在 bootstrap.php Shopware 5 中加载带有 id 的类别

Question

在我的 bootstrap.php 中，我尝试加载具有特殊 ID 的类别。不太好用。

    public function getCatFromDb($idCat){
    /** @var \Doctrine\DBAL\Connection $connection */
    $connection = $connection->get('dbal_connection');
    $sql = 'SELECT * FROM s_categories WHERE id=$idCat';
    $result = $connection->query($sql)->fetch();
    var_dump($result);

    return $result;
}

有人能找出错误吗？提前致谢！

Answer 1

$connection = $container->get('dbal_connection');
$sql = 'SELECT * FROM s_categories WHERE id="$idCat"';

Container代替第二个连接，$idCat在引号里。

Answer 2

public function getCatFromDb($idCat){
    /** @var \Doctrine\DBAL\Connection $connection */
    //$connection = Shopware()->Container()->get('dbal_connection');
    $connection = $connection->get('dbal_connection');
    $result = $connection->executeQuery(
        "SELECT * FROM s_categories WHERE id=?", [$idCat]
    )->fetchAll();
    var_dump($result);

    return $result;
}

Answer 3

您应该使用 ModelManager 来检索 Category。

/** @var ModelManager $modelManager */
$modelManager = Shopware()->Container()->get('models');
// you could use this, too
// $modelManager = $this->container->get('models');
/** @var Category $category */
$category = $modelManager->getRepository(Category::class)->find($id);
