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 );
此代码有效，但要隐藏我需要刷新页面的字段。 如何使用 Ajax 隐藏字段？
最佳答案
Update 4 (made on June 2018)
- Added a delay on initialization specifically for Woocommerce 3.4.x.
- Solved a bug when shipping address checkbox is enabled.
- Enhanced lighter and more effective jQuery code.
- Added conditional fields validation
您不需要任何 Ajax 即可实现此目的。第一个功能将使所有必要的结帐字段都不是“必需的”，因为这是能够有条件地显示/隐藏结帐字段所必需的。第二个函数(主要是 jQuery)将根据所选的送货方式显示/隐藏所需的字段。
// Conditional Show hide checkout fields based on chosen shipping methods
add_action( 'wp_footer', 'custom_checkout_field_script' );

$pickpoint = 'wc_custom_shipping_pickpoint';
$required_text = esc_attr__( 'required', 'woocommerce' );
$required_html = '<abbr class="required" title="' . $required_text . '">*</abbr>';
