Paypal_Lib + Monthly Subscription

[eluser]pickupman[/eluser]
I just recently did something similar on a project. I added to the Paypal_lib a add_subscription() method to handle the extra fields like recurring period and such.

Code:

/**
      * Add fields for a subscription button
      * Defaults
      * a3 = $10
      * p3 = 12
      * t3 = months
      * sra = 1 reattempt failed payment
      * @param array of key=>values for fields
      * @return bool
      */
     public function add_subscription( $options = array() ){
        
        //Merge default values with values passed to function
        $options = array_merge( array('a3' => '10',
                                      'p3' => '12',
                                      't3' => 'M',
                                      'sra'  => TRUE,
                                      'custom' => rand()
                                    ), $options);
                                    
        foreach ($options as $key => $value) {
            $this->add_field($key, $value);
        }
       return TRUE;
        
     }

I still use add_field for business_name. I created a class property for paypal command. Then I can pass _xclick or subscription for the form type.
