Sale and transaction variables/values

[IgnasiVP]

Hello, I'm installing an affiliates module for Prestashop 1.5 and the instructions say:

 

 

(iFrame code omitted)

• Replace the $SALE with your actual sale variable.
  
• Replace the $ORDER_ID with your actual order ID or transaction ID variable
  
• On a PHP thank you page, make sure to add it in as PHP code, for example:
   
  <?=$SALE?>
  <?=$ORDER_ID?>
  

 

 

I don't understand what I have to change here...

 

It says "All you need is the sale and transaction values that your cart or gateway uses after a sale has been made. Your shopping cart or payment processor can usually tell you what these are if you do not know them."

 

Do you know anything that might be helpful ? Thank you very much!.
