Foreach loop help ----- Calculator . . .

dlf · January 4, 2007

If anyone knows of the Nintendo Wii Virtual Console; that's good, I am making a 'simple' calculator that allows you (regardless of region) to find how many Wii points you would have [i]after[/i] you downloaded some retro games onto the Wii. All I need is help with a foreach loop. Here is the PHP file (that does the interpreting of the form):

<?PHP
// ======================================================================
=====
// NORTH AMERICA
// ======================================================================
=====
$_PRICES['NES'] = 500;
$_PRICES['SNES'] = 800;
$_PRICES['N64'] = 1000;
$_PRICES['GEN'] = 800;
$_PRICES['TURBO'] = 600;
//---------------------------------------------------------------------------
// SOUTH AMERICA
//---------------------------------------------------------------------------
//---------------------------------------------------------------------------
// EUROPE
//---------------------------------------------------------------------------
//---------------------------------------------------------------------------
// ASIA
//---------------------------------------------------------------------------
/*
$_PRICES['FAM'] = 500;
$_PRICES['SFAM'] = 800;
$_PRICES['N64'] = 1000;
$_PRICES['MASTER'] = 800;
$_PRICES['PC'] = 600;
*/
//---------------------------------------------------------------------------
// OTHER
//---------------------------------------------------------------------------

$total = 0;

foreach ($_PRICES as $current_game {

}

?>

Early December I had help with this same thing from my brother; it went onto a (currently down) 'server' as such I can't get the code but from the 1st calclulator I remember the loop having:

$_POST [i]in it (I think [b]$_POST['before'])[/b][/i], [b]$total[/b], [i]+=[/i], [i]$current_game[/i]. And another variable that I can't remember the name or what it was set as.

Also as I said before the PHP file interpreted a form which is:

1st change names of your checkbox - add [] in the end of name (name="NES" => name="NES[]" etc.) [code]
$total = 0;
foreach ($_PRICES as $name => $price) {
$total += count($_POST[$name]) * $price;
}
echo $total;
[/code]

Whoops . . . The original had (for the operators/operands) just +=. & No outside 'functions like count(). The script should actually function like a calculator: Input (select the check boxes of the games) & amount of Wii points you have & it would/will output how many you have left.

Example:

NES are 500 a piece. I 'download' 3 (1500) and have 3,000 'total' (before the download) after I should have 1500. And [i]1500[/i] should be outputted to the screen if I select three NES games & input 3000 wii points.

Sorry for the double post but I [i]do[/i] want this done. Heh.

dlf · January 14, 2007

Sorry for the triple post but may I have some help? The script (wii.php or form.html) does [b]NOT[/B] use functions, if statements, case-statements, tearny operators. Just $_PRICES, $current_game, $_POST, $total, += & a foreach loop.
