Question

在Symfony 2.8中加载灯具时，我在实施ContainerAwareInterface时遇到以下错误：

PHP Fatal error:  Call to undefined function MeetingBundle\DataFixtures\ORM\User()

如果我不使用此界面，则不会出现此错误。我从官方Symfony documentation获取了示例代码。

文件：

<?php

namespace MeetingBundle\DataFixtures\ORM;

use Doctrine\Common\DataFixtures\FixtureInterface;
use Doctrine\Common\Persistence\ObjectManager;
use Doctrine\Common\DataFixtures\AbstractFixture;
use Doctrine\Common\DataFixtures\OrderedFixtureInterface; 
use Symfony\Component\DependencyInjection\ContainerAwareInterface;
use Symfony\Component\DependencyInjection\ContainerInterface;
use MeetingBundle\Entity\User;

//C:\Bitnami\wampstack-5.6.20-0\apache2\htdocs\sym_prog\just2\src\MeetingBundle\DataFixtures\ORM\LoadUsers01Loader.php


/*
  Class LoadUsers01
 @package Meeting\DataFixtures\ORM
 */
class LoadUsers01Loader extends AbstractFixture implements OrderedFixtureInterface, ContainerAwareInterface {

     /**
     * @var ContainerInterface
     */
    private $container;


    public function setContainer(ContainerInterface $container = null)
    {
        $this->container = $container;
    }


    /*
      {@inheritDoc}
     */
    public function load(ObjectManager $manager)
    {
        for ($i = 1; $i <= 10; $i++) {
            $fuser = new User();
            $fuser->setUsername('name'.$i);
            $fuser->setEmail('g.statkute'.$i.'@gmail.com');
            $fuser->setIsActive(1); //also tried to use true
                $encoder = $this->container->get('security.password_encoder');
                $encodedPsswd = $encoder->encodePassword($user, 'pswd'.$i);
            //$fuser->setPassword('pswd'.$i);
            $fuser->setPassword($encodedPsswd);
            $manager->persist($fuser);
            $this->addReference('fuser:name'.$i, $fuser);
        }

        $manager->flush();
    }

        public function getOrder()
    {
        return 1;
    }
}

完整错误：

c:\Bitnami\wampstack-5.6.20-0\apache2\htdocs\sym_prog\just2>php app/console doctrine:fixtures:load

我不知道ContainerAwareInterface如何导致此错误？如果我没有实现它并使用没有编码器的普通密码，则夹具会加载到数据库中。

实际上，忽略此错误并进一步工作，我开始得到其他命名空间错误。例如，symfony尝试从命名空间“MeetingBundle \ Entity \ Doctrine \ Common \ Collections”加载类“ArrayCollection”。命名空间有问题。要解决这个问题吗？

src\MeetingBundle\Entity\User.php
namespace MeetingBundle\Entity;
use Doctrine\Common\Collections\ArrayCollection;
/**
 * User
 *
 * @ORM\Table(name="tuser")
 * @ORM\Entity(repositoryClass="MeetingBundle\Repository\UserRepository")
 */
class User implements AdvancedUserInterface, EquatableInterface, \Serializable

<...>
    /**
     * @ORM\ManyToMany(targetEntity="Role", inversedBy="users")
     *
     */
    private $roles;

 public function __construct() {
 $this->roles = new Doctrine\Common\Collections\ArrayCollection();
<...>

创建用户时会出现错误：

Attempted to load class "ArrayCollection" from namespace "MeetingBundle\Entity\Doctrine\Common\Collections".
Did you forget a "use" statement for "Doctrine\Common\Collections\ArrayCollection"?

Answer 1

首先，您在new之前忘记了User()运算符，因此PHP将其视为函数调用。

更改此行：

$fuser = User();

到：

$fuser = new User();

此外，您正在使用行中不存在的$user变量：

$encodedPsswd = $encoder->encodePassword($user, 'pswd'.$i);

您应该将其更改为使用$fuser：

$encodedPsswd = $encoder->encodePassword($fuser, 'pswd'.$i);

Answer 2

此：

        $fuser = User();

和

 use MeetingBundle\Entity\User;

User命名空间中没有MeetingBundle\DataFixtures\ORM个函数。它可能在MeetingBundle\Entity\User结束，所以你可能想要

$fuser = MeetingBundle\Entity\User\User();

代替。

PHP致命错误：调用未定义的函数，而不是使用ContainerAwareInterface加载fixture
