helpmehelpmehelpme Posted December 8, 2011 Share Posted December 8, 2011 I am supposed to create a guessing game in PHP that uses sessions to store a random number between 0 and 100, along with the number of guesses the user has attempted. Each time the user guesses wrong, display the number of times the user has guessed. And a give up link that displays the generated number for the current game. I have been working on this for a week and I can't figure it out. Any help would be appreciated. Here's my code thus far: game.php <?php session_start(); if (!isset($_SESSION["randNum"])) { $_SESSION["randNum"]=rand(1,100); } $randNum=intval($_SESSION["randNum"]); ?> <html> <body> <center><form action="game_check.php" method="POST"> Guess a number 1-100:<input type="text" name="userGuess"/> <input type="submit" value="Guess"/> </form></center> <center><form action="game.php"> <input type="submit" value="Restart"/> </form></center> </body> </html> game_check.php <?php session_start(); $_SESSION["randNum"] = $_POST["randNum"]; $userGuess=$_POST["userGuess"]; if (isset($randNum)) { if ($userGuess<$randNum) { echo "<center>You guessed too low!</center>"; } if ($userGuess>$randNum) { echo "<center>You guessed too high!</center>"; } if ($userGuess==$randNum) { echo "<center>Congratulations You're right!!!</center>"; unset($_SESSION["randNum"]); } } else { echo "Uh oh"; } ?> Link to comment https://forums.phpfreaks.com/topic/252785-guessing-game-php-with-sessions/ Share on other sites More sharing options...
scootstah Posted December 8, 2011 Share Posted December 8, 2011 Try this: game.php <?php session_start(); $_SESSION['randNum'] = isset($_SESSION['randNum']) ? $_SESSION['randNum'] : rand(1, 100); $_SESSION['guesses'] = isset($_SESSION['guesses']) ? $_SESSION['guesses'] : 0; ?> <html> <body> <center><form action="game_check.php" method="POST"> Guess a number 1-100:<input type="text" name="userGuess"/> <input type="submit" value="Guess"/> </form></center> <center><form action="game.php"> <input type="submit" value="Restart"/> </form></center> </body> </html> game_check.php <?php session_start(); $randNum = $_SESSION['randNum']; $userGuess=$_POST["userGuess"]; if (isset($randNum)) { if ($userGuess<$randNum) { echo "<center>You guessed too low!</center>"; $_SESSION['randNum']++; } if ($userGuess>$randNum) { echo "<center>You guessed too high!</center>"; $_SESSION['randNum']++; } if ($userGuess==$randNum) { echo "<center>Congratulations You're right!!!</center>"; unset($_SESSION["randNum"], $_SESSION['guesses']); } } else { echo "Uh oh"; } ?> Link to comment https://forums.phpfreaks.com/topic/252785-guessing-game-php-with-sessions/#findComment-1295988 Share on other sites More sharing options...
helpmehelpmehelpme Posted December 8, 2011 Author Share Posted December 8, 2011 awesome...thank you...it works, i see what I did wrong now.. any ideas about the counter that keeps track of the number of guesses. Im still stumped there too. thanks Link to comment https://forums.phpfreaks.com/topic/252785-guessing-game-php-with-sessions/#findComment-1295989 Share on other sites More sharing options...
scootstah Posted December 8, 2011 Share Posted December 8, 2011 I added it, but I made a typo - so here it is: if ($userGuess<$randNum) { echo "<center>You guessed too low!</center>"; $_SESSION['guesses']++; } if ($userGuess>$randNum) { echo "<center>You guessed too high!</center>"; $_SESSION['guesses']++; } if ($userGuess==$randNum) { echo "<center>Congratulations You're right!!!</center>"; unset($_SESSION["randNum"], $_SESSION['guesses']); } Note the "$_SESSION['guesses']++" lines. Every time they make a wrong guess, the guesses is increment.

helpmehelpmehelpme Posted December 8, 2011 Author Share Posted December 8, 2011 okay, so to print out the counter guesses would you do echo "$_SESSION['guesses'];" Link to comment https://forums.phpfreaks.com/topic/252785-guessing-game-php-with-sessions/#findComment-1295993 Share on other sites More sharing options...
