Sigo estos pasos para agregar el componente UI fileuploader en forma de administrador
Utilizo el componente UI fileuploader para cargar un icono para mi extensión de preguntas frecuentes. Puede tomar referencia desde aquí: https://github.com/mageprince/magento2-FAQ
1) Agregar campo en admin_form.xml(Formulario de administrador)
<field name="icon">
<argument name="data" xsi:type="array">
<item name="config" xsi:type="array">
<item name="dataType" xsi:type="string">string</item>
<item name="source" xsi:type="string">FaqGroup</item>
<item name="label" xsi:type="string" translate="true">Group Image</item>
<item name="visible" xsi:type="boolean">true</item>
<item name="formElement" xsi:type="string">fileUploader</item>
<item name="elementTmpl" xsi:type="string">ui/form/element/uploader/uploader</item>
<item name="previewTmpl" xsi:type="string">Vendor_Module/image-preview</item>
<item name="required" xsi:type="boolean">false</item>
<item name="sortOrder" xsi:type="number">40</item>
<item name="uploaderConfig" xsi:type="array">
<item name="url" xsi:type="url" path="your_router/faqgroup/upload"/>
</item>
</item>
</argument>
</field>
2) Ahora necesitamos crear un controlador que definimos en uploaderConfigforma de administrador:<item name="url" xsi:type="url" path="vendor_module/faqgroup/upload"/>
app / code / Vendor / Module / Controller / Adminhtml / FaqGroup / Upload.php
<?php
namespace Vendor\Module\Controller\Adminhtml\FaqGroup;
use Magento\Framework\Controller\ResultFactory;
class Upload extends \Magento\Backend\App\Action
{
public $imageUploader;
public function __construct(
\Magento\Backend\App\Action\Context $context,
\Vendor\Module\Model\ImageUploader $imageUploader
) {
parent::__construct($context);
$this->imageUploader = $imageUploader;
}
public function _isAllowed()
{
return $this->_authorization->isAllowed('Vendor_Module::Faq');
}
public function execute()
{
try {
$result = $this->imageUploader->saveFileToTmpDir('icon');
$result['cookie'] = [
'name' => $this->_getSession()->getName(),
'value' => $this->_getSession()->getSessionId(),
'lifetime' => $this->_getSession()->getCookieLifetime(),
'path' => $this->_getSession()->getCookiePath(),
'domain' => $this->_getSession()->getCookieDomain(),
];
} catch (\Exception $e) {
$result = ['error' => $e->getMessage(), 'errorcode' => $e->getCode()];
}
return $this->resultFactory->create(ResultFactory::TYPE_JSON)->setData($result);
}
}
3) Crear ImageUploader.php
app / code / Vendor / Module / Model / ImageUploader.php
<?php
namespace Prince\Faq\Model;
class ImageUploader
{
private $coreFileStorageDatabase;
private $mediaDirectory;
private $uploaderFactory;
private $storeManager;
private $logger;
public $baseTmpPath;
public $basePath;
public $allowedExtensions;
public function __construct(
\Magento\MediaStorage\Helper\File\Storage\Database $coreFileStorageDatabase,
\Magento\Framework\Filesystem $filesystem,
\Magento\MediaStorage\Model\File\UploaderFactory $uploaderFactory,
\Magento\Store\Model\StoreManagerInterface $storeManager,
\Psr\Log\LoggerInterface $logger
) {
$this->coreFileStorageDatabase = $coreFileStorageDatabase;
$this->mediaDirectory = $filesystem->getDirectoryWrite(\Magento\Framework\App\Filesystem\DirectoryList::MEDIA);
$this->uploaderFactory = $uploaderFactory;
$this->storeManager = $storeManager;
$this->logger = $logger;
$this->baseTmpPath = "faq/tmp/icon";
$this->basePath = "faq/icon";
$this->allowedExtensions= ['jpg', 'jpeg', 'gif', 'png'];
}
public function setBaseTmpPath($baseTmpPath)
{
$this->baseTmpPath = $baseTmpPath;
}
public function setBasePath($basePath)
{
$this->basePath = $basePath;
}
public function setAllowedExtensions($allowedExtensions)
{
$this->allowedExtensions = $allowedExtensions;
}
public function getBaseTmpPath()
{
return $this->baseTmpPath;
}
public function getBasePath()
{
return $this->basePath;
}
public function getAllowedExtensions()
{
return $this->allowedExtensions;
}
public function getFilePath($path, $imageName)
{
return rtrim($path, '/') . '/' . ltrim($imageName, '/');
}
public function moveFileFromTmp($imageName)
{
$baseTmpPath = $this->getBaseTmpPath();
$basePath = $this->getBasePath();
$baseImagePath = $this->getFilePath($basePath, $imageName);
$baseTmpImagePath = $this->getFilePath($baseTmpPath, $imageName);
try {
$this->coreFileStorageDatabase->copyFile(
$baseTmpImagePath,
$baseImagePath
);
$this->mediaDirectory->renameFile(
$baseTmpImagePath,
$baseImagePath
);
