Why are my hidden empty meta fields showing again?

Hey 

iam using Meta fields to show ingredients, shipping details and how to use the product. But for some there are no such informations i looked for a solution to hide the empty meta fields in the frontend.  From a different Disscusion i found this code from this discussion Solved: How to hide blank metafields. - Shopify Community

 

<script>
const interval = setInterval(() => {
const blocks = document.querySelectorAll('.product__accordion.accordion.quick-add-hidden')
let allMetafieldsEmpty = true
for (let i = 0; i < blocks.length; i++) {
const block = blocks[i]
const blockApp = block.querySelector('.accordion__content')
if (blockApp) {
if (blockApp.childElementCount === 0) {
blockApp.parentElement.remove()
} else {
allMetafieldsEmpty = false
}
}
}
if (allMetafieldsEmpty) {
clearInterval(interval)
}
}, 100)
</script>


I implemented the code and it worked perfectly fine but one day later it didnt worked but i didnt changed anthing on the code.

do you have any idea why this is happening?

This is an accepted solution.

Sorry! please do 

{% if block.settings.content != "" %}
I've tested this locally so hopefully this should work for you 🙂

Can I ask why you're using javascript and not liquid? 
With liquid, you can wrap the html that you don't want to show if it's empty with an if statement - 
eg: 

{% if product.metafield.namespace.key != blank %}

<div> 

<h1> Here is a metafield bit</h1>

{{ product.metafield.namespace.key }}

</div>

{% endif %} 

 

If it's one block containing multiple metafield references and you want to remove it if there is nothing there, you can just use or in the if statement
eg 

{% if product.metafield.namespace.key != blank or product.metafield.namespace2.key2 != blank%}

<div> 

<h1> Here is a metafield bit</h1>

{{ product.metafield.namespace.key }}

{{ product.metafield.namespace2.key2 }}

</div>

{% endif %} 
This means it will only show if metafield 1 or metafield 2 (or both) exists.

Hi Mellowsilcbd, 
Could you show us in your liquid file where the metafields are referenced - ie the bit where you show the ingredients
Thanks 
Rhianna 🙂

Hi Mellowsilcbd, 
No, sorry I mean in the main-product.liquid (or similar, not sure what theme you're using) 🙂 
The bit on your product page where you reference the ingredients metafield 👍

Hi Rhianna,

do you mean on the "Frontend" of the Store what the Customer sees or in the Backend in the Section Products?

if it helps iam using the Dawn Theme

Hi Mellowsilcbd, 

I mean the code in shopify, not what the customer sees 🙂 

Not important right now, but this is all classed as 'Frontend' in web development haha 😄 

That does help, thank you. 
I just need to see in your code where it says {{ product.metafields. (and then what your metafield is called) }}

Ah okay - do you link to them in the theme editor then? 

(And not stupid at all!)

Ohh yes great, so in the liquid file if you search for 

{%- when 'collapsible_tab' -%}
I'm not sure exactly what yours will look like, as we use dawn but have made a lot of changes over time 

{%- when 'collapsible_tab' -%}
{% if block.settings.content != null %}
<div class="product__accordion accordion" {{ block.shopify_attributes }}>
more code  .. 
</div>
{% endif %}
{%- when 'reviews-io' -%} - This might not be your next block, but you'll just want the endif before the next 'when' 
 
You will want to add these bold bits in 🙂

Thank you very much so now it should look like this?image.png

Just move that {% endif %} down two lines, so it is above the {% when 'quantity_selector' %} 🙂

Thanks Mellowsilcbd! 
Yes sorry it took a little while and that my previous answer was a bit wrong! Technically the content is not "null" as it has the metafield reference i think, even if that metafield is empty. Glad it is working for you now 🙂 
Unless you change anything, this should continue to work - we use many if statements in our code reliably.
I wouldn't recommending using Javascript when it is possible to use liquid, it requires the content to load before removing it, so can require extra load time (small in this case) and some people have javascript disabled etc. When using liquid, it means the removal is done first 🙂

Hi @RhiRo ! Thanks for your help to Mellowsilcbd, it works for me too.

Question, how can I make this work too if the block has more than 1 metafields though? Appreciate your help!

Hi RhiRo.

 

I just want to ask if the multicolumn will be hide if the metafield is empty? I have 3 columns saying power, torque and weight saving. I just want to show those 3 columns if they have a metafield value

@Mellowsilcbd  where you this code added ?

where you create the meta filed ?

I will suggest to when you rener the metafiled that time you can check with 

{% if product.meta.  %} {% endif %}

The code is added in the theme.liquid section 

the meta field is created in products.
