我写如下
$name="Kumkum";
$email="kumkum@gmail.com";
$phone="3456734567";
$country="India";
$course="Database";
$message="hello i want to read db";
$now = new DateTime();
$datesent=$now->format('Y-m-d H:i:s');
global $wpdb;
$sql = $wpdb->prepare(
"INSERT INTO `wp_submitted_form` (`name`,`email`,`phone`,`country`,`course`,`message`,`datesent`) values ("
$name, $email, $phone, $country, $course, $message, $datesent. ')")';
$wpdb->query($sql);
它不工作......它抛出错误......请帮助我纠正它。
