在.PHP

Question

我正在尝试添加一条消息，在邮件发送后显示消息已成功分派，但我不知道如何将其插入PHP请求部分。我预先烘焙了html但我无法链接它。我应该参与JQuery吗？

  if ($conn->connect_error) {
        array_push($errors, "We are having problems at the moment. PLease try again later");
    } 

    if (empty($errors)) {
        // prepare mysql query and bind variables
        $query = "INSERT INTO contact_requests (firstname, lastname, email, company, requested_services, `message`) 
                            VALUES (?, ?, ?, ?, ?, ?)";
        $stmt = $conn->prepare($query);
        if (!$stmt) {
            array_push($errors, "We are having problems at the moment. PLease try again later");
        }
    }

    if (empty($errors)) {
        if(!$stmt->bind_param("ssssss", $name, $last_name, $email, $company, $services, $message)) {
            array_push($errors, "We are having problems at the moment. PLease try again later");
        }
    }

    if (empty($errors)) {
        if(!$stmt->execute()) {
            array_push($errors, "We are having problems at the moment. PLease try again later");
        }
    }
}

function sanitize_input($data)
{
    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data);

    return $data;
}

HTML

    <div id="success_message" style="width:100%; height:100%; display:none;">
        <h3>Sent your message successfully!</h3>
    </div>
