How to use File Upload Field in Optiontics

The File Upload field lets customers attach one or more files to a product before adding it to the cart — logos, photos, design proofs, documents. Uploaded files travel with the order, and you can optionally charge per file. You control which file types are allowed, the size limit, and how many files a customer may upload.

Use Cases #

• Custom-print products — customer uploads artwork or a logo.
• Personalized gifts — upload a photo to engrave or print.
• Print shops — submit a PDF or design file for a quote/order.
• Services that need a brief, spec sheet, or reference document.

How to Use #

1. Activate Optiontics Pro.
2. Open Optiontics → Add-ons and edit (or create) an add-on form.
3. Drag the File Upload block onto the canvas.
4. Select the block to open its settings on the right.
5. Set the label, upload text, allowed types, size, and count limits (below).
6. Save, assign the add-on to a product, and preview.
