Hi All

 

This is not really somthing the paypal developers answer as its general php so thought I would ask on here

 

Basically, have 3 products with 3 item numbers (101,102,103)

 

I have set up if, elseif statements to insert into database depending on the item number. This works fine.

 

However i now want to integrate the quantity. As the purchase will set up a user, i want the inserts to be dependent on the quantity purchased, so if 3 courses are purcased under item number 101 then it sets up 3 user accounts (inserts in to users x3) with the username with an increment of for example [email protected]

 

Can someone pointe me in the correct direction please?

 

Here is the script(including the mail script at bottom but ignore)

 

$fecha = date("m")."/".date("d")."/".date("Y");
$fecha = date("Y").date("m").date("d");

//check if transaction ID has been processed before
$checkquery = "select txnid from paypal_payment_info where txnid='".$txn_id."'";
$sihay = mysql_query($checkquery) or die("Duplicate txn id check query failed:<br>" . mysql_error() . "<br>" . mysql_errno());
$nm = mysql_num_rows($sihay);

if ($nm == 0){

//execute query
if ($itemno == "101"){
