Question

i was just make a simple script, but it don’t work.

function check_length($string, $min_length, $max_length) {
  $length = strlen($string);
  if(strlen($length) < $min_length || strlen($length) > $max_length)
  { 
    header("Location: /kontakty/blad");
  }
}

check_length($_POST["name"], "3", "45");
check_length($_POST["surname"], "3", "45");
check_length($_POST["group_id"], "1", "11");

When i send data to script, the function don’t check this.

You have a mistake. remove strlen on $length.

function check_length($string, $min_length, $max_length) {
      $length = strlen($string);

     if($length < $min_length || $length > $max_length)
     { 
      header("Location: /kontakty/blad");
     }
}
