PHP - Missing Something Obvious With Headers Being Sent

Hi all,

It's probably something obvious, but perhaps someone could explain to me what is going on here...

I spent a lot of time this afternoon trying to fix what seemed to be a very odd problem, which involved an image being chucked out like so:

Code: [Select]
<?php
header("Content-Type: image/png");
echo file_get_contents("http://www.example.com/some_image.png");
?>
Except the image was coming out as corrupted, ultimately because I had some white space before this snippet (foolish, I know). The reason it took me so long to diagnose the problem was because I wasn't getting PHP errors (even though they were switched on). As far as the script was concerned, it seems I wasn't sending anything before attempting to modify the headers.

After solving the problem, I put the following little bit of code together, trying to force a header error... And yet I get nothing. It all works, and I get redirected, when I'm sure I shouldn't be. I've run this on a default install of XAMPP, and a configured CentOS server, and the same thing happens on both.

If anyone can explain to me what is going on, I would be most appreciative! There are some inline comments which should help clarify what I mean.

Code: [Select]
<?php

error_reporting(E_ALL);
ini_set("display_errors","1");

?>

<p>Hello! The very existence of this text should really have resulted in the headers being sent... Shouldn't it?</p>
<p>So I'd expect to see a "Headers already sent" message... Shouldn't I?</p>

<?php

// Headers sent?
echo "<p>";
echo "Headers ";

if(!headers_sent()) {
echo "not "; // This "not" does echo out.
}
echo "sent.</p>";

// This WILL start a session (or at least, won't throw an error)
session_start();

// This redirect WILL work, and you will never see the above messages.
header("Location: redirect.php");

// What?!

?>
Thanks!

hello,

I'm using this code:

<?php

  if (isset($_REQUEST['email']))
  {
 $name = $_REQUEST['name'] ;
 $email = $_REQUEST['email'] ;
 $code = $_REQUEST['code'] ;
 $from = $email;
    mail("email@email.com", "Winner request id: $name - code: $code",
    "From:" . $from);
    }
  $headers = "From:" . $from;
  header('Location: index.php?done');
  ?>

And I'm getting:

Code: [Select]
Warning: Cannot modify header information - headers already sent by (output started at /home/site/public_html/config.php:10) in /home/site/public_html/send.php on line 13
This worked before.

Many thanks

Okay, I've read all the rules for Headers...still can't it to execute properly.  At the bottom is my code.  I basically want to check the database, see if the user is already registered, and redirect as appropriate (there is no HTML on my page, no info sent to the browser).  My server doesn't send any error messages.  All I get are white screens. 

Now, if I do the headers_sent()...it tells me that it's sent right after the initial connection with the database. 

The ONLY way I can get it to redirect, is if I put
<?php
header("location:index.php?msg=3");
?>
 at hte very top, but then I can't evalute...which doesn't help me much.

Here is the code (obviously, I have more...but it's sending headers in these lines)


<?php
$connection = mysql_connect("localhost","####","#####");

if (!$connection){
echo mysql_errno().": ".mysql_error()."<br/>";
exit;
}

if(!mysql_select_db("prixaurora")){
echo("Database not found<br>");
}

Hi
I am getting the following php error that is on all my pages and it works fine on the other pages except index.php
Code: [Select]
<?php

Hi I have coded a form, and dependant upon the result I would like to re-direct to a different page. The problem is I am getting the "headers already sent" message..Is there a way around this, I can't use JS re-direction because of accessibility.

E.G:

<?php
//Do stuff with form data
if($result = y){
header(Location: "mysite.php/thankyou.php");
}
else{
header(Location: "mysite.php/error.php");
}
?>

In-fact whilst typing this I have an idea, why not do all of this at the top of the page before headers are sent? I'll go ahead and try it now, in the meantime if anybody knows how or if headers can be sent after output please let me know thanks.

Hi everyone, thanks for reading.

I have live HTTP headers installed on Firefox, hopefully some of you will be familiar with this addon.

I would like to make a php script that is able to do what live http headers does, that is, I'd like to be able to give the script a URL and it will return all the headers.

I know how to use CURLOPT_HEADER and CURLOPT_RETURNTRANSFER but this doesn't quite do what I'm looking for.

For example if I go to :

https://adwords.google.com/o/Targeting/Explorer?__c=1000000000&__u=1000000000&ideaRequestType=KEYWORD_STATS#search.none

with Live HTTP Headers switched on I get the following data under the 'generators' tab

Any help would be great

Hi !

I am currently trying to develop a PHP application in which my server downloads a file and the user can do the same almost simultaneously. I already think about the problem "If the user downloads fastly than the server...", but it's not a problem at this moment.
To do so, I used the header and readfile functions of php. Here is my code :

Code: [Select]
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.$data['name'].'";');
header('Content-Transfer-Encoding: binary');
header('Content-Length: '.$data['size']);
readfile($remoteFile);

I must to use the Content-length header to set the proper size of the file and not the size that is downloaded when the user clicks on the link. However, after some seconds or minutes, download is stopped and I need to restart...
If you think about a solution, even if it didn't use the header(); function, please tell me.

