How can I determine the size of a metafields list?

[henglw0621]

Hi, I have tried the following approach, but it doesn't work. I wonder how I can get the size of the metafields list.

{% if product.metafields.products.related.value.size > 0 %}
<p>Some related products here.</p>
{% else %}
<p>It is empty.</p>
{% endif %}

Where {% product.metafields.products.related.type %} is list.product_reference.

Hi @henglw0621 

Can you let us know where you want to display the metafields and the theme which you are using?

Hi @Tinytasks, thank you for reply.

I am using the following theme and display the metafields on the product page.

Hi @LitExtension, thank you for reply. 

I have checked the pagination reference you provided, but I don't know how I can apply it to my code. I would appreciate if you could give me some example code on how to apply pagination with the metafield list.

Hi @henglw0621,

Sorry for the confusion, you can use the following code:

{% if product.metafields.products.related.value != blank %}
<p>Some related products here.</p>
{% else %}
<p>It is empty.</p>
{% endif %}

Hope it helps!

Although this has been solved, here is a simpler solution:

Size of Metafield list = {{ product.metafields.products.related.value | size }}

{% liquid

assign related_products = product.metafields.products.related | split: ','

echo related_products | size

%}
