Opening A Pdf From Dropdown Menu


Katemac

Recommended Posts

Sorry, I just realized I had it on a private server. It is just a index.php file. I have two separate folders with pdfs. I would like the user to make a choice in the drop down menu. Once they click the pdf, I would like it to open the pdf. I'm sure it is very simple, but I don't even know where to start... Right now I am not even really concerned with the drop down options, I just want the submit button to open the pdf.

 

Does this make sense? Thanks.
