Hi guys! I'm going to use paypal with my site, and they have a cool "instant notification" feature which sends, to a page I preassign, information about a transaction as it happens. My script is supposed to: a) receive this information (as a "post") b) send it back to them with a sort of "is this really coming from you?" message c) get a confirmation from them, "yes, this came from us" d) take the post and insert it into my database or whatever else I'd like to do with it.
They have provided a perl sample script (see below). Mostly I'm just trying to figure out how to replicate the whole "receiving", "sending", and "receiving again" thing in PHP. This is especially tricky since I apparently can't test my work without actually going through a transaction on paypal (and spending money). I sorta have to get it right the first time. Anyone done this before? Thanks again! Sondra sample perl script: # read the post from PayPal system and add 'cmd' read (STDIN, $query, $ENV{'CONTENT_LENGTH'}); $query .= '&cmd=_notify-validate'; # post back to PayPal system to validate use LWP::UserAgent; $ua = new LWP::UserAgent; $req = new HTTP::Request 'POST','https://www.paypal.com/cgi-bin/webscr'; $req->content_type('application/x-www-form-urlencoded'); $req->content($query); $res = $ua->request($req); # split posted variables into pairs @pairs = split(/&/, $query); $count = 0; foreach $pair (@pairs) { ($name, $value) = split(/=/, $pair); $value =~ tr/+/ /; $value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg; $variable{$name} = $value; $count++; } # assign posted variables to local variables $receiver_email = $variable{'receiver_email'}; $item_name = $variable{'item_name'}; $item_number = $variable{'item_number'}; $custom = $variable{'custom'}; $payment_status = $variable{'payment_status'}; $payment_date = $variable{'payment_date'}; $payment_gross = $variable{'payment_gross'}; $payment_fee = $variable{'payment_fee'}; $txn_id = $variable{'txn_id'}; $first_name = $variable{'first_name'}; $last_name = $variable{'last_name'}; $address_street = $variable{'address_street'}; $address_city = $variable{'address_city'}; $address_state = $variable{'address_state'}; $address_zip = $variable{'address_zip'}; $address_country = $variable{'address_country'}; $payer_email = $variable{'payer_email'}; if ($res->content eq 'VERIFIED') { # check transaction for uniqueness # process payment } elsif ($res->content eq 'INVALID') { # possible fraud } else { # error } -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
