Challenge Task 1 of 2

Check that each of the required session variables are not set before attempting to write the story. If the session variables are not set, redirect to play.php with the p parameter set to the first missing session variable.

story.php
<?php
{
if (isset($_SESSION['word'][1])
 && isset($_SESSION['word'][2])
 && isset($_SESSION['word'][3])
 && isset($_SESSION['word'][4])
 && isset($_SESSION['word'][5]))

session_start();
$word1 = htmlspecialchars($_SESSION['word'][1]);
$word2 = htmlspecialchars($_SESSION['word'][2]);
$word3 = htmlspecialchars($_SESSION['word'][3]);
$word4 = htmlspecialchars($_SESSION['word'][4]);
$word5 = htmlspecialchars($_SESSION['word'][5]);

include 'inc/header.php';

echo '<h1>My Treehouse Story</h1>';

echo '<p>There once was a(n) ' . $word1;
echo ' programmer named ' . $word2; 
echo '. </p>';
echo '<p>This ' .  $word3; 
echo ' programmer used Treehouse to learn to ' . $word4;
echo ' the ' . $word5 . '.</p>';

echo ' <a class="btn btn-default btn-lg" href="#" role="button">Save Story</a>';
echo ' <a class="btn btn-default btn-lg" href="play.php" role="button">Play Again</a>';
echo ' <a class="btn btn-default btn-lg" href="index.php" role="button">Other Stories</a>';

  exit;
}else if(!isset($_SESSION['word'][3])){
 header('Location: play.php?p=3');
  exit;
}else if(!isset($_SESSION['word'][4])){
 header('Location: play.php?p=4');
  exit;
}else if(!isset($_SESSION['word'][5])){
 header('Location: play.php?p=5');
  exit;
}
$word1 = htmlspecialchars($_SESSION['word'][1]);
$word2 = htmlspecialchars($_SESSION['word'][2]);
$word3 = htmlspecialchars($_SESSION['word'][3]);
$word4 = htmlspecialchars($_SESSION['word'][4]);
$word5 = htmlspecialchars($_SESSION['word'][5]);
