我正在关注使用 PHP、HTML 和 CSS 创建联系表单的教程。这是我第一次使用 php，我遇到了一些麻烦。教程在这里。当我尝试提交表单以检查错误消息时，似乎没有任何反应。我不知道出了什么问题，并且整天都在努力解决这个问题。任何帮助将不胜感激。该代码用于我一直在处理的完整网站的登录页面。
这是代码的 HTML 和 CSS：

font-size: 12px;
line-height:30px;
color:#777;

width:100%;
margin:0 auto;
position:relative;
}
#contact input[type="text"], #contact input[type="email"], #contact input[type="tel"], #contact input[type="url"], #contact textarea, #contact button[type="submit"] { font:400 12px/16px "Open Sans", Helvetica, Arial, sans-serif; }

if ($_SERVER["REQUEST_METHOD"] == "POST") {
if (empty($_POST["name"])) {

} else {
$name = test_input($_POST["name"]);
// check if name only contains letters and whitespace
if (!preg_match("/^[a-zA-Z ]*$/",$name)) {

}
