用于自定义支付网关的WooCommerce自定义电子邮件-Java 学习之路

所以我为WooCommerce创建了一个add on插件 . 我有一个自定义类来扩展“检查”支付网关，允许用户在没有付款的情况下执行批发结账 . 到目前为止，此功能完美无缺 . 问题是我无法使用自定义电子邮件来使用此自定义付款 . 我不确定我是否将两个自定义类连接在一起 . 我是否在触发器中丢失了某些东西或者使用了错误的钩子来触发？

就在这里，我包括电子邮件类..

function add_dealer_invoice_woocommerce_email( $email_classes ) {
// include our custom email class
require_once( 'includes/class-wc-dealer-invoice-email.php' );

// add the email class to the list of email classes that WooCommerce loads
$email_classes['WC_Dealer_Invoice_Email'] = new WC_Dealer_Invoice_Email();

return $email_classes;
}

add_filter( 'woocommerce_email_classes', 'add_dealer_invoice_woocommerce_email' );
// Register new status for woocomerce 2.2+
function register_dealer_invoice_order_status() {
register_post_status( 'wc-dealer-invoice', array(
    'label'                     => 'Dealer Invoice',
    'public'                    => true,
    'exclude_from_search'       => false,
    'show_in_admin_all_list'    => true,
    'show_in_admin_status_list' => true,
    'label_count'               => _n_noop( 'Awaiting payment <span class="count">(%s)</span>', 'Awaiting payment <span class="count">(%s)</span>' )
) );
}
 add_action( 'init', 'register_dealer_invoice_order_status' );

这是扩展WC_Email的自定义电子邮件类

if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly

class WC_Dealer_Invoice_Email extends WC_Email {

public function __construct() {

    // set ID, this simply needs to be a unique name
    $this->id = 'wc_dealer_invoice';

    // this is the title in WooCommerce Email settings
    $this->title = 'Dealer Invoice';

    // this is the description in WooCommerce email settings
    $this->description = 'Dealer Invoice Notification emails are sent when a customer places a wholesale order on consignment';

    // these are the default heading and subject lines that can be overridden using the settings
    $this->heading = 'Dealer Invoice Order';
    $this->subject = 'Dealer Invoice 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' ) );
    add_action( 'woocommerce_checkout_order_processed',  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' );
}

    // bail if shipping method is not expedited
