php - 单击在 WooCommerce 管理员订单列表中显示文本时隐藏自定义操作按钮

Question

我正在创建 woocommerce 插件以通过 WhatsApp 发送订单详细信息。这是我的插件代码

add_filter( 'manage_edit-shop_order_columns', 'dvs_whatsapp_msg_list_column' );
function dvs_whatsapp_msg_list_column( $columns ) {
    $columns['dvs_show_whatsapp'] = 'WhatsApp';
    return $columns;
}
 
add_action( 'manage_shop_order_posts_custom_column', 'dvs_whatsapp_msg_list_column_content' );
function dvs_whatsapp_msg_list_column_content( $column ) {
    global $post;
    if ( 'dvs_show_whatsapp' === $column ) {
        $order = wc_get_order( $post->ID );
        $firstname = $order->get_billing_first_name();
        $lastname = $order->get_billing_last_name();
        $phone = $order->get_billing_phone();
        $ordernum = $order->get_order_number();
        $total = $order->get_total();
        $payment = $order->get_payment_method_title();
        $country = $order->get_billing_country();
        $calling_code = WC()->countries->get_country_calling_code($country);
        $whatsappnum = $calling_code.$phone;

        $msg = 'Hello ' .$firstname. ' ' .$lastname. ', your order #' .$ordernum. ' has been received. The order amount is ' .$total. '. Your payment method is ' .$payment.  '. Please contact us if you have any question regarding your order. Thank you.';
        
echo '<a href="https://wa.me/' .$whatsappnum. '?text=' .urlencode($msg).'" target="blank" class="dvs-whatsapp-btn">Send WhatsApp</a>';
    }
}

这是输出

我希望当店长或管理员点击发送 Whatsapp 链接时，它会隐藏链接并显示消息已发送，以便店长或管理员可以知道此消息的详细信息已发送。

请帮忙。

Javascript 不是实现此目的的方法。您将使用以下内容来隐藏链接并在单击外部链接后显示“消息已发送”:

add_filter( 'manage_edit-shop_order_columns', 'dvs_whatsapp_msg_list_column' );
function dvs_whatsapp_msg_list_column( $columns ) {
    $columns['whatsapp'] = __('WhatsApp', 'woocommerce');
    return $columns;
}

add_action( 'manage_shop_order_posts_custom_column', 'dvs_whatsapp_msg_list_column_content' );
function dvs_whatsapp_msg_list_column_content( $column ) {
    if ( 'whatsapp' === $column ) {
        global $the_order;

        if( ! $the_order->get_meta('_wapp_sent') ) {
            echo '<a href="?post_type=shop_order&send=dvs_whatsapp&order_id=' . $the_order->get_id() .' target="blank" class="dvs-whatsapp button">' . __("Send WhatsApp") . '</a>';
        }
        else {
            echo __("Message sent", "woocommerce");
        }
    }
}

add_action( 'admin_init', 'dvs_redirect_whatsapp_send' );
function dvs_redirect_whatsapp_send() {
    global $pagenow;

    # Check current admin page.
    if ( $pagenow == 'edit.php' && isset($_GET['post_type']) && $_GET['post_type'] == 'shop_order'
    && isset($_GET['send']) && $_GET['send'] == 'dvs_whatsapp' && isset($_GET['order_id']) && $_GET['order_id'] > 0 ) {
        $order = wc_get_order( $_GET['order_id'] );

        $msg = sprintf( __("Hello %s %s, your order #%s has been received. The order amount is %s. Your payment method is %s. %s", "woocommerce"),
            $order->get_billing_first_name(),
            $order->get_billing_last_name(),
            $order->get_order_number(),
            $order->get_total(),
            $order->get_payment_method_title(),
            __("Please contact us if you have any question regarding your order. Thank you.", "woocommerce")
        );

        $whatsapp_num = WC()->countries->get_country_calling_code( $order->get_billing_country() ) . $order->get_billing_phone();

        update_post_meta( $_GET['order_id'], '_wapp_sent', 'true' ); // Mark order as WhatsApp message sent

        wp_redirect( 'https://wa.me/' . $whatsappnum . '?text=' . urlencode($msg) ); // Redirect to WhatsApp sending service
        exit;
    }
}

代码进入事件子主题(或事件主题)的 functions.php 文件。经过测试并有效。
