我在Python編程方面有一些以前的經驗，但是我被要求爲某人構建一個網頁，所以我試圖用一個引導框架，html和php來構建一個基本頁面）。用PHP驗證掙扎
一切似乎都是從沒有驗證的訂閱表單中完全按照需要appart，所以我認爲這是最好的impliment一些，但形式似乎並沒有反應，並仍然允許腳本完成併發送電子郵件甚至與一個空的表格。
這是因爲窗體是'Modal'嗎？我在這方面還是一個新手，我很抱歉如果這已被覆蓋，但我找不到幫助我的答案。
我附上了模態表格html和php代碼。命名
<!-- Modal form -->
<div class="modal fade" id="Subscribe" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">Subscribe for updates!</h4>
</div>
<div class="modal-body">
<div class="container-fluid">
<form method="post" action="Submit.php">
<div class="row">
<div class="col-xs-12">

<span class="input-group-addon" id="first">First Name</span>
<input type="text" class="form-control" placeholder="John" name="first" aria-describedby="First-Name">

文件「Submit.php
<?php
// define variables and set to empty values

function test_input($data) {
$data = trim($data);
$data = stripslashes($data);

return $data;
}
if (isset($_POST['submit'])) {
if (empty($_POST["email"])) {

} else {
$email = test_input($_POST["email"]);
// check if e-mail address is well-formed
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {

if (!preg_match("/^[a-zA-Z ]*$/",$last_name)) {
$lastErr = "Only letters and white space allowed";
}
}
$notes = test_input($_POST["notes"]); // this is the senders message
$to = "[email protected]"; // this is your Email address
$subject = "Website subscription from " . $first_name . " " . $last_name; //Subject line
$message = "First name: " . $first_name . "<br>" . "Surname: " . $last_name . "<br>" . "Email: " . $from . "<br>" . "Notes: " . $notes;
$headers = "From: " . $from . "\r\n";
// $headers .= "CC: [email protected]\n"; option to CC
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
mail($to,$subject,$message,$headers);
header('Location: ./index.html#Thanks'); // redirect back to main page with 'Thanks' Modal open
}
?>
我將非常感謝您的幫助！
編輯：
只是櫃面有人想知道怎麼我完全結束了，我需要的是：@leepowers答案是朝着正確的方向邁出了一大步，這使我能夠檢查是否有任何錯誤，並防止發送電子郵件，如果有的話，然後我瞭解了'會話'，我將錯誤存儲在會話中（可能以非常混亂的方式），因此我可以在返回到表單時重用它們。
// Gather all errors into an array
$errors = array($fromErr, $firstErr, $lastErr);
// Remove any empty error messages from the array
$errors = array_filter($errors);
// An array with more than zero elements evaluates `true` in a boolean context
if ($errors) {
$_SESSION["fromErr"] = $fromErr;
$_SESSION["firstErr"] = $firstErr;
$_SESSION["lastErr"] = $lastErr;
die(header('Location: ./index.html#Subscribe'));
} else { // send email
在我的HTML頁面，我有一些JS指導「重定向」到一個模式：
<script>
$(document).ready(function() {
if(window.location.href.indexOf('#Thanks') != -1) {
$('#Thanks').modal('show');
} else if(window.location.href.indexOf('#Subscribe') != -1) {
$('#Subscribe').modal('show');
}
});
</script>
，現在我的每個輸入在我的形式有一個專門的錯誤：
<div class="input-group" style="margin-bottom: 5px;">
<span class="input-group-addon" id="email">Email</span>
<input type="email" class="form-control" placeholder="[email protected]" name="email" aria-describedby="Email">
<span class="input-group-addon error" style="color: red">* <?php echo $_SESSION["fromErr"];?></span>
謝謝大家的幫助。
你對'$ lastErr'或'$ firstErr'沒做任何事情，所以電子郵件只是發送。嘗試添加一個條件，要求在郵件（$ to，$ subject，$ message，$ headers）;'之前這兩個條件都是空的。 – chris85
我不確定這是否是別人的做法，但我通常會將所有錯誤追加到單個數組中，然後在檢查多個條件時檢查是否發生了任何錯誤，只需執行if（count（$ errors）> 0 ）{handleError（）; } else {doSomething（）; }' – Mike
另外，'test_input（）'到底做了什麼？ – Mike
