This is not my solution.  100% credit goes to Max Morrow.  I just know I’m going to need this info again and wouldn’t want to lose it should Max take this blog post down. 

Here is his solution for not allowing a user to save an InfoPath form without first including at least one attachment.  I copying this excerpt word for word.  you can read the full post here Validating the Attachments Field

1.) Create a field in addition to the attachments field. In my case, I called the field I created Attachment Validation.

2.) Drop your field onto the form and remove the borders and background. Then set the default text to ‘Attachments:’

3.) Finally, lets apply some validation to this field. Right click the field on your form and select Rules > Manage Rules.

In my case, I needed to make sure there was at least one attachement. So, I counted the :attachmentURL instances and checked if there were more than 0. To do this, I used a custom expression:

Now with all of that complete you will have a separate field that validates the attachments field and if there are no attachments, the text in the left hand column will be surrounded in the standard red dashed border.

NOTE:

To get to the ‘:attachmentsURL’ field you need to create the validation make sure you go into Advanced View of the fields.
