Question

我正在寻找扩展wc-api / vX / orders / reponse的方法。我已将多个自定义字段添加到结帐中（例如：关系编号，交货日期等）。这些元保存在订单（wp_postmeta表）中。但他们为什么不带着api回来？

通常，您可以使用以下代码扩展api响应：

add_action( 'rest_api_init', 'custom_register_api_fields' );

function custom_register_api_fields() {
    register_rest_field( 'shop_order','relation_number',
    array(
        'get_callback'    => 'custom_api_meta_callback',
        'update_callback' => null,
        'schema'          => null,
    )
    );
}

/**
*
* @param array $object Details of current post.
* @param string $field_name Name of field.
* @param WP_REST_Request $request Current request
*
* @return mixed
*/

function custom_api_meta_callback( $object, $field_name, $request ) {
 return get_post_meta( $object[ 'id' ], $field_name, true );
}

但是当我测试响应时（使用Postman和php lib），my-website.co/wc-api/v2/orders自定义meta不可见。

有没有办法为wc-api注册api字段？

TNX！

Answer 1

我有相同的要求，将新值添加到“ line_items”中以进行响应

使用wc api v2

https://website.com/wp-json/wc/v2/orders

function get_product_order_image( $response, $object, $request ) {

    if( empty( $response->data ) )
        return $response;
    $order_pid= $response->data['line_items'][0]['product_id'];
     $l_w_product_meta = get_post_meta($response->data['line_items'][0]['product_id']);
    $order_imgUrl= wp_get_attachment_url( $l_w_product_meta['_thumbnail_id'][0], 'full' );

    $response->data['line_items'][0]['cover_image'] = $order_imgUrl;

    return $response;
} 

add_filter( "woocommerce_rest_prepare_shop_order_object", array( $this, "get_product_order_image"), 10, 3 );

结果 cover image added to line item result

我希望这会对功能方面的人有所帮助。

REST API 挂钩，用于向“line_items”添加新值（产品图片）以响应简单产品和可变产品

也可用于多种产品

function get_product_order_image( $response, $object, $request ) {

    if( empty( $response->data ) )
        return $response;
        
    $images = array();
    
    foreach($response->data['line_items'] as $key => $productItems){
        $productID = $productItems['product_id'];
        $variationID = $productItems['variation_id'];
        
        if($variationID == 0){
            $thumbnailID = get_post_meta( $productID, '_thumbnail_id', true);
            $attachment = wp_get_attachment_image_src($thumbnailID, 'woocommerce_thumbnail' );
            $image = $attachment[0];
        }else{
            $variation = new WC_Product_Variation( $variationID );
            $image_id = $variation->get_image_id();
            $attachment = wp_get_attachment_image_src($image_id, 'woocommerce_thumbnail' );
            $image = $attachment[0];
        }
        
        $response->data['line_items'][$key]['image'] = $image;
    
    }     

    return $response;
} 

add_filter( "woocommerce_rest_prepare_shop_order_object", "get_product_order_image", 10, 3 );

请求：

wp-json/wc/v3/orders

wp-json/wc/v3/orders/XXX

wp-json/wc/v3/orders/?customers=XXX
