Headers already sent Error

Hello Dp members,

I have created a php script for contact us form & script is as follows:

<?php
if(isset($_POST['sbtnSubmit']))
{
	$to = "webmaster@website.com";
	$subject = "Email Subject";
	$message = "Message \n\nName: ".$_POST['txtName']."\n\nE-mail Address: ".$_POST['txtEmail']."\n\nMessage: ".$_POST['taMessage'];
	$headers = 'From: website@No-Reply.com'."\r\n".'Reply-To: website@No-Reply.com'."\r\n".'X-Mailer: PHP/'.phpversion();
	mail($to, $subject, $message, $headers);
	header('Location:thanks.html'); // This is line number 9
	exit;
}

?>

PHP:

I am getting emails when I submit this form but after submission I want to redirect my website to page "thanks.html" but by some reason its not working & I am facing follwing warning:

Warning: Cannot modify header information - headers already sent by (output started at /home/content/o/d/x/odxfusion1/html/test/contact.php:1) in /home/content/o/d/x/odxfusion1/html/test/contact.php on line 9

I know, I am sending headers already but how I can redirect my website from "contact.php" page to "thanks.html" page without any error or warning.

Here is the complete code for this form (HTML form + PHP)

<?php
if(isset($_POST['sbtnSubmit']))
{
	$to = "webmaster@website.com";
	$subject = "Email Subject";
	$message = "Message \n\nName: ".$_POST['txtName']."\n\nE-mail Address: ".$_POST['txtEmail']."\n\nMessage: ".$_POST['taMessage'];
	$headers = 'From: website@No-Reply.com'."\r\n".'Reply-To: website@No-Reply.com'."\r\n".'X-Mailer: PHP/'.phpversion();
	mail($to, $subject, $message, $headers);
	header('Location:thanks.html'); // This is line number 9
	exit;
}

?>

<form name="frmContact" action="contact.php" method="post">
<table>
<tr>
<td><sup>*</sup>Name:</td>

<td width="245"><input type="text" name="txtName" id="txtName" value="" size="25" /></span></td>
</tr>

<tr>
<td><sup>*</sup>Email:</td>

<td><input type="text" name="txtEmail" id="txtEmail" value="" size="25" /></td>
</tr>

<tr>
<td><sup>*</sup>Your Message:</td>

<td><textarea name="taMessage" rows="5" cols="30"></textarea></td>
</tr>
<tr>
<td></td>
<td><input type="submit" name="sbtnSubmit" value="Submit" /></td>
</tr>
</table>
</form>

PHP:

Any help will be appreciated.

Thanks in advance,

Jimmy

 

Try to put html in php's echo command. like: "echo 'your html here';"

 

Cannot modify header information mean there is an text after the header page
please make sure the header is send before any thing
and use @mail($to, $subject, $message, $headers);

 

i mean
<?php
if(isset($_POST['sbtnSubmit']))
{
$to = "webmaster@website.com";
$subject = "Email Subject";
$message = "Message \n\nName: ".$_POST['txtName']."\n\nE-mail Address: ".$_POST['txtEmail']."\n\nMessage: ".$_POST['taMessage'];
$headers = 'From: '."\r\n".'Reply-To: '."\r\n".'X-Mailer: PHP/'.phpversion();
mail($to, $subject, $message, $headers);
header('Location:thanks.html'); // This is line number 9
exit;
}

?>
must be the first thing in the page
not in the form

 

Yes, My Php coding is on the top of the page & HTML is under PHP coding....

 

Did you try what I told you?

 

Put ob_start() at the very top of the page inside php tags.

 

The proper way of avoiding headers already sent error is to make sure
1. You're not using echo or print before the header function
2. There is no html or whitespace before the header function outside the php tags(you can use as much space inside <?php and ?>)

If you can't avoid either of the above, use ob_start at the top of the page.
