Was this information Helpful?

Hi, I submitted this as a bug report to the Issue Queue for UC Discounts, but I might as well post it here as well.

http://drupal.org/node/346521

Discounts are being added at checkout, but when it sends it on to PayPal, they get charged the full, non-discounted price. It then shows a negative number, equaling the amount they were overcharged..

Needless to say, this is causing confusion for customers, as they are expecting the sale price, are being shown it in checkout, but then when they pay through PayPal, they get charged the full price..

It DOES work if you do Check/Money Order.. it shows the correct price.. so I'm not sure if this is specific to the PayPal module or not, as I don't have an Authorize.net account to try it out on..

Thanks in advance for any assistance anyone can provide on this..

Further info on the problem

I DID discover that the PayPal form is sending the Item's total, WITHOUT the discount, in the HTML Form. It DOES set the line_item correctly as far as I can tell, what do I need to do for those to show up in PayPal?

Thanks

Debugging with Drubuntu

Well, I DID finally get Drubuntu running with Eclipse for debugging all working, so I will be taking a look into the Discounts not transferring to PayPal problem now..

Will keep everyone updated if I find anything..

Bug found, but not fixed yet

Well I found where the bug is, but haven't fixed it yet... I found it using Drubuntu / PHPEclipse and stepping through the code with the debugger..

Turns out, it's NOT in the Ubercart Discounts module.. this module is using line_item just fine..

It's in the PayPal code.. somewhere.. here is the section where I believe the problem starts. The reason I believe this, is because when using the wps itemized method, the discounts are ignored, but when sent as one single item, the discount IS figured in!

Starting on Line 1280, in uc_paypal.module:

if (variable_get('uc_paypal_wps_submit_method', 'single') == 'itemized') {
    // List individual items
    $i = 0;
    foreach ($order->products as $item) {
      $i++;
      $data['amount_'. $i] = uc_currency_format($item->price, FALSE, FALSE, '.');
      $data['item_name_'. $i] = $item->title;
      $data['item_number_'. $i] = $item->model;
      $data['quantity_'. $i] = $item->qty;

      // PayPal will only display the first two...
      if (is_array($item->data['attributes']) && count($item->data['attributes']) > 0) {
        $o = 0;
        foreach ($item->data['attributes'] as $name => $setting) {
          $data['on'. $o .'_'. $i] = $name;
          $data['os'. $o .'_'. $i] = $setting;
          $o++;
        }
      }
    }
  }
  else {
    // List the whole cart as a single item to account for fees/discounts
    $data['amount_1'] = uc_currency_format($order->order_total - $shipping - $tax, FALSE, FALSE, '.');
    $data['item_name_1'] = t('Order @order_id at @store', array('@order_id' => $order->order_id, '@store' => variable_get('uc_store_name', url('<front>', NULL, NULL, TRUE))));
    $data['on0_1'] = t('Product count');
    $data['os0_1'] = count($order->products);
  }

Now at this point I have no clue what I'm looking at, just that it's not counting the line items properly in the itemized section. Not really sure why this would be, but I will try hacking on the code over the next couple days to try and fix it.. But I'm CONVINCED it's in this section. (Call it an intuition) =)

So, until the code is fixed, I would say setting this setting in the PayPal settings to Single and not Itemized would be the temporary solution, if you're using Discounts.

Re: UC Discounts not sending discount info on to PayPal

You need to make sure that in your paypal wps settings you have it sending the data to paypal as a single line item, all rolled up. Paypal can't handle discounts as a line item. This works for me and is mentioned elsewhere in the ubercart forums. Hope it helps.

Re: Re: UC Discounts not sending discount info on to PayPal

Thanks for that.. =) I think what we need to do, is have the discounts subtracted from the item prices, and not trying to send a Discounts line on to PayPal..

Interesting how we both posted the fix same day, I didn't notice your post until after posting mine. =)

A bug found

I am currently experiencing the same problem. I am using uc_discounts but no discount is being submitted to PayPal despite the fact that all throughout the checkout process the discount is being applied (except on the verify order screen where it displays the PayPal total which is the nondiscounted price - however the discount is being applied in the cart total in the line above it).

I found that this problem is caused when you disable the coupon panel on the checkout pane. If you enable this panel, then it works again. This is a bug that should be fixed as discounts should be applied if the coupon panel is enabled or not.

Re: UC Discounts not sending discount info on to PayPal

I'm also having a similar issue with the uc_discount module for D7. Except my problem is with the payment gateway cybersource.. You can follow that issue -> http://drupal.org/node/1785186#comment-6550144
