Action "llms_user_enrollment_deleted" error

[saracomin96]

Reproduction Steps

hi, i found this action that fires after the user is deleted from a course. I found a problem though, even if I use it without any function inside it, such as this:

function llms_user_enrollment_deleted_function($user_id, $product_id, $enrollment_trigger) {
}

add_action ('llms_user_enrollment_deleted', 'llms_user_enrollment_deleted_function');

In the course settings when I try to remove a user it remains pending like this:

When I refresh the page the user is deleted, but he shouldn't do that

Expected Behavior

user removals without infinite pending and function starting correctly

Actual Behavior

Infinite loading and internal functions are not performed

complete function
function llms_user_enrollment_deleted_function($user_id, $product_id, $enrollment_trigger) {

$contactApi = FluentCrmApi('contacts');
$user_info = get_userdata($user_id);
$emailAddress = $user_info->user_email;
$post_type = get_post_type( $product_id );

if($post_type == 'course' && metadata_exists( 'post', $product_id, 'wpcf-id_lista' )) {

$id_lista = get_post_meta($product_id, 'wpcf-id_lista', true);

if(!empty($id_lista)){

$contact = $contactApi->getContact($emailAddress);
$listIds = [$id_lista]; // 5 is the list ID
$contact->detachLists($listIds);
//return true;
}

}

return true;
}

add_action( 'llms_user_enrollment_deleted', 'llms_user_enrollment_deleted_function' );

Hi Sara,
thanks for reporting this.

Looks like you're using add_action() the wrong way.
You defined a callback that requires 3 parameters:
function llms_user_enrollment_deleted_function($user_id, $product_id, $enrollment_trigger) {
But you're passing only one parameter:
add_action ('llms_user_enrollment_deleted', 'llms_user_enrollment_deleted_function');

The latter should be:
add_action ('llms_user_enrollment_deleted', 'llms_user_enrollment_deleted_function', 10, 3);
Where 10 is the default priority, and 3 the number of parameters passed to the callback.
See: https://developer.wordpress.org/plugins/hooks/actions/

Also if enabling the WordPress debug (debug log even better), will help you troubleshooting PHP errors in the code.
See: https://lifterlms.com/docs/how-to-debug-a-white-screen/#log

Hope this helps.
