php - 防止在 Woocommerce 中多次处理数据谢谢钩子

问题描述

我有一个代码将订单数据发送到外部交付服务，在那里创建一个新订单。我注意到，如果您重新加载“谢谢”页面，代码将再次运行并发送相同的信息。结果：在支持服务中创建了几个相同的订单。我应该在代码中添加什么以免发生这种情况？

add_action('woocommerce_thankyou', 'send_order_to_delivery');
function send_order_to_delivery( $order_id ){
    // Get an instance of the WC_Order object
    $order = wc_get_order( $order_id );

    $order_data = $order->get_data();

    $order_id = $order_data['id'];

    // Send data
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "https://app.example.com/api/index.php?new_order");
    curl_setopt($ch, CURLOPT_FAILONERROR, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $result = curl_exec($ch);
    curl_close($ch);

    $decoded = (array) json_decode($result);

    // Output
    if( isset($decoded['result']) && $decoded['result'] == 'success' && isset($decoded['order_id']) && !empty($decoded['order_id']) ){
        update_post_meta( $order_id, 'delivery_order_id', esc_attr( $decoded['order_id'] ) );
    }
}

解决方案

尝试以下操作，我们检查订单元数据中是否已经存在某些值'delivery_order_id' meta_key，避免执行此任务两次或更多次：

add_action('woocommerce_thankyou', 'send_order_to_delivery');
function send_order_to_delivery( $order_id ){
    // Checking if this has already been done avoiding reload
    if( get_post_meta( $order_id, 'delivery_order_id', true ) ) 
        return; // Exit if already processed

    // Get an instance of the WC_Order object
    $order_data = $order->get_data();

    $order_id = $order_data['id'];

    // Send data
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "https://app.example.com/api/index.php?new_order");
    curl_setopt($ch, CURLOPT_FAILONERROR, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $result = curl_exec($ch);
    curl_close($ch);

    $decoded = (array) json_decode($result);

    // Output
    if( isset($decoded['result']) && $decoded['result'] == 'success' && isset($decoded['order_id']) && !empty($decoded['order_id']) ){
        update_post_meta( $order_id, 'delivery_order_id', esc_attr( $decoded['order_id'] ) );
    }
}

代码位于活动子主题（或活动主题）的 function.php 文件中。它应该可以彻底解决您的问题。
