将自定义数据从购物车项目传递到Woocommerce 3中的“订单"元数据 [英] Passing custom data from cart items to Order meta in Woocommerce 3

问题描述

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.

I have implemented a custom HTML Form and asking for some data which my customers will pass to place order successfully. Without these details my order has no importance.

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.

For HTML form, I am referencing some custom PHP script which is below and which processes POST data from the Form and creates Cart with these data programmatically. Thanks @LoicTheAztec to help me achieve this.

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.

As you see we have programmatically created a cart item using WC_Cart add_to_cart() method. So, all custom data is being saved to Cart as custom cart item data.

现在，我们还在functions.php中放置了一个代码块，以在Checkout页面上打印这些数据.

And now, we have also placed a code block into functions.php to print these data on Checkout page.

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.

Now, I am trying to add these data printed on Checkout page to the Order page as well. As my order can't be completed without these data, user need to fill up these data and when he creates order, these data needs to be passed to the Order Summary page as well. And admin also needs to be able to see these data so he can process the order.

我希望此描述能清除所有内容，并再次感谢@LoicTheAztec，使我能够做到这一点.非常感谢.

I hope this description clears everything and thanks again @LoicTheAztec to make me able to do this. Thank you very much.

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"订单商品" 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:

We will save this custom customer data as "Hidden" order "item" meta data and then as order meta data too as this is related to subscriptions with a unique order item:

// 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 );
    }
}

代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试，可以正常工作.

Code goes in function.php file of your active child theme (or active theme). Tested and works.

2)显示已保存的自定义数据:

下面的代码也使用我们的实用程序功能custom_data_keys_labels() ...

The code below also use our utility function 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;
}

代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试，可以正常工作.

Code goes in function.php file of your active child theme (or active theme). Tested and works.
