Woocommerce 自定义订单状态以及自定义电子邮件通知

Question

我正在使用一些已成功添加到 WooCommerce 的自定义订单状态。我已经能够自定义在订购某些类型的产品时发送给客户的电子邮件。有效，

现在我想要的是更改我的代码，因此它只发送自定义的电子邮件通知，而不是默认的 WooCommerce 处理邮件。

这是我的代码的工作示例：

// register a custom post status 'awaiting-delivery' for Orders
add_action( 'init', 'register_custom_post_status', 20 );
function register_custom_post_status() {
    register_post_status( 'wc-costum', array(
        'label'                     => _x( 'Instagram cursus', 'Order status', 'woocommerce' ),
        'public'                    => true,
        'exclude_from_search'       => false,
        'show_in_admin_all_list'    => true,
        'show_in_admin_status_list' => true,
        'label_count'               => _n_noop( 'Instagram cursus <span class="count">(%s)</span>', 'Instagram cursus <span class="count">(%s)</span>', 'woocommerce' )
    ) );
}

// Adding custom status 'awaiting-delivery' to order edit pages dropdown
add_filter( 'wc_order_statuses', 'custom_wc_order_statuses' );
function custom_wc_order_statuses( $order_statuses ) {
    $order_statuses['wc-costum'] = _x( 'Instagram cursus', 'Order status', 'woocommerce' );
    return $order_statuses;
}


// Adding custom status 'awaiting-delivery' to admin order list bulk dropdown
add_filter( 'bulk_actions-edit-shop_order', 'custom_dropdown_bulk_actions_shop_order', 20, 1 );
function custom_dropdown_bulk_actions_shop_order( $actions ) {
    $actions['mark_costum'] = __( 'Instagram cursus', 'woocommerce' );
    return $actions;
}

// Adding action for 'awaiting-delivery'
add_filter( 'woocommerce_email_actions', 'custom_email_actions', 20, 1 );
function custom_email_actions( $actions ) {
    $actions[] = 'woocommerce_order_status_wc-costum';
    return $actions;
}

// Removing default email action for 'processing' status
remove_action( 'woocommerce_order_status_processing', array( WC(), 'send_transactional_email' ), 10, 1 );


// Adding action for 'awaiting-delivery'
add_action( 'woocommerce_order_status_changed', 'custom_email_notification', 10, 4 );
function custom_email_notification( $order_id, $old_status, $new_status, $order ) {
    $custom_statuses = array( 'costum', 'costum2', 'costum3' );

    if ( in_array( $new_status, $custom_statuses ) ) {
        // Your settings here
        $email_key = 'WC_Email_Customer_Processing_Order'; // The email notification type

        // Get specific WC_emails object
        $email_obj = WC()->mailer()->get_emails()[ $email_key ];

        // Triggering the customized email
        $email_obj->trigger( $order_id );
    }
}

// Customize email heading for this custom status email notification
add_filter( 'woocommerce_email_heading_customer_processing_order', 'email_heading_customer_awaiting_delivery_order', 10, 2 );
function email_heading_customer_awaiting_delivery_order( $heading, $order ){
    if ($order->has_status('costum')) {
        $email_key   = 'WC_Email_Customer_Processing_Order'; // The email notification type
        $email_obj   = WC()->mailer()->get_emails()[$email_key]; // Get specific WC_emails object
        $heading_txt = __('Bevestigingsmail:','woocommerce'); // New heading text
        return $email_obj->format_string( $heading_txt );
    } 
    return $heading;
}

// Customize email subject for this custom status email notification
add_filter( 'woocommerce_email_subject_customer_processing_order', 'email_subject_customer_awaiting_delivery_order', 10, 2 );
function email_subject_customer_awaiting_delivery_order( $subject, $order ){
    if ($order->has_status('costum')) {
        $email_key   = 'WC_Email_Customer_Processing_Order'; // The email notification type
        $email_obj   = WC()->mailer()->get_emails()[$email_key]; // Get specific WC_emails object
        $subject_txt = sprintf( __('[%s] Instagram cursus (%s) - %s', 'woocommerce'), '{site_title}', '{order_number}', '{order_date}' ); // New subject text
        return $email_obj->format_string( $subject_txt );
    } 
    return $subject;
}

// Remove content before woocommerce_email_before_order_table hook
add_action('woocommerce_email_order_details', 'remove_content_before_order_table', 1, 4);

function remove_content_before_order_table($order, $sent_to_admin, $plain_text, $email) {
    // Remove unwanted content here
    remove_action('woocommerce_email_before_order_table', array($email, 'order_details'), 10);
}

