我被这个错误拦住了：
捕获致命错误：参数1传递给 Joker \ CoreBundle \ Entity \ Incidentfile :: setFile（）必须是。的实例 Symfony \ Component \ HttpFoundation \ File \ UploadedFile，字符串给出， 呼唤 /Applications/MAMP/htdocs/joker-repo/vendor/symfony/symfony/src/Symfony/Component/Form/Util/PropertyPath.php 在第538行并在中定义 /Applications/MAMP/htdocs/joker-repo/src/Joker/CoreBundle/Entity/Incidentfile.php 第157行
在我的实体中，我有File的setter和getter。我使用此方法制作文件上传：THIS
文件夹upload_images有权限问题，但在我解决之后一切正常，但现在出了问题。

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

}
}
$spotEntity = $this->getCurrentSpot();
$sentryEntity = $this->getCurrentSentry();
$messagesCollection = $this->getDoctrine()->getRepository('JokerCoreBundle:Message')->findBy(array(

'formfile'=>$formfile->createView(),

)));
}
树枝形式：
<form action="" method="post">
{{ form_rest(formfile) }}
<div class="singleTableForm">
<input style="float: left; margin-left: 338px; " type="submit" name="" class="button" value="Add" />
</div>
</form>
答案 0 :(得分：1)
我发现了什么问题。在树枝上出了问题：
<form action="" method="post" {{ form_enctype(formfile) }}>
只需添加**{{ form_enctype(formfile) }}**

您必须添加注释
/**
* @ORM\PostPersist()
* @ORM\PostUpdate()
*/
public function upload()
查看更多http://symfony.com/doc/current/cookbook/doctrine/file_uploads.html
并显示表单代码
UPD ：最佳方式 - 使用代码{{ form_start(form) }}和{{ form_end(form) }}它还可以保护您免受csrf攻击
