using input->post in model?

I'm trying to get values from the user input and use them in a where statement in the model, something like $this->db->where('partName, $this->input->post("partName")');

but I'm pretty sure I cant do that. Is there a way to use those input values in the model like I want to do though? Thanks

You can do that

PHP Code:

class Some_model extends CI_Model {
    public function __construct() {
        parent::__construct();
        // ...
    }
    public function do_something() {
        // ...
        $this->db->where('partName', $this->input->post("partName"));
        // ...
    }
}
