PayPal hookup - Connecting the buttons with vouchers and profiles

• We assume the following options on our PayPal button:

• We also assume you have the following Profiles defined in the Profiles applet:

SELECT * FROM profiles;
SELECT * FROM realms;
SELECT * FROM users;

• We further assume you have a Realm with the following detail:

• Finally we want to make the owner of these vouchers an Access Provider called admin_college

• We can now use the above info and edit the /usr/share/nginx/html/cake2/rd_cake/Config/RadiusDesk.php file to look like this:

//Use this as a reference to complete the other three
//From Paypal data 'item_name' (RDVoucher') 'item_number' (rd_v1) option_selection1 ('1GB')
$config['paypal']['RDVoucher']['rd_v1']['1GB'] = array(
                                                        'precede'           => '',
                                                        'profile_id'        => 9,
                                                        'profile'           => 'Data-Standard-1G',
                                                        'realm_id'          => 34,
                                                        'realm'             => 'Residence Inn',
                                                        'sel_language'      => '4_4',
                                                        'user_id'           => '182'
                                                    );

• Be sure to use revision 1073 or higher for the FinPaypalTransactionsController.php controller in order to include support for single field vouchers.
• Also ensure that you supply both the realm name and id as well as the profile name and id in the voucher definition.
• Next we will configure the SMTP setup for the CakePHP application in order for us to email the voucher details to the person who purchased the voucher.

• If you want to run your own SMTP server then the following section is for you.
• You will install Postfix as an SMTP server and also install Mutt as an SMTP client to test everything.

sudo apt-get install postfix
#Choose the defaults which works just fine if you simply want to send email from your server over the Internet while **NOT** relaying for other domains.
sudo apt-get install mutt
touch mail.txt
mutt -s "Test PayPal SMTP setup" dirkvanderwalt@gmail.com < mail.txt 

• Refer to the following URL as reference to specify your own choice of SMTP provider
• We can configure the SMTP server that the rd_cake CakePHP application will use by editing two files:
  • To create or modify an SMTP provider definition we edit the /usr/share/nginx/html/cake2/rd_cake/Config/email.php file. Here's a snippet from that file:

 public $default = array(
                'transport' => 'Mail',
                'from' => 'you@localhost',
                //'charset' => 'utf-8',
                //'headerCharset' => 'utf-8',
        );

• To select one of those definitions we in the PayPal Controller we specify it in the usr/share/nginx/html/cake2/rd_cake/Controller/FinPaypalTransactionsController.php file.
• Here we changed the value form smtp to default.

//Around line 321...
App::uses('CakeEmail', 'Network/Email');
$Email = new CakeEmail();
//$Email->config('smtp');
$Email->config('default');
$Email->subject('Your voucher detail');
....

• Now our SMTP configuration for PayPal integration is completed and we can test it out.
• Next we will do the final testing to confirm everything work as intended.

• Most of the transactions in the PayPal Sandbox are with non-existing email addresses.
• To overcome this we override them with a test email address to whom emails will be addressed to.
• Edit the usr/share/nginx/html/cake2/rd_cake/Controller/FinPaypalTransactionsController.php file and look for the following part where you can add the test email of your choice.

 //FIXME replace with real one when going live!!!
 //$payer_email  = $q_r['FinPaypalTransaction']['payer_email'];
 $payer_email    =  'dirkvanderwalt@gmail.com';
 $data           = Configure::read('paypal.'.$item_name.'.'.$item_number.'.'.$option_selection1);

• When we go live we will use the real ones from the PayPal transactions.
