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!

You can upload, preview, and submit attachments with HTML5 forms. By default, the attachment support is disabled. To enable the attachment support:

1- Create a custom profile with mutiselect string property mfAttachmentOptions.

2- In the custom profile, specify properties fileSizeLimit, multiSelect, and buttonText to configure options of the file attachment widget. As required, you can also specify more custom properties.

3- In the custom profile, use the following configurations:

  • multiSelect -> true or false (true by default)
  • fileSizeLimit -> value_in_mb (say 5) (2 MBs by default)
  • buttonText -> Button text for pop-up window ("Attach" by default)
  • accept -> file types to accept ("audio/, video/, image/, text/, .pdf" by default)

4- Use the metadata editor to select the custom profile that you have created above for HTML 5 forms.

5- Render your form template with custom profile and the attachments icon would appear on the forms toolbar.

6- Click the attachment icon, an attachment selection dialog box appears. Browse and select the attachment and click Attach.

When attachments are enabled, HTML5 form submits multipart data. The mutli-part submission data has two parts dataXml and attachments.

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.
