[RESOLVED] saving a randomly selected number

[eclipser221]

ok. I am in the process of creating a web based game. I have a page that randomly selects a monster from a database that is the users level. but when you hit attack it randomly selects a new monster. please help me so it will randomly select a monster once instead of every time you submit it.

here is the code for the page.

 <?php
include("/../../wamp/www/test/includes/db_connect.php");
include("/../../wamp/www/test/includes/userauth.php");

$sql = "SELECT * FROM monsters WHERE mon_level = $userlevel ORDER BY RAND() LIMIT 1";
$query = mysql_query($sql) or die(msql_error());
$mon = mysql_fetch_array($query);

if(isset($_POST['fight'])) {
if($userhp >> 0) {

echo "You encounter a ".$mon['mon_name'].".";
echo "<br>What would you like to do?";
echo '<br><form action="'.$_SERVER['PHP_SELF'].'" method="post">
			<input type="submit" name="attack" value="Attack">
			<input type="submit" name="run" value="Run">
			</form>';
exit;
}// if userhp > 0
else {
echo "You are dead. You can not attack anything.";
exit;
}// else
}// if post is fight

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

$monhp = $mon['mon_hp'];
$monname = $mon['mon_name'];
$monattack = $mon['mon_dam'];
$dammin = $monattack - 2;
$dammax = $monattack + 2;
$mondam = rand($dammin,$dammax);

echo 'The '.$mon['mon_name'].' has '.$monhp.' health.
	  <br>You have '.$userhp.' health.
	  <br><br>The monster hits you for '.$mondam.'.';

$userhp = $userhp - $mondam;

if($userhp <= 0) {
$userhp = 0;
}

$sql = "UPDATE users set user_hp = '".$userhp."' WHERE user_name = '".$username."'";
mysql_query($sql) or die(mysql_error());


echo '<br>You have '.$userhp.' health left.';

if($userhp <= 0){
echo '<br><br>You have died and must go back to town to heal.';
exit;
}

echo '<br><form action="'.$_SERVER['PHP_SELF'].'" method="post">
			<input type="submit" name="attack" value="Attack">
			<input type="submit" name="run" value="Run">
			</form>';

exit;
}
if($userhp >> 0) {
echo '<form action="'.$_SERVER['PHP_SELF'].'" method="post">
	  <input type="submit" name="fight" value="Find something to fight">';
	  exit;
}// if hp is not 0
else {
echo "You are dead. You can not attack anything.";
exit;
}// else
?>

all the user variables are set on the user auth page.

i have tried to use a $_session[] but i did not have luck with this. i may have not done it right.

any help would be appreciated.

How did you try and implement your $_SESSION?

That would be a good way to do solve your problem.

[eclipser221]

if(isset($_session['monster'])) {
$monsterid = $_session['monster'];
}
else {
$sql = "SELECT * FROM monsters WHERE mon_level = $userlevel ORDER BY RAND() LIMIT 1";
$query = mysql_query($sql) or die(msql_error());
$mon = mysql_fetch_array($query);
$_session['monster'] = $mon['mon_id'];
$monsterid = $mon['mon_id'];
}

and then down where it checks hp it is

if($monhp <= 0 or $userhp <= 0) {
unset($_session['monster']);
}

You NEED to use session_start() to use sessions and your $session needs to be ALL UPPERCASE like $SESSION
