根据选择器选择显示自定义结帐字段
Displaying custom checkout fields based on a selector choice
基于这个可行的答案：
在 WooCommerce 结帐页面中，我使用下面的代码创建一些额外的自定义字段并重新排序所有结帐字段。我使用 jQuery 脚本根据选择器选择 show/hide 某些字段。
这是我的新代码：
// Registering external jQuery/JS file
function cfields_scripts() {
/* IMPORTANT NOTE: For a child theme replace get_template_directory_uri() by get_stylesheet_directory_uri()
The external cfields.js file goes in a subfolder "js" of your active child theme or theme.*/
wp_enqueue_script( 'checkout_script', get_template_directory_uri().'/js/cfields.js', array('jquery'), '1.0', true );
}
add_action( 'wp_enqueue_scripts', 'cfields_scripts' );
add_filter( 'woocommerce_checkout_fields', 'custom_checkout_billing_fields' );
function custom_checkout_billing_fields( $fields ) {
// 1. Creating the additional custom billing fields
// The "status" selector
$fields['billing']['billing_status']['type'] = 'select';
$fields['billing']['billing_status']['class'] = array('form-row-wide, status-select');
$fields['billing']['billing_status']['required'] = true;
$fields['billing']['billing_status']['label'] = __('Statut Juridic', 'my_theme_slug');
$fields['billing']['billing_status']['placeholder'] = __('Alege statutul', 'my_theme_slug');
$fields['billing']['billing_status']['options'] = array(
'1' => __( 'Persoana Fizica', '' ),
'2' => __( 'Persoana Juridica', '' )
);
// Customizing 'billing_company' field ['required']
$fields['billing']['billing_company']['required'] = false;
$fields['billing']['billing_company']['class'] = array('form-row-wide', 'status-group2');

$fields['billing']['billing_ib_id']['required'] = false;
$fields['billing']['billing_ib_id']['label'] = __('IBAN', 'my_theme_slug');
$fields['billing']['billing_ib_id']['placeholder'] = __('Adauga IBAN-ul', 'my_theme_slug');
// The "CIF" text field
$fields['billing']['billing_cf_id']['type'] = 'text';
$fields['billing']['billing_cf_id']['class'] = array('form-row-wide', 'status-group2');
$fields['billing']['billing_cf_id']['required'] = false;
$fields['billing']['billing_cf_id']['label'] = __('Cod Fiscal', 'my_theme_slug');
$fields['billing']['billing_cf_id']['placeholder'] = __('Adauga CIF-ul', 'my_theme_slug');
// 3. Ordering the billing fields
$fields_order = array(
'billing_first_name', 'billing_last_name', 'billing_email',
'billing_phone', 'billing_address_1', 'billing_address_2',
'billing_postcode', 'billing_city', 'billing_country',

'billing_company', 'billing_ser_id', 'billing_bt_id',
'billing_ib_id', 'billing_cf_id'
);
foreach($fields_order as $field) $ordered_fields[$field] = $fields['billing'][$field];
$fields['billing'] = $ordered_fields;
// Returning Checkout customized billing fields
return $fields;
}
// Process the checkout
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');
function custom_checkout_field_process() {
// Check if set, if its not set add an error.
if ( ! $_POST['billing_ser_id'] )
wc_add_notice( __( 'Please enter your Serial id.' , 'my_theme_slug' ), 'error' );
if ( ! $_POST['billing_bt_id'] )
wc_add_notice( __( 'Please enter your Serial id.' , 'my_theme_slug' ), 'error' );

wc_add_notice( __( 'Please enter your Serial id.' , 'my_theme_slug' ), 'error' );
if ( ! $_POST['billing_cf_id'] )
wc_add_notice( __( 'Please enter your Serial id.' , 'my_theme_slug' ), 'error' );
}
// Update the order meta with field value
add_action( 'woocommerce_checkout_update_order_meta', 'custom_checkout_field_update_order_meta' );
function custom_checkout_field_update_order_meta( $order_id ) {

