Pulling HTML into an HTML doc from external location
Forgive me if this is too elementary for this forum.
I post auction listings that consist of simple html. I may have as many as 300 active at one time. Within the html of the particular auction ad, there is a simple left hand navigation with text links to different categories in my online store mainly used for cross promotion. I need to be able to dynamically change the navigation in the existing 300 ads when the categories change.
I was thinking that I would have a text or html file on my server containing the navigation html so I would only need to change one file and have it dynamically pulled into the auction listing when it is opened.
This seems like it is a simple problem, but for a hack like me, I don't know where to start to find the answer. What do you suggest I do?
Thanks for any help.
