Add option to customize the "sent from" and "reply to" addresses on emails sent by the SendEmail step

[andergmartins]

Some users want to use different "sent from - name and email" and "reply to" addresses on emails sent by workflows. We could have a new panel with specific settings in the SendEmail step to configure that.

Here is the custom code I sent to the customer, until we implement this new feature. Please, not this only works for Future 4.7+.

add_action('publishpressfuture_workflow_engine_execute_step', function ($step) {
    if ($step['node']['data']['name'] !== 'action/core.send-email') {
        return;
    }

    add_filter('wp_mail', 'mycustom_change_reply_to_address');
    add_filter('wp_mail_from_name', 'mycustom_change_from_name');
    add_filter('wp_mail_from', 'mycustom_change_from_address');
});

function mycustom_change_reply_to_address($args) {
    // Remove any existing Reply-To header
    $args['headers'] = preg_replace('/Reply-To:.*?\n/i', '', $args['headers']);

    // Add the new Reply-To header
    $args['headers'] = $args['headers'] . "\nReply-To: custom-reply-to@test.com";

    return $args;
}

function mycustom_change_from_name($name) {
    return 'Custom From Name';
}

function mycustom_change_from_address($address) {
    return 'custom-from@test.com';
}
