Question

我的代码更不用说了：

<body>
    <!-- Signup Form -->
        <form id="signup-form" method="post" action="">
            <input type="email" name="email" id="email" placeholder="Email Address">
            <input type="submit" value="Sign Up" name="submit">
        </form>


    <!-- Scripts -->
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
        <!--[if lte IE 8]><script src="assets/js/ie/respond.min.js"></script><![endif]-->
        <script src="assets/js/main.js"></script>

</body>

<?php 
echo "<script type='text/javascript'>alert('php loads');</script>";
if(isset($_POST['submit'])){
echo "<script type='text/javascript'>alert('enter if');</script>";
$to = "test@test.com"; // this is your Email address
$from = $_POST['email']; // this is the sender's Email address
$subject = "Form submission";
$message = "Test";
$headers = "test@test.com";

mail($to,$subject,$message,$headers);
// You can also use header('Location: thank_you.php'); to redirect to     another page.
}
?>

我将JS警报作为一切符合预期的标志。第一个警报出现在页面加载，因此它不是PHP问题。但是，当我提交表单时，不会显示第二个警报，也不会发送电子邮件。

我错过了什么吗？

Answer 1

将其添加到页面顶部：

// Should show an empty array
var_dump($_POST);

if(isset($_POST['submit'])){

    var_dump('Form was submitted');

    // Should show an array with your submitted values in
    var_dump($_POST);

}

Answer 2

我认为总是设置

$_POST。你需要检查它是否为空。 if(!empty($_POST['submit'])

Answer 3

毕竟代码工作正常。我没有在问题中包含的外部JS脚本在某种程度上干扰了表单。

感谢您的帮助

Answer 4

似乎您的代码正常
在另一个浏览器中尝试它左右它对我有用，因为它是

isset（$ _ POST ['submit']）不适用于表单提交
