Access to programmatically added merge_vars on successful subscription

Hey Oejabeja,

In terms of code, the actual subscribe request is pretty much decoupled form the form itself (for easier unit testings, better decoupling, law of demeter etc..). What exactly are you trying to do? Do you want to hook into a successful form submissions or do you want to hook into a successful sign-up request?

We’ll think of a way to make it possible! ??

What I was trying to do was, inserting into the database a woocommerce coupon with a programmatically generated id, if the sign-up request was successful (to avoid creating coupons for unsuccesful requests).

I could probably work my way around this by insert my coupon id as a hidden field in the form, to have access to it on mc4wp_form_success.

But whatever I do it will leave lots of loose threads so I may end up purchasing a premium plugin to do this task.

I would love to see a plugin that fully integrates woocommerce coupon functionality with Mailchimp for bulk creating coupons for all subscriptors, but not even premium plugins seem to do this well. It must be harder than it seems.

Hi Ovejabeja,

Suggestion noted – hopefully we’ll get to it one day. For now, I would tackle this in the following way.

1. Update the plugin to version 3.0.4
2. Use the mc4wp_form_data filter to add your own data to the form. Use the same key as the name of your list-field. The plugin will automatically strip off the field for lists not having a field with that name later on.
3. Hook into mc4wp_form_subscribed to store the coupon, as that hook only runs for successful sign-ups. You can access it from $form->data at that point.

add_action( 'mc4wp_form_subscribed', function( $form ) {
   your_store_coupon_code_function( $form->data['COUPON'] );
});

Hope that helps. If not, let me know!

It’s working nicely, thanks!
