Only validation library

[eluser]Tominator[/eluser]
Hello there!

I've got one question: Is there any way how to make just validation library?

I mean: We use form validation library, which works like this:

Code:

$this->form_validation->set_rules('username', 'Username', 'required|min_length[5]|max_length[12]');
$this->form_validation->set_rules('password', 'Password', 'required|matches[passconf]');

I am looking for something, which will check local variables, like this:

Code:

$name = 'Peter';

$this->validation->set_rules('name', 'trim|required|min_length[5]|max_length[12]|xss_clean]');

if ($this->form_validation->run() == FALSE)
{
// we can continue here
}

Thanks for your help.

Tom.
