Question

I use following code for the RETURN URL.

 @foreach (var item in Model)
                    {
                        <form action='@item.PayPalURL2 ' method='post'>
                            <input type='hidden' name='cmd' value='_xclick' />
                            <input type='hidden' name='business' value='@item.BusinessEmail' />
                            <input name='item_name' value='@item.Name' class="ppField" readonly="readonly"/>
                            <input type='hidden' name='item_number'  value='@item.ID' />
                            <input name='amount' value='@item.Price2' class="ppField" readonly="readonly"/>
                            <input type='hidden' name='return' value='@item.ReturnURL' />
                            <input type='hidden' name='custom' value='@item.UserID' />
                            <input type='submit' value='Buy' />
                        </form>
                    }

Any clue how to pass custom filed to IPN message and get it via Listener?

Thank you!!!

You’ve already got the “custom” field included in your form. Whatever value you have in @item.UserID will be getting sent along with the payment and will come back as a POST value called “custom” within your IPN solution.

So, it looks like you’re already got what you need. You just need to make sure $item.UserID actually contains what you expect it to contain, and that you’re looking for the custom field in your IPN listener.
