Text field data from PayPal button payment is not grabbed in Classic API NVP transaction details call

Question

I'm calling GetTransactionDetails with NVP using the code from List of PayPal transactions

The HTML for the PayPal button look likes

<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="XXXXXXXXXXXXX"> PLACEHOLDER VALUE
<table>
<tr><td><input type="hidden" name="on0" value="Tier Selection">Tier Selection</td></tr><tr><td><select name="os0">
<option value="Tier 1">Tier 1 $15.00 USD</option>
<option value="Tier 2">Tier 2 $30.00 USD</option>
<option value="Tier 3">Tier 3 $50.00 USD</option>
<option value="Tier 4">Tier 4 $200.00 USD</option>
<option value="Tier 5">Tier 5 $500.00 USD</option>
<option value="Tier 6">Tier 6 $1,000.00 USD</option>
</select> </td></tr>
<tr><td><input type="hidden" name="on1" value="Name for Product">Name for Product</td></tr><tr><td><input type="text" name="os1" maxlength="200"></td></tr>
<tr><td><input type="hidden" name="on2" value="Forum Email Address">Forum Email Address</td></tr><tr><td><input type="text" name="os2" maxlength="200"></td></tr>
</table>
<input type="hidden" name="currency_code" value="USD">
<input type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_paynowCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
<img alt="" border="0" src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" height="1">
</form>

Tne NVP call returns (after parse_str)

L_OPTIONSNAME0 => Tier Selection
L_OPTIONSNAME1 => Name for Product
L_OPTIONSVALUE0 => Tier 1
L_OPTIONSVALUE1 => NAME
L_OPTIONS1NAME0 => Name for Product
L_OPTIONS1VALUE0 => NAME

The "Name for Product" data is returned twice and the "Forum Email Address" is not returned. The "Forum Email Address" data is displayed properly under Item Title when I view Transaction Details on the PayPal website. And as a side note when I export transactions to CSV the "Forum Email Address" data is not being exported.

I plan on writing a script that would automatically add the "Forum Email Address" data to a private forum on my site by using the PayPal API.

Is the duplicate name/value entry a bug?

Answer 1

From a quick glance at your code it looks like you have everything set correctly. I am not aware of any bugs for this issue off hand. However, I would suggest opening up a ticket with PayPal's Merchant Technical Support so that this can be looked into further and a bug filed for this if needed.
