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

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

                $recipe->addIngredients($ingredients);
                $em->persist($recipe);
                $em->flush();

                dump($recipe);
                die;

               //  return $this->redirectToRoute('fos_user_profile_show');
            }


            return $this->render('/CookBook/addRecipe.html.twig', [
                'newRecipe' => $formRecipe->createView(),
            ]);

        }

我的表格 

namespace AppBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\CollectionType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class AddRecipeFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('title', TextType::class)
            ->add('ingredients', CollectionType::class, array(
                'entry_type' => TextType::class,
                'allow_add' => true,
                'prototype' => true

            ))
            ->add('instructions', TextareaType::class)
            ->add('submit', SubmitType::class, array('label' => 'Create Recipe'));
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(['data' => 'AppBundle\Entity\Recipe']);
    }

    public function getBlockPrefix()
    {
        return 'app_bundle_new_recipe_form_type';
    }
}

My Twig（如果有帮助的话） 

{% extends 'base.html.twig' %}

{% block body %}
    <h1>Create your own Recipe</h1>

    {{  form_start (newRecipe) }}
    {{ form_row(newRecipe.title) }}
    <ul id="ingredient-fields-list"
        data-prototype="{{ form_row(newRecipe.ingredients.vars.prototype)|e }}">
        {% for Recipe in newRecipe.ingredients %}
            <li>
                {{ form_errors(newRecipe.ingredients) }}
                {{ form_row(newRecipe.ingredients) }}
            </li>
        {% endfor %}
    </ul>
    <a href="#" id="add-another-ingredient">Add Ingredient</a>
     {{ form_widget(newRecipe) }}

     {{ form_end(newRecipe) }}




{% endblock %}

{% block javascripts %}
    <script type="text/javascript">
        // keep track of how many email fields have been rendered
        var IngredientCount =  '{{ newRecipe.ingredients|length }}';

        jQuery(document).ready(function() {
            jQuery('#add-another-ingredient').click(function(e) {
                e.preventDefault();

                var ingredientList = jQuery('#ingredient-fields-list');

                // grab the prototype template
                var newWidget = ingredientList.attr('data-prototype');
                // replace the "__name__" used in the id and name of the prototype
                // with a number that's unique to your emails
                // end name attribute looks like name="contact[emails][2]"
                newWidget = newWidget.replace("Ingredients", IngredientCount);
                IngredientCount++;

                // create a new list element and add it to the list
                var newLi = jQuery('<li></li>').html(newWidget);
                newLi.appendTo(ingredientList);
            });
        })
    </script>
{% endblock %}

在Recipe中尝试这个

 public function addIngredients($ingredients){
        $this->ingredients[] = $ingredients;
    $ingredients->setRecipe($this);

使用此

更改您的表单 
public function buildForm(FormBuilderInterface $builder, array $options) {
    $builder ->add('title', TextType::class)
        ->add('ingredients', CollectionType::class, array( 'entry_type' => EntityType::class,
            'allow_add' => true, 'prototype' => true ))
        ->add('instructions', TextareaType::class)
        ->add('submit', SubmitType::class, array('label' => 'Create Recipe'));

}
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => Ingredients::class,
    ));
}
