i have a class which
in which iam using a method to get information from a session array via a for loop
the 2 for loops
in each method are used 1.to count total amount of items , and 2. to add up
the total price but neither seem to be returning anything. im using
the total amount to check it against
the mc_gross posted value from an IPN and if
the values are equal i plan to commit
the sale to a database as it has been verified. for
the method where im looking to get
the total price im getting 0.00 returned to me. i think ive got
the syntax wrong here somehow here is my class for purchase
the two methods iam having trouble with are
the gettotalcost() and gettotalitems() shown below is my class.
<?php
class purchase {
private $itemnames; // from session array
private $amountofitems; // from session array
private $itemcost; //session array
private $saleid; //posted transaction id value to be used
in sale and sale item tables
private $orderdate; //get current date time to be entered as datetime
in sale table
private $lastname; //posted from ipn
private $firstname; //posted from ipn
private $emailadd; //uses sessionarray value
public function __construct($saleid,$firstname,$lastname)
{
$this->itemnames = $_SESSION['itemnames'];
$this->amountofitems =$_SESSION['quantity'];
$this->itemcost =$_SESSION['price'];
$this->saleid = $saleid;
$this->firstname = $firstname;
$this->lastname = $lastname;
$this->emailadd = $SESSION['username'];
mail($myemail, "session vardump ", echo var_dump($_SESSION), "From:
[email protected]" );
mail($myemail, "session vardump ",count($_SESSION['itemnames']) , "From:
[email protected]" );
}
public function commit()
{
$databaseinst = database::getinstance();
$databaseinst->connect();
$numrows = $databaseinst->querydb($query);
//to be completed
}
public function gettotalitems()
{
$numitems;
$i;
for($i=0; $i < count($this->amountofitems);$i++)
{
$numitems += (int) $this->amountofitems[$i];
}
return $numitems;
}
public function gettotalcost()
{
$totalcost;
$i;
for($i=0; $i < count($this->amountofitems);$i++)
{
$numitems = (int) $this->amountofitems[$i];
$costofitem =doubleval($this->itemcost [$i]);
$totalcost += $numitems * $costofitem;
}
return $totalcost;
}
}
?>
and here is where i create an instance of
the class and attempt to use it.
include("purchase.php");
$purchase = new purchase($_POST['txn_id'],$_POST['first_name'],$_POST['last_name']);
$fullamount = $purchase->gettotalcost();
$fullAmount = number_format($fullAmount, 2);
$grossAmount = $_POST['mc_gross'];
if ($fullAmount != $grossAmount) {
$message = "Possible Price
Jack attempt!
the amount
the customer payed is : " . $grossAmount .
" which is not equal to
the full amount.
the price of
the products combined is " . $fullAmount. "
the transaction number for which is " . $_POST['txn_id'] . "\n\n\n$req";
mail("XXXXXXXXXXXX", "Price
Jack attempt ", $message, "From:
[email protected]" );
exit(); // exit
}

the help

in the vardump uh oh!
