WooCommerce |设置计费字段值 [英] WooCommerce | Set billing field value

问题描述

我想在用户第一次购买之前将结帐帐单字段的值预填充到用户的数据库存储值.

I want to pre-populate the values for the checkout's billing fields to the DB stored values of the user before his first purchase.

我尝试了以下代码:

add_filter( 'woocommerce_checkout_fields' , function ( $fields ) {
    $fields['billing']['billing_first_name']['placeholder'] = 'First Name';
    $fields['billing']['billing_first_name']['default'] = wp_get_current_user()->user_firstname;
    return $fields;
});

我在 其他帖子.占位符效果很好，但值不行.

I've read about this solution in an other post. Placeholder works great, but the value doesn't.

此外，WooCommerce 文档(第 1 课)没有说明数组值 'default' 的任何内容

Also, the WooCommerce Doc (Lesson 1) doesn't say about anything the array value 'default'

推荐答案

你已经很接近了.这对我有用.我不知道是否有必要，但我使用了一个命名函数，如果用户存在，则只获取 user_firstname 属性.

You're pretty close. This worked for me. I don't know if it was necessary, but I used a named function and only get the user_firstname property if the user exists.

add_filter( 'woocommerce_checkout_fields' , 'kia_checkout_field_defaults', 20 );
function kia_checkout_field_defaults( $fields ) {
    $user = wp_get_current_user();
    $first_name = $user ? $user->user_firstname : '';
    $fields['billing']['billing_first_name']['placeholder'] = 'First Name';
    $fields['billing']['billing_first_name']['default'] = $first_name;
    return $fields;
}