} catch (\Exception $e) {
throw new \Magento\Framework\Exception\LocalizedException(
__('Something went wrong while saving the file(s).')
);
}
return $imageName;
}
public function saveFileToTmpDir($fileId)
{
$baseTmpPath = $this->getBaseTmpPath();
$uploader = $this->uploaderFactory->create(['fileId' => $fileId]);
$uploader->setAllowedExtensions($this->getAllowedExtensions());
$uploader->setAllowRenameFiles(true);
$result = $uploader->save($this->mediaDirectory->getAbsolutePath($baseTmpPath));
if (!$result) {
throw new \Magento\Framework\Exception\LocalizedException(
__('File can not be saved to the destination folder.')
);
}
$result['tmp_name'] = str_replace('\\', '/', $result['tmp_name']);
$result['path'] = str_replace('\\', '/', $result['path']);
$result['url'] = $this->storeManager
->getStore()
->getBaseUrl(
\Magento\Framework\UrlInterface::URL_TYPE_MEDIA
) . $this->getFilePath($baseTmpPath, $result['file']);
$result['name'] = $result['file'];
if (isset($result['file'])) {
try {
$relativePath = rtrim($baseTmpPath, '/') . '/' . ltrim($result['file'], '/');
$this->coreFileStorageDatabase->saveFile($relativePath);
} catch (\Exception $e) {
$this->logger->critical($e);
throw new \Magento\Framework\Exception\LocalizedException(
__('Something went wrong while saving the file(s).')
);
}
}
return $result;
}
}
4) Crear image-preview.html
app / code / Vendor / Module / view / adminhtml / web / template / image-preview.html
<div class="file-uploader-summary">
<div class="file-uploader-preview">
<a attr="href: $parent.getFilePreview($file)" target="_blank">
<img
class="preview-image"
tabindex="0"
event="load: $parent.onPreviewLoad.bind($parent)"
attr="
src: $parent.getFilePreview($file),
alt: $file.name">
</a>
<div class="actions">
<button
type="button"
class="action-remove"
data-role="delete-button"
attr="title: $t('Delete image')"
click="$parent.removeFile.bind($parent, $file)">
<span translate="'Delete image'"/>
</button>
</div>
</div>
<div class="file-uploader-filename" text="$file.name"/>
<div class="file-uploader-meta">
<text args="$file.previewWidth"/>x<text args="$file.previewHeight"/>
</div>
</div>
5) Ahora agregue argumentos para ImageUploader.phpen di.xml
app / code / Vendor / Module / etc / di.xml
<type name="Vendor\Module\Model\ImageUploader">
<arguments>
<!-- Temporary file stored in pub/media/faq/tmp/icon -->
<argument name="baseTmpPath" xsi:type="string">faq/tmp/icon</argument>
<argument name="basePath" xsi:type="string">faq/icon</argument>
<argument name="allowedExtensions" xsi:type="array">
<item name="jpg" xsi:type="string">jpg</item>
<item name="jpeg" xsi:type="string">jpeg</item>
<item name="gif" xsi:type="string">gif</item>
<item name="png" xsi:type="string">png</item>
</argument>
</arguments>
</type>
Verifique este archivo para cargar la imagen cargada en el formulario de edición: DataProvider.php
SALIDA:
Para guardar la imagen en la base de datos
app / code / Vendor / Module / Controller / Adminhtml / Save.php
<?php
namespace Vendor\Module\Controller\Adminhtml;
use Magento\Framework\Exception\LocalizedException;
class Save extends \Magento\Backend\App\Action
{
protected $dataPersistor;
public function __construct(
\Magento\Backend\App\Action\Context $context,
\Magento\Framework\App\Request\DataPersistorInterface $dataPersistor
) {
$this->dataPersistor = $dataPersistor;
parent::__construct($context);
}
public function execute()
{
...
...
$data = $this->_filterFoodData($data);
$model->setData($data);
$model->save();
...
...
}
public function _filterFoodData(array $rawData)
{
//Replace icon with fileuploader field name
$data = $rawData;
if (isset($data['icon'][0]['name'])) {
$data['icon'] = $data['icon'][0]['name'];
} else {
$data['icon'] = null;
}
return $data;
}
}
Para mostrar la imagen cargada en la página de edición de formulario:
app / code / Vendor / Module / Model / DataProvider.php
<?php
namespace Vendor\Module\Model;
use Magento\Store\Model\StoreManagerInterface;
class DataProvider extends \Magento\Ui\DataProvider\AbstractDataProvider
{
...
...
public function getData()
{
...
...
$items = $this->collection->getItems();
//Replace icon with fileuploader field name
foreach ($items as $model) {
$this->loadedData[$model->getId()] = $model->getData();
if ($model->getIcon()) {
$m['icon'][0]['name'] = $model->getIcon();
$m['icon'][0]['url'] = $this->getMediaUrl().$model->getIcon();
$fullData = $this->loadedData;
$this->loadedData[$model->getId()] = array_merge($fullData[$model->getId()], $m);
}
}
...
...
return $this->loadedData;
}
public function getMediaUrl()
{
$mediaUrl = $this->storeManager->getStore()
->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA).'faq/tmp/icon/';
return $mediaUrl;
}
}
