我正在尝试根据送货方式隐藏结帐字段。
function premove_billing_checkout_fields($fields) {
global $woocommerce;
$chosen_methods = WC()->session->get( 'chosen_shipping_methods' );
$chosen_shipping = $chosen_methods[0];
if( $chosen_shipping === 'local_pickup:20' ) {
unset($fields['billing']['billing_postcode']);
unset($fields['billing']['billing_state']);
unset($fields['billing']['billing_country']);
}
if( $chosen_shipping === 'wc_custom_shipping_pickpoint' ) {
unset($fields['billing']['billing_postcode']);
unset($fields['billing']['billing_address_1']);
unset($fields['billing']['billing_state']);
}
return $fields;
}
add_filter('woocommerce_checkout_fields',
'premove_billing_checkout_fields', 990 );
此代码正常运行，但隐藏了刷新页面所需的字段。 如何使用Ajax隐藏字段？
答案 0 :(得分：7)
更新4 （2018年6月制作）
- 特别为Woocommerce 3.4.x添加了初始化延迟。
- 启用了送货地址复选框时解决了一个错误。
- 增强更轻，更有效的jQuery代码。
- 增加了条件字段验证
您不需要任何Ajax来实现此目的。第一个函数将使所有必要的结帐字段不是“必需”，因为这是有条件地显示/隐藏结帐字段所必需的。第二个功能（主要是jQuery）将根据所选的送货方式显示/隐藏您想要的字段。
