如何在 fe varient 中使用新字段扩展 TYPO3 手推车产品?

How to extend TYPO3 cart product with new field in fe varient?

我正在尝试使用 fe 变体扩展一个新字段。我添加了以下代码:

ext_tables.sql

#
# Table structure for table 'tx_cartproducts_domain_model_product_fevariant'
#
CREATE TABLE tx_cartproducts_domain_model_product_fevariant (
    note text,
);

/myext/Configuration/TCA/Overrides/tx_cartproducts_domain_model_product_fevariant.php

<?php

defined('TYPO3_MODE') or die();

$temporaryColumns = [
    'note' => [
        'exclude' => 1,
        'label' => 'Note',
        'config' => [
            'type' => 'text',
            'eval' => 'trim',
        ],
    ],
];

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTCAcolumns(
    'tx_cartproducts_domain_model_product_fevariant',
    $temporaryColumns
);
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addToAllTCAtypes(
    'tx_cartproducts_domain_model_product_fevariant',
    'note',
    '',
    'after:title'
);

现在,后端按预期工作,在前端呈现值。我添加了如下模型:

myext/Classes/Domain/Model/Product/FeVariant.php

<?php

namespace Vendor\myext\Domain\Model\Product;

class FeVariant extends \Extcode\CartProducts\Domain\Model\Product\FeVariant
{

    /**
     * note
     *
     * @var string
     */
    protected $note = '';

    /**
     * Returns note
     *
     * @return string
     */
    public function getNote()
    {
        return $this->note;
    }

    /**
     * Sets note
     *
     * @param string $note
     */
    public function setNote($note)
    {
        $this->note = $note;
    }
}

并添加了 class 映射,如下所示

myext/Configuration/Extbase/Persistence/Classes.php

<?php
declare(strict_types=1);

return [
    \Vendor\myext\Domain\Model\Product\FeVariant::class => [
        'tableName' => 'tx_cartproducts_domain_model_product_fevariant',
    ],
];

我也找到了参考 here,但它也不适用于 fe_variant。

我认为你必须在 ext_localconf.php

中添加一些行
$GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects'][\Extcode\CartProducts\Domain\Model\Product\FeVariant::class] = [
    'className' => \Vendor\myext\Domain\Model\Product\FeVariant::class
];

\TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Extbase\Object\Container\Container::class)
    ->registerImplementation(
        \Extcode\CartProducts\Domain\Model\Product\FeVariant::class,
        \Vendor\myext\Domain\Model\Product\FeVariant::class
    );
