如何将WooCommerce结帐自定义字段保存到用户元 [英] How to save WooCommerce checkout custom fields to user meta

问题描述

我已经使用 PODS.io Wordpress插件为用户元创建了以下自定义字段：

I've created the following custom fields for the user meta using the PODS.io Wordpress plugin:

• 出生日期


• 紧急联络人姓名


• 关系


• emergency_phone

• date_of_birth
• emergency_contact_name
• relation
• emergency_phone

我已使用以下代码将这些字段添加到WooCommerce结帐中，在额外的信息下，在我主题的 functions.php 中：

I've added these fields to the WooCommerce checkout, under extra information, by using the following code in my theme's functions.php:

add_action( 'woocommerce_after_order_notes', 'my_custom_checkout_field' );

function my_custom_checkout_field( $checkout ) {

    woocommerce_form_field( 'date_of_birth', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Date of Birth'),
        'placeholder'   => __('dd/mm/yyyy'),
        ), $checkout->get_value( 'date_of_birth' ));

    woocommerce_form_field( 'emergency_contact_name', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Emergency Contact Name'),
        'placeholder'   => __('contact name'),
        ), $checkout->get_value( 'emergency_contact_name' ));

    woocommerce_form_field( 'relation', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Emergency Relation'),
        'placeholder'   => __('wife/husband'),
        ), $checkout->get_value( 'relation' ));

    woocommerce_form_field( 'emergency_phone', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Emergency Phone'),
        'placeholder'   => __('xxxx xxx xxx / xxxx xxxx'),
        ), $checkout->get_value( 'emergency_phone' ));

}

错误检查：

add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');

function my_custom_checkout_field_process() {
    // Check if set, if its not set add an error.
    if ( ! $_POST['date_of_birth'] )
        wc_add_notice( __( 'Please enter your date of birth' ), 'error' );
    if ( ! $_POST['emergency_contact_name'] )
        wc_add_notice( __( 'Please enter your Emergency Contact Name' ), 'error' );     
    if ( ! $_POST['relation'] )
        wc_add_notice( __( 'Please enter how your Emergency Contact is related to you' ), 'error' );
    if ( ! $_POST['emergency_phone'] )
        wc_add_notice( __( 'Please enter the phone number of your Emergency Contact' ), 'error' );              
}

（希望）在结帐时更新用户元 ：

(Hopefully) update the user meta upon checkout:

add_action( 'woocommerce_checkout_update_user_meta', 'my_custom_checkout_field_update_user_meta' );

function my_custom_checkout_field_update_order_meta( $order_id ) {
    if ( !empty( $_POST['date_of_birth'] ) ) {
        $dob = sanitize_text_field( $_POST['date_of_birth'] );
        update_user_meta( $current_user->ID, 'date_of_birth', $dob);
    }
    if ( ! empty( $_POST['emergency_contact_name'] ) ) {
        update_user_meta( $user_id, 'emergency_contact_name', sanitize_text_field( $_POST['emergency_contact_name'] ) );
    }
    if ( ! empty( $_POST['relation'] ) ) {
        update_user_meta( $user_id, 'relation', sanitize_text_field( $_POST['relation'] ) );
    }
    if ( ! empty( $_POST['emergency_phone'] ) ) {
        update_user_meta( $user_id, 'emergency_phone', sanitize_text_field( $_POST['emergency_phone'] ) );
    }           
}

不幸的是，用户元自定义字段在以下情况下不会更新我结帐。

Unfortunately, the user meta custom fields are not updated when I checkout.

我可以使用以下代码更新订单元自定义字段：

I can update the order meta custom fields with the following code:

add_action( 'woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta' );

function my_custom_checkout_field_update_order_meta( $order_id ) {
    if ( ! empty( $_POST['date_of_birth'] ) ) {
        update_post_meta( $order_id, 'Date Of Birth', sanitize_text_field( $_POST['date_of_birth'] ) );
    }
    if ( ! empty( $_POST['emergency_contact_name'] ) ) {
        update_post_meta( $order_id, 'Emergency Contact Name', sanitize_text_field( $_POST['emergency_contact_name'] ) );
    }
    if ( ! empty( $_POST['relation'] ) ) {
        update_post_meta( $order_id, 'Emergency Relation', sanitize_text_field( $_POST['relation'] ) );
    }
    if ( ! empty( $_POST['emergency_phone'] ) ) {
        update_post_meta( $order_id, 'Emergency Phone', sanitize_text_field( $_POST['emergency_phone'] ) );
    }           
}

但是，我们需要用户meta中的自定义字段

However, we need the custom fields in the user meta, not the order meta.

您能看到结账到用户元数据时保存自定义字段的代码有什么问题吗？

谢谢。

推荐答案

首先，您应该添加这样的自定义字段：（使用 woocommerce_checkout_fields 过滤器）

first, you should add your custom fields like this: (use woocommerce_checkout_fields filter)

function reigel_woocommerce_checkout_fields( $checkout_fields = array() ) {

    $checkout_fields['order']['date_of_birth'] = array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Date of Birth'),
        'placeholder'   => __('dd/mm/yyyy'),
        'required'      => true, 
        );

    return $checkout_fields;
}
add_filter( 'woocommerce_checkout_fields', 'reigel_woocommerce_checkout_fields' );

添加'required'并将其设置为 true 与检查此字段是否设置的效果相同。 （您的错误检查）

adding 'required' and setting it to true will have the same effect with how you check if this field is set or not. (your "Error checking")

然后在 woocommerce_checkout_update_user_meta 中，第一个参数不是 $ order_id ，但 $ customer_id 。您也应该知道第二个参数是 $ posted 。 $ posted 包含 $ _ POST [] 数据。

then in your woocommerce_checkout_update_user_meta, the first parameter is not $order_id but the $customer_id. You should know too that the second parameter is $posted. $posted contains the $_POST[] data. Including your custom fields if you did the code above.

function reigel_woocommerce_checkout_update_user_meta( $customer_id, $posted ) {
    if (isset($posted['date_of_birth'])) {
        $dob = sanitize_text_field( $posted['date_of_birth'] );
        update_user_meta( $customer_id, 'date_of_birth', $dob);
    }
}
add_action( 'woocommerce_checkout_update_user_meta', 'reigel_woocommerce_checkout_update_user_meta', 10, 2 );
