  How to validate a session() multi page form using php?

  Posted by Travis Barr on January 31, 2011 at 7:52 am

  I would like to make sure that there are no empty fields. I would like to add

  if (! strlen($_POST['first_name']))
  {
  print 'Please enter your first name.';
  }

  but I am not sure where to add it. any help would be appreciated.

  Thanks.

  <?php

  //Turn on sessions
  session_start();

  //Find what stage to use
  if (($_SERVER['REQUEST_METHOD'] == 'GET') || (!isset($_POST['stage'])))
  {
  $stage = 1;

  }
  else
  {
  $stage = (int) $_POST['stage'];
  }

  // Save any submitted data
  if ($stage > 1)
  {
  foreach ($_POST as $key => $value)
  {
  $_SESSION[$key] = $value;
  }
  }
  if ($stage == 1)
  {
  ?>
