Other releases

Release 0.1.0 - 23/04/2007

• You first need to download the PHP Paypal's API: SOAP Interface here

• The sfPaypalDirect constructor takes the path where you install Paypal's API. I don't recommend putting it on lib since you don't want it to be automatically loaded on every page view.

• To use the Direct Payment method you can do something like the following:

  $this->error = $this->charge_cc('Membership fee', '19.95'); if ( $this->error == * ) { // Save information and redirect to another action }

  // Else display $error on template

  private function charge_cc($desc, $total) { $error = *; $cc = new sfPaypalDirect(sfConfig::get('sf_data_dir').DIRECTORY_SEPARATOR.'PayPal');

      // Setup API's credentials
  $cc->setUserName(sfConfig::get('mod_registration_paypal_username'));
  $cc->setPassword(sfConfig::get('mod_registration_paypal_password'));
  $cc->setSignature(sfConfig::get('mod_registration_paypal_signature'));
  $cc->setTestMode(sfConfig::get('mod_registration_paypal_test'));
  
  $cc->setTransactionTotal($total);
  $cc->setTransactionDescription($desc);
  
  $cc->setBillingFirstName($this->getRequestParameter('firstname'));
  $cc->setBillingLastName($this->getRequestParameter('lastname'));
  $cc->setBillingStreet1($this->getRequestParameter('address'));
  $cc->setBillingStreet2($this->getRequestParameter('address2'));
  $cc->setBillingCity($this->getRequestParameter('city'));
  $cc->setBillingState($this->getRequestParameter('state'));
  $cc->setBillingZip($this->getRequestParameter('zip'));
  
  $cc->setCardType($this->getRequestParameter('cctype'));
  $cc->setCardNumber($this->getRequestParameter('cc'));
  $cc->setCardVerificationNumber($this->getRequestParameter('ccv'));
  $cc->setCardExpirationMonth($this->getRequestParameter('expmonth'));
  $cc->setCardExpirationYear($this->getRequestParameter('expyear'));
  $cc->setBuyerIP($_SERVER['REMOTE_ADDR']);
  
  if ( !$cc->chargeDirect() )
  {
      $error = $cc->getErrorString();
  }
  return $error;
  

  }

• To implement Express Checkout, it can be a little trickier. First you need to take the user to Paypal's webpage so they can do their payments there. Then Paypal will send the user to a specified URL if the payment was successful or to a different URL if the user cancelled the payment. The following illustrates how to use this plugin on a module called registration:

      $cc = new sfPaypalDirect(sfConfig::get('sf_data_dir').DIRECTORY_SEPARATOR.'PayPal');
  
      // Setup API's credentials
      $cc->setUserName(sfConfig::get('mod_registration_paypal_username'));
      $cc->setPassword(sfConfig::get('mod_registration_paypal_password'));
      $cc->setSignature(sfConfig::get('mod_registration_paypal_signature'));
      $cc->setTestMode(sfConfig::get('mod_registration_paypal_test'));
  
      sfLoader::loadHelpers(array('Url'));
      // URL to go to if the cancel payment
      $cc->setCancelURL(url_for('registration/cancelpaypal', true));
  
      // URL to verify or charge transaction
      $cc->setReturnURL(url_for('registration/chargepaypal', true));
  
      $cc->setTransactionTotal('39.95');
      $cc->setTransactionDescription('Registration');
  
      // Get a Paypal URL to go to
      $goto = $cc->GetExpressUrl();
      if ( $goto )
      {
              $this->redirect($goto);
      }
      else
      {
              return $this->renderText('Error: ' . $cc->getErrorString());
      }
  

• These are sample actions for a cancel URL and return URL

  // Cancel action public function executeCancelpaypal() { return $this->renderText('Oh no!'); }

  // Payment was successful, try to charge public function executeChargepaypal() { $cc = new sfPaypalDirect(sfConfig::get('sf_data_dir').DIRECTORY_SEPARATOR.'PayPal');

      // Setup API's credentials
      $cc->setUserName(sfConfig::get('mod_registration_paypal_username'));
      $cc->setPassword(sfConfig::get('mod_registration_paypal_password'));
      $cc->setSignature(sfConfig::get('mod_registration_paypal_signature'));
      $cc->setTestMode(sfConfig::get('mod_registration_paypal_test'));
  
      $cc->setTransactionTotal('39.95');
      $cc->setTransactionDescription('Registration');
  
      if ( $cc->chargeExpressCheckout($this->getRequestParameter('token')) )
      {
              return $this->renderText('Charged successfully');
      }
      else
      {
              return $this->renderText('Error: ' . $cc->getErrorString());
      }
  

  }
