Php bootstrap中的表单赢得'；不行。。为什么？

出于某种原因，当我尝试在引导模式中使用表单时，它不起作用。我怀疑is和PHP有关，但我不能完全确定

当我单击表单上的“提交”按钮时，问题就出现了。该文档不会激活php，php应该更新mysql，然后将您重定向到另一个页面，而只是刷新当前页面。请记住，这是一个模态

以下是我目前掌握的情况：

<?php
if(basename($_SERVER["PHP_SELF"]) == "header.php"){
    die("403 - Access Forbidden");
}
    $cookie_name = 'showmodal';
    $cookie_value = 'AlreadySawModal';
    setcookie($cookie_name, $cookie_value, time() + (43200), '/'); // 43200 = 12hr
 ?> 
<?php

if (!isset($_COOKIE[$cookie_name])) {
?>

可能的解决办法：

1） “表单”标记中没有指定任何操作

2） 也许你应该换衣服

<button type="submit">

4） 尝试清理PHP代码，使用适当的OO原则/模式管理表单和数据。
