[SOLVED] Output Starting on Line 1 - "<?php" is the only thing on line 1

[14pulsars]

Hi folks,

 

I'm having some problems with a script I'm writing. I'm trying to use a session to store POST variables for another page, then redirect based on one of the post variables. After the user redirects, they click a few links, and come back to the redirecting page, except they see the content this time, with some form fields pre-populated using the session info.

 

Here are the error codes I get:

 

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/dir/public_html/orderconfirm.php:1) in /home/dir/public_html/orderconfirm.php on line 1

 

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/dir/public_html/orderconfirm.php:1) in /home/dir/public_html/orderconfirm.php on line 1

 

Warning: Cannot modify header information - headers already sent by (output started at /home/dir/public_html/orderconfirm.php:1) in /home/dir/public_html/orderconfirm.php on line 16

 

Here is the code at the top of the page responsible for the work(starting from line 1)

<?php session_start();
if (isset($_POST))
{
if ($_GET['us'] != 'true')
{	
	foreach ($_POST as $key => $value)
		$_SESSION[$key] = $value;

}

for ($i=1;$i<20;$i++)
{
	if(isset($_POST['sku'.$i]))
	{
		if ($_POST['sku'.$i] == "AOI0000")
			header('Location: http://www.sitename.com/bookthankyou.php');
		elseif ($_POST['sku'.$i] == "AOI0004")
			header('Location: http://www.sitename.com/hardcopythankyou.php');
	}
	else
		break;
}
}
?>

 

I thought that the problem would be on line 1, but there is nothing but the opening PHP bracket - no empty space or anything that could cause an issue.

 

Any thoughts on a cause for the problem?

Did you save the file as UTF-8?  If so, there could be a byte order mark (BOM) that you can't see at the beginning of the file.  Some editors have the option to turn it off, so look.  If not, open a hex editor and find it.

Or if you've included the file from another, make sure you haven't already outputted anything

Dreamweaver has the option to include a BOM - I unchecked it, still no go.

Not included anywhere - I just present this page, nothing else.

 

Thanks for your replies, though!

Eww, you use Dreamweaver?  Anyway....try going into a hex editor and manually deleting it.  I suggest XVI32 as your hex editor. =P

NOTEPAD++ ftw :]

Oh, and make sure there isn't a cheeky little space before the <?php

I dropped it into notepad++ as well - no different that the Dreamweaver code view.

Here's what you can do.  Open Notepad (regular ol' Notepad) and just copy and paste your code in:

<?php session_start();
if (isset($_POST))
{
if ($_GET['us'] != 'true')
{	
	foreach ($_POST as $key => $value)
		$_SESSION[$key] = $value;

}

for ($i=1;$i<20;$i++)
{
	if(isset($_POST['sku'.$i]))
	{
		if ($_POST['sku'.$i] == "AOI0000")
			header('Location: http://www.sitename.com/bookthankyou.php');
		elseif ($_POST['sku'.$i] == "AOI0004")
			header('Location: http://www.sitename.com/hardcopythankyou.php');
	}
	else
		break;
}
}
?>

 

And save it.  Try that.  Just copy and paste it from here.

Tried XVI32, removed three small symbols from the start, and it works! Thanks!

Any time. =)