}
// Display field value on the order edit page
add_action( 'woocommerce_admin_order_data_after_billing_address', 'custom_checkout_field_display_admin_order_meta', 10, 1 );
function custom_checkout_field_display_admin_order_meta($order){
echo '<p><strong>'.__('My serial identification').':</strong> ' . get_post_meta( $order->id, 'billing_ser_id', true ) . '</p>';

echo '<p><strong>'.__('My serial identification').':</strong> ' . get_post_meta( $order->id, 'billing_cf_id', true ) . '</p>';
}
Javascriptcfields.js代码(不完整外部文件):
// This file named "cfields.js" goes in a subfolder "js" of your active child theme or theme
jQuery(document).ready(function($){
$('#billing_company_field').hide(function(){
$(this).removeClass("validate-required");
});
$('#billing_ser_id_field').hide(function(){
$(this).removeClass("validate-required");
});
$("#billing_number_id_field").addClass("validate-required");
$("#billing_status").change(function(){
if($("#billing_status option:selected").val() == "2"){
$('#billing_company_field').show(function(){
$(this).addClass("validate-required");
});
$('#billing_ser_id_field').show(function(){
$(this).addClass("validate-required");
});
} else if($("#billing_status option:selected").val() == "1"){
$('#billing_company_field').hide(function(){
$(this).removeClass("validate-required");
});
$('#billing_ser_id_field').hide(function(){
$(this).removeClass("validate-required");
});
}
});
});
因为我有一些额外的字段，我现在需要的是 billing_status 选择器打开时：
- Persoana Fizica 选项值 （个人）：仅显示
billing_serial自定义字段。
Persoana Juridica 选项值 （公司），还会出现 4 个字段：
billing_company 现有字段（首先，在billing_serial之前）billing_registration_id自定义字段（在这两种情况下始终显示该字段）billing_bank_id自定义字段billing_bankno_id自定义字段billing_cif_id自定义字段
我还想在 Thankyou 订单接收页面和电子邮件通知中显示此数据。
我还没有找到让它工作的方法。我怎样才能让它正常工作？
提前致谢。
UPDATE
由于您添加了其他海关字段并进行了一些更改，您会在下面找到使其正常工作所需的代码。 这正在成为一个真正的发展，不应该在这里问。我总是努力完成我已经开始的事情，所以我回答它。
The most difficult thing here is to avoid WooCommerce alert notice on hidden required fields when selector is on Individual. For this you are obliged (with the help of jQuery) to imput a "no" value in that hidden fields.
So when the order will be submitted, you will get all the custom fields values in the order meta data (for Individual your hidden fields will have a "no" value. It's the only possible way.
But as we can process the displayed data and even update it afterwards, this is not a problem, as you will see…

因为我有一些额外的字段，我现在需要的是 billing_status 选择器打开时：
- Persoana Fizica 选项值 （个人）：仅显示
billing_serial自定义字段。 Persoana Juridica 选项值 （公司），还会出现 4 个字段：
billing_company现有字段（首先，在billing_serial之前）billing_registration_id自定义字段（在这两种情况下始终显示该字段）billing_bank_id自定义字段billing_bankno_id自定义字段billing_cif_id自定义字段
我还想在 Thankyou 订单接收页面和电子邮件通知中显示此数据。
我还没有找到让它工作的方法。我怎样才能让它正常工作？
提前致谢。
UPDATE
由于您添加了其他海关字段并进行了一些更改，您会在下面找到使其正常工作所需的代码。 这正在成为一个真正的发展，不应该在这里问。我总是努力完成我已经开始的事情，所以我回答它。
The most difficult thing here is to avoid WooCommerce alert notice on hidden required fields when selector is on
Individual. For this you are obliged (with the help of jQuery) to imput a "no" value in that hidden fields.So when the order will be submitted, you will get all the custom fields values in the order meta data (for
Individualyour hidden fields will have a"no"value. It's the only possible way.
But as we can process the displayed data and even update it afterwards, this is not a problem, as you will see…
