我创建了一个Woocommerce插件，并要求它做两件事：
根据购物车中的产品差异，向特定的电子邮件地址发送通知消息。
电子邮件必须仅包含相关产品，而不包含包含其他属性的产品。
例如：
产品A有一个名为Chef的属性，其中chef-one和chef-two为变量Terms。用户可以从chef-one或chef-two中选择产品A.
如果用户从chef-one中选择产品A，则必须将包含所订产品名称的chefone@email.com发送通知电子邮件（因为它会显示在常规的Woocommerce通知电子邮件中）。
如果用户从chef-one选择产品A，从chef-two选择产品B，则必须向仅包含产品A的chef-one发送通知电子邮件，并且必须向仅包含Product的chef-two发送通知电子邮件乙
我使用https://www.skyverge.com/blog/how-to-add-a-custom-woocommerce-email/上的教程创建了该插件，并根据上述目的对其进行了调整。
我还修改了代码，发现了以下解决方案： Adding a custom woocommerce email based on the product attribute Woocommerce - Need to send email to specific address based on zip code
以下是我的插件的类文件中的代码：
if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly
/**
* A custom WAKIKI Order WooCommerce Email class
*
* @since 0.1
* @extends \WC_Email
*/
class WC_Wakiki_Order_Email extends WC_Email {
/**
* Set email defaults
*
* @since 0.1
*/
public function __construct() {
// set ID, this simply needs to be a unique name
$this->id = 'wc_wakiki_order';
// this is the title in WooCommerce Email settings
$this->title = 'WAKIKI Order';
// this is the description in WooCommerce email settings
$this->description = 'WAKIKI Order Notification emails are sent when a customer places an order on the website';
// these are the default heading and subject lines that can be overridden using the settings
$this->heading = 'WAKIKI Delivery Order';
$this->subject = 'WAKIKI Delivery Order';
// these define the locations of the templates that this email should use, we'll just use the new order template since this email is similar
$this->template_html = 'emails/admin-new-order.php';
$this->template_plain = 'emails/plain/admin-new-order.php';
// Trigger on new paid orders
add_action( 'woocommerce_order_status_pending_to_processing_notification', array( $this, 'trigger' ) );
add_action( 'woocommerce_order_status_failed_to_processing_notification', array( $this, 'trigger' ) );
// Call parent constructor to load any other defaults not explicity defined here
parent::__construct();
// this sets the recipient to the settings defined below in init_form_fields()
$this->recipient = $this->get_option( 'recipient' );
// if none was entered, just use the WP admin email as a fallback
if ( ! $this->recipient )
$this->recipient = get_option( 'admin_email' );
}
/**

* @param int $order_id
*/
public function trigger( $order_id ) {
// Bail if no order ID is present
if ( ! $order_id )
return;
$order = new WC_Order( $order_id );
// Find the product_id
$items = $order->get_items();
foreach ( $items as $item ) {
$product_id = $item['product_id'];
}
// From the product_id get the product attribute
$product = new WC_Product( $product_id ); // create an object of WC_Product class
$patt = $product->get_attributes(); // call get_attributes method
// Condition valid to send the email (if the attributes is chef)
if ( array_key_exists('pa_chef', $patt) )
// Determine which email address to send to, based on Product Attribute Term)
add_filter( 'new_order' , 'add_recipient', 20, 2 );
function add_recipient( $email, $order ) {
$additional_email = "info@email.com";
$terms = get_terms("pa_chef");
if( $order->$term->name == "pa_chef-one" ){
$email = explode( ',', $email );
array_push( $email, $additional_email );
}
return $email;
}
{
// Send the email
// Setup order object
$this->object = new WC_Order( $order_id );
$this->recipient = $this->object->billing_email;
// Replace variables in the subject/headings
$this->find[] = '{order_date}';
$this->replace[] = date_i18n( woocommerce_date_format(), strtotime( $this->object->order_date ) );
$this->find[] = '{order_number}';
$this->replace[] = $this->object->get_order_number();
if ( ! $this->is_enabled() || ! $this->get_recipient() )
return;
// Send the email!
$this->send( $this->get_recipient(), $this->get_subject(), $this->get_content(), $this->get_headers(), $this->get_attachments() );
}
else
{
return; //do nothing if there is not chef attribute
}
}
/**

public function get_content_plain() {
ob_start();
woocommerce_get_template( $this->template_plain, array(
'order' => $this->object,
'email_heading' => $this->get_heading()
) );
return ob_get_clean();
}
/**

public function init_form_fields() {
$this->form_fields = array(
'enabled' => array(
'title' => 'Enable/Disable',
'type' => 'checkbox',
'label' => 'Enable this email notification',
'default' => 'yes'
),
'recipient' => array(
'title' => 'Recipient(s)',
'type' => 'text',
'description' => sprintf( 'Enter recipients (comma separated) for this email. Defaults to <code>%s</code>.', esc_attr( get_option( 'admin_email' ) ) ),
'placeholder' => '',
'default' => ''
),
'subject' => array(
'title' => 'Subject',
'type' => 'text',
'description' => sprintf( 'This controls the email subject line. Leave blank to use the default subject: <code>%s</code>.', $this->subject ),
'placeholder' => '',
'default' => ''
),
'heading' => array(
'title' => 'Email Heading',
'type' => 'text',
'description' => sprintf( __( 'This controls the main heading contained within the email notification. Leave blank to use the default heading: <code>%s</code>.' ), $this->heading ),
'placeholder' => '',
'default' => ''
),
'email_type' => array(
'title' => 'Email type',
'type' => 'select',
'description' => 'Choose which format of email to send.',
'default' => 'html',
'class' => 'email_type',
'options' => array(
'plain' => __( 'Plain text', 'woocommerce' ),
'html' => __( 'HTML', 'woocommerce' ),
'multipart' => __( 'Multipart', 'woocommerce' ),
)
)
);
}
这与我能够得到的一样接近，但它无法正常工作。我怀疑问题出在“确定要发送到哪个电子邮件地址，基于产品属性术语”这一行的某处。该插件正在加载，直到我添加该部分。
该函数是否应该在一个单独的插件文件中？
我还需要帮助，让电子邮件只包含与发送给它的供应商相关的信息。
非常感谢任何帮助您使用此插件的工作。

过滤器
DiskFileItemFactory factory = new DiskFileItemFactory(1024*1024, Files.createTempDirectory("mytemp").toFile());并不存在于WooCommerce （或代码中）
正确的过滤器挂钩（位于WC_Email类核心代码，第269行）就是这个：
new_order在此挂钩中， $recipient = apply_filters( 'woocommerce_email_recipient_' . $this->id, $this->recipient, $this->object );
是＆＃39; $this->id＆＃39;为了你。
您的代码中存在重大错误：
new_order或"one"，但绝对不是 "chef-one"，因为 "pa_chef-one" 是您的属性的分类标本＆＃34; Chef＆＃34;。所以正确的代码应该是这样的：
"pa_chef"代码放在活动子主题（或主题）的function.php文件中，或者放在任何插件文件中。