// Customize email content for this custom status email notification
add_action( 'woocommerce_email_before_order_table', 'custom_content_for_customer_processing_order_email', 10, 4 );
function custom_content_for_customer_processing_order_email( $order, $sent_to_admin, $plain_text, $email ) {
    // Check if it's the "Customer Processing Order" email triggered by 'awaiting-delivery' status
    if ( $email->id === 'customer_processing_order' && $order->has_status( 'costum' ) ) {
        echo '<h4>Bedankt voor het aanmelden voor de Instagram cursus.</h4>';
        echo '<p>Bij het aanmelden heb je je Instagram gebruikersnaam moeten invullen. Als je dit niet hebt gedaan, stuur deze dan zo snel als mogelijk naar ons toe als reactie op de deze e-mail, zodoende weten wij welke Instagram gebruiker wij moeten accepteren.</p>
        <p>Je gaat een online cursus doen die volledig via Instagram te volgen is. Je krijgt één jaar lang toegang tot deze Instagram cursus.</p>
        <p>Om de cursus te kunnen volgen vragen we je het volgende te doen:</p>
        <ol>
            <li>Volg onze cursuspagina op Instagram: <a href="https://instagram.com/ehboviva.online?igshid=NzZlODBkYWE4Ng==">ehboviva.online</a></li>
            <li>Wij accepteren je verzoek binnen 48 uur</li>
            <li>Vanaf nu heb je één jaar lang toegang tot ons Instagram account en kan je dus op elk moment de cursus openen en doornemen</li>
        </ol>
        <p>Veel lees en kijk plezier, succes!</p>';
    }
}

现在我的代码已经完成，因此它会与处理邮件一起发送。但我只想发送自定义电子邮件。或者可以将处理邮件的收件人更改为客户邮件以外的其他收件人。但是当我关闭处理邮件时，它也不会发送。当我更改收件人的邮件时，它会将两封邮件发送到该地址。

我应该改变什么？

附注 我已经删除了很多代码，否则由于垃圾邮件检测，我无法发布此内容。因此，如果有人错过了什么，请通知我。

您的代码中存在一些错误和遗漏的内容......

我修改了你的代码。

我已将您的“costum”状态重命名为更明确的内容（“instacursus”），并添加了第二个自定义状态“custom”，这样您就可以看到如何添加多个状态并保持紧凑的代码......

我添加了一个挂钩函数来禁用默认的“处理”通知。

尝试以下操作：

// register a custom post status for WooCommerce Orders
add_action( 'init', 'register_custom_post_status', 20 );
function register_custom_post_status() {
    register_post_status( 'wc-instacursus', array(
        'label'                     => _x( 'Instagram cursus', 'Order status', 'woocommerce' ),
        'public'                    => true,
        'exclude_from_search'       => false,
        'show_in_admin_all_list'    => true,
        'show_in_admin_status_list' => true,
        'label_count'               => _n_noop( 'Instagram cursus <span class="count">(%s)</span>', 'Instagram cursus <span class="count">(%s)</span>', 'woocommerce' )
    ) );

    register_post_status( 'wc-custom', array(
        'label'                     => _x( 'Custom', 'Order status', 'woocommerce' ),
        'public'                    => true,
        'exclude_from_search'       => false,
        'show_in_admin_all_list'    => true,
        'show_in_admin_status_list' => true,
        'label_count'               => _n_noop( 'Customs <span class="count">(%s)</span>', 'Custom <span class="count">(%s)</span>', 'woocommerce' )
    ) );
}

// Adding custom statuses to order edit pages dropdown
add_filter( 'wc_order_statuses', 'custom_wc_order_statuses' );
function custom_wc_order_statuses( $order_statuses ) {
    $order_statuses['wc-instacursus'] = _x( 'Instagram cursus', 'Order status', 'woocommerce' );
    $order_statuses['wc-custom']      = _x( 'Custom', 'Order status', 'woocommerce' );
    return $order_statuses;
}


// Adding custom statuses to admin order list bulk dropdown
add_filter( 'bulk_actions-edit-shop_order', 'custom_dropdown_bulk_actions_shop_order', 20, 1 );

    return $actions;

// Removing default email notification for 'processing' status (from pending)
add_action( 'woocommerce_email', 'unhook_pending_to_processing_email_notification' );

代码位于子主题的functions.php 文件中（或插件中）。已测试并有效。
