How can I check for attachments?

[Former Community Member]

I have check boxes adding attachments to a form.  On clicking a Submit button, I need a script to check for an attachment if the corresponding check box is selected.  Any suggestions?

Thanks!

Hi,

you can check the number of attachments the following way:

if (event.target.dataObjects) {
    // When there are attachments
     var o = event.target.dataObjects.length;
    xfa.host.messageBox("There " + (o > 1 ? "are " : "is ") + o + (o > 1 ? " files" : " file") + " attached.");
} else {
  // When there are no attachments
  xfa.host.messageBox("There are no files attached");
}

Hello,

I have a checkbox that should be checked if there are files attached.  I have the following script in the layout:ready event of the checkbox field, but it doesn't work.  I have tried putting form1.execCalculate() in different areas of the form, but nothing seems to work.  The only time the box gets checked is when drop-downs in the form are used.  Any help would be appreciated.

if (event.target.dataObjects) {
  this.rawValue = "1";
}
else {
  this.rawValue = "0";
}
