Sponsorship packages

Enable Sponsorship packages in settings and tick Sponsorship package on a product. At checkout the sponsor sees a Sponsor details section:

• Company name (required), website, contact name, contact phone,
• Logo upload (JPG, PNG or WebP, max 10 MB, uploaded immediately via AJAX

  action seatpass_sponsor_logo_upload; SVG and PDF are rejected),

• Notes.

Rules: only one sponsorship package per order (adding a second replaces the first) and it is sold individually. Details are saved as order meta _seatpass_sponsor_*, shown in a Sponsorship box on the order screen, in a column of the orders list, in the admin new-order email, and the admin email subject is prefixed with the tier and company name.

Logos uploaded for carts that never became orders are deleted by a daily cron event (seatpass_sponsor_logo_cleanup) after 48 hours.
