Form Validation (Twice)

[eluser]macigniter[/eluser]
I am running the validation twice in one of my controllers because I want to validate one rule before all others. This way I don't get all of the error message of the second validation if the first one didn't even pass.

I am using this approach:

Code:

// set first validation rule
$this->form_validation->set_rules(...);

// only if first rule passed, check for other rules            
if ($this->form_validation->run() == TRUE)
{
    $this->form_validation->set_rules(...);
    $this->form_validation->set_rules(...);
}

// if first rule didn't pass the form only displays an error for the first rule
if ($this->form_validation->run() == FALSE)
{
    // then re-populate form
}

Is that something you anticipated?
