Despite the fact that you mentioned you don't know PHP, I think you can still achieve this with little effort (and you don't even need to "convert" anything you already made). You
could achieve something similar to this in Dreamweaver by using templates, but if you wanted to make an update, you'd have to reupload ALL of the pages (this is kind of a pain). If you did this in PHP, you would only have to change and upload one file to make the change globally. It's really not difficult, and requires very little knowledge of PHP to implement. And once you set it up this way, making changes globally will be very easy.
Basically, you would rename all of your .HTML files to .PHP. (If, for some reason, this isn't possible for you, you can make a change to your .htaccess file to parse PHP in your HTML document). Then, you would create a file called
footer.php and include that file on all of your pages.
Example:Footer file:<span class="siteInfo">Copyright 2008, Your Company. All Rights Reserved.</span>
Wherever you want to include the footer, use this code:<? include('footer.php'); ?>
If you're using different paths for files, you would have to append that to the include. For example, if your
footer.php file is in the directory
/public_html/inc/, then you would use:
<? include('inc/footer.php'); ?>
That would be for all the pages in the root of your
/public_html/ directory.
If you're calling this include from a deeper folder, such as
/public_html/resources/resource.php, then you'd have to call it like this:
<? include('../inc/footer.php'); ?>
Any questions, just let us know!
