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。
我已经添加了以下配置。
配置/TCA/覆盖/tx_cart_domain_model_order_item.PHP
<?PHP
$temporaryColumns = [
'images' => [
'exclude' => 0,'label' => 'Upload Image','config' => \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::getFileFieldTCAConfig('images',[
'appearance' => [
'createNewRelationLinkTitle' => 'LLL:EXT:cms/locallang_ttc.xlf:images.addFileReference'
],'maxitems' => 1,// custom configuration for displaying fields in the overlay/reference table
// to use the imageoverlayPalette instead of the basicoverlayPalette
'foreign_match_fields' => [
'fieldname' => 'images','tablenames' => 'tx_cart_domain_model_order_item','table_local' => 'sys_file',],'foreign_types' => [
'0' => [
'showitem' => '
--palette--;LLL:EXT:lang/locallang_tca.xlf:sys_file_reference.imageoverlayPalette;imageoverlayPalette,--palette--;;filePalette'
],\TYPO3\CMS\Core\Resource\File::FILETYPE_TEXT => [
'showitem' => '

]
]
],$GLOBALS['TYPO3_CONF_VARS']['GFX']['imagefile_ext'])
],];
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTCAcolumns(
'tx_cart_domain_model_order_item',$temporaryColumns
);
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addToAllTCAtypes(
'tx_cart_domain_model_order_item','images','','after:comment'
);
ext_localconf.PHP
$dispatcher = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Extbase\SignalSlot\dispatcher::class);
$dispatcher->connect(
\Extcode\Cart\Utility\OrderUtility::class,'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 [
\Extcode\Cart\Domain\Model\Order\Item::class => [
'tableName' => 'tx_cart_domain_model_order_item'
],];
模型：类/域/模型/Order/Item.PHP
<?PHP
namespace vendor\myext\Domain\Model\Order;

class Item extends \Extcode\Cart\Domain\Model\Order\Item
{
/**
* images
*
* @var \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\TYPO3\CMS\Extbase\Domain\Model\FileReference>
*/
protected $images = NULL;
/**

*/
public function __construct() {
//Do not remove the next line: It would break the functionality
$this->initStorageObjects();
}
/**
* Initializes all ObjectStorage properties
* Do not modify this method!
* It will be rewritten on each save in the extension builder
* You may modify the constructor of this class instead
*
* @return void
*/
protected function initStorageObjects() {
$this->images = new \TYPO3\CMS\Extbase\Persistence\ObjectStorage();
}
/**
* Removes a FileReference
*
* @param \TYPO3\CMS\Extbase\Domain\Model\FileReference $imagetoRemove The FileReference to be removed
* @return void
*/
public function removeImage(\TYPO3\CMS\Extbase\Domain\Model\FileReference $imagetoRemove) {
$this->images->detach($imagetoRemove);
}
/**
* Returns the images
*
* @return \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\TYPO3\CMS\Extbase\Domain\Model\FileReference> $images
*/
public function getimages() {
return $this->images;
}
/**
* Sets the images
*
* @param \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\TYPO3\CMS\Extbase\Domain\Model\FileReference> $images
* @return void
*/
public function setimages(\TYPO3\CMS\Extbase\Persistence\ObjectStorage $images) {
$this->images = $images;
}
}
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;
}
}
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。
解决方法
有点晚了，但几年前的一个 9.5 项目我创建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。

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。
