3 Different Validation Methods - Why?
Hey there,

i took the Demo 3 (Something with Flight/Travel Registration) as Template for my own Form.
I rewrote the code using some of the code already present.
This is where i discovered that you are using three types/methods of Validation.

1. Client-Side Validation with JS and rsv.js.
<script type="text/javascript" src="rsv.js"></script>

  <script type="text/javascript">
  var rules = []

  // Attendee / work information
  rules.push("required,name,Please fill in your name.");


2. Server Side Validation with PHP using validate_fields();
$rules = array();
  $rules[] = "required,name,Please fill in your name.";
  $errors = validate_fields($_POST, $rules);

3. Server Side Validation with PHP filling the Error Array by yourself.
if (isset($_POST) && !empty($_POST))
        $errors[] = "Please fill in your name.";

Is there an advantage in using two or all three Methods at the same time? Or should i choose only one method?
Is the second Method more reliable because Client-Side is JavaScript?
Is the third for checking more complex conditions like the following?
if(!empty($_POST['a']) && empty($_POST['b']))
        $errors[] = "Please fill in B when providing A.";

Thanks in advance for replies, asgaroth
