Hi, I've started getting this error "Required parameter missing or invalid: items" when adding to cart

My theme is debut, my site is littletingles.com 

My product-template.liquid code is :

<div class="product-template__container page-width"

  data-section-id="{{ section.id }}"
  data-section-type="product"
  data-enable-history-state="true"
  data-ajax-enabled="{{ settings.enable_ajax }}"

This is an accepted solution.

Figured it out myself. If anyone ever has this problem. I had to add:

value="{{ variant.id }}">	
                    {{ variant.title }}

too line 162 so that the code would look like this:

 <option {% if variant == product.selected_or_first_available_variant %} selected="selected" {% endif %} {% assign featured_image = product.images.first | default: product.featured_image %} value="{{ variant.id }}">	
                    {{ variant.title }}
                  </option>

So glad I didn't pay someone just to find out that I need to add such a simple line of code to make it work.

Hello All,

 

I am facing the exact problem, my theme is Dawn. 

I tried to locate the right place in coding to add mentioned solution but it does not work. 

Anybody had the same problem with Dawn theme and found a solution? 

Please share the solution with all of us. 

I searched throughout Shopify but could not find the any useful information for dawn theme.

Just had the same issue kick in our site unexpectedly, looks like the issue was being cause by conflicting apps in the cart. Specifically the 'Volume Boost' App. 

 

We disabled this app and it seemed to have fixed the issue.

I'm just wondering if anyone found the fix for Dawn theme? I found this part of the code above, but it's all there.

 

He's current code for that section:

 

<noscript class="product-form__noscript-wrapper-{{ section.id }}">
<div class="product-form__input{% if product.has_only_default_variant %} hidden{% endif %}">
<label class="form__label" for="Variants-{{ section.id }}">{{ 'products.product.product_variants' | t }}</label>
<div class="select">
<select name="id" id="Variants-{{ section.id }}" class="select__select" form="{{ product_form_id }}">
{%- for variant in product.variants -%}
<option>
{% if variant == product.selected_or_first_available_variant %}selected="selected"{% endif %}
{% if variant.available == false %}disabled{% endif %}

value="{{ variant.id }}"

 

I've added, I've removed. Nothing seems to work. Let me know if anyone got a solution! Thanks in advance!

Hi,
Yes. But support and theme developers did not help. I started touse
the original theme file which ı uploaded it the first time. And it is
solved.

I have to say that their actions are so slow, I contacted them for 2 weeks, but no results.  I just add the code provided by ThomasKn, and it looks like working well, no errors. I'll keep testing.

I found and fixed the issue in Dawn theme.

 

The product id input is disabled by default line 426:

<input type="hidden" name="id" value="{{ product.selected_or_first_available_variant.id }}" disabled>

 Here is the fix:

<input type="hidden" name="id" value="{{ product.selected_or_first_available_variant.id }}" {% if product.selected_or_first_available_variant.available == false %}disabled{% endif %}>

thanks for sharing this method in free, I test on my theme-studio, and it works normally, the Shopify theme support didn't resolve this issue for me

Bonjour et merci beaucoup pour votre partage. Cela aurait pu m’aider mais depuis le thème a évolué en version et je n’ai que 328 pages ... je ne peux donc pas faire la modification.

you need to modify the code, according to  ThomasKn's method, this issue could be resolved, try again, maybe you need a developer if you could not understand code.

I am also having the same issue and it difficult to replicate when I get my theme developer to test it, when I add the code above to fix to my site , my site has other issues but I can at least make sales. Has anyone worked out what app may be causing this?

This is very frustrating.

Im using 'warehouse' theme

I just solved this problem:

 

In your theme.js file (assets folder), search for this code:

 

 

 document.dispatchEvent(new CustomEvent('theme:loading:start'));
        fetch("".concat(window.routes.cartChangeUrl, ".js"), {
          body: JSON.stringify({
            line: target.getAttribute('data-line'),
            quantity: parsedQuantity
          }),
          credentials: 'same-origin',
          method: 'POST',
          headers:
...

 

 

You need to check if the attribute line is being correctly sent (it has to be the number of the line in your cart, eg: 1, 2, 3...). 

Otherwise, change the attribute 'line' to 'id'. ID is a number like this: 1102325375907:6e543e26-4b83-40c8-8a23-11e.

The bug happens due to the inconsistency in the parameters. If you're sending a string, use 'id'. If you're sending the line number from your cart in your cart template, send 'line'. Also, maybe you'll need to change 'data-line' to 'data-line-id', depending on your html file.

 

For this, in your cart template file, check the funcion calls to confirm if you are sending the correct parameters. 

 

 

  <a href="{{ routes.cart_change_url }}?quantity=0&id={{ line_item.key }}" data-action="decrease-quantity" data-quantity="0" data-line-id="{{ line_item.key }}" class="line-item__quantity-remove link">{{ 'cart.items.remove' | t }}</a>

 

 

In short,

1. In my code, in the html I was sending the parameter 'data-line-id', and the JS was expecting 'data-line'. 

2. The JS file was expecting an integer as 'line' and I was sending a string as 'id'.

 

I hope it works for you guys.
