我试图创建一个html和php联系人表单，但它似乎不工作。我相信这是一个简单的答案，但我想不出来。
谁能告诉我我哪里做错了?它不会重定向到mail.php页面。 <div class="col-lg-8">
<form action="mail.php" class="form-horizontal" id="contactForm" name="contactForm" method="post" >
<div class="form-group" >
<label for="first-name" class="col-lg-2">First name</label>
<div class="col-lg-10">
<input type="text" class="form-control" id="first-name" name="first-name" placeholder="What your mam calls you ">
</div>
</div><!--end form group-->
<div class="form-group">
<label for="last-name" class="col-lg-2">Last name</label>
<div class="col-lg-10">
<input type="text" class="form-control" id="last-name" name="last-name" placeholder="What your army buddies call you">
</div>
</div><!--end form group-->
<div class="form-group">
<label for="email" class="col-lg-2">Email</label>
<div class="col-lg-10">
<input type="text" class="form-control" id="email" name="email" placeholder="Enter your email address, we won't send you junk mail">
</div>
</div><!--end form group-->
<div class="form-group">
<label for="website" class="col-lg-2">Your current website</label>
<div class="col-lg-10">
<input type="text" class="form-control" id="website" name="website" placeholder="If you have one.">
</div>
</div><!--end form group-->
<div class="form-group">
<label for="message" class="col-lg-2">Any Message</label>
<div class="col-lg-10">
<textarea name="message" id="message" name="message" class="form-control"
cols="20" rows="10" placeholder="Maybe tells us a bit about your business. I'll start, mine is web development. ;)"></textarea>
</div>
</div><!--end form group-->
<div class="form-group">
<div class="col-lg-10 col-lg-offset-2">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</div>
</form>
</div>
</div><!--end of row-->
</section>
</div>
mail.php
<html>
<body>
<?php
if(isset($_POST['submit'])){
$to = "info@wonderfulwebsites.ie"; // this is your Email address
$from = $_POST['email']; // this is the sender's Email address
$f_name = $_POST['first_name'];
$s_name = $_POST['last_name'];
$subject = "Form submission";
$subject2 = "Copy of your form submission";
$message = $f_name . " " . $s_name . " wrote the following:" . "'n'n" . $_POST['message'] "'n" $website = $_POST['website'];
$message2 = "Here is a copy of your message " . $f_name . "'n'n" . $_POST['message'];
$headers = "From:" . $from;
$headers2 = "From:" . $to;
mail($to,$subject,$message,$headers);
mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
echo "Mail Sent. Thank you " . $f_name . ", we will contact you shortly.";
// You can also use header('Location: thank_you.php'); to redirect to another page.
// You cannot use header and echo together. It's one or the other.
}
?>
</body>
</html>
修改如下:
<button type="submit" class="btn btn-primary">Submit</button>
:
<input type="submit" class="btn btn-primary" value="Submit" />
