引导程序中的表单不起作用..为什么？

出于某种原因，当我尝试在bootstrap模式中使用我的表单时，它不起作用。我怀疑是与PHP有关但我不完全确定。

单击表单上的提交按钮时会出现问题。该文档没有激活应该更新mysql的php，然后将你重定向到另一个页面，而只是刷新当前页面。请记住，这是一种模式。

这是我到目前为止所拥有的：

<?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])) {
?>

模态工作正常，它的形式不是提交/执行php代码。

任何和所有帮助表示赞赏！

编辑： 有人告诉我，虽然不是W3C有效，但如果你想要脚本开始自己，那么动作标签是不必要的。也只是从（根据http://www.w3schools.com/tags/att_form_action.asp学习HTML5中不需要表单标记：O）所以

<form action=<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?> method="post">

与

相同 
<form method="post">

1 个答案:

答案 0 :(得分：2)

可能的解决方案：

1）＆＃34;表格＆＃34;中没有指定任何动作。标记

2）也许你应该改变

<button type="submit">

到

<input type="submit" name="submit" value="Submit form">

3）尝试添加此代码以查看是否确实没有发布数据，因为$ _POST [＆＃39; submit＆＃39;]未指定... 

if ($_SERVER['REQUEST_METHOD']=='POST') {
    echo "there's a post submitted";
}

4）尝试清理PHP代码，使用适当的OO原则/模式来管理表单和数据。
