Question

我正在开发一个symfony项目，我有一个表格必须用swiftmailer发送邮件。对于说明 - ＆gt;用户可以使用表单在optionnal文件的上传功能中使用附件。（表单保存在bdd like命令中，我们在提交表单后有一个回顾，以及3个邮件（每次我们不使用附件工作的两个邮件，只有带有atachment选项的邮件当我们失败）有一个要加入的文件，否则如果我们只使用一个评论（其他字段选项，像路径一样工作，邮件正在工作）

我希望我的解释清楚易懂，我的英语不完美，功能也不太容易。一些信息保密的原因我只在这里写了关注邮件的代码，但如果我忘记了什么只是告诉我，我更新帖子。

当我发送没有附件的邮件时，我没有任何问题，但是当我尝试加入文件时，symfony会给我这个错误：

无法打开文件阅读[uploads / 6M.jpg]

我试图在StackOverflow中的其他帖子上获得解决方案，但没有人工作。所以我希望你能帮助我。希望。

命令实体（我已经把关注文件，路径和上传的代码放在附件中（邮件的其余部分和代码工作）：

指挥控制器（同样我只放了关于附件的代码）：

use Symfony\Component\HttpFoundation\Request;
use OrthoBundle\Entity\Compteur;
use Symfony\Bundle\FrameworkBundle\Controller\Controller; 
use OrthoBundle\Entity\Commandes;
use OrthoBundle\Form\Type\CommandesType;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Session\Session;

class FormulaireController extends Controller
{
    public function createFormulaireAction(Request $request)
    {   
        $em = $this->getDoctrine()->getManager();

       $commande = new Commandes();

        $request = $this->get('request');

        $user = $this->getUser();

        $form = $this->createForm(new CommandesType($user), $commande);

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

        ***""""""SOME CODE THAT I DON'T PUT ABOUT PERSIST FLUSH THE COMMAND IN DB""""***

       $message = \Swift_Message::newInstance()
            ->setSubject('Commande n°' . $commande->getId())
            ->setFrom(array('mymail@example.com' => 'send from'))
            ->setTo(array('onemail@example.com' => 'destinatory'))
            ->setCharset('utf-8')
            ->setContentType('text/html')
            ->setBody($this->renderView('@Ortho/Mail/mail_impress.html.twig', array(
                'parentUser' => $user->getParent(),
                'commande' => $commande,
            )));
        if ($commande->getWebPath1() != '') {
            $message->attach(\Swift_Attachment::fromPath($commande->getWebPath1()));
        }
        if ($commande->getWebPath2() != '') {
            $message->attach(\Swift_Attachment::fromPath($commande->getWebPath2()));
        }
        if ($commande->getWebPath3() != '') {
            $message->attach(\Swift_Attachment::fromPath($commande->getWebPath3()));
        }
        if ($commande->getWebPath1() != '' or
            $commande->getWebPath2() != '' or
            $commande->getWebPath3() != '' or
            $commande->getCommentaire() != '') {
            $this->get('mailer')->send($message);              
        }

此代码适用于没有附件的邮件，但如果我尝试在表单上传邮件，则不会。有关信息：文件的上传工作和上传的文件保存在MyApp / web / uploads中。

CommandeType.php：

<?php

namespace MyBundle\Form\Type;

use MyBundle\Entity\Utilisateurs;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\DateType;
use Symfony\Component\Form\Extension\Core\Type\FileType;
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;
use Doctrine\ORM\EntityRepository;

class CommandesType extends AbstractType
{
private $user;

public function __construct(Utilisateurs $utilisateurs)
{
    $this->user = $utilisateurs;
}
/**
 * @param FormBuilderInterface $builder
 * @param array $options
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('commentaireLabo', TextareaType::class, array(
            'attr' => array(
                'placeholder' => 'Select a product'
            ),
        ))
        ->add('file1', FileType::class, array(
            'required' => false
        ))
        ->add('file2', FileType::class, array(
            'required' => false
        ))
        ->add('file3', FileType::class, array(
            'required' => false
        ))
        ->add('commentairePrestataire', TextareaType::class, array(
            'required' => false
        ));
}

/**
 * @param OptionsResolver $resolver
 */
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'MyBundle\Entity\Commandes'

    ));
}

}

这里是视图中有关文件的部分：

<fieldset class="smallbloc"> <!-- Bloc n°3 : Les pièces jointes -->
    <h2 class="fs-title">Pièces jointes complémentaires</h2>
    <h3 class="fs-subtitle">Toutes les pièces jointes à apporter à la commande.</h3>

    {{ form_label(form.file1, "Arcade Maxilaire :") }}
    {{ form_errors(form.file1) }}
    {{ form_widget(form.file1) }}

    {{ form_label(form.file2, "Arcade Mandibulaire :") }}
    {{ form_errors(form.file2) }}
    {{ form_widget(form.file2) }}

    {{ form_label(form.file3, "Autre pièces jointe :") }}
    {{ form_errors(form.file3) }}
    {{ form_widget(form.file3) }}

    {{ form_label(form.commentairePrestataire3D, "Commentaires pour le prestataire 3D :") }}
    {{ form_errors(form.commentairePrestataire3D) }}
    {{ form_widget(form.commentairePrestataire3D) }}

    <input type="hidden" id="monthstat" name="monthstat" value="{{ "now"|date("m-Y") }}">

    <input type="button" name="previous" class="previous action-button" value="Précédent"/>
    <input type="submit" name="previous" class="action-button" value="ENVOYER"/>

    {{ form_rest(form) }}
</fieldset>

我希望每个必要的代码都在这里，并且我没有忘记一些东西，如果不是只是说，我将要更新我的帖子，并添加mising部分。或者，如果我说了一些无脑或者不可理解的东西，只是说我解释。我知道阅读x）并不容易。谢谢你们每个人的帮助。

Answer 1

附加文件时，您必须使用文件系统的绝对路径，例如：

$message->attach(\Swift_Attachment::fromPath($commande->getAbsolutePath1()));

SwiftMailer 运行＆＃34;服务器端＆＃34;，它无法访问您的前端以获取您要附加到邮件中的文件。

PS：您可能还想检查您的文件实际是否存在于应该存在的目录中。也许上传没有按预期工作，文件不存在

Answer 2

我有同样的问题，这是因为地址使用错误

$this->container->get("kernel")->getRootDir()."/../public/".$attac

其中$ attac是您在公共目录中的附件文件地址我使用Symfony flex版本4

symfony2项目上的Swiftmailer附件错误（无法打开文件进行读取）
