I have a table in a PHP form. I have two selectboxes on my form and one is tied to a database. Selectbox1 is data I hard-coded and Selectbox2 is linked to my database. I want Selectbox2 to only show records matching what was chosen in Selectbox1. From my understanding I need to do this through Javascript but I don't know how. Can I refer to Selectbox1 through Javascript even though it is in PHP code? How do I do this? As you can tell I am completely new to this so any and all help will be greatly appreciated. Thanks.
