Question

我注意到在PrestaShop 1.7中你可以标记产品。是否可以通过编程方式按标签搜索产品？

例如，如果我想找到包含任何[＆＃39; madcow，crazydog，happyant＆＃39;]标签的产品，我该如何处理？

$this->context->getProducts('tag', ['madcow, crazydog, happyant']) ?

或者

Product::getByAttribute('tag', ['madcow, crazydog, happyant'])

或类似的？

任何非常感谢的帮助

Answer 1

您可以通过执行以下操作获取活动产品（ID和名称）foreach标记：

$tag = new Tag(null, "tag", $idlang);
$products = $tag->getProducts();

标签构造器也是如此，你的代码可能是：

$context = \Context::getContext();
$idlang = $context->language->id;

$tags = ['madcow', 'crazydog', 'happyant'];
$products = [];
foreach($tags as $t){
    $tag = new Tag(null, $t, $idlang);
    if($tag != null){
        $tag_products = $tag->getProducts();
        foreach($tag_products as $tg)
            $products[$tg['id_product']] = $tg['name'];
    }
}

Answer 2

您可以使用此代码段：

$array_tags = implode(',',['one','two','three']);

$id_lang = $this->context->language->id;

$products = Db::getInstance()->executeS('
    SELECT pl.id_product
    FROM `'._DB_PREFIX_.'product` p
    LEFT JOIN `'._DB_PREFIX_.'product_lang` pl ON p.id_product = pl.id_product'.Shop::addSqlRestrictionOnLang('pl').'
    '.Shop::addSqlAssociation('product', 'p').'
    WHERE pl.id_lang = '.(int) $id_lang.'
    AND product_shop.active = 1 
    AND p.id_product IN (SELECT pt.id_product FROM `'._DB_PREFIX_.'product_tag` pt WHERE pt.name IN ('.pSQL($array_tags).'))
    ORDER BY pl.name');
