WooCommerce - 签出不同人自定义状态的条件字段

我需要修改 woocommerce 网站的结账流程。该过程由人员的状态决定，可能是以下之一：
- 'legal entity'
- 'individual'

我需要一个选择器'User status' （或单选按钮），就在“billing_first_name”和“billing_last_name”之后。

选择器应该这样工作：

1. If 'legal entity' is selected, it should display 3 fields:
   • '电话号码'
   • 'email'
   • '序列号'
2. If 'individual' is selected, it should display 3 other fields:
   • '自定义字段1'
   • '自定义字段2'
   • '自定义字段3'

我尝试了 WooCommerce Checkout Manager 和另一个插件，但问题是我无法制定匹配条件。

我怎样才能实现这个目标？

Thanks.

对于 WooCommerce 3+(update):

Since WooCommerce 3.0 结账字段发生了一些变化，因此不可能像以前那样对字段进行重新排序。

有一个新的'优先事项'争论处理字段顺序，也适用于结帐字段和我的帐户字段。

下面我只是更新与订购字段相关的部分：

## 3. Ordering the billing fields

// Set the order of the fields
$billing_fields_new_order = array(
    'billing_first_name', 'billing_last_name', 'billing_status',
    'billing_email',      'billing_phone',     'billing_serial_id',
    'billing_custom1',    'billing_custom2',   'billing_custom3',
    'billing_company',    'billing_address_1', 'billing_address_2',
    'billing_postcode',   'billing_city',      'billing_country',
);

$count = 0;
$priority = 10;

// Updating the 'priority' argument
foreach($billing_fields_new_order as $field_name){
    $count++;
    $fields['billing'][$field_name]['priority'] = $count * $priority;
}

// END: returning the customized checkout fields
return $fields;

原答案：

你需要使用woocommerce_checkout_fields钩。然后首先创建新字段。自定义一些字段类后。完成后重新排序字段以满足您的愿望。

这是代码：

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'] = __('User status', 'my_theme_slug');
    $fields['billing']['billing_status']['placeholder'] = __('Chose an option', 'my_theme_slug');
    $fields['billing']['billing_status']['options'] = array(
        '' => 'Chose an option',
        '1' => 'Legal entity',
        '2' => 'Individual'
    );

    // The "Serial ID" text field
    $fields['billing']['billing_serial_id']['type'] = 'text';
    $fields['billing']['billing_serial_id']['class'] = array('form-row-wide', 'status-group1');
    $fields['billing']['billing_serial_id']['required'] = true;
    $fields['billing']['billing_serial_id']['label'] = __('Serial ID', 'my_theme_slug');
    $fields['billing']['billing_serial_id']['placeholder'] = __('Enter your Serial ID', 'my_theme_slug');

    // The "Custom 1" text field
    $fields['billing']['billing_custom1']['type'] = 'text';
    $fields['billing']['billing_custom1']['class'] = array('form-row-wide', 'status-group2');
    $fields['billing']['billing_custom1']['required'] = true;
    $fields['billing']['billing_custom1']['label'] = __('Custom name 1', 'my_theme_slug');
    $fields['billing']['billing_custom1']['placeholder'] = __('Enter your custom1', 'my_theme_slug');

    // The "Custom 2" text field
    $fields['billing']['billing_custom2']['type'] = 'text';
    $fields['billing']['billing_custom2']['class'] = array('form-row-wide', 'status-group2');
    $fields['billing']['billing_custom2']['required'] = true;
    $fields['billing']['billing_custom2']['label'] = __('Custom name 2', 'my_theme_slug');
    $fields['billing']['billing_custom2']['placeholder'] = __('Enter your custom2', 'my_theme_slug');

    // The "Custom 3" text field
    $fields['billing']['billing_custom3']['type'] = 'text';
    $fields['billing']['billing_custom3']['class'] = array('form-row-wide', 'status-group2');
    $fields['billing']['billing_custom3']['required'] = true;
    $fields['billing']['billing_custom3']['label'] = __('Custom name 3', 'my_theme_slug');
    $fields['billing']['billing_custom3']['placeholder'] = __('Enter your custom3', 'my_theme_slug');


// 2. Customizing 'billing_email' and 'billing_phone' fields ['class']

    $fields['billing']['billing_email']['class'] = array('form-row-first', 'status-group1');
    $fields['billing']['billing_phone']['class'] = array('form-row-last', 'status-group1');


// 3. Ordering the billing fields

    $fields_order = array(
        'billing_first_name', 'billing_last_name', 'billing_status',
        'billing_email',      'billing_phone',     'billing_serial_id',
        'billing_custom1',    'billing_custom2',   'billing_custom3',
        'billing_company',    'billing_address_1', 'billing_address_2',
        'billing_postcode',   'billing_city',      'billing_country',
    );
    foreach($fields_order as $field) $ordered_fields[$field] = $fields['billing'][$field];

    $fields['billing'] = $ordered_fields;
    

// Returning Checkout customized billing fields

    return $fields;

}

当然，这会出现在您的活动子主题或主题的 function.php 文件中

该代码已经过测试并且功能齐全。

现在有了这段代码，您可以提出一个问题来处理这个问题的“条件”部分（正如我在评论中告诉您的那样）......
