My company just bought out another company and I have to change some links on their site to point to our site. However, this site doesn't have a static footer or header (as in, each link is recreated on each HTML page). So instead of changing the necessary files (30+), is there any other way to do a sweeping change?
While there are several methods, the one that I would recommend would be to use a server side include file.
My recommendation would be to follow these steps, approximately:
<?php require_once 'header.php'; ?>
While this may take longer initially, the very first time you have to make any updates it will pay off.
Lastly, there are ways - if necessary - to (utilizing PHP) make the current nav item have an active class, etc. That's a bit of a stretch for this answer, but this answer may get you going in the right direction.
