Hi @mikejolley, there are a few changes that have to be made to this code to work. Could you please update whenever you have the time. Here are the updates that need to be done:

1. There should be an argument passed to the constructor like __construct( $instance_id = 0 ) and then in the body of the constructor: $this->instance_id = absint( $instance_id );

2. Also the calculate_shipping method should be with predefined argument as so: public function calculate_shipping( $package = array())

3. If you would like to have option to edit your shipping method from a single settings page, or to see it in the options with the other shipping methods in the shipping zone page you will need to add in the constructor the following code:

$this->supports = array(
         'shipping-zones',//make your shipping method available for the shipping zones
         'settings', //use this for separate settings page
         'instance-settings', //add options for to edit the settings of your shipping method for a single zone
         'instance-settings-modal',
       );

For everyone interest in full working demo, please check here.

I was wondering how to get a shipping method to just appear under zones under the shipping zones section and not as a separate section

The reason I ask is because this shows up in my list of shipping options

And I'd only like the shipping zones options to appear not the UK Flat Rate as well?

Is that possible?

Many thanks, Alordiel.
