I have entries, which can have several categories. These categories are in different categorie groups.

Now if i show an entry page, i want to display i certain html block based on a specific category, the entry has or not.

i tried this, but its not working, i think i get the relatedTo thing wrong:

//i loop through all the categories in my group

{% for category in craft.categories.group('catGroup1') %}

//the i go to the section my entries are in and relate that to the categories i want to filter

{% set categoryListings = craft.entries({
  section: 'kelims',
  relatedTo: [
    { targetElement: category, field: 'filterThisCategory' }
}) %}

//if the entry has this category

{% if categoryListings|length %}

  display some html block

{% endif %}
{% endfor %}
  • I'm not sure I understand how you set the entry type in the kelims section. Could you tell me more about your filterThisCategory field? A screenshot of the field settings would help. I'm also unsure I understood correctly what you try to achieve. You just want to output some HTML if the entry you're currently viewing has a specific category, right?

  • My approach above was a wrong one. Regarding your last question, @nstCactus, yes, thats what i mean. I eventually fount the solution, with the help of these pages: craftcms.com/docs/3.x/categories-fields.html#templating, craftcms.com/docs/3.x/categories.html#querying-categories {% if entry.myFieldHandle.id('48, 49, 50, 51').exists() %} do this {% else %} do this {% endif %} myFieldHandle is the fieldHandle of the Category Group, where the categories i am searching for, are in.

  • @nstCactus, so your hint with the "exists()" was the right one, but i needed to add the ids.

craft.entries() returns an EntryQuery. You must then execute the query with one of those methods:

  • one()
  • all()
  • count()
  • exists()

In your case, I think .exists() is the best choice: {% if categoryListings.exists() %}

Edit: You may also have to execute your category query with {% for category in craft.categories().group('catGroup1').all() %}. See https://craftcms.com/docs/3.x/categories.html#querying-categories.

  • i tried your answers and hints, but no luck. maybe my approach with the craft.entries() is not the right one.
