Rock paper scissors...

Hey, I'm trying RPS with forms, here it is so far...

code:

And the script to compliment the first one...

The one below is rpsform.php.

code:

<?

$input = array("scissors", "paper", "rock");
$total_array = count($input);
$rand_keys = array_rand($input, $total_array);

if(isset($_POST['choice'])) {

$choice = $_POST['choice'];

if ($input == 'rock' && $choice == 'scissors')
{
echo 'You chose scissors, 
Computer chose rock 
You lose!';
}
elseif ($input[$rand_keys[0]] == 'rock' && $choice == 'paper')
{
echo 'You chose paper 
Computer chose rock 
You win!';
}
elseif ($input[$rand_keys[0]] == 'scissors' && $choice == 'rock')
{
echo 'You chose rock, 
Computer chose scissors 
You win!';
}
elseif ($input[$rand_keys[0]] == 'scissors' && $choice == 'paper')
{
echo 'You chose paper, 
Computer chose scissors 
You lose!';
}
elseif ($input[$rand_keys[0]] == 'paper' && $choice == 'rock')
{
echo 'You chose rock, 
Computer chose paper 
You lose!';
}
elseif ($input[$rand_keys[0]] == 'paper' && $choice == 'scissors')
{
echo 'You chose scissors, 
Computer chose paper 
You win!';
} elseif($user == $input[$rand_keys[0]]) {
echo 'It\'s a tie!';
} else {
echo 'sorry, only rock, paper and scissors are allowed its case-sensitive';
}

?>

Whenever I click the button though in the first script, nothing happens. Anyone know what's wrong?

ah, well you see for you to click a button and make it to submit stuff in the form, you have to make it's type 'SUBMIT'

And just for fun, let's refactor!

Not tested.

code:

<html>
<head>
<title>Rock, Paper, Scissors</title>
</head>
<body>
<?php
$possible_choices = array(
"rock" => array(
"item" => "rock",
"defeats" => "scissors",
"defeated_by" => "paper";),
"paper" => array(
"item" => "paper",
"defeats" => "rock",
"defeated_by" => "scissors"),
"scissors" => array(
"item" => "scissors".
"defeats" => "paper",
"defeated_by" => "rock"));

function form_submitted() {
return isset($_REQUEST["choice"]);
}

function rps_computer_choice($possible_choices_array) {
return array_rand($possible_choices_array);
}

function rps_user_wins($user_choice, $computer_choice) {
$computers_choice = rps_computer_choice($possible_choices);
if ($user_choice["defeats"] == $computers_choice["item"])
return 1;
elseif ($user_choice["item"] == $computers_choice["item"])
return 0;
elseif ($user_choice["defeated_by"] == $computers_choice["item"])
return -1;
}

function rps_get_user_choice($possible_choices) {
if (form_submitted()) {
return $possible_choices[$_REQUEST["choice"]];
} else {
echo("I chose for you, since your input was wrong.<hr/>");
return rps_computer_choice($possible_choices);
}
}

function rps_outcome_message($user_choice, $computer_choice) {
switch (rps_user_wins($user_choice, $computer_choice)) {
case 1:
return "You win!";
case 0:
return "It's a tie!";
case -1:
return "Computer wins!";
}
}

function rps_echo_choices($user_choice, $computer_choice) {
echo("The computer chose " . $computers_choice["item"] . " ");
echo("You chose " . $user_choice["item"] . " ");
}

// and here it is:

if (form_submitted()) {
$users_choice = rps_get_user_choice($possible_choices);
$computer_choice = rps_computer_choice($possible_choices);

rps_echo_choices($users_choice, $computer_choice);
echo(rps_outcome_message($users_choice, $computer_choice));

echo(" <hr/> ");
echo("Play again!");
echo(" <hr/> ");
}
?>
<FORM METHOD="POST" ACTION="<?= basename($PHP_SELF) ?>">
<INPUT TYPE="button" name="choice" value="rock"/>
 
<INPUT TYPE="button" name="choice" value="scissors"/>
 
<INPUT TYPE="button" name="choice" value="paper"/>
</FORM>
</body>
</html>

Okay, now I'm using sessions on this as well.

This is rps1.php

code:

<form METHOD="POST" ACTION="rpsform.php">

<INPUT TYPE="submit" name="choice" value="rock">
 

<INPUT TYPE="submit" name="choice" value="scissors"> 

<INPUT TYPE="submit" name="choice" value="paper">
 
 
 
</form>
<?

session_start();
if(!isset($_SESSION['wins'])) or
(!isset($_SESSION['losses'])) or
(!isset($_SESSION['ties']))
echo "Sorry, you have not started a session. Play a game to start a session and keep your game record.";

else
echo "<center> Wins: $_SESSION['wins']" </center> 

echo "<center> Losses: $_SESSION['losses']" </center> 

echo "<center> ties: $_SESSION['ties']" </center> 
?>

And to compliment it, rpsform.php.

code:

