Problems with hreflang in products with combinations

[Alternativo]

Good day

We have carried out an SEO audit of the site and we are having problems with the products with combinations, as it indicates that they do not have self-referential hreflang tags.

Can you help us solve this?

Thank you

Hi,
Ensure that the getProductLink method is generating the full URL with the correct language code and combination parameters. If your products with combinations have unique URLs, each combination should have its own self-referential hreflang tag.

Now, Inside the product template, you need to ensure that the hreflang tags are properly generated for each language and each combination of the product. Here's how you can add a self-referential hreflang tag:
{foreach from=$languages item=language}
<link rel="alternate" hreflang="{$language.iso_code}" href="{$link->getProductLink($product.id_product, null, null, null, $language.id_lang)}" />
{/foreach}

Hi, thank you for your answer. Could you specify in which page we should put this code exactly?

Привет,
убедитесь, что метод getProductLink генерирует полный URL с правильным кодом языка и параметрами комбинации. Если ваши продукты с комбинациями имеют уникальные URL, каждая комбинация должна иметь свой собственный самореферентный тег hreflang.

Теперь внутри шаблона продукта вам нужно убедиться, что теги hreflang правильно генерируются для каждого языка и каждой комбинации продукта. Вот как можно добавить самореферентный тег hreflang:
{foreach from=$languages item=language}
<link rel="alternate" hreflang="{$language.iso_code}" href="{$link->getProductLink($product.id_product, null, null, null, $language.id_lang)}" />
{/foreach}

{$languages} is undefined when use it in the product.tpl

Sorry, Its seems you need to create the custom module to achieve the same. 

In the custom module, you need to register the displayHeaderHook and then you need to assign the $languages first from the hook like

$languages = Language::getLanguages(true, $this->context->shop->id);
$this->context->smarty->assign('languages' => $languages);

$this->context->smarty->assign('id_product' => Tools::getValue("id_product"));

Then you need to create the new template file & need to write the above code .

 

{foreach from=$languages item=language}
<link rel="alternate" hreflang="{$language.iso_code}" href="{$link->getProductLink($id_product, null, null, null, $language.id_lang)}" />
{/foreach}

The hreflangs URL are generates without combination paraments still using your code:

Page URL example: 

https://www.myshop.com/en/balance-line/111-3392-balance-line-balance-open-string-luxxa-lingerie.html

 

hreflangs: 

<link rel="alternate" hreflang="fr" href="https://www.myshop.com/fr/ligne-balance/111-ligne-balance-string-ouvert-balance-luxxa-lingerie.html">

<link rel="alternate" hreflang="en" href="https://www.myshop.com/en/balance-line/111-balance-line-balance-open-string-luxxa-lingerie.html">

The next modification of the getProductLink works: {$link->getProductLink($product.id_product, null, null, null, $language.id_lang, null, $product.id_product_attribute)}. I get the next hreflangs: <link rel="alternate" hreflang="fr" href="https://www.shop-example.fr/fr/ligne-borsalino/71-9232-ligne-borsalino-collier-epaulettes-borsalino-luxxa-lingerie.html#/color-black/harness_size-m">

But i added the "null" to the sixth parametr of the function getProductLink. The sixth parament is $idShop.

But the id of attributes didn't add and attributes names are not translated. Instead of "color-black/harness_size-m" at the end URL must be "11-couleur-noir/148-taille_de_harnais-m"
