I don't have a custom tag, but this is pretty easy. Maybe I can save you and others some time reading: <FORM ACTION="https://www.paypal.com/cgi-bin/webscr"; METHOD="POST" target="<CFOUTPUT>#target#</CFOUTPUT>"> <INPUT TYPE="hidden" NAME="cmd" VALUE="_ext-enter"> <INPUT TYPE="hidden" NAME="redirect_cmd" VALUE="_xclick"> <CFOUTPUT> <input type="hidden" name="custom" value="#thisorderid#"> <input type="hidden" name="notify_URL" value="http://yourdomain.com/paypal_IPN.cfm";> <INPUT TYPE="hidden" NAME="business" VALUE="#PayPalID#"> <INPUT TYPE="hidden" NAME="first_name" VALUE="#firstname#"> <INPUT TYPE="hidden" NAME="last_name" VALUE="#lastname#"> <INPUT TYPE="hidden" NAME="address1" VALUE="#address#"> <INPUT TYPE="hidden" NAME="address2" VALUE="#address2#"> <INPUT TYPE="hidden" NAME="city" VALUE="#city#"> <INPUT TYPE="hidden" NAME="state" VALUE="#state#"> <INPUT TYPE="hidden" NAME="zip" VALUE="#zip#"> <INPUT TYPE="hidden" NAME="return" VALUE="#GetSetup.Home#"> <CFIF GetSetup.shipcountry IS NOT "1"><INPUT TYPE="hidden" NAME="no_intl" VALUE="1"></CFIF> <INPUT TYPE="hidden" NAME="item_name" VALUE="XXX Order No. #thisorderid#"> <input type="hidden" name="amount" value="#Trim(numberformat(variables.grandtotal, '_____.00'))#"> <INPUT TYPE="image" SRC="#GetSetup.Server#ezcart/buttons/x-click-but2.gif" NAME="submit" ALT="Make payments with PayPal - it's fast, free and secure!" width="72" height="29" border="0"></CFOUTPUT> </FORM> This will pass the amount as a single item, called "XXX Order No. 123" with the order total, including shipping and taxes as the price. Obviously you'll replace XXX and 123 with your company name and order number. The first field, "custom", I pass with the order ID. This field will be passed back to the Instant Payment Notification page on your server. Here is what I use for the paypal_IPN.cfm page I created (notify_URL field), which notifies the merchant when the order is approved and flags the order approved in the database. Notes afterward. Note that if you use their documentation, there is a typo in the ColdFusion example. I don't remember "exactly" what it was, but it was in the "str" variable (at the top) that is created to pass back to PayPal. A & where the ? should be or a missing & something like that. <CFPARAM NAME="variables.invoice" DEFAULT="0"> <!--- read post from PayPal system and add 'cmd' ---> <CFSET str="cmd=_notify-validate"> <CFLOOP INDEX="TheField" list="#Form.FieldNames#"> <CFSET str = str & "&#LCase(TheField)#=#URLEncodedFormat(Evaluate(TheField))#"> </CFLOOP> <CFIF IsDefined("FORM.payment_date")> <CFSET str = str & "&payment_date=#URLEncodedFormat(Form.payment_date)#"> </CFIF> <CFIF IsDefined("FORM.subscr_date")> <CFSET str = str & "&subscr_date=#URLEncodedFormat(Form.subscr_date)#"> </CFIF> <!--- post back to PayPal system to validate ---> <CFHTTP URL="https://www.paypal.com/cgi-bin/webscr?#str#"; METHOD="GET" RESOLVEURL="false"> </CFHTTP> <!--- <CFOUTPUT>#cfhttp.filecontent#</CFOUTPUT> ---> <!--- check notification validation ---> <CFIF CFHTTP.FileContent contains "VERIFIED" and isDefined('form.payment_status') and isDefined('form.custom') and isNumeric(form.custom) and isDefined('form.receiver_email') and (form.receiver_email is PayPalID or (form.receiver_email is AlternatePayPalID and AlternatePayPalID is not ""))> <cfswitch expression="#form.payment_status#"> <cfcase value = "Completed"> <cfset variables.payment_status = "This charge was authorized"> <cfset variables.approval_notify = form.custom> </cfcase> <cfcase value = "Pending"> <cfset variables.payment_status = "Pending - #form.pending_reason#"> </cfcase> </cfswitch> <cfset variables.invoice = int(val(form.custom))> <CFELSEIF #CFHTTP.FileContent# contains "INVALID"> <cfset variables.payment_status = "INVALID PAYPAL TRANSACTION"> <CFIF isDefined('form.custom')><cfset variables.invoice = int(form.custom)></CFIF> <CFELSE> <!--- error ---> </CFIF> <CFIF isDefined('variables.payment_status') and variables.invoice GT 0> [Update query flag order number #variables.invoice# as approved in database here] </CFIF> <CFIF isDefined('variables.approval_notify')> <cfmail from="youremailaddress" to="youremailaddress" subject="Order #variables.approval_notify# Approved"> Order #variables.approval_notify# Approved </cfmail> </CFIF> The reason I use both PayPalID and AlternatePayPalID (which are the merchant's PayPay e-mail addresses) is that some people have multiple PayPal IDs. If they are notified at a different address than they use for their initial submission, this will fail. I tested it pretty thoroughly, and it works good. The one thing I haven't tested is whether or not the "custom" field still get's passed back a week later if the user pays by check and it's approved. I suspect it is though. -- Bud Schneehagen - Tropical Web Creations _/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/ ColdFusion Solutions / eCommerce Development [EMAIL PROTECTED] http://www.twcreations.com/ 954.721.3452 ______________________________________________________________________ Structure your ColdFusion code with Fusebox.
