Add new variable to send to paypal

Well, this is pretty simple. I've got eCart up and running and it works great. It is hooked into my sql database and I have no problems. But, I decided I want to include the item SKU on the paypal payment screen. Is there an easy way to pass my variable, itemSKU, to the paypal payment screen which has the order details?

What paypal system are you using? If paypal payments standard:


look for the following code on the confirm page:

(this code is generated using a cart object named "eCart2", your will be slightly different depending on the cart object name)

<input type="hidden" name="on0_<?php echo $eCart2_Index+1; ?>" id="on0_<?php echo $eCart2_Index+1; ?>" value="" />

<input type="hidden" name="os0_<?php echo $eCart2_Index+1; ?>" id="os0_<?php echo $eCart2_Index+1; ?>" value="" />

this is a variable pair used to pass optional information. set the value of the first one to "SKU"

for the second one, in the property inspector, click the lightning bolt next to initial value and select the SKU cart column.

Thanks, that worked great! One other question, though. On the paypal page it displays the following

Options: SKU: [my sku]

I could leave the first variable blank so it just display Options: [my SKU], but I wonder, could the label for "Options:" be changed to reflect "SKU:"?

I have a feeling the answer is no...

No, paypal automatically adds the options label, then will show the label that you provide followed by the value.