Thank you in advance...

I have an email generated from PHP but it's getting placed in gmails spam folder.  Any idea how to get rid of my old domain from being displayed?  Is this something I do in php or in ubuntu command line?  If I have to change something in ubuntu, how do I edit the olddomainname.

Here are the headers...

Hi,

I have a php email form and in the headers, I just want to add a 2nd email that the form will send to.  I can only get the form to be sent to the first email?  This is the code I currently have:

$headers .= 'From: The Group <me@aol.com>' . "\r\n";
$headers .= 'CC: me2@aol.com'. "\r\n";

Is my code off for the CC email?

Thanks for the help!

Sorry to ask such a "newb" question, but I'm a bit fuzzy on this...

When you get a "Headers Already Sent" error, can that be caused by spaces between your HTML??   

I am having trouble getting my Log-In script to work, and I finally broke down and added Output Buffering to get things working, although a couple of senior members here scolded me in the past as basically saying it was slopping coding to need Output Buffering?!   

Here is my problematic code...
Code: [Select]
<?php
// Initialize a session.
session_start();

// Access Constants.
require_once('config/config.inc.php');
?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<head>
<!-- HTML Metadata -->
<title>My Site - Log In</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="description"

<meta name="keywords"

<link type="text/css" rel="stylesheet" href="css/log_in.css" />
</head>

<body>
<div id="wrapper" class="clearfix">
<div id="inner">
<?php

I have session_start() at the very beginning, and no spaces between my opening PHP and HTML, so the only thing I can figure is the carriage returns within my HTML?!

Thanks,


Debbie

P.S.  Is using Output Buffering really that evil??

Just a quick question.  I'm using the Live HTTP Headers add-on for Firefox that display all the HTTP headers etc.  I'm writing an article on it and want to include a screenshot of it in action.  Are there any headers that I should hide from the reader for security reasons?

Thanks for any help. 

OK you fantastic PHPfreakers I'm not sure how to describe this so I hope you will understand..   I have a predicament where I set the header info to: header('Content-Type: text/html; charset=utf-8'); but later on I have a part of my site that requests an image from somewhere else using getImage() here I need to set header("Content-type: image/jpeg"); in order for the image to show correctly. but this conflicts with the previous page of headers already sent.   so I was looking for a way around this OR maybe can I load them in after the page has loaded? I have tried using Jquery to post with ajax but I don't seem to get any response the alert does not trigger for any conversation with an image.   I have tested all of this and it works as long as I don't put any OUTPUT before triggering the getImage()

<script type='text/javascript'>
	$(document).ready(function(){
		function loadImages(){										
			$.ajax({
			type: "POST",
			url: "/admin/getImage.php",
			data: {token: '<?php echo $token; ?>', chatId: '<?php echo $chat; ?>', uId: '<?php echo $uId; ?>'},
			success: function(data){		
				alert(data);
				$('#img').html(data);
			}
		});
		return false;
		}
	});
</script>

here is part of the messages page that would show the image. (just imagine there was more content etc..)

<?php 
	header('Content-Type: text/html; charset=utf-8'); 
	## OTHER GENERIC STUFF		
	$parser = new Parser($v1, $v2);			
	$convo = $parser->getConvo($token, $id);

	foreach($convo['messageGroups'] as $con)
	{	
		$chat = $con['messageGroupId'];		
			
		$uId = $con['latestMessage']['messageUid'];
		$key = $con['latestMessage']['messageKind'];						
		if($key == '3'){
										
			$image = $parser->getImage($token, $chat, $uId);
			echo $image;
		}
		
	}
?>

here is the function for getImages()

public function getImage($token, $chat, $uId){
	$this->initCURL();
	$chatter = str_replace("{{chat}}", $chat, $this->url['image']);
	$chatter = str_replace("{{uId}}", $uId, $chatter);
			
	$headerData = $this->defaultGETHeader($token);
			
	curl_setopt($this->curl, CURLOPT_URL, $chatter);
	curl_setopt($this->curl, CURLOPT_HTTPHEADER, $headerData);
			
	$output = curl_exec($this->curl);
	$this->closeCURL();
			
	header("Content-type: image/jpeg");
			
	return $output;
}

Hi All,

I am trying to use headers at the end of functions to put the user where they need to be.

header("location: register.php?user_may_exist");

I understand how they work and their qwuirks.

My issue is, in my head file, i am outputting which causes issues for the headers which come after.

I have the following in head.php

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>
		<?php 
			if(isset($currentPageTitle)){
				echo $currentPageTitle;
			}else{
				echo 'Cricket Club';
			}; 
		?>
	</title>
	<?php 
			if(isset($currentPageMeta)){
				echo "<meta name='description' content='$currentPageMeta'>";
			}else{
				echo "<meta name='description' content='All the latest from CC'>";
			}; 
		?>
	
	<meta name="viewport" content="width=device-width, initial-scale=1.0">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

Is there a better way for me to achieve this?
