Implement UI Fileuploader

Implement UI Fileuploader

I am getting an error when I added image uploader to admin html, according to this reference:

https://magento.stackexchange.com/questions/184731/magento-2-implement-ui-fileuploader

 

However it's getting an error and not uploading an image.

 

There is no error on log files and no way to see what went wrong.

 

A technical problem with the server created an error. Try again to continue what you were doing. If the problem persists, try again later.

Do you have any suggestions to fix the error?

I have tried the code on the link.

I prompts a popup dialog:

 

Attention

The file was not uploaded.

Re: Implement UI Fileuploader

 


Please take look, it's used UI fileuploader component in that extension.

https://github.com/mageprince/magento2-FAQ

1) Add field in admin_form.xml(Admin Form)

 

<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>

 

Now we need to create controller which we define in uploaderConfig in admin form: <item name="url" xsi:type="url" path="vendor_module/faqgroup/upload"/>

 

app/code/Vendor/Module/Controller/Adminhtml/FaqGroup/Upload.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) Create 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) Create 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) Now add arguments for ImageUploader.php in 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>

To save image in database

 

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;
    }
}

To show uploaded image in form edit page:

 

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;
    }
}

Re: Implement UI Fileuploader

Hi @prakash123321

Thanks for your reply.

I have done it as you suggested, it's getting the same issue.

 

I am using my own module and I have to make the file name to 'image' and there is no folder for "FaqGroup", so I copied Upload.php to Controller/Adminhtml.

 

I wonder what comes at the end of this path in Upload.php

    public function _isAllowed()
    {
        return $this->_authorization->isAllowed('Vendor_Module::??????');
    }

 Also what comes in "source" and "url" in di.xml

<field name="image">
    <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">???</item>
            <item name="label" xsi:type="string" translate="true">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="???/index/upload"/>
            </item>
        </item>
    </argument>
</field>

 

 

This is the response from the path/upload/?isAjax=true

Re: Implement UI Fileuploader

I can see only thing is missing is your controller image configuration in di.xml

<type name="QaisarSatti\HelloWorld\Controller\Adminhtml\Index\Upload">
    <arguments>
            <argument name="imageUploader" xsi:type="object">QaisarSatti\HelloWorld\HelloWorldImageUpload</argument>
    </arguments>
</type>

Make sure you set the virtual type for controller too.
