Not sure if this is the forum area for this, but I'll give it a try. I have a drop-down list that generates the section option depending on what user chooses. I would like that option chosen, to open the PDF from the submit button. Can't figure out how to do this. Is this even possible without having a database created? It's only going to be a couple of pdfs. Thanks for any help!
I have 2 folders on my server. Each house the pdfs.
Here is the php code:
