Attachment and Upload
Here is how you can use form upload features, FYI form upload is only available for starter and business users. All you need to add an upload field on the form just like another text field and add enctype="multipart/form-data" inside the form tag. For now, FormBold supports 5MB maximum upload (each file) with 30 days of data retention.
Form Code with Upload Example
<form action="https://formbold.com/s/FORM_ID" method="POST" enctype="multipart/form-data" > <label> Your email: <input type="email" name="email"> </label> <label> Your file: <input type="file" name="upload"> </label> <button type="submit">Send</button> </form>
