我拥有当前版本的symfony和sonata管理软件包，并需要一个表单在我的管理员多个图像上传。
I have the current version of symfony and of the sonata admin bundle and need a form in my admin with multiple image uploads.
我提供的以下代码基于此安装文档：
The following code I present is based on this installation documentation:
http://sonata-project.org/bundles/admin/master/doc/reference/recipe_file_uploads.html
在我的情况下，我的包中有一个实体项目（Pf\Bundle\BlogBundle\Entity\Projects.php）。在这个实体中，我有$ image1（相当于文档中的文件名），当然还有未映射的属性文件。所有的字符串和配置，因为它必须是。 （请注意，在我的案例中，我使用的是image1而不是文件名）。
In my case I have an entity Projects (Pf\Bundle\BlogBundle\Entity\Projects.php) in my bundle. In this entity I have $image1 (which is the equivalent of filename in the doc) and of course the unmapped property file. All strings and configured as it has to be. (Note that I use image1 instead of filename in my case // documentation).
<?php
namespace Pf\Bundle\BlogBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Component\Validator\Constraints as Assert;
/**
* Projects
*
* @ORM\Table()
* @ORM\Entity(repositoryClass="Pf\Bundle\BlogBundle\Entity\ProjectRepository")
* @ORM\HasLifecycleCallbacks()
*/
class Projects
{
const SERVER_PATH_TO_IMAGE_FOLDER = '/uploads/medias';
/**
* Unmapped property to handle file uploads
*/
private $file;
/**
* Sets file.
*
* @param UploadedFile $file
*/
public function setFile(UploadedFile $file = null)
{
$this->file = $file;
}
/**
* Get file.
*
* @return UploadedFile
*/
public function getFile()
{
return $this->file;
}
/**
* Manages the copying of the file to the relevant place on the server
*/
public function upload()
{
// the file property can be empty if the field is not required
if (null === $this->getFile()) {
return;
}
// we use the original file name here but you should
// sanitize it at least to avoid any security issues
// move takes the target directory and target filename as params
$this->getFile()->move(
Projects::SERVER_PATH_TO_IMAGE_FOLDER,
$this->getFile()->getClientOriginalName()
);
// set the path property to the filename where you've saved the file
$this->image1 = $this->getFile()->getClientOriginalName();
// clean up the file property as you won't need it anymore
$this->setFile(null);
}
/**
* Lifecycle callback to upload the file to the server
*/
public function lifecycleFileUpload() {
$this->upload();
}
/**
* Updates the hash value to force the preUpdate and postUpdate events to fire
*/
public function refreshUpdated() {
$this->setUpdated(date('Y-m-d H:i:s'));
}
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="image1", type="string", length=100)
*/
private $image1;
//...
/**
* @var datetime
*
* @ORM\Column(name="updated", nullable=true)
*/
private $updated;
/**
* Set updated
*
* @param string $updated
* @return Projects
*/
public function setUpdated($updated)
{
$this->updated = $updated;
return $this;
}
/**
* Get updated
*
* @return string
*/
public function getUpdated()
{
return $this->updated;
}
}
我还有一个管理控制器（Pf\Bundle \BlogBundle\Admin\ProjectsAdmin.php）其中我有以下表单（在sonata管理方式中创建）：
I also have an admin controller (Pf\Bundle\BlogBundle\Admin\ProjectsAdmin.php) where I have the following form (created in the "sonata admin way"):
<?php
namespace Pf\Bundle\BlogBundle\Admin;
use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Validator\ErrorElement;
use Sonata\AdminBundle\Form\FormMapper;
class ProjectsAdmin extends Admin
{
// setup the default sort column and order
protected $datagridValues = array(
'_sort_order' => 'DESC',
'_sort_by' => 'id'
);
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('file', 'file', array('required' => false, 'data_class' => null))
->add('image2', 'text')
->add('image3', 'text')
->add('link', 'text')
->add('download_link', 'text')
->add('content1', 'text')
->add('content2', 'text')
->add('title', 'text')
->add('thumbnail', 'text')
;
}
public function prePersist($projects) {
$this->manageFileUpload($projects);
}
public function preUpdate($projects) {
$this->manageFileUpload($projects);
}
private function manageFileUpload($projects) {
if ($projects->getFile()) {
$projects->refreshUpdated();
}
}
protected function configureDatagridFilters(DatagridMapper $datagridMapper)
{
$datagridMapper
->add('title')
;
}
protected function configureListFields(ListMapper $listMapper)
{
$listMapper
->addIdentifier('title')
;
}
}
我有几个问题：
-
如果我尝试创建一个新项目，image1似乎是空的
每次我尝试上传。我可以使其在实体中为空，但
那么我根本就不会在数据库中获取任何url
If I try to CREATE A NEW project, the image1 appears to be null every time I try to upload. I can make it nullable in the entity but then I don't get any url at all in the database
执行INSERT INTO Projects时发生异常...
完整性约束违规：1048列'image1'不能为空
An exception occurred while executing 'INSERT INTO Projects... Integrity constraint violation: 1048 Column 'image1' cannot be null
通过在管理员中编辑现有项目，似乎工作..well几乎。我上传文件时没有任何错误，但是我在数据库中获得一个临时路径，没有文件已被移动到好的文件夹。
By editing an existing project in the admin, it seems to work..well nearly..I don't get any errors when uploading the file BUT I get a temporary path in the database and no file has been moved in the good folder.
看起来上传功能没有被调用。我尝试调试它，但找不到解决方案。
It looks like the upload function isn't called. I try to debug it but can't find a solution.
我已经按照一步一步的文档。唯一的区别是我不使用任何.yaml文件配置我的实体..我必须？我在symfony上使用注释，我想在同一时间使用orm.yaml和注释是不好的...对吗？
I have followed step by step the documentation. The only difference is that I don't use any .yaml file to configure my entity.. Does I have to? I'm using annotations on my symfony, I guess it's not good to use orm.yaml and annotation in the same time...right?
任何帮助超过欢迎！
推荐答案
这个话题的任何信息
你看过 http://symfony.com/doc/current/cookbook/form/form_collections.html ？
您应该将图像表单嵌入到父表单中。例如，
You should embed image form into the parent form. For instance,
- > add（'myImage'，'collection'，array（'type'=> new MyImageType（） ）
而不是放置多个image1，image2，...使另一个表单类，例如。 MyImageType（）并将其作为集合类型添加到现有的表单中。
Instead of putting multiple image1, image2,... make another form class, eg. MyImageType() and add it as a collection type in to an existing form.
在这个方向上工作，祝你好运。
Work in that direction, good luck.
