How to output the first tag only of each product

[joshua_lee]

Hi guys,

 

I've used Vekia's awesome code for tags on my shop for a few years now.  Now I would like to just pull (for output) the first tag of each product for SEO.

 

Is there anyone who would know how to do this?

 

This outputs all tags:

 

{foreach from=Tag::getProductTags(Tools::getValue('id_product')) key=k item=v}

  {foreach from=$v item=value}

    {$value|escape:html:'UTF-8'}

  {/foreach}

{/foreach}

 

I would just like to output the first one, if possible. Thanks!

Try this

{assign var='tags' value=Tag::getProductTags(Tools::getValue('id_product'))}
{foreach from=Tag::getProductTags(Tools::getValue('id_product')) key=k item=v}
 {foreach from=$v item=value name=value}
 {if $smarty.foreach.value.first}
 {$value|escape:html:'UTF-8'}        
 {/if}  {/foreach}
{/foreach}

Works perfect!

 

Edit - I just noticed the tags are stored in alphabetical order, anyway to store the values in the order they are added or some other way?

Ok, figured out a solution to my problem, just need to order by tag ID (ORDER BY pt.id_tag) in Tag.php, then make sure your 1st tags are higher up in the ID order.
