$_POST validation not FORM validation

[eluser]xtarx[/eluser]
I want to validate some POST data from an 'httpRequest' using the same functions of

form validation , i did some how copy functions form the 'form_validation' library ,but is there any better way to do it?

I want to do something like this

Code:

$this->form_validation->set_rules($_post['username'], 'Username', 'required');
$this->form_validation->set_rules($_post['password'], 'Password', 'required');
$this->form_validation->set_rules($_post['email'], 'Email', 'required');

Replace:

Code:

'$_post['username']'

with

Code:

'username'

And do the same for the other inputs you are going to check, hope it works.
