由于某种原因，当我尝试在引导模式中使用我的表单时，它不起作用。我怀疑这与PHP有关，但我不完全确定。
当我点击表单上的提交按钮时，问题发生了。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，这是在模态中。
到目前为止我写的是:
<?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])) {
?>

模态工作得很好，它只是表单没有提交/执行php代码。
任何和所有的帮助感谢!
编辑:有人告诉我，虽然不是W3C有效的，但如果您想让脚本自己启动，则不需要操作标记。也只是从(根据http://www.w3schools.com/tags/att_form_action.asp表单标签是不需要在HTML5:O)，所以
<form action=<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?> method="post">
与
相同<form method="post">
可能的解决方案:
1)"表单"标签中没有指定动作?
也许你应该改变<button type="submit">
<input type="submit" name="submit" value="Submit form">
3)尝试添加这段代码，看看是否真的没有post数据，因为$_POST['submit']没有指定…
if ($_SERVER['REQUEST_METHOD']=='POST') {
echo "there's a post submitted";
}
