女贞！我是 Symfony 4 的新手，通常是 PHP 和 OOP 的新手。我被帮助使用 FormCollection 制作表单，代码看起来如此

能力控制器.php

/**
     * @Route("/edit", name="ability_edit_all")
     */
    public function edit(Request $request)
    {
        $abilitys = $this->getDoctrine()->getRepository(Ability::class)->findAll();
        $form = $this->createForm(AbilityArrayType::class, ['abilitys' => $abilitys]);
        $form->handleRequest($request);
        if ($form->isSubmitted() && $form->isValid()) {
            foreach ($form->getData()['abilitys'] as $ability){
                $this->getDoctrine()->getManager()->persist($ability);
            }
            $this->getDoctrine()->getManager()->flush();

            $this->addFlash('notice', 'Your changes were saved!');

            return $this->redirectToRoute('ability_edit_all');
        }
        return $this->render('ability/edit.all.html.twig', [
            'form' => $form->createView()
        ]);
    }

和截图在此处输入图像描述

您会看到我的表单记录具有带有choiceType 和简单输入的标签

而且我还用 knp_paginator 弄清楚了自己，因为如果我用 FormCollection 输出超过 15 条记录，我会收到一个关于 php 内存不足的错误。我制作了一个静态表，在其中输出所有记录，排序和过滤工作，分页被破坏了。这是代码

服务文件.php

class AbilityService{
    protected $em;
    protected $container;

    public function __construct(EntityManagerInterface $entityManager, ContainerInterface $container)
    {
        $this->em = $entityManager;
        $this->container = $container;
    }

    public function ReturnData($request){
        $em = $this->em;
        $container = $this->container;
        $query = $em->createQuery(
            '
            SELECT 
                t.idItem,
                t.code,
                t.reloadTime,
                t.durationTime,
                t.idAbilityType
            FROM 
                App\Entity\Ability t
            '
        );
        dump($query);
        //$result = $query->execute();
        $pagenator = $container->get('knp_paginator');
        $results = $pagenator->paginate(
            $query,
            $request->query->getInt('page', 1),
            $request->query->getInt('limit', 10)
        );
        return ($results);
    }
}

和控制器

use App\Service\ServiceFile;
/**
     * @Route("/test-edit", name="ability_test_edit_all")
     */
    public function edit_test(AbilityService $query, Request $request)
    {
        $data = $query->ReturnData($request);

        return $this->render('ability/edit.alltest.html.twig',[
            'form' => $data,
        ]);
    }

工作完美！！

我敢打赌我不知道如何获得相同的结果，但是使用 FormCollection？

第二个问题，如果结果是分页，过滤和排序是否会从 knp_paginator 工作？

好的，好的，发生了一些事情，它不适合我，但分页和排序 + 过滤仅适用于<input>标签，内部<select> <option selected> var </ select>没有任何作用，但解决方案正在运行

控制器文件.php

/**
     * @Route("/edit", name="ability_edit_all")
     */
    public function edit(AbilityService $abilityService, Request $request)
    {
        $data = $abilityService->ReturnData($request);
        $form = $this->createForm(AbilityArrayType::class, ['abilitys' => $data->getItems()]);
        $form->handleRequest($request);
        if ($form->isSubmitted() && $form->isValid()) {
            foreach ($form->getData()['abilitys'] as $properties){
                dump($properties);
                $ability = $this->getDoctrine()->getRepository(Ability::class)->find($properties['id']);
                $ability->setIdItem($properties['idItem']);
                $ability->setCode($properties['code']);
                $ability->setReloadTime($properties['reloadTime']);
                $ability->setDurationTime($properties['durationTime']);
                $ability->setIdAbilityType($properties['idAbilityType']);
                dump($ability);
                $this->getDoctrine()->getManager()->persist($ability);
            }
            $this->getDoctrine()->getManager()->flush();

            $this->addFlash('notice', 'Your changes were saved!');//проделать со всеми см edit.html.twig

            return $this->redirectToRoute('ability_edit_all');
        }
        return $this->render('ability/edit.all.html.twig', [
            'form' => $form->createView(),
            'paginator' => $data
        ]);
    }

树枝模板

{% block title %}Ability edit all{% endblock %}

{% block body %}

    label{display:none}

和ServiceFile.php

<?php
namespace App\Service;

use Symfony\Component\DependencyInjection\ContainerInterface;
use Doctrine\ORM\EntityManagerInterface;
use App\Entity\Ability;

class AbilityService{
    protected $em;
    protected $container;

    public function __construct(EntityManagerInterface $entityManager, ContainerInterface $container)
    {
        $this->em = $entityManager;
        $this->container = $container;
    }

    public function ReturnData($request){
        $em = $this->em;
        $container = $this->container;
        $query = $em->createQuery(
            '
            SELECT 
                t.id,
                t.idItem,
                t.code,
                t.reloadTime,
                t.durationTime,
                t.idAbilityType,
                t.dateCreated,
                t.author,
                t.dateChange,
                t.lastAuthor
            FROM 
                App\Entity\Ability t
            '
        );
        $pagenator = $container->get('knp_paginator');
        $results = $pagenator->paginate(
            $query,
            $request->query->getInt('page', 1),
            $request->query->getInt('limit', 6)
        );
        return ($results);
    }
}

如果有人能告诉如何在内部实现排序<select> <option selected> var </ select>，您可以使用<th> {{knp_pagination_sortable (paginator, 'idItem', 't.idItem')}} </ th> write please！
