Problems with Dynamic Voucher Codes

Problems with Dynamic Voucher Codes

Hi all,
I have a site (www.piccolaonline.co.uk) who I am adding a dynamic voucher system for.

After following the pdf tutorial on adding a static voucher code and getting it to work, I then followed the method given by Jason (showpost.php?p=23007&postcount=2) to convert the voucher system to a dynamic one....but I can't get it to work!!!

If you go to the site and add some stuff to the cart and enter voucher code 'test15', you will see that the discount is not applied, but an echo of the recordset appears next to the voucher box - it shows the voucher code (test15) and the amount (0.15 for 15% as descibed in the method).

The sessions required have been added....but nothing happens!!!

Any ideas would be great...I've attached the cart page and a couple of others..

Thank you!

Martin

the problem is code order.


the code to set the session variables is at lines 13 - 24:

php:
<?php

if (!session_id()) session_start();
if(!(
$totalRows_rs_coupon == 0))     {
  
$_SESSION["PromoCode"] = "".$row_rs_coupon['code_vch']  ."";
}
?>
<?php
if (!session_id()) session_start();
if(!(
$totalRows_rs_coupon == 0))     {
  
$_SESSION["PromoAmount"] = "".$row_rs_coupon['amount_vch']  ."";
}
?>




this is before the code to create the recordset which is at line 76 - 80, since the recordset does not exist yet when the session is being set, the session is set to a blank value.


move the set session value code so it is after the recordset code.

Great! Thanks again for your invaluable help, Jason...your solution works a treat!

I've managed to add a minimum order criteria to the list of server sessions etc...but now have an issue with adding a time limit to a dynamic voucher code.

I've done this:
1: added an expiry date in the database as yyyy-mm-dd
2: added a session value called 'PromoDate' (in the same place as you told me to with the others)
3: in the e-cart discount definition, I did this:
i: added an AND condition of 'If today is before a certain day'
ii: in the value for the above, I put $_SESSION['PromoDate']
4: I left the calculation alone
5: saved everything and uploaded it....and it crashed the entire site with 500 internal server error.

I thought it all made perfect sense, but now I am not too sure. Could you pleased help me out again?

Many thanks,

Martin

in the piccCart_PHP.php file, change the following code:

php:
if (true && ((sizeof($this->Items) > 0) && (isset($_SESSION['PromoCode'])) && (isset($_SESSION['PromoAmount'])) && ($this->TotalColumn("TotalPrice") > $_SESSION['PromoMin']) && (time() <= strtotime("$_SESSION['PromoDate']")))) {


to:

php:
if (true && ((sizeof($this->Items) > 0) && (isset($_SESSION['PromoCode'])) && (isset($_SESSION['PromoAmount'])) && ($this->TotalColumn("TotalPrice") > $_SESSION['PromoMin']) && (time() <= strtotime($_SESSION['PromoDate'])))) {
