How to display individual values from 'Accept list of values' in metafields?

Technical Q&A
1

I’m trying to take advantage of the “Accept list of values” option in the ‘Single line text’ metafield option.

If I’m understanding how it works, I should be able to access those individual values, and display them on the page.

So far all I can do is just print the values in brackets:

{{ product.metafields.my_fields.list1 }}

[“test1”,“test2”,“test3”]

I tried {{ product.metafields.my_fields.list1[1] }} but that didn’t do anything.

Any help would be appreciated.
Thanks, Nick C.

Oh do i just need to add “value”?

{{ product.metafields.my_fields.list1.value[1] }}

Did you ever figure this out? I am running into issues where this is not displaying a list where I place the metafield.

For my purposes {{ product.metafields.my_fields.list1.value[1] }} this worked.

I haven’t looked into how to make it do a loop, where it will automatically display all the items in a list, as I don’t necessarily need it to at the moment. So I’m just doing it manually.

fish, blue, apple, hat

{{ product.metafields.my_fields.list1.value[0] }}

{{ product.metafields.my_fields.list1.value[1] }}

{{ product.metafields.my_fields.list1.value[2] }}

{{ product.metafields.my_fields.list1.value[3] }}

fish

blue

apple

hat

You can simply iterate over the “value” to expose each list item:

{% for related_product in product.metafields.related.products.value %}
  ...
{% endfor %}

Or:

{% assign related_products = product.metafields.related.products.value %}
{% for related_product in related_products %}
  ....
{% endfor %}

If we set this up on products and each product might have a different number of list items, what happens if we reference a non existent value? Would it be somehow possible somehow to code an if-then to fallback to value[1] in those situations if the called list reference value doesn’t exist?

For example: {{ product.metafields.my_fields.list1.value[5] }} is used but the product’s metafield list only has 3 items… so show {{product.metafields.my_fields.list1.value[1] }} instead

yes,

{% if product.metafields.my_fields.list1.value[5] == blank %}

this will show if 5 IS empty

{% endif %}

{% if product.metafields.my_fields.list1.value[5] != blank %}

this will show if 5 is NOT empty

{% endif %}

I think you can also just use {%- else -%} but I like using 2 separate statements, if necessary.
