将收到的订单 woocommerce 发送给发送电子邮件通知的经销商

Question

我有一个电子邮件列表（经销商），当我在 wp-admin 中收到订单时，我需要打开此订单并将此订单发送给经销商（商业、用户......）。每个经销商都有一封电子邮件，并在他已发送给该经销商的自定义字段中标记此订单。

在我的 woocommerce 订单页面中，我需要打开订单并执行以下操作：

• 订单 001 --- > 发送至 Email1@exemple.com = 订单 001 - 发送至 Email1@exemple.com
• 订单 002 ----> 发送至 Email2@exemple.com = 订单 002 - 发送至 Email2@exemple.com
• 订单 003 --- > 发送至 Email1@exemple.com = 订单 003 - 发送至 Email1@exemple.com

我不知道从哪里开始。

有没有人有想法或一些代码来实现这样的事情？

谢谢

Answer 1

这是一个满足您需求的完整答案。您必须在第二个函数中设置经销商列表中的电子邮件和姓名数组。

此代码将在后端订单编辑页面中显示一个带有选择器的自定义元框，如果您要设置经销商并点击“保存订单”...

新订单通知电子邮件只会发送到该经销商电子邮件地址一次。

代码如下：

//Adding Meta container admin shop_order pages
add_action( 'add_meta_boxes', 'my_custom_order_meta_box' );
if ( ! function_exists( 'my_custom_order_meta_box' ) )
{
    function my_custom_order_meta_box()
    {
        global $woocommerce, $order, $post;

        add_meta_box( 'dealer_dispatch', __('Dealer Dispatch','woocommerce'), 'add_order_custom_fields_for_packaging', 'shop_order', 'side', 'core' );
    }
}


//adding Meta field in the meta container admin shop_order pages
if ( ! function_exists( 'add_order_custom_fields_for_packaging' ) )
{
    function add_order_custom_fields_for_packaging()
    {
        global $woocommerce, $order, $post;

        // Define HERE your array of values  <==  <==  <==  <==  <==  <==  <==  <==
        $option_values = array(
            'default'               => __('no selection', 'woocommerce'),
            'dealer1@email.com'     => 'Dealer 1 Name',
            'dealer2@email.com'     => 'Dealer 2 Name',
            'dealer3@email.com'     => 'Dealer 3 Name',
        );

        // Get the values from the custom-fields (if they exist)
        $meta_field_data = get_post_meta( $post->ID, '_dealer_dispatch', true );
        $dealer_email_sent = get_post_meta( $post->ID, '_dealer_email_sent', true );

        echo '<input type="hidden" name="my-custom-order_meta-box-nonce" value="'. wp_create_nonce() .'">

            <label for="dealer_dispatch">'.__('Select a dealer', 'woocommerce').'</label><br>
            <select name="dealer_dispatch">';

                    foreach( $option_values as $option_key => $option_value ){

                        if ( $meta_field_data == $option_key || 'default' == $option_key )
                            $selected = ' selected';
                        else
                            $selected = '';

                        echo '<option value="'.$option_key.'"'.$selected.'>'. $option_value.'</option>';
                    }

            echo '</select><br>';

        // if an email has been sent to the dealer we display a message
        if( ! empty($dealer_email_sent) )
            echo '<p style="color:green; font-weight:bold;">'.__('Email sent to: ', 'woocommerce').$dealer_email_sent.'</p>';
    }
}


//Save the data of the Meta field
add_action( 'save_post', 'add_my_custom_field_for_order_meta_box', 20, 1 );
if ( ! function_exists( 'add_my_custom_field_for_order_meta_box' ) )

        // Check if our nonce is set.
        if ( ! isset( $_POST[ 'my-custom-order_meta-box-nonce' ] ) ) {
            return $post_id;
        }
        $nonce = $_REQUEST[ 'my-custom-order_meta-box-nonce' ];

        //Verify that the nonce is valid.
        if ( ! wp_verify_nonce( $nonce ) ) {
            return $post_id;
        }

        // Continuing only if form is submited.
        if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
            return $post_id;
        }

        // Check and set the user's permissions.
        if ( 'page' == $_POST[ 'post_type' ] ) {

            if ( ! current_user_can( 'edit_page', $post_id ) ) {
                return $post_id;

            }
        }

        //  --  --  IT IS SECURED NOW  --  --

        // Sanitize input and update order meta data custom field.
        $dealer_dispatch = $_POST[ 'dealer_dispatch' ];

            // Creating a custom meta data for this order to avoid sending this email 2 times
            update_post_meta( $post_id, '_dealer_email_sent', $dealer_dispatch_val );

    }
}

此代码已经过测试并且可以工作。
