Help with a query, and return result on the same page.

I am trying to query a database, and return the results on the same page. I have a form to enter the item that I want to query. I would like to have a table below, so that the results would be displayed. right now I'm just using a small database to get the things working. I can query a database and display the data when the page is loading, but not able to do a query and display only the desired data from a form. Most of the database work that I would need to do right now is on this order. Have a page setup where the users would come in and select or enter the query criteria, and the data will then be pulled and displayed from the database. I am connected to MySql, and can connect to ODBC... I have been going through tutorials and also using DreamWeaver UltraDev with PHP extensions...but have not found an example like this... Thanks Martin
