How to send custom input field data with an order?

Store Design

Topic summary

A store owner has added a custom Liquid input field to their product page to collect customer measurements (tissue box dimensions). They’ve implemented the field using {% form 'product', product %} with name="properties[Custom_Size]" to capture the data.

Current Issue:

  • Uncertain whether the input field data will automatically be included with order details at checkout
  • Seeking confirmation on proper implementation

Questions Raised:

  • Will the custom field data display on the checkout page and be included in completed order details?
  • Is there a better alternative method for capturing this custom data?

The post includes a product page link (rectangular fabric tissue box cover) but appears to have some text formatting issues. No responses or solutions have been provided yet.

Hi,

I’ve added a custom liquid input field on my product page, however I don’t know how to have the data from the input field sent to me as part of the order.

{% form ‘product’, product %}

For ‘Custom Size’:
Enter your tissue box height, width, and length measurements (to the nearest 1mm or 1/8")

{% endform %}

Is it possible to have the input field data displayed on the checkout page and included with the order details when the checkout is completed? Or is there another (better) way to capture custom data?

Thanks.
