Show product Tags in product page

[joanlafulla2]

Hi. I'm trying to show the product tags in product.tpl.

<ul class="my_tags">
	{foreach from=Tag::getProductTags(Tools::getValue('id_product')) key=k item=v}
  		{foreach from=$v key=lang_id item=value}
			<li><a href="{$link->getPageLink('search', true, NULL, "tag={$value|urlencode}")}">{$value|escape:html:'UTF-8'}</a></li>
		{/foreach}
	{/foreach}
</ul>

The problem is that every tag is showed two times in the different two languages.
I would like to filter the tags by language, but the code doesn't work.

{assign var=tags value=Tag::getProductTags($product->id)}
{assign var=id_lang value=Context::getContext()->language->id}
{assign var=product_tags value=$tags[$id_lang] }

<ul>
{foreach from=$product_tags key=k item=v}
{foreach from=$v item=value}
<li><a href=”{$link->getPageLink(‘search’, true, NULL, “tag={$value|urlencode}”)}”>{$value|escape:html:’UTF-8′}</a></li>
{/foreach}
{/foreach}
</ul>
