My apologies for the confusion, I got part of this post mixed up with another that was working in ASP VB.
The idea is the same with php though, the server behavior is only designed to work with posted form elements, so dynamically created bindings are not usable with the multi insert without adjusting the function used.
The alternative is to add in update server behaviors, one for each record you inserted. In these updates you just add the file bindings that are missing from the inserted records.
