For the load game PHP file, you need to do the following:
<?php
session_start();
// connect to SQL and get table row, then...
$_SESSION['platinum'] = $SQL->platinum
// repeat the line of code above for each variable that you want
// to load, you will need to get the ID of the table row as well.
// you might want to let people choose a username that cannot
// be duplicated, so that people can't overwrite other people's
// games with their saves (prevent accidents before they happen)
?>
And to save...
<?php
session_start();
mysql_query ("update `players` set `energy` = '$_SESSION['energy']', `platinum` = '$_SESSION['platinum'];")
// repeat the "set `field` = '$_SESSION['field']," piece of code
// above for each variable that you want
// to save, you will need to save the ID of the table row as well.
// you might want to let people choose a username that cannot
// be duplicated, so that people can't overwrite other people's
// games with their saves (prevent accidents before they happen)
?>
And for a new game, you need to do the following:
<?php
session_start();
// insert a new row into the table with the player's chosen name
// and password, if necessary as the only thing in the
// row. if you leave the default values of the row in the table to
// the new game settings, then you will automatically have a new
// game set up when you execute the next code.
mysql_query("insert into `players` (`username`,`password`) VALUES ('$username',PASSWORD('$password')")
// connect to SQL and get table row, then...
$_SESSION['platinum'] = $SQL->platinum
// repeat the piece of code
// above for each variable that you want
// to set, you will need to save the ID of the table row as well.
// you might want to let people choose a username that cannot
// be duplicated, so that people can't overwrite other people's
// games with their saves (prevent accidents before they happen)
?>
I really hope that this helps you.
