这个问题在这里已有答案：
我有一个网站，其中我只想要一个联系表单，它将接收用户的评论，然后将电子邮件发送给我。我有以下HTML代码：
<form action="emailform.php" method="post" name="contactform" role="form">
<div class="row">
<div class="col-md-5">
<div class="form-group left-inner-addon">
<span class="glyphicon glyphicon-user"></span>
<input name="name" type="text" class="form-control" placeholder="Name" required>
</div>
<div class="form-group left-inner-addon">
<span class="glyphicon glyphicon-envelope"></span>
<input name="email" type="email" class="form-control" placeholder="Email" required>
</div>
<div class="form-group left-inner-addon">
<span class="glyphicon glyphicon-earphone"></span>
<input name="telephone" type="tel" class="form-control" placeholder="Phone" required>
</div>
</div>
<div class="col-md-7">
<div class="form-group left-inner-addon">
<span class="glyphicon glyphicon-comment"></span>
<textarea name="message" rows="6" class="form-control" placeholder="Message..."></textarea><br>
<a><button type="submit" class="btn btn-primary" value="Submit">Send</button></a>
<button type="reset" class="btn btn-default right">Reset</button>
</div>
</div>
</div> <!-- row -->
</form>
我在这里有php代码“emailform.php”：
<?php
if(isset($_POST['submit'])) {
// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "[email protected]";
$email_subject = "PILLAR 360 Inquiry";
function died($error) {
// your error code can go here
echo "We are very sorry, but there were error(s) found with the form you submitted. ";
echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
die();
}
// validation expected data exists
if(!isset($_POST['name']) ||
!isset($_POST['email']) ||
!isset($_POST['telephone']) ||
!isset($_POST['comments'])) {
died('We are sorry, but there appears to be a problem with the form you submitted.');
}
$name = $_POST['input_name']; // required
$email_from = $_POST['input_email']; // required
$telephone = $_POST['input_tel']; // not required
$comments = $_POST['message']; // required
$error_message = "";
$email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email_from)) {
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';
}
$string_exp = "/^[A-Za-z .'-]+$/";
if(!preg_match($string_exp,$name)) {
$error_message .= 'The name you entered does not appear to be valid.<br />';
}
if(strlen($comments) < 2) {
$error_message .= 'The Comments you entered do not appear to be valid.<br />';
}
if(strlen($error_message) > 0) {
died($error_message);
}
$email_message = "Form details below.\n\n";
function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}
$email_message .= "Name: ".clean_string($name)."\n";
$email_message .= "Email: ".clean_string($email_from)."\n";
$email_message .= "Telephone: ".clean_string($telephone)."\n";
$email_message .= "Comments: ".clean_string($comments)."\n";
// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);
?>

当我使用联系表单发送电子邮件时，我只是加载了空白页面并且电子邮件没有被发送...因此错误代码未显示且成功行未显示..
提前致谢。
需要为提交按钮添加名称
<button type="submit" name="submit" class="btn btn-primary" value="Submit">Send</button>
还要更改部分代码，如下所示
// validation expected data exists
if(!isset($_POST['name']) ||
!isset($_POST['email']) ||
!isset($_POST['telephone']) ||
!isset($_POST['message'])) {
died('We are sorry, but there appears to be a problem with the form you submitted.');
}
$name = $_POST['name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // not required
$comments = $_POST['message']; // required
希望这些更改可以解决您的代码问题。
自从我查看PHP以来已经有一段时间了 - 所以这可能不是问题 - 但在你的表单中 - 你的提交按钮有一个value="Submit" - 即：大写 - 但在你的php页面 - 它正在寻找“提交”即 - 不是资本：
if(isset($_POST['submit'])) {...
因此它缺少php页面中的错误处理块。
您需要更改html或php以确保两者相同
if(isset($_POST['Submit'])) {...
此外 - 您的表单输入名称似乎与您在php页面中使用的POST值不匹配
$name = $_POST['input_name']; // required
$email_from = $_POST['input_email']; // required
$telephone = $_POST['input_tel']; // not required
$comments = $_POST['message']; // required
您只在表单中输入“name”，“email”等
$name = $_POST['name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // not required
$comments = $_POST['message']; // required
在表单标记后面的HTML文件中添加以下代码行：
<input type="hidden" name="action" value="send">
并在您的PHP文件更改：
if(isset($_POST['submit'])) {...
至
if(isset($_POST['action']) && $_POST['action'] === 'send') {...
希望这可以帮助。
