  Validating a multi page sessions form with php

  Posted by Travis Barr on January 1, 2011 at 7:30 pm

  I have tried every way but the correct way to figure this one out. I have a multi page sessions form and I have an inline validation script. I am trying to figure out how to combine the two. For the sake of saving space I will not post all my mistakes, but bellow are the two scripts. Any advice or pointers would be welcomed, thanks.

  Multi form script:

  <?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)
  {

  ?>

  The validation script:
  
<?php

  if ($_SERVER['REQUEST_METHOD'] == 'GET')
  {

  //just display the form if the request is GET
  display_form(array());
  }
  else
  {
  //the request is a POST so validate the form
  $errors = validate_form();
  if (count($errors))
  {
  //if there were any errors, redisplay the form with the errors
  display_form($errors);
  }
  else
  {
  //the form data was valid so print a congratulations message
  print 'the form was submitted.';
  }
  }

  function display_form($errors)
  {
  //set up defaults
  $defaults['first_name'] = isset($_POST['first_name']) ? htmlentities($_POST['first_name']) : '';

  ?>
