如何将WooCommerce结帐自定义字段保存到用户元

Question

我使用PODS.io Wordpress插件为用户元创建了以下自定义字段:

• 出生日期
• 紧急联络名字
• 关系
• emergency_phone

我通过在我的主题中使用以下代码,在额外信息下将这些字段添加到WooCommerce结帐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)在结账时更新用户元数据:

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,我结帐时不会更新用户元自定义字段.

我可以使用以下代码更新订单元自定义字段:

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,我们需要用户元数据中的自定义字段,而不是订单元数据.

你能看到在结账时保存自定义字段到用户元的代码有什么问题吗？

谢谢.

Answer 1

首先,你应该像这样添加自定义字段:(使用woocommerce_checkout_fields过滤器)

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'和设置它将true与检查是否设置此字段具有相同的效果.(你的"错误检查")

然后在你的woocommerce_checkout_update_user_meta,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.如果您执行上面的代码,请包括您的自定义字段.

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 );
