Change 'Special Instructions' to a required field + Add placeholder text

Topic summary

Goal: Make the cart’s “Special Instructions” (order note) act like a required field and add guidance text.

Key points and updates:

  • Initial ask: Require “Special Instructions” and add placeholder text. Clarified need to add an additional text prompt in the cart for “van registration #”.
  • Guidance given: Enable the cart note via theme customization (screenshots shared). A tool was suggested to add custom fields on product pages (not cart), with offer to help implement.
  • Clarification: The requester wants a new text field/title in the cart, above “Special Order Instructions,” reading “Van Registration or Zone Build Number (required).”
  • Limitation discovered: Cart note fields cannot be made truly required; checkout proceeds even if empty. Suggested alternative: add a required text field on the product page (before Add to Cart) to enforce input.
  • Current stance from requester: Accepts that the cart field can’t be enforced; still wants the new cart text field added with “(required)” in the label to encourage completion.

Status and next steps:

  • No implementation yet; theme details requested to proceed. Decision pending on adding the labeled cart field vs. enforcing a required product-page field.
  • Screenshots are central to enabling the cart note in theme settings.

i want to add another title and short answer under ‘order note’ that says ‘van registration #’.

Yeah sure what theme are you using again? I can help create the fields according to that.

Suggestion:

But you see the order note are not compulsary for checkout user may ignore it.

You can add text field to product page asking “van registration #” and make it required so user will have to fill this.

We would like to add a text field in the cart, above the ‘special order instructions’ which says ‘Van Registration or Zone Build Number (required)’. Could you please advise. Thanks

Sorry I just checked but we can’t add required filed on cart note, I tried adding required field on cart note but even it was empty the checkout button worked.

Can we just add required field just above the Add to Cart so it will be visible to user?

Sorry you may have misunderstood. Please add a field which the title says ‘Van Registration or Zone Build Number (required)’ above the ‘special order instructions’ in cart. I know you can’t make it a required field, but by adding the work required in the title people will still be under the assumption it is required.
