Redirect page with error message

Good afternoon, I have a question Is this command correct?

http://localhost/site/index.php#contato?info=Email%20Vazio

  

index.php # contact? info = Email% 20Value

This is the function that sends the command but the page is at the top and the message no longer appears on the form.

private function setNome($nome){
    if(!empty($nome)){
    $validar = new Validar($nome);
    $this->nome = $validar->getValidado();
    }else{
    $this->setError("Nome Vazio");
    return print "<script language='JavaScript'>location.href='"
    . "index.php#contato?info={$this->getError()}'</script>";
    exit();
    }

If I remove the #contato , it works but I'd like it to go straight to the form so that the user does not have to scroll down the page again at every typo
