Post Link to a Page

Hi guys, I have a pl/sql application that I am developing. I couple it with a PHP application
tha allows for the user to upload a file to the webserver. What I want to do is then take the path
from the uploaded file and post it to the pl/sql page.

I know how to do this with text fields, but don't want to place the link in a text field. My page is
devised of many separate tables for a dashboard format.

I know how to pass back values from one page to another, I just don't know how to secure a placeholder
so that the code posts the link to the appropriate spot on the page.

Thanks!
