hello guys

i have some guessing game code that works fine

i just need a few things adding to it that i dont know how to do if some body could please show me how.

its just a simple number game where the user has to keep guessing numbers between 1 and 10 till they get it right.

could somebody please how me how to add to the code so that.

- there is a counter that tells the user how many guesses they have had.

- the program stops at 7 guesses.

 

thanks guys 

 

my code is

 

 

 

if(isset($_POST['guess'])) {
    $guess = intval($_POST['guess']);
    $secret = intval($_POST['secret']);
 
    $output = "";
    
    if($guess == $secret)
    {
        $output .= "<h1>Correct!</h1>";
 
        $output .= "<a href='guessinggame.php'>Play again</a>";
    }
    elseif($guess < $secret)
    {
        $output .= "<h1>Your answer was too low. Please try again!";
    }
    else
    {
        $output .= "<h2>Your answer was too high. Please try again!</h2>";
    }
}
 
 
?>

Was bored, so I gave this a little go.

 

Try this:

 

<?PHP

  session_start();
  #session_destroy();
 
  //### Current file name
  $filename = basename($_SERVER['PHP_SELF']);
 
  //### If play is set, reset all values
  if(isset($_GET['play'])) {
    unset($_SESSION['number']);  
    unset($_SESSION['guesses']);
    unset($_SESSION['guessed']);
  }
 
  //### Start the output
  $output = '';
 
  //### Check if the form is posted
  if($_SERVER['REQUEST_METHOD'] == 'POST') {
    
    //### Set the number that was guessed
    $numberGuessed = isset($_POST['numberGuessed']) ? (int)$_POST['numberGuessed'] : FALSE ;
    
    //### If no number is guessed, display error
    if(empty($numberGuessed)) {
      $output .= 'Please enter a number to guess. <br>';
      
    //### Validation passed  
    } else {    
        
      //### Increment guesses
      $_SESSION['guesses']++;
        
      //### Check to make sure they have guesses available
      if($_SESSION['guesses'] <= 7) {
          
        //### check if they guessed the secret number
        if($numberGuessed == $_SESSION['number']) {
          $_SESSION['guessed'] = TRUE;
          
        //### check if the number is lower than the secret number
        } else if($_SESSION['number'] < $numberGuessed) {
          $output .= 'Bad luck! The number is lower. <br>';
        
        //### Else the number is higher
        } else {
          $output .= 'Bad luck! The number is higher. <br>';
        }
        
      }
    }
  }
 
  //### Set the secret number and amount of guesses
  $_SESSION['number']  = isset($_SESSION['number']) ? $_SESSION['number'] : mt_rand(1,10) ;
  $_SESSION['guesses'] = isset($_SESSION['guesses']) ? min($_SESSION['guesses'], 7) : 0 ;
 
  //### Debug purposes
  echo '<pre>';
  print_r($_SESSION);
  echo '</pre>';
 
  //### Check if the secret number has been guessed
  if(isset($_SESSION['guessed'])) {
    $output .= 'Well done! You guessed the number. <br>';
    $output .= '<a href="'.$filename.'?play=true">Play again?</a>';  
    
  //### Check if they have used all of their guesses
  } else if($_SESSION['guesses'] >= 7) {
    $output .= 'You used up all your guesses. <br>';
    $output .= 'The secret number was: '. $_SESSION['number'] .'. <br>';
    $output .= '<a href="'.$filename.'?play=true">Play again?</a>';
    
  //### If both checks passed, show form
  } else {
    $output .= '<form method="POST" action="'. $filename .'">
            Your Guess: <input type="text" name="numberGuessed">
            <input type="submit" value="Submit Guess">
          </form>';
  }
 
  echo $output;
?>

Ohh right, well you need to create a new session variable something like "$_SESSION['numbers_guessed']" and then add each guessed number that is wrong to that variable. Look into array for that.

 

Displaying amount of guesses I explained in my previous post, use the variable "$_SESSION['guesses']"

 

I did the hard work, now have a little try to see what you can do, and pop back with any questions :)
