Contact form throws errors when sending an email. - php

Question

I am developing a contact form for sending an email to user data,but its not working.
Code:
<?php
if ($_POST["email"]<>'') {
$ToEmail = 'youremail#site.com';
$EmailSubject = 'Site contact form';
$mailheader = "From: ".$_POST["email"]."\r\n";
$mailheader = "Reply-To: ".$_POST["email"]."\r\n";
$mailheader = "Content-type: text/html; charset=iso-8859-1\r\n";
$MESSAGE_BODY = "Name: ".$_POST["name"]."";
$MESSAGE_BODY = "Email: ".$_POST["email"]."";
$MESSAGE_BODY = "Comment: ".nl2br($_POST["comment"])."";
mail($ToEmail, $EmailSubject, $MESSAGE_BODY, $mailheader) or die ("Failure");
?>
Your message was sent
<?php
} else {
?>
<form action="mail.php" method="post">
<table width="400" border="0" cellspacing="2" cellpadding="0">
<tr>
<td width="29%" class="bodytext">Your name:</td>
<td width="71%"><input name="name" type="text" id="name" size="32"></td>
</tr>
<tr>
<td class="bodytext">Email address:</td>
<td><input name="email" type="text" id="email" size="32"></td>
</tr>
<tr>
<td class="bodytext">Comment:</td>
<td><textarea name="Comment" cols="45" rows="6" id="Comment" class="bodytext"></textarea></td>
</tr>
<tr>
<td class="bodytext"> </td>
<td align="left" valign="top"><input type="submit" name="Submit" value="Send"></td>
</tr>
</table>
</form>
<?php
};
?>
It throws an errors like:
Undefined index: commen in line 10.
header missing in line 11.

Answer 1

Here are some mistakes on your code..
1.at the line no 2 change the code from (i don't know why you didn't mention about this error)
if ($_POST["email"]<>'') {
to
if (isset($_POST["email"]) && $_POST["email"]<>'') {
2.change the name of the textarea from "Comment" to "comment"
and finally follow the instruction from the previous answers of this post to solve the "header missing" problem.
something like
$mailheader = "From: ".$_POST["email"]."\r\n";
$mailheader .= "Reply-To: ".$_POST["email"]."\r\n";
$mailheader .= "Content-type: text/html; charset=iso-8859-1\r\n";

Answer 2

As everybody told your first mistake, I am not going to repeat it but another mistake is:
You should join the mail headers and mail body:
Your previous code:
$mailheader = "From: ".$_POST["email"]."\r\n";
$mailheader = "Reply-To: ".$_POST["email"]."\r\n";
$mailheader = "Content-type: text/html; charset=iso-8859-1\r\n";
$MESSAGE_BODY = "Name: ".$_POST["name"]."";
$MESSAGE_BODY = "Email: ".$_POST["email"]."";
$MESSAGE_BODY = "Comment: ".nl2br($_POST["comment"])."";
New Code:
$mailheader = "From: ".$_POST["email"]."\r\n";
$mailheader .= "Reply-To: ".$_POST["email"]."\r\n";
$mailheader .= "Content-type: text/html; charset=iso-8859-1\r\n";
$MESSAGE_BODY = "Name: ".$_POST["name"]."";
$MESSAGE_BODY .= "Email: ".$_POST["email"]."";
$MESSAGE_BODY .= "Comment: ".nl2br($_POST["comment"])."";
Look at the dots given before the equalto signs.

Answer 3

see you need to concatenate the mailHeader var same goes for body message
$mailheader = "From: ".$_POST["email"]."\r\n";
$mailheader .= "Reply-To: ".$_POST["email"]."\r\n";
$mailheader .= "Content-type: text/html; charset=iso-8859-1\r\n";

Answer 4

You have done the two mistakes.
In form you have given name="Comment" for please give name="comment" or $_POST["comment"] to $_POST["Comment"]
put the . after mail header.like
$mailheader = "From: ".$_POST["email"]."\r\n";
$mailheader .= "Reply-To: ".$_POST["email"]."\r\n";
$mailheader .= "Content-type: text/html; charset=iso-8859-1\r\n";
$MESSAGE_BODY = "Name: ".$_POST["name"]."";
$MESSAGE_BODY .= "Email: ".$_POST["email"]."";
$MESSAGE_BODY .= "Comment: ".nl2br($_POST["comment"])."";

Answer 5

you are getting this error 10th line because you are using $_POST["comment"]" but in the form you have written id="Comment". To remove the error take care of upar and lower case in the both places..
Thank you.
