如何在woocommerce中添加自定义运费？

Question

我想使用woocommerce中的代码添加运费.这是我的要求.

如果我的运输国家是澳大利亚,则运费不同,澳大利亚境外也不同.现在,如果我的运输国家是澳大利亚和

1. if order value is < 100, then shipping charge is $100 
2. if order value is > 100, then shipping charge is $0.

如果我的运输国家在澳大利亚境外

 1. if order value is < 500, then shipping charge is $60
 2. if order value is > 500 and < 1000, then shipping charge is $50
 3. if order value is > 1000, then shipping charge is $0

那么,当用户从结帐页面更改送货国家时,如何根据我的上述要求添加自定义运费.我尝试下面的代码,但它只适用于订单价值,如何在自定义插件中的下面代码中添加送货国家/地区.

class WC_Your_Shipping_Method extends WC_Shipping_Method {
    public function calculate_shipping( $package ) {
    global $woocommerce;
        if($woocommerce->cart->subtotal > 5000) {
            $cost = 30; 
        }else{
            $cost = 3000;
      }
}
$rate = array(
    'id' => $this->id,
    'label' => $this->title,
    'cost' => $cost,
    'calc_tax' => 'per_order'
);

// Register the rate
$this->add_rate( $rate );

}

最好为可以使用钩子的运费制作自定义插件.
首先在自定义插件中扩展'WC_Your_Shipping_Method'类,然后创建如下函数:

public function calculate_shipping( $package ) {
    session_start();
    global $woocommerce;

    $carttotal = $woocommerce->cart->subtotal;
    $country = $_POST['s_country']; //$package['destination']['country'];

    if($country == 'AU')
    {
        if($carttotal > 100){
            $cost = 5;
        }else{
            $cost = 10;//10.00;
        }
    }
    else
    {
        if($carttotal < 500){
            $cost = 60;//60.00;
        }else if($carttotal >= 500 && $carttotal <= 1000){
            $cost = 50;//50.00;
        }else if($carttotal > 1000){
            $cost = 0;
        }
    }

    $rate = array(
        'id' => $this->id,
        'label' => 'Shipping',
        'cost' => $cost,
        'calc_tax' => 'per_order'
    );

    // Register the rate
    $this->add_rate( $rate );
}
