我似乎无法理解如何在DataFixture中添加文件上传。我正在尝试上传一个图片,用于我的fixture加载的虚拟内容。这似乎是一个有用的技能。
use Symfony\Component\HttpFoundation\File\UploadedFile;
然后使用copy()函数复制图片,因为ornj说它会移动。
copy($art1->getFixturesPath() . '01.jpg', $art1->getFixturesPath() . '01-copy.jpg');
然后使用以下命令创建并添加文件:
$file = new UploadedFile($art1->getFixturesPath() . '01-copy.jpg', 'Image1', null, null, null, true);
$art1->setFile($file);
$manager->persist($art1);
// Entity file
public function getFixturesPath()
{
return $this->getAbsolutePath() . 'web/uploads/art/fixtures/';
}
''getAbsolutePath()''方法来自Doctrine文件上传。
完整的可工作代码: 实体:

夹具:
<?php
// src/User/MyBundle/DataFixtures/ORM/ArtFixtures.php
namespace User\MyBundle\DataFixtures\ORM;
use Doctrine\Common\DataFixtures\AbstractFixture;
use Doctrine\Common\DataFixtures\OrderedFixtureInterface;
use Doctrine\Common\Persistence\ObjectManager;
use Fredzz\LotwBundle\Entity\Art;
use Symfony\Component\HttpFoundation\File\UploadedFile;
class ArtFixtures extends AbstractFixture implements OrderedFixtureInterface
{
public function load(ObjectManager $manager)
{
$art1 = new Art();
$art1->setTitle('MyTitle');
$art1->setDescription('My description');
copy($art1->getFixturesPath() . '01.jpg', $art1->getFixturesPath() . '01-copy.jpg');
$file = new UploadedFile($art1->getFixturesPath() . '01-copy.jpg', 'Image1', null, null, null, true);
$art1->setFile($file);
$art1->setUser($manager->merge($this->getReference('user-1')));
$manager->persist($art1);
$manager->flush();
}
}
我已经找到了问题的答案。我需要使用类Symfony\Component\HttpFoundation\File\File
来创建文件。Symfony会物理移动文件而不是创建副本,所以您需要为每个fixture拥有一个新文件,或者使用copy()
创建可移动的文件副本。
$image = new Image();
$file = new File('path/to/file.jpg');
$image->file = $file;
$om->persist($image);
类似于这样的东西。
UploadedFile
代替File
!一些bundles(例如VichUploader)会验证文件是否已上传...(实际上我花了一个小时才发现为什么VichUploader无法将我的fixture文件上传到gaufrette。) - Almog Baku您想使用的图像应位于您的“Web”文件夹中,并且在您的数据夹具中只应使用文件指针字符串(即“/web/images/test.png”)。
通常应避免将图像存储在数据库中。
我为 PHP 5.3+ 创建了一个 FileUpload 类。
如何使用?
来自 RFC 3023(XML 媒体类型):
顶级媒体类型“text”对 MIME 实体有一些限制,这些限制在 [RFC2045] 和 [RFC2046] 中描述。特别是,不允许使用 UTF-16 家族、UCS-4 和 UTF-32(除了使用类 MIME 机制的 HTTP[RFC2616])。
仅允许上传 yaml 文件:
<?php
$file = new FileUpload\FileUpload();
$file->setInput( "file" );
$FileUpload->setAllowedMimeTypes(array(
"text/x-yaml", //RFC 3023
"application/x-yaml", // Ruby on Rails
"text/plain",//Possible option( only text plain )
"text/yaml",//Possible option
"text/x-yaml",//Possible option
"application/yaml",//Possible option
));
$file->setDestinationDirectory("/var/www/html/myapp/");
$file->save();
if ($file->getStatus()) {
echo "Okay";
}
?>
所有 MIME 类型的示例:
<?php
$file = new FileUpload\FileUpload();
$file->setInput( "file" );
$file->save();
if ($file->getStatus()) {
echo "is Upload!";
}
?>
