Magento 2 将自定义图像属性添加到客户资料并显示缩略图

Question

这里是 Magento 2 新手。 我已经构建了一个扩展，可以将自定义属性添加到客户对象。属性在数据库中并显示在表单上。 我的问题是我称之为“photo_id”的图像属性。实际上传、保存图像、显示缩略图的正确方法是什么，单击时会扩展为完整图像？见下图

这是我的 installData.php

namespace Lemon\Veripass\Setup;

use Magento\Customer\Model\Customer;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

class InstallData implements \Magento\Framework\Setup\InstallDataInterface
{
private $eavSetupFactory;

private $eavConfig;

private $attributeResource;

public function __construct(
    \Magento\Eav\Setup\EavSetupFactory $eavSetupFactory,
    \Magento\Eav\Model\Config $eavConfig,
    \Magento\Customer\Model\ResourceModel\Attribute $attributeResource
) {
    $this->eavSetupFactory = $eavSetupFactory;
    $this->eavConfig = $eavConfig;
    $this->attributeResource = $attributeResource;
}

public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
    $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
    $eavSetup->addAttribute(
        \Magento\Customer\Model\Customer::ENTITY,
        'is_verified',
        [
            'type'         => 'int',
            'label'        => 'Verified',
            'input'        => 'boolean',
            'required'     => false,
            'visible'      => true,
            'user_defined' => true,
            'position'     => 999,
            'system'       => 0,
        ]
    );
    $verifiedAttribute = $this->eavConfig->getAttribute(Customer::ENTITY, 'is_verified');

    // more used_in_forms ['adminhtml_checkout','adminhtml_customer','adminhtml_customer_address','customer_account_edit','customer_address_edit','customer_register_address']
    $verifiedAttribute->setData(
        'used_in_forms',
        ['adminhtml_customer']

    );
    $verifiedAttribute->save();

    $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);

    $eavSetup->addAttribute(Customer::ENTITY, 'photo_id', [
        'type' => 'varchar',
        'label' => 'Photo ID',
        'input' => 'image',
        'required' => false,
        'visible' => true,
        'user_defined' => true,
        'sort_order' => 1000,
        'position' => 1000,
        'system' => 0,
    ]);

    $attribute = $this->eavConfig->getAttribute(Customer::ENTITY, 'photo_id');
    $attribute->setData('used_in_forms', ['adminhtml_customer','customer_account_edit']);
    $this->attributeResource->save($attribute);
}
}

我的 customer_form.xml

    <?xml version="1.0" encoding="UTF-8"?>
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <fieldset name="customer">
        <field name="is_verified" formElement="checkbox">
            <settings>
                <visible>true</visible>
            </settings>
        </field>
        <field name="photo_id" formElement="image">
            <settings>
                <visible>true</visible>
            </settings>
        </field>
    </fieldset>
</form>

您可以像示例一样使用此代码。 customer_form.xml

<field name="photo_image" sortOrder="40" formElement="fileUploader">
   <argument name="data" xsi:type="array">
      <item name="config" xsi:type="array">
         <item name="source" xsi:type="string">customer</item>
       </item>
    </argument>
    <settings>
         <elementTmpl>ui/form/element/uploader/uploader</elementTmpl>
         <dataType>string</dataType>
         <label translate="true">Photo Image</label>
         <visible>true</visible>
         <required>true</required>
    </settings>
    <formElements>
        <fileUploader>
            <settings>
              <required>false</required>
              <uploaderConfig>
                  <param xsi:type="url" name="url" path="your_module_router/media/upload"/>
              </uploaderConfig>
              <previewTmpl>Magento_Catalog/image-preview</previewTmpl>
            </settings>
      </fileUploader>
    </formElements>
 </field>

Namspace_Module/Controller/Adminhtml/Media/Upload.php

/**
 * Class Upload
 */
class Upload extends \Magento\Backend\App\Action
{
    /**
     * Image uploader
     *
     * @var \Magento\Catalog\Model\ImageUploader
     */
    protected $imageUploader;

    /**
     * Upload constructor.
     *
     * @param \Magento\Backend\App\Action\Context $context
     * @param \Magento\Catalog\Model\ImageUploader $imageUploader
     */
    public function __construct(
        \Magento\Backend\App\Action\Context $context,
        \Magento\Catalog\Model\ImageUploader $imageUploader
    ) {
        parent::__construct($context);
        $this->imageUploader = $imageUploader;
    }

    /**
     * Check admin permissions for this controller
     *
     * @return boolean
     */
    protected function _isAllowed()
    {
        return $this->_authorization->isAllowed('Mageaddons_Customs::customs');
    }

    /**
     * Upload file controller action
     *
     * @return \Magento\Framework\Controller\ResultInterface
     */
    public function execute()
    {
        $imageId = $this->_request->getParam('param_name', 'image');

        try {
            $result = $this->imageUploader->saveFileToTmpDir($imageId);

            $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);
    }
}

注意：此代码示例可帮助您添加，因此如果希望此代码正常工作，您必须修改您的模块的权限
