Forum PHP / Ad Code problems in sidebar

[محروم.كوم]

<div>I thought that the sidebar had an option to parse code in the sidebar. I have localized PHP code, javascript or iframe options. I tried the first two and neither will plugin to the sidebar without errors. Is there a special format for using ad code, php or javascript in the sidebar (well, any code for that matter?)

Note - I have a problem posting iframes in the sidebar and it throws my footer out of whack by doing so.

Javascript or php:

Parse error: syntax error, unexpected ' __DEFINE_LIKE_SHARE__
