Php 签出字段-将帐单地址设置为帐单地址1上方的帐单地址2

在WooCommerce结帐字段中，我试图在结帐表单上使账单地址2位于账单地址1之上

因此，与其说是：

Street Address
Apartment

我希望：

Apartment
Street Address

请注意，我使用的主题是Avada

我怎样才能做到这一点

谢谢。

更新（与您的评论相关）.

这里您有一个附加功能，从Address1字段中删除“Address”文本标签，并将其设置为Address2字段，使该字段（可选）成为必需字段，并稍微更改占位符……我还有另一个解决方案（见下面的代码）

代码如下：

add_filter( 'woocommerce_checkout_fields', 'custom_billing_fields_order' );
function custom_billing_fields_order( $fields ) {

    // 1. Customizing address_1 and address_2 fields
    $fields['billing']['billing_address_1']['label'] = ''; // Removing the label from Adress1
    $fields['billing']['billing_address_2']['label'] = __('Address', 'theme_domain');
    $fields['billing']['billing_address_2']['required'] = true; // Making Address 2 field required
    $fields['billing']['billing_address_2']['placeholder'] = __('Apartment, suite, unit etc...', 'woocommerce');

    // 2. Custom ordering the billing fields array (toggling address_1 with address_2)
    $custom_fields_order = array(
        'billing_first_name', 'billing_last_name',
        'billing_company',
        'billing_email',      'billing_phone',
        'billing_country',
        'billing_address_2',  'billing_address_1',  ##  <== HERE, changed order
        'billing_postcode',   'billing_city'
    );

    foreach($custom_fields_order as $field)
        $new_ordered_fields[$field] = $fields['billing'][$field];

    // Replacing original fields order by the custom one
    $fields['billing'] = $new_ordered_fields;


    // Returning Checkout customized billing fields order
    return $fields;
}

代码位于活动子主题（或主题）的function.php文件或任何插件文件中

代码经过测试并正常工作

检查我之前试过，这是我的第一直觉，但这只是发生了@巴里汉伯里：我必须对此做一点更新……我会在发布时通知你ready@BarryHanbury我已经更新了我的答案…它按预期工作…当我这样做时，我的状态字段消失，行标记混乱。

add_filter( 'woocommerce_checkout_fields', 'custom_billing_fields_placeholders' );
function custom_billing_fields_placeholders( $fields ) {

    // 1. Customizing address_1 and address_2 fields
    $fields['billing']['billing_address_1']['placeholder'] = __('Apartment, suite, unit etc...', 'woocommerce');
    $fields['billing']['billing_address_2']['required'] = true; // Making Address 2 field required
    $fields['billing']['billing_address_2']['placeholder'] = __('Street address', 'woocommerce');

    // Returning Checkout customized billing fields
    return $fields;
}
