You can share your script??
I'm relatively new to creating Adobe Forms but I'm looking to do exactly what you have set up, submitting the results to php which sends the results to a database. I don't like the responses being sent to a pdf response file then every so often you have to export to csv then import the results into a database....too tedious. Can you perhaps provide the code that goes behind the submit button and maybe the code that you use on the php/server side? Again, relatively new to this and don't know where to begin but if I can look at the code behind this it would make things a lot easier.
I'm very interested in this code too. Can you please share it with us?
