I know that tokens (token module) can be used to fill tokens.
But for my articles (pages like node), how can I use tokens to get my site name, etc. could be replaced automatically?
Check Token Filter Module . This will allow you to use markers in the body field of the node.
On the module page:
, , [ ] .. , . Token .
. README.txt
Drupal 7
Token Filter " ", . HTML.
node [site: name], , .
, Help- > Token, , (/admin/help/token).
