将自定义数据从购物车项目传递到 Woocommerce 3 中的订单元

Passing custom data from cart items to Order meta in Woocommerce 3

我已经实现了自定义 HTML 表单并要求我的客户传递一些数据以成功下订单。没有这些细节,我的订单就没有意义。

对于 HTML 表单,我引用了下面的一些自定义 PHP 脚本,它处理来自表单的 POST 数据并以编程方式使用这些数据创建购物车。感谢@LoicTheAztec 帮助我实现这一目标。

script.php文件编码:

<?php

    require_once("../wp-load.php");

    $customer_name = $_POST["customer_name"];
    $customer_email = $_POST["customer_email"];
    $customer_sex = $_POST["customer_sex"];
    $customer_age = $_POST["customer_age"];
    $product_id = $_POST["product_id"];

$custom_data = array(); // Initializing

    if( isset($_POST['customer_name']) && ! empty($_POST['customer_name']) )
        $custom_data['custom_data']['name']  =  $_POST['customer_name'];
    if( isset($_POST['customer_email']) && ! empty($_POST['customer_email']) )
        $custom_data['custom_data']['email'] = $_POST['customer_email'];
    if( isset($_POST['customer_sex']) && ! empty($_POST['customer_sex']) )
        $custom_data['custom_data']['sex']   = $_POST['customer_sex'];
    if( isset($_POST['customer_age']) && ! empty($_POST['customer_age']) )
        $custom_data['custom_data']['age']   = $_POST['customer_age'];

    global $woocommerce;

    if (WC()->cart->add_to_cart( $product_id, '1', '0', array(), $custom_data )) {
        var_dump($product_id);
    } else {
        var_dump($customer_name);
    }

    header("Location: ./checkout");
?>

如您所见,我们使用 WC_Cart add_to_cart() 方法以编程方式创建了一个购物车项目。因此,所有自定义数据都作为 自定义购物车项目数据.

保存到购物车

现在,我们还在 functions.php 中放置了一个代码块,用于在结帐页面上打印这些数据。

add_action( 'woocommerce_after_order_notes', 'my_custom_checkout_field' );

function my_custom_checkout_field( $checkout ) {

    //var_dump($checkout);
    global $woocommerce;

    echo '<div id="my_custom_checkout_field"><h2>' . __('Child Info') . '</h2>';

    foreach ( $woocommerce->cart->get_cart() as $cart_item ) {
        if( isset($cart_item['custom_data']) ) {

            $custom_data = $cart_item['custom_data'];

            echo("<div>Name: <strong>" . $custom_data['name'] . "</strong></div>");
            echo("<div>Email: <strong>" . $custom_data['email'] . "</strong></div>");
            echo("<div>Gender: <strong>" . $custom_data['sex'] . "</strong></div>");
            echo("<div>Age: <strong>" . $custom_data['age'] . "</strong></div>");

        }

    }

    echo '</div>';

}

现在,我正在尝试将结帐页面上打印的这些数据也添加到订单页面。由于没有这些数据我的订单无法完成,用户需要填写这些数据,当他创建订单时,这些数据也需要传递到订单摘要页面。并且管理员还需要能够看到这些数据,以便他可以处理订单。

我希望这个描述能解决所有问题,再次感谢@LoicTheAztec 让我能够做到这一点。非常感谢。

更新 2 - 两个步骤

1) 保存数据:

我们将此自定义客户数据保存为"Hidden"订单"item"元数据,然后作为订单元数据,因为这与具有唯一订单项的订阅相关:

// Utility function: array of custom customer key/label pairs
function custom_data_keys_labels(){
    return array(
        'name'  => __('Customer name'),     'email' => __('Customer email'),
        'sex'   => __('Customer gender'),   'age'   => __('Customer age'),
    );
}

// Add/save custom field value as custom HIDDEN order item meta data
add_action( 'woocommerce_checkout_create_order_line_item', 'custom_field_update_order_item_meta', 20, 4 );
function custom_field_update_order_item_meta( $item, $cart_item_key, $values, $order ) {
    if ( ! isset( $values['custom_data'] ) )
        return;

    $custom_data = $values['custom_data'];
    $meta_data   = array();
    $labels_keys = custom_data_keys_labels();

    foreach( $labels_keys as $key => $label ){
        if ( isset( $custom_data[$key] ) )
            $meta_data[$key] = $custom_data[$key];
    }

    if ( sizeof( $meta_data ) > 0 )
        $item->update_meta_data( __('_customer_data'), $meta_data );

    return $cart_item_data;
}

// Add/save custom fields values as custom order meta data
add_action( 'woocommerce_checkout_create_order', 'my_custom_checkout_field_update_order_meta', 20, 2 );
function my_custom_checkout_field_update_order_meta( $order, $data ) {

    $order_items = $order->get_items(); // Order itesm
    $item        = reset($order_items); // Keep only the first order item

    $item_data   = $item->get_meta( '_customer_data' ); // Get custom customer data

    if( is_array($item_data) && sizeof($item_data) > 0 ){
        foreach( $item_data as $key => $value ) {
            if ( isset( $item_data[$key] ) )
                $order->update_meta_data( '_customer_' . $key, $value );
        }
        // Mark as data saved
        $order->update_meta_data( '_customer_data_set', true );
    }
}

2) 显示保存的自定义数据:

下面的代码也使用了我们的效用函数custom_data_keys_labels()

// Order pages (frontend and admin) display
add_filter( 'woocommerce_order_details_after_order_table' , 'display_admin_order_meta_cutom_data', 20, 1 ); // Front
add_action( 'woocommerce_admin_order_data_after_billing_address', 'display_admin_order_meta_cutom_data', 20, 1 ); // Admin
function display_admin_order_meta_cutom_data( $order ){
    $labels_keys = custom_data_keys_labels();
    if( $order->get_meta( '_customer_data_set' ) ){
        if( is_admin() ){ // Admin
            echo '<p>';
            foreach( $labels_keys as $key => $label ){
                if ( $order->get_meta( '_customer_' . $key ) )
                    echo '<strong>' . $label . ':</strong> ' . $order->get_meta( '_customer_' . $key ) . '<br>';
            }
            echo '</p>';
        }
        else { // Front end: order view and Order received (thankyou)
            echo '<table class="woocommerce-table"><tbody>';
            foreach( $labels_keys as $key => $label ){
                if ( $order->get_meta( '_customer_' . $key ) )
                    echo '<tr><th>' . $label . ':</th><td>' . $order->get_meta( '_customer_' . $key ) . '</td></tr>';
            }
            echo '</tbody></table>';
        }
    }
}

// Email notifications display
add_filter( 'woocommerce_email_order_meta_fields' , 'display_email_cutom_data', 20, 3 );
function display_email_cutom_data ( $fields, $sent_to_admin, $order ) {
    $labels_keys = custom_data_keys_labels();
    if( $order->get_meta( '_customer_data_set' ) ){
        foreach( $labels_keys as $key => $label ){
            $fields['customer_' . $key] = array(
                'label' => $label,
                'value' => $order->get_meta( '_customer_' . $key ),
            );
        }
    }
    return $fields;
}
