View Full Version : Postback with a Dreamweaver database connection

Hello everyone!
I have a page made by Dreamweaver that automatically retrieves information from a database and displays it in a table. What I need to do is incorporate a postback function so people can search the results on that page to further drill down what they want to see.

I have tried multiple time to accomplish this with no success. If anyone knows how to do this, it would be greatly appreciated. I am including the code at the bottom of this post. I know it's long, but it might help in getting a solution.

Thank you very much in advance.

Matt

can you explain a bit more:

"What I need to do is incorporate a postback function so people can search the results on that page to further "

Just to make sure we are in the same page.

post back how??? do you mean a search form??
