require("dbfunctions.inc.php");
$count;


class Product
{
// The following are the attributes of the Product class, that is,

var $prodcode = array();
var $name = array();
var $price = array();
/* 	CONSTRUCTOR
	Every class has at least one constructor method. We create an instance of a class
	using the class's constructor
*/

function AllProducts()
{
	$qry = "Select ProdCode, Name, Price, Image from products";

//execute query
$products = execute_query($qry);


if (!$products)
{die('query failed.');
}
	$i = 0;
	global $count;  
	$count= mysql_num_rows($products);
	while ($line = mysql_fetch_array($products, MYSQL_ASSOC)) 
{ 
	$prodcode =array ($line['ProdCode']);

	//echo "<tr><td>";
	echo "<br>Product Code: <a href=DisplayProduct.php?prodcode=" . $prodcode[$i].
		">" .$prodcode[$i]. "</a>"."<br>";
	echo  "Product Name: ".$name[$i]." <br>". "Price: FJD$ " .$price[$i]."<br>";

// Method to print the Shopping Cart details to the screen
function getProdCode()
{

	echo "Product Code: " . $this->prodcode . "<br>"; 

} 



} // END OF CLASS

those variables are undefined, "not set" in that function.

[babaz]

but it does not cause any errors when it is used in AllProducts function.

[BlueSkyIS]

because all variables are defined in the AllProducts function, for instance prodcode is defined thusly in AllProducts:

 

$prodcode =array ($line['ProdCode']);
