PHP Hybrid - Data Integration

I am not familiar with PHP, but think I may be able to reverse engineer the solution that I need. I am using IWP for the major part of my web publishing, but I need reports. Started using PDF references in container fields, but this is getting to be a pain with the weekly update of the database.

I used the report selection of PHP Site Assistant to create the foundation. I need to limit access to data to the primary log in identifier, which I have done in the privledge set. How do I move that identifier, which is Get(AccountName), to the find screen/criteria to maintain record constrain in the PHP find screen (maintain client only having access to their records). The client will enter the remaining values for which they seek.
