我试图将SMS API与woo商务整合为每一个新订单，但我不确定我做错了什么。我的任务是发送短信给客户，当他们下订单与支付网关C. O. D（货到付款）.下面是我使用的代码。谁能告诉我我做错了什么？
add_action('woocommerce_thankyou', 'custom_process_order', 10, 1);
function custom_process_order($order_id) {
$order = new WC_Order( $order_id );
$customer_id = $order->user_id;
$billing_phone = get_user_meta( $customer_id, 'billing_phone', true );
$data="userid=[userid]&pwd=[password]&msg=[msg]&mobileno=".$billing_phone;
$jsonurl = curl_init('http://b2bsms.telecard.com.pk/SMSPortal/Customer/ProcessSMS.aspx');
$json = curl($jsonurl);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($json);
echo $result;
curl_close($json);
return $order_id;
}
错误消息是
PHP Fatal error: Call to undefined function curl()
php中没有函数curl，对curl\u exec的调用运行http调用。您可以删除行$json=curl（$jsonurl）$json或$ch的任何地方使用句柄$jsonurl：
$jsonurl = curl_init('http://b2bsms.telecard.com.pk/SMSPortal/Customer/ProcessSMS.aspx');
curl_setopt($jsonurl, CURLOPT_POST, true);
curl_setopt($jsonurl, CURLOPT_POSTFIELDS, $data);
curl_setopt($jsonurl, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($jsonurl);
echo $result;
