For a recent job, I started working on a download store. Basically, the customer wanted to be able to sell collections of MP3s, but they could be downloadable books or PDFs or what ever.
I had previously seen that the free WP e-Commerce plugin for Word Press has a downloadable product option, so I grabbed the plugin and checked it out.
Few quick things:
- The Upload tool for the files only goes up to 8mb. Upload larger files straight to your server at /wp-content/uploads/wpsc/downloadable then they will be an option from the individual product page, near the bottom
- If using PayPal, you need to fiddle with the Instant Payment Notification settings a touch to get the payment info back from Paypal. Honestly, I am still help up on this step and it might be enough that I can’t use WP e-Commerce if its not resolved.
Here are the basic steps for setting up Paypal with WP e-Commerce download store.
WP e-Commerce
In your Word Press Admin
Go to WordPress/ e-Commerce/ settings… “Payment”
Payment Gateway: Paypal (not express)
PayPal Username: paypal account you wish to send the money to
PayPal Url: https://www.paypal.com/cgi-bin/webscr
PayPal IPN: YesOn Your PayPal Admin
Select Account -> Profile -> Instant Payment Notification preferences (Under Selling preferences)
IPN: ON
IPN-URL: http://your_domain.com/?ipn_request=trueUnder Select Account -> Profile -> Website Payment Preferences (Under Hosted payment settings)
Auto Return: ON
Return URL: copy-paste your “Transaction URL” from e-Commerce/ settings
Payment Data Transfer: ON
As I write this, I have gotten hung up because the Order status come back from PayPal as ‘Order received’ and need to be ‘Payment Accepted’ in order to create the link to download the item

If I can’t get this working today, I’ll scrap using WP e-Commerce and look for another cart.
Bummer, I will have wasted a lot of time on WP e-Commerce
Still working on this while installing a different cart
the URL from PayPal looks something like
http://www.domainname.com/location/transaction-results/?sessionid=851125571xxxx&gateway=paypal&tx=2V6885633X99xxx&st=Pending&amt=0.01&cc=EUR&cm=&item_number=
st=Pending is what gets my attention
Does anyone know that status WP e-Commerce wants in order to move the order straight to Accepted or Closed?
I have tried Accept, Closed, Accepted, but all after the fact
I email Godaddy and they claim not to block anything that would prevent the IPN from doing its job
This leave me at a PayPal setting that will return Accepted or Closed or what ever, or hacking WP e-Commerce to always set the status to what ever WP e-Commerce wants in order to release the download link. Seems like a lot of freaking work in order to sell an MP3
From PayPal
https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_html_IPNandPDTVariables
So these variables being returned are actually PDT values, not IPN
Description
amt Amount of the transaction
cc Currency code
cm Custom message
st Transaction status
tx Transaction ID/PDT token
So I presume st ( Transaction status) is like payment_status. I presume this because its the only variable that come in Uppercase and has the possible value of Pending.
But bummer for me, switching that value in the URL to Completed does not push the order to a status that will display the links to the downloadable media.
