  Parse error: syntax error, unexpected T_ELSE

  Posted by Travis Barr on January 1, 2011 at 1:24 am

  I have a script for a simple multi page form using sessions. I also have a simple script to add an inline error message on the same form. When I try to combine the two I am given a Parse error. It happens on:

  else if ($stage == 2)

  I think there is a lot here that I am messing up with, mostly, the placement of some functions. Any help is appreciated.

  Here is the combined code:
  <?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)
  {

  //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']) : '';

  ?>

  You have an “else if” right after the end of a function the “}” before the else if is ending the function… that’s why you have an error.

  function validate_form()
{
//start out with no errors
$errors = array();

  //name is required
if (! strlen($_POST['first_name']))
{
$errors['first_name'] = 'Enter your first name.';
}
return $errors;
}
else if ($stage == 2)
{

  Thank you, I moved around the function and it took care of the T_ELSE error, however were I put it just gave me more errors…oh boy. So I made a new thread. Thanks again for the help.
