How can I extract values from a selected metaObject list?

[Darius90]

Hi everyone,

it looks so simple thing but can't get the values of the metaobject when it is selected "List of values".

I thought I have to once again iterate it. But it returns nothing. It is really frustrating debugging when not getting any errors. 

{% assign myfields = product.metafields.sp_custom.size_chart_metaobjects.value %}

{{ myfields }}
// it return MetaobjectDrop

{% for m in myfields.sizes %}  
    {{m.value}} //nothing works
    {{m[0].value}} //nothing works
{% endfor %}

or

{% for m in myfields %}  
  {% for s in myfields.sizes %} 
    {{ s }} //nothing works
    {{ s.value }} //nothing works
    {{ s[0].value }} //nothing works
  {% endfor %}
{% endfor %}

Hi Darius,

Add this to your liquid and send here what you get in your browser console:

<script>{{ myfields | json }}</script>

I have the same issue. Really annoying. You get: "error: json not allowed for this object"
It's an array. ["S", "M", "L"]

@josu24 what about the result of this one?

<script>{{ myfields | json }}</script>

I am having this same issue... can't figure out how to access the list of values correctly. ANy progress?

Give more information on what are you trying to access in your code send that part of your code here!

I did debugging metaobject when it is selected "List of values" below.

It should shows key and value set for size_chart_metaobjects metafield.

product.metafields.sp_custom.size_chart_metaobjects.value | json

So, product's meta fields value can be referred by this code.

product.metafields.sp_custom.size_chart_metaobjects.value['size_chart_metaobjects']

Hope it works for everyone who has been stuck on this issue.

And also, a quick addition;

If you'd like to access a spesific type in this: 

product.metafields.sp_custom.size_chart_metaobjects.value['size_chart_metaobjects']

you need to use a forloop to access it's spesific values like the following:

{% for prod in product.metafields.sp_custom.size_chart_metaobjects.value
%}
{{ prod.title }}
{% endfor %}​

Thanks a lot, that's also helped me, even the Shopify chatbot also gave the error code, it took my full night.
