AEM Forms (PDF Type) File Attachments

I am trying to implement file attachment to my AEM Form. The idea is to embed the attachment to the PDF; Upon submission of the PDF, the backend system will be able to extract the attached file from the PDF.

I can't seem to find any example on how I can go about doing it, which make me wonder is it a limitation. However, on adobe site below, it is actually stated "Support for file attachments" for all AEM form types.

Please advice! Thanks!

Solution

  • Below is the code for "Add Attachment" button.

    var oDoc = event.target;
var doccount = parseInt(colhead.attcount.rawValue);
colhead.attcount.rawValue = doccount + 1;
Trusted_ImportDataObject(oDoc, doccount);
var oAttachment = oDoc.getDataObject("attachment_" + doccount);
var DOsize = oAttachment.size;
var DOmimeType = oAttachment.MIMEType;
if (DOmimeType == null) DOmimeType = "reject";
if ((DOsize > 1100000) || (DOmimeType.indexOf("image/") != 0)) {
    xfa.host.messageBox("Attachemtns must be an image and smaller than 1 Megabyte");
    oDoc.removeDataObject("attachment_" + doccount);
} else {    
    var attachPath = oAttachment.path;
    AttachFileName.rawValue = attachPath;
    AttachMIMEType.rawValue = oAttachment.MIMEType;
    AttachHref.rawValue = oAttachment.name;
}

    Do note that Reader Extension is needed to enable file attachment. Else you will be getting this error:

    NotAllowedError: Security settings prevent access to this property or method.
