TYPO3 10 通过扩展模型从前端上传多张图片

Question

我正在尝试扩展Ext:cart 的模型。当有人从购物车页面订购产品时。我愿意接受来自用户的图片。

我已经添加了以下配置。

配置/TCA/Overrides/tx_cart_domain_model_order_item.php

<?php

$temporaryColumns = [
    'images' => [
        'exclude' => 0,
            'label' => 'Upload Image',

                // custom configuration for displaying fields in the overlay/reference table

    $temporaryColumns

ext_localconf.php

$dispatcher = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Extbase\SignalSlot\Dispatcher::class);
$dispatcher->connect(

    'changeOrderItemBeforeSaving',
    \vendor\myext\Utility\OrderUtility::class,
    'changeOrderItemBeforeSaving'
);

$GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects'][\Extcode\Cart\Domain\Model\Order\Item::class] = [
    'className' => \vendor\myext\Domain\Model\Order\Item::class
];

\TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Extbase\Object\Container\Container::class)
    ->registerImplementation(
        \Extcode\Cart\Domain\Model\Order\Item::class,
        \vendor\myext\Domain\Model\Order\Item::class
    );

配置/Extbase/Persistence/Classes.php

<?php
declare(strict_types = 1);

return [

        'tableName' => 'tx_cart_domain_model_order_item'
    ],

class Item extends \Extcode\Cart\Domain\Model\Order\Item
{

    /**

}

现在，我创建了一个实用程序类来在下订单时修改 orderItem。但是，我没有得到扩展的图像字段。

<?php

namespace vendor\myext\Utility;

/*
 * This file is part of the package extcode/cart.
 *
 * For the full copyright and license information, please read the
 * LICENSE file that was distributed with this source code.
 */

use TYPO3\CMS\Core\Utility\GeneralUtility;

class OrderUtility
{
    /**
     * @param array $params
     *
     * @return array
     */
    public function changeOrderItemBeforeSaving(array $params) {
        \TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($params);die;
    }
}

任何人都可以指导如何使用 FAL 图像扩展任何扩展并使用独立扩展进行扩展。

有点晚了，但在几年前的一个 9.5 项目中，我创建了一个辅助类来将媒体附加到对象上。这仅限于图像、Youtube 和 Vimeo，但如果需要，也不太难扩展到其他媒体类型。这并不理想，但它正在工作，我希望它可以帮助某人。

请注意，文件上传在定义上是不安全的！我曾经和 Helmut 谈过这件事，很难防止坏东西。此脚本中有一些验证，但还不够。在我的情况下，前端用户“有点信任”，前端登录由管理员提供。
