在Woocommerce 3中将自定义数据从购物车项目传递到Order meta

我已经实现了一个自定义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,我的订单就不重要了。

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

script.php文件代码:

<?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,我们已经使用WC_Cart add_to_cart()方法以编程方式创建了购物车商品。因此,所有自定义数据都将作为自定义购物车商品数据保存到购物车。

现在,我们还将代码块放入functions.php中,以在Checkout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,我正尝试将这些在Checkout页面上打印的数据也添加到Order页面中。由于没有这些数据无法完成我的订单,因此用户需要填写这些数据,并且在创建订单时,这些数据也需要传递到“订单摘要”页面。管理员还需要能够查看这些数据,以便他能够处理订单。

我希望此说明能清除所有内容,并再次感谢@LoicTheAztec,使我能够做到这一点。非常感谢。

更新2 -两步

1)保存数据:

我们将此自定义客户数据另存为“隐藏”订单“项目” 元数据,然后另存为订单元数据,因为这与具有唯一身份的订阅有关订单项:

// 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:

下面的代码也使用我们的实用程序功能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;
}
