MiniVend uses HTML forms for order, search, and control operations. Order operations possibly include ordering an item, selecting item size or other attributes, and reading user information for payment and shipment. Search operations may also be triggered by a form. In addition, the user can control certain aspects of the session, such as order security, frames presentation, and background display via a control form.
MiniVend as of 3.12 supports file upload with the multipart/form-data
type. The file is placed in memory and discarded if not accessed with the [value-extended name=filevar file_contents=1] tag or written with [value-extended name=filevar outfile=your_file_name]. See
Extended Value Access and File Upload.
