"Little" question on form_validation - El Forum - 11-21-2008

[eluser]hugle[/eluser]
Hello.

I currently whore a little extention to form_validation
I called it : if_exists
example below:

Code:
$this->form_validation->set_rules('iam', 'I am', 'if_exists[iam.id]');

I wonder if I can pass variable from $_POST request into this extention?

for example I would like to pass the value of $_POST['country'] to the:

Code:
$this->form_validation->set_rules('iam', 'I am', 'if_exists[iam.id]');

I found this one working:

Code:
$country = $_POST['country'];

$this->form_validation->set_rules('iam', 'I am', "if_exists[iam.id.$country]");

Maybe there is more clever way to do this ?

Using some "native" functions of form validator or something similar?

Thank you !
