Thank you Franky for the hint.

But again as I’m not a programmer I’m struggling to find a solution …

What I found is a description to the MailChimp API that shows a subscription call I think…

https://apidocs.mailchimp.com/api/2.0/lists/subscribe.php

Hello Franky,

I absolutely understand!

May I just ask two questions to not run into a death end please?

1) Am I on a good way with this?

add_action('eme_insert_rsvp_action', 'my_eme_mailchimpsubscription',20,1);

/**
 * Custom function to subscribe to the newsletter
 */

function my_eme_mailchimpsubscription($booking) {
	global $wpdb;
	$bookings_table = $wpdb->prefix.BOOKINGS_TBNAME;

	$event_id = $booking['event_id'];
	$booking_id = $booking['booking_id'];
	$answers = eme_get_answers($booking_id);
  	$newsletter = "";
 
    foreach ($answers as $answer) {
       if ($answer['field_name'] == "Newsletter") {
            $newsletter = $answer['answer'];
       }
    }
  
    if ($newsletter == "Subscribe") {

	  //do subscription
   
    }
   
	return;
}

2) Can I have multiple actions?

add_action(’eme_insert_rsvp_action’, ‘my_eme_coupons’,20,1);
add_action(’eme_insert_rsvp_action’, ‘my_eme_mailchimpsubscription’,20,1);

Do I have to modify something?

Many thanks in advance.

Cheers
JK

Hi Franky,

I’m sorry just another question…

$person = eme_get_person($booking['person_id']);

How do I get the Firstname, Lastname and Emailaddress out of $person into a variable?

Many thanks for any direction.

Cheers
JK

But I think it has to be:

    $person = eme_get_person($booking['person_id']); 
    $subscribeemail = $person['email'];
    $subscribelname = $person['lastname'];
    $subscribefname = $person['firstname'];

Cool 😀

I now have installed a small api wrapper (https://github.com/drewm/mailchimp-api/) for MailChimp.

And adjusted my code and decided to do as you said adding all into a single action…

/**
 * Add a hook for the Events Made Easy system to allow for coupon codes
 */
add_action('eme_insert_rsvp_action', 'my_eme_custom_stuff',20,1);

/**
 * Custom function to calculate coupon code discounts for events
 */

function my_eme_custom_stuff($booking) {

    include('/myurl/wp-content/uploads/MailChimp.php');
  
    global $wpdb;
	$bookings_table = $wpdb->prefix.BOOKINGS_TBNAME;
	$discount = 10;
    $dealprice = 89; 
	$where = array();
	$fields = array();

  
	// Grab the coupon code from the extra answers
	$event_id = $booking['event_id'];
	$booking_id = $booking['booking_id'];
    $person = eme_get_person($booking['person_id']); 
    $answers = eme_get_answers($booking_id);
    $newsletter = "";
	$coupon = "";
  
    foreach ($answers as $answer) {
       if ($answer['field_name'] == "Coupon") {
             $coupon = $answer['answer'];
          } else if ($answer['field_name'] == "Newsletter") {
    		 $newsletter = $answer['answer'];
 	  }
    }
  
  
	// As long as the coupon code isn't empty, look for matches
    // make the coupon code CAPITALS
    $coupon = strtoupper($coupon);
	if ($coupon == "COUNPON10") {
		// If coupon code used, apply the appropriate price change
		$price = $booking['booking_price'] - ( $booking['booking_price'] * ($discount / 100));
			
		$fields['booking_price'] = $price;
		$where['booking_id'] = $booking['booking_id'];
		$wpdb->update($bookings_table, $fields, $where);
	} else if ($coupon == "NEWSLETTER2015" || $coupon == "CAMPAIN2015") {
		// If coupon code used, apply the appropriate price change
		$price = $dealprice;
			
		$fields['booking_price'] = $price;
		$where['booking_id'] = $booking['booking_id'];
		$wpdb->update($bookings_table, $fields, $where);
	}
 
  
  // Subscription to MailChimp
   
   	if ($newsletter == "Ich möchte den Sensorgrafie Newsletter erhalten.") {

        
        $MailChimp = new \Drewm\MailChimp('MYAPIREF-us10');
  
        // Grab if subscription is asked from the extra answers
      
        $result = $MailChimp->call('lists/subscribe', array(
                'id'                => 'MYLISTID',
                'email'             => array('email'=> $person['email']),
                'merge_vars'        => array('FNAME'=> $person['firstname'], 'LNAME'=> $person['lastname']),
                'double_optin'      => false,
                'update_existing'   => true,
                'replace_interests' => false,
                'send_welcome'      => true,
            ));  

    }  
	

	return;
}

Just to contribute if anybody likes to add the service as well 😉

Yes, it is, just forgot to delete this in the example…
