Hello, I'm trying to add the below code I found to add MOQ but I'm not sure where to paste it in. My theme has quite a few instances of quantity. I'm certainly a noob to this so any help would be greatly appreciated!

 

<span class="input-amount">
<label for="quantity" class="hidden">{{ 'product.form.quantity' | t }}</label>
<input type="number" id="quantity" name="quantity"
{% if product.tags contains "MIN4" and current_variant.inventory_management == 'shopify' -%}
value="4" min="4"
{% else %}}
value="1"
{% endif %}
{% if current_variant.inventory_management == 'shopify' and current_variant.inventory_policy == 'deny' -%}
max="{{ current_variant.inventory_quantity }}"
{% endif %} required>
</span>

With technical and code you must make an effort to be specific.

You must remember not everyone knows what your seeing, avoid ambiguity.

Not everyone has your theme or access to it, provide accessible urls, or code samples(do not paste giant walls of code).

 

In vague general terms quantity customizations require changing the product form.

For some themes start from the product template trace the sections and snippets to find the  product form editing/replacing it's existing quantity behavior.

For other themes use the form attribute to link the new inputs to the main product form while disabling the old quantity.

 

If you just need this customization created then contact me by my email for services.

ALWAYS please provide context, examples: store url, theme name, post url(s) , or any further detail in ALL correspondence.

Thank you Paul. Below is a link to my website where I'm hoping I can add an MOQ. Sorry for the lack of clarity in my initial post. The goal is to add an MOQ to this product (and all other products).

That's studio , based on the dawn theme

https://github.com/Shopify/dawn/blob/main/sections/main-product.liquid#L255 

 

Ignore the quantity_rule stuff if you not using B2B features of a shopifyPlus plan.

 

You may need to remove novalidate from the main form in buy-buttons snippet

Would this be a better script to use? I'm still not understanding where it needs to go:

<p id="error-msg" style="display: none; color: red;">This product requires a quantity of 4 minimum.</p>

{% if product.tags contains "MIN4" %}
<script>
// Example to set a minimum on the input box
let qty = document.querySelector("#quantity");
qty.min = 4;

// I would add a backup, for example if you're using a select box or if the user's browser ignores the minimum attribute
document.addEventListener("click", (event) => {
  let qtySelected = document.querySelector.value;

  if (event.target.innerText.indexOf("Add to Cart") >= 0 && qtySelected < 4) {
    // Reveal an error message
    document.querySelector("#error-msg").display = block;
  }
});

</script>
{% endif %}

My assumption is that the code I need to edit is within this area, but I'm not sure where to paste/replace it. I've tried a few areas but none are having the expected result

 

{%- when 'quantity_selector' -%}
<div
id="Quantity-Form-{{ section.id }}"
class="product-form__input product-form__quantity{% if settings.inputs_shadow_vertical_offset != 0 and settings.inputs_shadow_vertical_offset < 0 %} product-form__quantity-top{% endif %}"
{{ block.shopify_attributes }}
>
{% comment %} TODO: enable theme-check once `item_count_for_variant` is accepted as valid filter {% endcomment %}
{% # theme-check-disable %}
{%- assign cart_qty = cart
| item_count_for_variant: product.selected_or_first_available_variant.id
-%}
{% # theme-check-enable %}
<label class="quantity__label form__label" for="Quantity-{{ section.id }}">
{{ 'products.product.quantity.label' | t }}
<span class="quantity__rules-cart{% if cart_qty == 0 %} hidden{% endif %}">
{%- render 'loading-spinner' -%}

<span
>(
{{- 'products.product.quantity.in_cart_html' | t: quantity: cart_qty -}}
)</span
>
</span>
</label>
<div class="price-per-item__container">
<quantity-input class="quantity" data-url="{{ product.url }}" data-section="{{ section.id }}">
<button class="quantity__button" name="minus" type="button">
<span class="visually-hidden">
{{- 'products.product.quantity.decrease' | t: product: product.title | escape -}}
</span>
{% render 'icon-minus' %}
</button>
<input
class="quantity__input"
type="number"

data-cart-quantity="{{ cart_qty }}"
data-min="{{ product.selected_or_first_available_variant.quantity_rule.min }}"
min="{{ product.selected_or_first_available_variant.quantity_rule.min }}"
{% if product.selected_or_first_available_variant.quantity_rule.max != null %}
data-max="{{ product.selected_or_first_available_variant.quantity_rule.max }}"
max="{{ product.selected_or_first_available_variant.quantity_rule.max }}"
{% endif %}
step="{{ product.selected_or_first_available_variant.quantity_rule.increment }}"
value="{{ product.selected_or_first_available_variant.quantity_rule.min }}"
form="{{ product_form_id }}"
>
<button class="quantity__button" name="plus" type="button">
<span class="visually-hidden">
