I've been trying to build a category filter. I managed to make my buttons respond with categories but the returned entries on the page stay the same. So when I click one of the links "/?category=koop" gets added to the URL, but my entries don't respond upon that URL. I do have added the categories in the CP and assigned them to my entries.
Here is the code of my filters:
{% if craft.request.getParam('offerCategory') is not null %}
{% set offerCategory = craft.categories.slug(craft.request.getParam('offerCategory')) %}
{% set offers = craft.entries.section('offers').relatedTo(offerCategory).find() %}
{% else %}
{% set offers = craft.entries.section('offers').find() %}
{% endif %}
And my button list
{% for offerCategory in craft.categories.group('offerTypes').find() %}
<li>
<a class="mart-button" href="{{craft.request.url}}/?category={{ offerCategory.slug }}">{{ offerCategory.title }}</a>
</li>
{% endfor %}
I'm quite new to Craft. One of the resources I'm using to build this is: http://craftcookbook.net/recipes/197.
If anyone knows what I'm overseeing, thanks in advance.
