php - 发送收到的订单 woocommerce 给经销商发送电子邮件通知

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，我需要打开一个订单并执行如下操作:

• Order 001 --- > send to Email1@exemple.com = Order 001 - Sent to Email1@exemple.com
• Order 002 ----> send to Email2@exemple.com = Order 002 - Sent to Email2@exemple.com
• Order 003 --- > send to Email1@exemple.com = Order 003 - Sent to 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名称数组。

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数据框，如果您要设置经销商并单击“保存订单”……

新订单通知电子邮件将仅发送一次到该经销商电子邮件地址。

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' ) )

    function add_my_custom_field_for_order_meta_box( $post_id ) {

        ## Verify and securing data. ##

        // 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;
            }
        } else {

                return $post_id;
            }
        }

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

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

        // Saving the selected value
        if( 'default' != $dealer_dispatch )
            update_post_meta( $post_id, '_dealer_dispatch', sanitize_text_field( $dealer_dispatch ) );


        # SEND CUSTOM EMAIL ONLY ONCE #

        $dealer_dispatch_val = get_post_meta( $post_id, '_dealer_dispatch', true );
        $dealer_email_sent = get_post_meta( $post_id, '_dealer_email_sent', true );

        if( empty($dealer_email_sent) && !empty($dealer_dispatch_val) ){

            $email_notifications = WC()->mailer()->get_emails();
            $email_notifications['WC_Email_New_Order']->recipient = $dealer_dispatch;
            $email_notifications['WC_Email_New_Order']->trigger( $post_id );

            // 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 );
        }
    }
}

代码位于您的事件子主题(或主题)的 function.php 文件中或任何插件文件中。

此代码已经过测试并且可以工作。
