I'm new to Kohana. It is used this:
$this->request->param('id')
when should I use it - it means POST or GET?
When could I use it - how to pass parameters when they are $_POST or $_GET data?
Thanks!
Both POST and GET in fact are not true. For POST you will use:
$this->request->post();
For GET you will use:
$this->request->query();
That what you are asking:
$this->request->param('id')
is used if you want to get route id parameter.
