Show tags for each entry

Question

I have one tag for each entry.

 - Entry1
     Tag1
 - Entry2
     Tag2

Now I want to show them in the title of each entry. But it doesn't work.

{% for entry in craft.entries.section('mainEntry').limit(4) %}
{% set tag = entry.mainEntryTag.first() %}
  <h2>{{ tag }} {{ entry.title }}</h2>
{% endfor %}

This results in displaying only the globally first tag:

- Entry1
     Tag1
- Entry2
     Tag1

If I just write: {% set tag = entry.projektart %} I get the error: Object of class Craft\ElementCriteriaModel could not be converted to string

How can I get to current entry tag?

Answer 1

You're very close. Change "set tag" to "set tags" so you have:

{% set tags = entry.projektart %}

And then loop through the tags:

{% for tag in tags %}
    {{ tag }}
{% else %}
    No tags found
{% endfor %}

You could also simplify this and instead of setting the "tags" variable you could write the following:

{% for tag in entry.projektart %}
