我似乎无法理解如何将文件上传到DataFixture。我正在尝试为我的固定装置加载的虚拟内容上传一个图像。这似乎是一件有用的事情。
尽管一年前就有人问过这个问题,但似乎没有太多关于如何通过条令数据固定装置上传文件的信息。我只能找到这个帖子。
我一直在寻找,我采取了与ornj略有不同的方法。(可能与Symfony的更新有关。)
我第一次去
use Symfony'Component'HttpFoundation'File'UploadedFile;
然后使用copy()复制图像,因为正如ornj所说,它会移动图像。
copy($art1->getFixturesPath() . '01.jpg', $art1->getFixturesPath() . '01-copy.jpg');
然后使用创建并添加文件
$file = new UploadedFile($art1->getFixturesPath() . '01-copy.jpg', 'Image1', null, null, null, true);
$art1->setFile($file);
$manager->persist($art1);
如果我没有在"UploadedFile"构造函数中将最后一个参数设置为"true",因为它在运行"octrine:fixtures:load"时引发未知错误。此参数为"测试模式是否处于活动状态"。看到它是一个固定装置,设置为测试模式是有意义的。
方法"getFixturesPath()"只检索存储样本图像的路径:
// Entity file
public function getFixturesPath()
{
return $this->getAbsolutePath() . 'web/uploads/art/fixtures/';
}
"getAbsolutePath()"方法已从Doctrine文件上载中获取。
完整的工作代码:实体:

夹具:
<?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();
}
}
希望这能帮助到别人!如果出了问题,我很抱歉。我还在学习:)
我找到了问题的答案。我需要使用类Symfony'Component'HttpFoundation'File'File
来创建一个文件。Symfony将物理移动文件,而不是创建副本,因此您需要为每个固定装置创建一个新文件,使用copy()
创建可以移动的文件副本。
$image = new Image();
$file = new File('path/to/file.jpg');
$image->file = $file;
$om->persist($image);
类似的东西。
您想要使用的图像应该位于"Web"文件夹中,并且您应该只在数据固定装置中使用文件指针字符串(即"/Web/images/test.png")。
您通常应该避免在数据库中存储图像。
我为PHP 5.3+创建了一个FileUpload类
如何使用?:
文档
来自RFC 3023(XML媒体类型):
顶级媒体类型"text"对MIME实体有一些限制并且它们在[RFC2045]和[RFC2046]中进行了描述。特别是不允许使用UTF-16家族、UCS-4和UTF-32(超过HTTP[RFC2616],其使用类似MIME的机制)。
只允许上传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!";
}
?>