<?
srand((float) microtime() * 10000000);
$input = array("scissors", "paper", "rock");
$total_array = count($input);
$rand_keys = array_rand($input, $total_array);

if(isset($_POST['choice'])) {

$choice = $HTTP_POST_VARS['choice'];

session_start();
if(!isset($_SESSION['count'])) {
session_register('wins')
session_register('losses')
session_register('ties')
$HTTP_SESSION_VARS['wins'] = 0
$HTTP_SESSION_VARS['losses'] = 0
$HTTP_SESSION_VARS['ties'] = 0;

if ($input == 'rock' && $choice == 'scissors')
{
echo 'You chose scissors, 
Computer chose rock 
You lose!'
$HTTP_SESSION_VARS['losses'] ++;
}
elseif ($input[$rand_keys[0]] == 'rock' && $choice == 'paper')
{
echo 'You chose paper 
Computer chose rock 
You win!'
$HTTP_SESSION_VARS['wins'] ++;
}
elseif ($input[$rand_keys[0]] == 'scissors' && $choice == 'rock')
{
echo 'You chose rock, 
Computer chose scissors 
You win!'
$HTTP_SESSION_VARS['wins'] ++;
}
elseif ($input[$rand_keys[0]] == 'scissors' && $choice == 'paper')
{
echo 'You chose paper, 
Computer chose scissors 
You lose!'
$HTTP_SESSION_VARS['losses'] ++;
}
elseif ($input[$rand_keys[0]] == 'paper' && $choice == 'rock')
{
echo 'You chose rock, 
Computer chose paper 
You lose!'
$HTTP_SESSION_VARS['losses'] ++;
}
elseif ($input[$rand_keys[0]] == 'paper' && $choice == 'scissors')
{
echo 'You chose scissors, 
Computer chose paper 
You win!'
$HTTP_SESSION_VARS['win'] ++;
} elseif($user == $input[$rand_keys[0]]) {
echo 'It\'s a tie!'
$HTTP_SESSION_VARS['ties'] ++;;
} else {
echo 'sorry, only rock, paper and scissors are allowed its case-sensitive';
}

}
<center> echo Wins: $HTTP_SESSION_VARS['wins'] </center>;
<center> echo Losses: $HTTP_SESSION_VARS['losses'] </center>;
<center> echo Ties: $HTTP_SESSION_VARS['ties'] </center>;

<form METHOD="POST" ACTION="rps1.html">

<input type="submit" value="Play Again!"
</form>

?>

So this should display the wins, losses, and ties on both rps1.php and rpsform.php. But, it only shows the scores on rpsform.php. Anyone know what's wrong?

for your rpsform.php

code:

<?
srand((float) microtime() * 10000000);
$input = array("scissors", "paper", "rock");
$total_array = count($input);
$rand_keys = array_rand($input, $total_array);

if(isset($_POST['choice'])) {

$choice = $HTTP_POST_VARS['choice'];

if(!isset($_SESSION['count'])) {
session_start();

session_register('wins');
session_register('losses');
session_register('ties');

if(!isset($HTTP_SESSION_VARS['wins'])) $HTTP_SESSION_VARS['wins'] = 0;
if(!isset($HTTP_SESSION_VARS['ties'])) $HTTP_SESSION_VARS['ties'] = 0;
if(!isset($HTTP_SESSION_VARS['losses'])) $HTTP_SESSION_VARS['losses'] = 0;

if ($input[$rand_keys[0]] == 'rock' && $choice == 'scissors')
{
echo 'You chose scissors, 
Computer chose rock 
You lose!';
$HTTP_SESSION_VARS['losses']++;
}
elseif ($input[$rand_keys[0]] == 'rock' && $choice == 'paper')
{
echo 'You chose paper 
Computer chose rock 
You win!';
$HTTP_SESSION_VARS['wins']++;
}
elseif ($input[$rand_keys[0]] == 'scissors' && $choice == 'rock')
{
echo 'You chose rock, 
Computer chose scissors 
You win!';
$HTTP_SESSION_VARS['wins']++;
}
elseif ($input[$rand_keys[0]] == 'scissors' && $choice == 'paper')
{
echo 'You chose paper, 
Computer chose scissors 
You lose!';
$HTTP_SESSION_VARS['losses']++;
}
elseif ($input[$rand_keys[0]] == 'paper' && $choice == 'rock')
{
echo 'You chose rock, 
Computer chose paper 
You lose!';
$HTTP_SESSION_VARS['losses']++;
}
elseif ($input[$rand_keys[0]] == 'paper' && $choice == 'scissors')
{
echo 'You chose scissors, 
Computer chose paper 
You win!';
$HTTP_SESSION_VARS['wins']++;
} elseif($choice == $input[$rand_keys[0]]) {
echo 'It\'s a tie!';
$HTTP_SESSION_VARS['ties']++;;
} else {
echo 'sorry, only rock, paper and scissors are allowed its case-sensitive';
}

}

echo '<center> echo Wins: '. $HTTP_SESSION_VARS['wins'] .' </center>
<center> echo Losses: '. $HTTP_SESSION_VARS['losses'] .' </center>
<center> echo Ties: '. $HTTP_SESSION_VARS['ties'] .' </center>';
} // if(!isset($_SESSION['count'])) {

echo '<form METHOD="POST" ACTION="rps1.php">
<input type="submit" value="Play Again!">
</form>';
