Liquid code for customer accounts with no tags

[KlaudiaZapiet]

Hey, need some help with coding a condition!

I'm trying to set a condition only for loyal customers with a specific tag. This works, however, if the customer doesn't have any tags, it doesn't seem to work.

I've tried the following:

{% for customer in customer.tags %}
{% if customer == 'test' %}
do something
{% endif %}
{% endfor %}

{% for customer in customer.tags %}
{% if customer.tags ==null %}
do something
{% endif %}
{% endfor %}

{% if customer.id == null %}
do something
{% endif %}

The first and third block works. However, the second one doesn't. If I'm logged in as a customer and my customer account has no tags, the action doesn't work. Am I doing something wrong?

Hello,

I'm surprised any of the above work. If you are just wanting to test if a customer has  a tag then something like

{% if customer.tags contains 'yourtaghere' %}

{% endif %}

Thanks Jordan, this works if the customer has a tag. However, I was trying to set up conditions for customers that have accounts, but don't have any tags. It worked with "customer.tags == blank"

Hey,

{% if customer.tags contains 'tag' %}

This should just return false if the customer has no tags - what error are you getting?

Hi @KlaudiaZapiet 

The first one is close

{% unless customer.tags == blank %}
    {% for tag in customer.tags %}
        {% if tag == 'test' %}
            do something
            {% break %}
        {% endif %}
    {% endfor %}
{% endunless %}

Amazing, this worked!
