Woocommerce Adding Multiple shipping methods - wordpress

Question

I used the code below (as provided by woocommerce API) to add custom Shipping Method and it is working but now I want to add another shipping method I tried copy pasting same code with different class name but it doesn't work actually the second method is replacing the first one
I want to know how can I create another Shipping method?
Thank you
function your_shipping_method_init() {
if ( ! class_exists( 'WC_Your_Shipping_Method' ) ) {
class WC_Your_Shipping_Method extends WC_Shipping_Method {
/**
* Constructor for your shipping class
*
* #access public
* #return void
*/
public function __construct() {
$this->id = 'vip_rate'; // Id for your shipping method. Should be uunique.
$this->method_title = __( 'VIP Shipping Rate' ); // Title shown in admin
$this->method_description = __( '$35 flate rate' ); // Description shown in admin
$this->enabled = "yes"; // This can be added as an setting but for this example its forced enabled
$this->title = "VIP Shipping rate"; // This can be added as an setting but for this example its forced.
$this->init();
}
/**
* Init your settings
*
* #access public
* #return void
*/
function init() {
// Load the settings API
$this->init_form_fields(); // This is part of the settings API. Override the method to add your own settings
$this->init_settings(); // This is part of the settings API. Loads settings you previously init.
// Save settings in admin if you have any defined
add_action( 'woocommerce_update_options_shipping_' . $this->id, array( $this, 'process_admin_options' ) );
}
/**
* calculate_shipping function.
*
* #access public
* #param mixed $package
* #return void
*/
public function calculate_shipping( $package ) {
$cost=35;
$rate = array(
'id' => $this->id,
'label' => $this->title,
'cost' => round($cost,2),
'calc_tax' => 'per_item'
);
// Register the rate
$this->add_rate( $rate );
}
}
}
}
add_action( 'woocommerce_shipping_init', 'your_shipping_method_init' );
function add_your_shipping_method( $methods ) {
$methods[] = 'WC_Your_Shipping_Method';
return $methods;
}
add_filter( 'woocommerce_shipping_methods', 'add_your_shipping_method' );

Answer 1

I'm having the same issue , my solution was made a new class who extends from WC_Shipping_Method and keep all the same code there and i made 3 new classes extending the new one , any one with their own ID and mothod type
Its not the best solution but its more legant than duplicate N times the same code of the class

Answer 2

OK I have succeeded in adding another Shipping method by renaming Class name.Previously I may be doing something wrong
However I would like to know if there was some better way of doing it because I have copy pasted whole chunk of code twice , My background is not in OOP however I think it is not the proper way of doing this thing
