form text field: treat default value as empty

[eluser]SolarisDev[/eluser]
Hello Community,
I'm new to CodeIgniter and I have very simple problem. I have form field:

Code:

form_input("name", set_value("name", "New Category Name")

we have text field with value New Category name, now I neeed in validation to check that value is not empty but it shoul;d not be default value as well. In plain PHP I would do:

Code:

if($name == '' || $name == "New Category Name")
{
    return false;
}

How do I achieve that in CI, I have in controller function:

Code:

$this->form_validation->set_rules("name", "Category Name", "trim|required");

but that will just check if field is empty.

Thanks
