I am a beginner in PHP and WordPress. Ok let me just say I do not know realy much about programming. That why I try to use WordPress. It is simple and realy cool. But now I have problem with widgets. If I insert widget in my sidebar in sidebar.php nothing change. I supose this must be so. The problem is, that I do not wanna that this widget is visible on all my subpages. A friend told me that I have to do this with PHP. But how can I do this if I wanna to use exactly that kind of widget (calendar, simply image...)?
