Batch Processing with JavaScript using MySQL DB for Metadata

I've only discovered one post that seems to be close, but I cannot seem to get anything to work as of yet. Here's what I'm trying to accomplish:
-Batch process a directory of PDFs and update the title property using a database

The constraints I'm under:
-PDF manipulation must be done with Acrobat (PDFtk not acceptable)
-Using Acrobat 8 Pro
-MySQL database
-Portable batch script(aka, can't depend on ADBC on any given box)

From everything I've read, it seems that I should be able to process a formSubmit and return an FDF. However, I've been trying various tests using a php script to even simply a text file with a hardcoded FDF.

My question is if there is a better way to do this. Unfortunately I'm constrained to use Acrobat and this has plagued me for quite a while as I've gone through many iterations of attempts at getting the job done.

Now I'm just looking for some direction to see if I'm way off track. Thanks to anyone with some ideas.
