在WooCommerce中添加隐藏的结帐字段？ [英] Adding a hidden checkout field in WooCommerce?

问题描述

我想包含指向通过WooCommerce提交结帐表格的当前用户的个人资料的链接。

I want to include a link to a profile of the current user who submitted a checkout form through WooCommerce.

也就是说，自动放置当前用户的作者链接在隐藏字段中是这样的： example.com/author/username

That is, to place automatically a current user’s author link like this in the hidden field: example.com/author/username

我想添加一个结帐表单中的隐藏字段。因此，要获取链接，我会这样写：

I want to achieve this by adding a hidden field in checkout form. So to get a link I would write something likes this:

<?php

$currentUser = get_current_user_id();

$user = get_user_by( 'id', $currentUser );

$userUrl = get_bloginfo( 'home' ) . '/author/' . $user->user_login;

echo $userUrl;
?>

我的问题是如何在结帐表单中创建这种类型的隐藏字段？

My question is how can I create this type of hidden field in checkout form?

推荐答案

在 woocommerce_after_order_notes 动作挂钩中附加了自定义功能，您还可以使用此用户作者链接直接输出一个隐藏字段作为隐藏值，当客户下订单时，该字段将与所有结帐字段同时提交。

With a custom function hooked in woocommerce_after_order_notes action hook, you can also directly output a hidden field with this user "author link" as a hidden value, that will be submitted at the same time with all checkout fields when customer will place the order.

这是代码：

add_action( 'woocommerce_after_order_notes', 'my_custom_checkout_hidden_field', 10, 1 );
function my_custom_checkout_hidden_field( $checkout ) {

    // Get an instance of the current user object
    $user = wp_get_current_user();

    // The user link
    $user_link = home_url( '/author/' . $user->user_login );

    // Output the hidden link
    echo '<div id="user_link_hidden_checkout_field">
            <input type="hidden" class="input-hidden" name="user_link" id="user_link" value="' . $user_link . '">
    </div>';
}

然后，您需要按以下方式保存此隐藏字段：

Then you will need to save this hidden field in the order, this way:

add_action( 'woocommerce_checkout_update_order_meta', 'save_custom_checkout_hidden_field', 10, 1 );
function save_custom_checkout_hidden_field( $order_id ) {

    if ( ! empty( $_POST['user_link'] ) )
        update_post_meta( $order_id, '_user_link', sanitize_text_field( $_POST['user_link'] ) );

}

代码进入您的function.php文件活动的子主题（或主题）或任何插件文件中。

代码已经过测试并且可以正常工作
