问题描述
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.我愿意接受用户的图片.
I am trying to extend the model of Ext:cart. While someone orders a product from the cart page. I would like to accept images from users.
我已经添加了以下配置.
I have added the below configuration for the same.
配置/TCA/覆盖/tx_cart_domain_model_order_item.php
<?php

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.
Now, I have created a utility class to modify orderItem while placing an order. But, I am not getting an extended images field.
<?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;
}
}
谁能指导如何使用 FAL 图像扩展任何扩展并使用独立扩展进行扩展.
Can anyone guide how to extend any extension with FAL image and extend with standalone extension.
推荐答案
有点晚了，但几年前的一个 9.5 项目我制作了一个帮助类来将媒体附加到对象.这个仅限于图像、Youtube 和 Vimeo，但如果需要，扩展到其他媒体类型并不难.这并不理想，但它有效，我希望它可以帮助某人.
A bit late, but couple years back for a 9.5 project I made an helper class to attach media to objects. This one is limited to images, Youtube and Vimeo, but not very hard to extend to other media types if needed. It's not ideal but it's working, I hope it helps someone.

请注意，文件上传是不安全的！我曾经和 Helmut 谈过这个，很难防止坏事.此脚本中有一些验证，但还不够.就我而言，前端用户有点受信任"，管理员提供了前端登录信息.
Note that file upload is by definition unsafe! I talked once with Helmut about this, it's very hard to prevent bad stuf. There is some validation in this script but not enough. In my case the frontend users were 'kinda trusted' with frontend logins given by admins.
