Question

我已经建立了我的第一个发货方法插件，基于统一费率和一些额外的字段。

我做了以下事情： 1.安装并激活插件 2.向英国区域添加了2个运输方式实例

我可以在发货部分的顶部子菜单中看到，在标有“UK Flat Rate”的菜单中似乎有某种“默认”运输插件实例

我想知道是否有办法删除它，并且只有插件才能在发货区部分工作。

我问的原因是，在结帐时如果我输入英国地址，我会看到定义了2种英国方法，然后在它们下方，还有一个英国统一费率单选按钮，我试图摆脱它。它显示基于子节中输入的值的默认值。

插件中是否有设置我缺少强制执行该方法仅基于区域？

Answer 1

原来我需要添加过滤器以删除该部分以及该方法的第一个实例，如此

woocommerce_shipping_option_remove( $section ) {
    unset($section['uk_flat_rate']);
    return $section;
}

add_filter( 'woocommerce_get_sections_shipping', 'woocommerce_shipping_option_remove' ,1 );
function woocommerce_shipping_remove_method( $rates ) 
{
    unset($rates['uk_flat_rate:1']);
    return $rates;
}

add_filter（＆＃39; woocommerce_package_rates＆＃39;，＆＃39; woocommerce_shipping_remove_method＆＃39;，100）; } }
