Newbie Question -- One to many relationship / mySQL tables

I apologize in advance for what is probably a very newbie question, as I am still new to both mySQL and PHP but here goes: I have two tables in my database that have a one to many relationship. Table A is a list of scheduled classes, table B is the list of possible class titles and their descriptions. One field in table A establishes the relationship between the two tables: each record in table A has a unique ID from a record in table B. I think I should be able to write the SELECT query to display the complete data set (Date, Time, Title, Description) on the "Display Schedule" page, but I am not sure how to build my data entry form. I want the user to enter a date and time and then select the class (by title) from a drop-down. I need to write a SELECT query to generate the possible values of the drop down list, INSERT and UPDATE queries for when the user inserts or edits data. Can anyone suggest a good reference, tutorial, or example SQL / PHP to help me along? Thanks! Eric J Schwinder eric.AT.bergencomputing.DOT.com
