include template
 

hey i was thinking of adding a sidebar to my forum and i wanted to have it in a own template like sidebar and i wonder how i can fix so i put $sidebar and the content in the template sidebar will be shown??

Hope you understand what i mean, its like $header and thoose.

Create a new plugin using something like global_start as the hook location. Then you need a code like:
Then in your template for example the footer template you can use the $sidebar variable to get your template.

i will need the whole plugin code because i don´t know how i do this.

Just add your code to the footer/header template then, its far easier way of doing it.

(If you want to try anyway, that should be all the code you need, I haven't tested it though but I'm pretty sure it works)

Why don't you just use one that is already created:
