根据国家/地区对特定 Woocommerce 结帐字段的排序优先级

Question

在Woocommerce中，我需要在结账页面设置三个字段的默认排序优先级（排序）：

第一个变化取决于'IT'国家代码的选择：

• 邮政编码 - '优先级' => 91,

另外两个没有条件，我只需要设置默认优先级：

• billing_email - '优先级' => 30,
• billing_phone - '优先级' => 40，

通过直接编辑文件，class-wc-countries.php核心文件如下图，我得到了我需要的。但很明显，每次更新插件时，我都会丢失更改。

现在我正在寻找一个钩子来以干净的方式完成这项工作。

在class-wc-countries.php（第 935 行附近）来自：

IT' => array(
    'postcode' => array(
        'priority' => 65, // <============= HERE
    ),
    'state'    => array(
    'required' => true,
    'label'    => __( 'Province', 'woocommerce' ),
    ),
),

我将“优先级”值从 65 更改为 91：

IT' => array(
    'postcode' => array(
        'priority' => 91, // <============= HERE
    ),
    'state'    => array(
    'required' => true,
    'label'    => __( 'Province', 'woocommerce' ),
    ),
),

并在第 1203 行周围：

  // Add email and phone fields.
  if ( 'billing_' === $type ) {
      $address_fields['billing_phone'] = array(
          'label'        => __( 'Phone', 'woocommerce' ),
          'required'     => true,
          'type'         => 'tel',
          'class'        => array( 'form-row-wide' ),
          'validate'     => array( 'phone' ),
          'autocomplete' => 'tel',
          'priority'     => 100, // <============= HERE
      );
      $address_fields['billing_email'] = array(
          'label'        => __( 'Email address', 'woocommerce' ),
          'required'     => true,
          'type'         => 'email',
          'class'        => array( 'form-row-wide' ),
          'validate'     => array( 'email' ),
          'autocomplete'=>'no'===get_option
              ('woocommerce_registration_generate_username' )
              ? 'email' : 'email username',
          'priority'     => 110, // <============= HERE
       );
    }

我将“优先级”值更改为：

  // Add email and phone fields.
  if ( 'billing_' === $type ) {
      $address_fields['billing_phone'] = array(
          'label'        => __( 'Phone', 'woocommerce' ),
          'required'     => true,
          'type'         => 'tel',
          'class'        => array( 'form-row-wide' ),
          'validate'     => array( 'phone' ),
          'autocomplete' => 'tel',
          'priority'     => 40, // <============= HERE
      );
      $address_fields['billing_email'] = array(
          'label'        => __( 'Email address', 'woocommerce' ),
          'required'     => true,
          'type'         => 'email',
          'class'        => array( 'form-row-wide' ),
          'validate'     => array( 'email' ),
          'autocomplete'=>'no'===get_option
              ('woocommerce_registration_generate_username' )
              ? 'email' : 'email username',
          'priority'     => 30, // <============= HERE
       );
    }

感谢任何帮助。

Answer 1

使用可用的过滤器挂钩，您可以在不覆盖核心文件的情况下进行更改...

第一个改变是用这个钩子（对于“IT”国家代码）：

add_filter('woocommerce_get_country_locale', 'custom__country_locale', 30, 1 );
function wps_select_order_meta_keys( $locale ) {
    $locale['IT']['postcode']['priority'] = 91;
    return $locale;
}

对于第二个更改您还需要更改类。它与您在其他问题的答案中已经拥有的代码相同，但无需删除此行：

if( ! is_account_page() ) return $fields;

代码是：

add_filter(  'woocommerce_billing_fields', 'custom_billing_fields', 20, 1 );
function custom_billing_fields( $fields ) {

    ## ---- 1.  Sort billing email and phone fields ---- ##

    $fields['billing_email']['priority'] = 30;
    $fields['billing_email']['class'] = array('form-row-first');
    $fields['billing_phone']['priority'] = 40;
    $fields['billing_phone']['class'] = array('form-row-last');

    return $fields;
}

因此，如果您从 the code in my other answer 中删除 if( ! is_account_page() ) return $fields;，它也可以在结帐页面上使用（如前所述）...

因此您可以使用（用于帐户和结帐页面）：

add_filter(  'woocommerce_default_address_fields', 'custom_default_address_fields', 20, 1 );
function custom_default_address_fields( $fields ) {

    ## ---- 1.  Remove 'address_2' field ---- ##

    unset($fields['address_2']);

    ## ---- 2.  Sort Address fields ---- ##

    // Set the order (sorting fields) in the array below
    $sorted_fields = array('first_name','last_name','company','address_1','country','postcode','city','state');

    $new_fields = array();
    $priority = 0;

    // Reordering billing and shipping fields
    foreach($sorted_fields as $key_field){
        $priority += 10;

        if( $key_field == 'company' )
            $priority += 20; // keep space for email and phone fields

        $new_fields[$key_field] = $fields[$key_field];
        $new_fields[$key_field]['priority'] = $priority;
    }
    return $new_fields;
}

代码进入您的活动子主题（或活动主题）的 function.php 文件中。经过测试并且可以工作。
