woocommerce shipping method for specific city based on weight - php

Question

How to make shipping method based on weight for specific city?
For example, I want to take the postage for city "A" for $1 per kg.
Here is the code of plugin I made:
public function calculate_shipping( $package ) {
$rate = array(
'id' => $this->id,
'label' => $this->title,
'cost' => '10.99',
'calc_tax' => 'per_item'
);
// Register the rate
$this->add_rate( $rate );
}
Full code:

/**

if ( in_array( 'woocommerce/woocommerce.php', apply_filters( 'active_plugins', get_option( 'active_plugins' ) ) ) ) {
function trucking_shipping_init() {
if ( ! class_exists( 'WC_Your_Shipping_Method' ) ) {
class WC_trucking_shipping_Method extends WC_Shipping_Method {
/**
* Constructor for your shipping class
*
* #access public
* #return void
*/
public function __construct() {
$this->id = 'trucking_shipping_method'; // Id for your shipping method. Should be uunique.
$this->method_title = __( 'JNE TRUCKING' ); // Title shown in admin
$this->method_description = __( 'Pengiriman dengan truck JNE' ); // Description shown in admin
$this->enabled = "yes"; // This can be added as an setting but for this example its forced enabled
$this->title = "JNE TRUCKING"; // 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 ) {
$rate = array(
'id' => $this->id,
'label' => $this->title,
'cost' => '10.99',
'calc_tax' => 'per_item'
);
// Register the rate
$this->add_rate( $rate );
}
}
}
}
add_action( 'woocommerce_shipping_init', 'trucking_shipping_init' );
function add_trucking_shipping_method( $methods ) {
$methods['trucking_shipping_method'] = 'WC_trucking_shipping_Method';
return $methods;
}
add_filter( 'woocommerce_shipping_methods', 'add_trucking_shipping_method' );
}
The problem is in calculate_shipping, I don't know how to do what I want.

This is not really a code question, rather a 'how do I use WooCommerce' question. What you are looking for is functionality Automattic deliberately removed from WooCommerce so that they could charge for it, look here for the plugin.
If you are frugal and reduce your product weights down to a specific set, then all you really need is flat rate shipping assigned to postal code defined shipping zones, mixed with shipping classes and boom no programming ever needed.
