提交變量永遠不會在您的窗體中設置。注意，該按鈕現在是提交類型提交的名稱屬性爲submit的輸入。
另外你的其他表單變量沒有設置。
你永遠不會迴應任何事情。所以我在你的最後一個條件中迴應。
如果您希望表單在提交表單後顯示，您需要將index.html重命名爲index.php，並在頂部包含contact.php。見下文。
如果您明白地檢查$ _POST變量是否爲真，PHP將拋出E_NOTICE錯誤。所以最好將變量包裝到isset（）中（就像這個變量集合）函數一樣。見下文。
我重構了，以防止E_NOTICE錯誤並評論這些更改。
contact.php
<?php
if (isset($_POST["submit"])) {
$error = [];
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
/*$human = intval($_POST['human']); */
$from = 'Geofrey Zellah';
$to = '[email protected]';
$subject = 'Message from Geofrey Zellah ';
$body = "From: $name\n E-Mail: $email\n Message:\n $message";
// Check if name has been entered
if (!isset($_POST['name']) || strlen($_POST['name']) === 0) {
$error['name'] = 'Please enter your name';
}
// Check if email has been entered and is valid
if (!isset($_POST['email']) || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
$error['email'] = 'Please enter a valid email address';
}
//Check if message has been entered
if (!isset($_POST['message']) || strlen($_POST['name']) === 0) {
$error['message'] = 'Please enter your message';
}
/*
//Check if simple anti-bot test is correct
if ($human !== 5) {
$errHuman = 'Your anti-spam is incorrect';
} */
// If there are no errors, send the email
if (empty($error)) {
if (mail ($to, $subject, $body, $from)) {
$result='<div class="alert alert-success">Thank You! I will be in touch</div>';
} else {
$result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later</div>';
}
}
}
?>

UPDATE
如果你不想提交時重新加載頁面g表單，您將需要一些jQuery ajax操作並更改您的HTML和PHP文件。
首先刪除之前，我們添加了index.php文件的第一行：
<?php include 'contact.php';?><!-- Remove this one -->
你不想被包含的文件做，而是將數據發送給它。
接下來編輯HTML文件並在HTML下包含jQuery庫（在HTML下執行JS東西的常見做法）。然後相應地改變你的PHP文件。
因此新的HTML：
<div class="container">
<div class="row">
<div class="col-md-6 col-md-offset-3" id="offer">
<h2 id="form"> LET'S WORK ? </h2>
</div>
<div class="col-md-6 col-md-offset-3">
<form role="form" name="contact" method="post">
<div class="form-group">
<input name="name" type="text" class="form-control" placeholder="Enter Your Name" value="test">
</div>
<div class="form-group">
<input name="email" type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter Your Email" value="[email protected]">
</div>
<div class="form-group">
<textarea name="message" class="form-control" id="textarea1" rows="3" placeholder="Enter Your Message here">test </textarea>
</div>
<div class="form-group">
<input name="submit" type="submit" class="default-submit btn btn-large propClone bg-fast-pink btn-circle font-weight-300 text-white tz-text" value="SEND MESSAGE">
</div>
<div class="form-group" id="result">
</div>
</form>
</div>
</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){ // launch when DOM is fully loaded
$('form[name="contact"]').submit(function(event){ // fire when you hit submit
event.preventDefault(); // prevent default form submission since you want to send data via ajax
$('#result').html('');
$('.alert').remove();
var values = $(this).serialize();
// Post form data to your contact.php script and work with response
$.ajax({
url: "contact.php",
type: "POST",
data: values ,
success: function (response) {
if(response.success) {
$('#result').html('<div class="alert alert-success">'+response.success+'</div>');
}
if(response.error_form) {
$.each(response.error_form, function(key, value) {
$('input[name="'+key+'"]').parent().append('<p class="help-block text-danger">'+value+'</p>');
});
}
if(response.error_mail) {
$('#result').html('<div class="alert alert-danger">'+response.error_mail+'</div>');
}
},
error: function(jqXHR, textStatus, errorThrown) {
console.log(textStatus, errorThrown);
}
});
});
});
</script>
最後更改的PHP：
<?php
ini_set('display_errors',0);
$result = [];
// Check if name has been entered
if (!isset($_POST['name']) || strlen($_POST['name']) === 0) {
$result['error_form']['name'] = 'Please enter your name';
}
// Check if email has been entered and is valid
if (!isset($_POST['email']) || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
$result['error_form']['email'] = 'Please enter a valid email address';
}
//Check if message has been entered
if (!isset($_POST['message']) || strlen($_POST['message']) === 0) {
$result['error_form']['message'] = 'Please enter your message';
}
/*
//Check if simple anti-bot test is correct
if ($human !== 5) {
$errHuman = 'Your anti-spam is incorrect';
} */
// If there are no errors, send the email
if (empty($result['error_form'])) {
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
/*$human = intval($_POST['human']); */
$from = 'Geofrey Zellah';
$to = '[email protected]';
$subject = 'Message from Geofrey Zellah ';
$body = "From: $name\n E-Mail: $email\n Message:\n $message";
if (mail ($to, $subject, $body, $from)) {
$result['success']='Thank You! I will be in touch';
} else {
$result['error_mail']='Sorry there was an error sending your message. Please try again later';
}
}
header('Content-type: application/json'); // tell browser what to expect
echo json_encode($result); // encode array to json object so javascript can work with it
我做了這樣一個複雜的例子，因爲許多人決定去阿賈克斯，一旦他們成功地發送定期形式，但注意，頁面重新加載;）
http://php.net/manual/en/function.error-reporting.php，你會看到很多未定義的索引通知，由於沒有名稱屬性。 –
@fred -li我沒有收到任何錯誤我只是點擊提交後纔得到白屏，所以我不知道我的代碼有什麼問題謝謝 –
@ Fred-ii-：我想，這個問題不是重複的你上面提到的是什麼。 （你所標記的與此無關） –
