Question

我已经创建了一个自定义订单状态和一个自定义电子邮件，但是当订单设置为自定义状态时，似乎无法触发电子邮件。谁能指出我正确的方向？

这是用于创建自定义订单状态并添加电子邮件的代码：

<?php 
/**
*Plugin Name: WooCommerce Custom Order Status
*Description: Creates a custom order status in woocommerce and creates a custom email notification.
*/ 

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

// BEGIN ENQUEUE PARENT ACTION
// AUTO GENERATED - Do not modify or remove comment markers above or below:

// END ENQUEUE PARENT ACTION

// Register New Order Statuses
function wpex_wc_register_post_statuses() {
    register_post_status( 'wc-customer-approval', array(
        'label'                     => _x( 'Awaiting Customer Approval', 'WooCommerce Order status', 'text_domain' ),
        'public'                    => true,
        'exclude_from_search'       => false,
        'show_in_admin_all_list'    => true,
        'show_in_admin_status_list' => true,
        'label_count'               => _n_noop( 'Approved (%s)', 'Approved (%s)', 'text_domain' )
    ) );
}
add_filter( 'init', 'wpex_wc_register_post_statuses' );

// Add New Order Statuses to WooCommerce
function wpex_wc_add_order_statuses( $order_statuses ) {
    $order_statuses['wc-customer-approval'] = _x( 'Awaiting Customer Approval', 'WooCommerce Order status', 'text_domain' );
    return $order_statuses;
}
add_filter( 'wc_order_statuses', 'wpex_wc_add_order_statuses' );

/**
 *  Add a custom email to the list of emails WooCommerce should load
 *
 * @since 0.1
 * @param array $email_classes available email classes
 * @return array filtered available email classes
 */
function add_signature_woocommerce_email( $email_classes ) {

    // include our custom email class
    require( 'includes/class-wc-signature-email.php' );

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

    return $email_classes;

}
add_filter( 'woocommerce_email_classes', 'add_signature_woocommerce_email' );

这是电子邮件类文件中的代码：

<?php

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

/**

 * @extends \WC_Email

    public function __construct() {

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

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

        // this is the description in WooCommerce email settings
        $this->description = 'Signature Email Notification';

        // these are the default heading and subject lines that can be overridden using the settings
        $this->heading = 'Customer Approval Needed';
        $this->subject = 'Customer Approval Needed';

        // 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_customer-approval_notification', array( $this, 'trigger' ) );
        add_action( 'woocommerce_order_status_on-hold_to_customer-approval_notification', array( $this, 'trigger' ) );
        add_action( 'woocommerce_order_status_failed_to_customer-approval_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' );
    }
    /**
     * Determine if the email should actually be sent and setup email merge variables
     *
     * @since 0.1

     */
    public function trigger( $order_id ) {

        // bail if no order ID is present
        if ( ! $order_id )
            return;

        // setup order object
        $this->object = new WC_Order( $order_id );

        // 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;

        // woohoo, send the email!
        $this->send( $this->get_recipient(), $this->get_subject(), $this->get_content(), $this->get_headers(), $this->get_attachments() );
    }

                    'html'      => 'HTML', 'woocommerce',
                    'multipart' => 'Multipart', 'woocommerce',
                )
            )
        );
    }
} // end \WC_Signature_Email class

到目前为止，我已经设法找到了一些错误，因此我已将代码更新为最新版本。

谢谢，格里高

Answer 1

如果在类中使用钩子，则必须使用array( $this, $function )来传递函数名称，因此：

add_action( 'woocommerce_order_status_changed', array( $this, 'my_awesome_publication_notification' ) );

请参见Codex

自定义电子邮件不会在自定义状态更改时触发
