Question about a Sidebar

I have a website with a sidebar that containz links to all tha pagez with videoz you can download. Tha thing iz, that I everytime I put up a new video, I have to go and change each page of my site so that tha link to tha new page iz on tha sidebar. I don't know much about HTML, but I'm tryna figure out a way to make it so I can have maybe somethin like a file called 'sidebar.html', and place that in my pagez somehow, and then I will only have to update tha sidebar file.

Please excuse my ignorance of HTML -- maybe my idea doezn't make sense.

haiya! HOw about using a frameset? hahah! But they told me that using frameset is not SE friendly. Well, i've been searching on how to fix my problem with my site for about 3days I think. haha!

Thank you. I will see if I can do that. And sorry, but what's SE?

SE is search engine. If your server supports PHP you can use PHP includes. So you will need to change the file extensions of all the pages you want the sidebar on to .php instead of .htm or .html or whatever it is. Now make a file sidebar.php and put your sidebar inside it. Then on all the other pages where you want the sidebar to go put <?php include("sidebar.php"); ?> then all you need to do is edit sidebar.php

Thank you both very much.
Johnathan -- I took your advice, and it works fine. And I made a PHP include for my menu too. Thank you.

Glad I could help .

Thanks for that Jonathan! I know what to do now. harhar!
