I'm outputting all tags that are in use and then allowing the user to click these build up a query string to filter and display the results. It's all working fine.

Except, I'm having difficulty understanding what can I use to set an 'active' class on all the selected tags that are being added to the query string.

Setting 1 tag as active is simple enough, but when multiple are selected, I'm not so sure.

The URL looks like this: domain.com/learning/resources?tags=Video+Maths

Setting tags via getParam:

{% set tags = craft.request.getParam('tags') %}

Listing all tags in use like this:

{% set resourceTags = craft.entries.section('resources').limit(null) %}
{% for tag in craft.tags.relatedTo(resourceTags) %}

Outputting results like this:

{% craft.entries.section('resources').limit(craft.config.paginateLimit).search(tags) as entries %}`
  • I'm still having trouble with this. Is tags and search the wrong way to go about this?

The easiest way to do this is to create an array of tag ids for tags that should be active.

I would use a comma to separate multiple tags in your query string since the browser interprets a plus sign as a space. For example, if your tags were "New Videos" and "Maths" the url would look like this:


First, get the "tags" query parameter and make an array splitting each tag at a comma:

{% set tagsQuery = craft.app.request.getParam('tags')|split(',') %}

{# tagsQuery = ["New Videos","Maths"] #}

Search your tag group for matching titles and return an array of ids. This assumes you have a tag group with the handle "tags":

{% set activeTags = tagsQuery ? craft.tags.group('tags').title(tagsQuery).ids() : null %}

Then it's a simple matter of testing if the tag.id is in the activeTags array.

{% for tag in craft.tags.relatedTo(resourceTags) %}
  {{ tag.title }}

  {# Use a conditional #}
  {% if item.id in activeTags %}active{% endif %}

  {# or an output tag with a conditional #}
  {{ item.id in activeTags ? 'active' }}
{% endfor %}

Perhaps not the most elegant solution, but this works:

{% set queryTags = craft.request.getQuery('tags') %}

{% for tag in craft.tags.relatedTo(resourceTags) %}
     href="{% if tags == "" %}/learning/resources?tags={{ tag.title|kebab }}{% else %}/learning/resources?tags={{ tags|replace(' ', '+') }}+{{ tag.title|kebab }}{% endif %}"
     class="btn btn-default{% if tag.title|kebab in queryTags %} disabled{% endif %}"
   >{{ tag.title }}</a>
{% endfor %}

Adding disabled rather than active.
