PHP - Problem With Downlod Script - Maybe Wrong Headers?
Hi all,
I wrote a download script for some protected files a little while back. And on the whole, its works pretty well but occasionally, zip files will not completely download and will end up corrupted. It happens more with bigger files but that i'm guessing is due to the fact it takes longer to download them? I've searched intensively on Google for the past few days and implemented a few new ideas, which hasn't made a difference. Its annoying, in the fact you can try the same file a few times over and it'll download 8 out of 10 times no problem. I even added in the apachesentenv after a recommendation, as the rest of my site is gzip php'd. But that hasn't worked either. Part of the code as follows: apache_setenv('no-gzip', '1'); // if file exists and user access granted: // define the path to your download folder plus assign the file name $path .= $filename; // check that file exists and is readable if (file_exists($path) && is_readable($path)) { // get the file size and send the http headers $size = filesize($path); // required for IE, otherwise Content-disposition is ignored if(ini_get('zlib.output_compression')) ini_set('zlib.output_compression', 'Off'); //content type switch(strtolower(substr(strrchr($filename,'.'),1))) { case "pdf": $mime="application/pdf"; break; case "mp3": $mime="audio/x-mp3"; break; case "zip": $mime="application/zip"; break; case "rar": $mime="application/zip"; break; case "tar": $mime="application/zip"; break; case "sit": $mime="application/zip"; break; case "doc": $mime="application/msword"; break; case "xls": $mime="application/vnd.ms-excel"; break; case "ppt": $mime="application/vnd.ms-powerpoint"; break; case "gif": $mime="image/gif"; break; case "png": $mime="image/png"; break; case "jpeg":$mime="image/jpg"; break; case "jpg": $mime="image/jpg"; break; default: $mime="application/force-download"; } header("Cache-Control: public"); header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Content-Description: File Transfer"); header("Content-Type: " .$mime); header("Content-Disposition: attachment; filename=\"{$filename}\""); header('Content-Transfer-Encoding: binary'); header('Content-Length: ' . filesize($path)); readfile("$path"); if($logging == 1){ $status = "Granted"; include('logit.php'); } exit; } Live http Headers in Firefox displays the following upon clicking a download: http://www.website.com/filedownload.php?file=12 GET /filedownload.php?file=12 HTTP/1.1 Host: www.website.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12 ( .NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-gb,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://www.website.com/downloads.php Cookie: __utma=100661891.2064943237.1286446219.1290502952.1290505322.70; __utmz=100661891.1290502952.69.8.utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=lighthouse%20cjpro; __utmc=100661891; __utmb=100661891.43.10.1290505322; PHPSESSID=8aadcc17930b9e146f103f180f30f470 HTTP/1.1 200 OK Date: Tue, 23 Nov 2010 11:22:13 GMT Server: Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 PHP/5.2.12 X-Powered-By: PHP/5.2.12 Expires: 0 Cache-Control: must-revalidate, post-check=0, pre-check=0 Pragma: public Content-Description: File Transfer Content-Disposition: attachment; filename="Version_5_Software.zip" Content-Transfer-Encoding: binary Content-Length: 62654423 Keep-Alive: timeout=2, max=100 Connection: Keep-Alive Content-Type: application/zip ---------------------------------------------------------- Are my headers wrong? or in the incorrect order?

I'm trying to start a session in a simple php file.
Here's *all* the code:
Here's the URL: I'm adding a login page to my website. When I go to the login page, and try to login, I keep getting the error "Warning: Cannot modify header information - headers already sent by (output started at C:\Users\me\Desktop\xampp\htdocs\site\login.php:7) in C:\Users\me\Desktop\xampp\htdocs\site\login.php on line 38" and I don't know why.

but I get headers allready sent. I was earlier told to learn and code or make my apps different, but I'm totaly stuck cause I need to make a page with those stats. Not sure how I can make all my code be processed first then put into the html area. Is a function the way to go here ?
Thanks for reading and hope someone can enlighten me
I have a strange problem with my headers in my mail function.
This is how it looks like in my code:
$to = 'someone@email.com'; $subject = 'Question from website'; $headers = 'MIME-Version: 1.0' . "\r\n"; $headers .= 'Content-type: text/html;charset=UTF-8' . "\r\n"; $headers .= 'From: ' . $email . "\r\n";When i send this i got the following message in my mailbox:
Content-type: text/html;charset=UTF-8

I have allready found that the space between "Content-type" and "From" is not normal that indicates that a rule between MIME and Content-type is also present. But in my code there isn't any rule... How can this be possible?

I am pulling variables from a text file and looping them through a function in order to get a result, problem is, that something is happening that is not allowing the results to pass through correctly. Weird thing is, that if there is only one variable present, the script works, if more than one variable is in the list, then that's where the problem comes in. The script only returns the correct result with the last variable in the list, all other variables seem to no be passing correctly. Here is the process: grab first line of text file use that variable to request data from an ssl site using fsock returns a result based on returned data from the post query loops back around to start over with next variable in list. I have tried everything that i could think of. I basically want the script to reset completely as if only one variable were submitted. I am suspecting that it has something to do with the foreach() function. Does it have anything to do with the session since its ssl? Like I said when only one variable is present in the text file, it works accordingly. When more than one variable, it only works correctly with the last variable. The other variables return the incorrect result. at the end of the file, i even manually unset every variable in the script to make sure that i starts with all variables undefined just in case and still... no dice. code that i am using can be viewed at http://fontestad.net/personal/jf/pt/t.phps thank you. I am querying... $sql = "SELECT `messages_inbox`.`message_id`, `users`.`firstname`, `users`.`lastname`, `users`.`username` AS `from`, '${user_info['username']}' AS `to`, `subject`, LENGTH(`files`) AS `len`, 'inbox' AS `box`, DATE_FORMAT(`messages_inbox`.`time` ,'%T %D-%M-%Y') AS `time` "; $sql .= "FROM `messages_inbox` INNER JOIN `users` ON `messages_inbox`.`from_id` = `users`.`id` WHERE `to_id` = ${user_info['uid']} AND `messages_inbox`.`deleted` = 0 ORDER BY `messages_inbox`.`message_id` DESC"; and I am trying to output $displayName = ucwords("${message['firstname']} ${message['lastname']}"); by using $messages = pm_fetch_all($_GET['box']); I know my fetch works but for some reason firstname and lastname are only returning the logged in users first name and last name, not the person who sent the message.

The section of code that is causing this problem is above any HTML tags, at the very beginning of the file. <?php include('functions.php'); ?> <link href="style.css" rel="stylesheet" type="TEXT/CSS"> <img src="logo.png" border="0"> <div id="maincontent"> As you can see, the functions that cause this error are at the VERY beginning of my file.

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 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! Dave 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:" . $from; header('Location: index.php?done'); ?> And I'm getting: Code: [Select] Warning: Cannot modify header information - headers already sent by (output started at /home/site/public_html/config.php:10) in /home/site/public_html/send.php on line 13 This worked before. Many thanks I am trying to do a page redirect using the header() function.
I am aware that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP.
and also that reading code with include, or require, functions, or another file access function, can create spaces or empty lines that are output before header() is called. thus causing a redirect failure.
I have therefore used this output control function (ob_start(); ob_implicit_flush() right at the top of my page.
I am then creating the redirect like this as part of my login() function:
if($user_role == ADMIN_LEVEL || $user_role == EDITOR_LEVEL)
{
if (!headers_sent($filename, $linenum))
{
return header("Location:http://mysite.com/dashboard.php");
exit;
}
else
{
echo "Headers already sent in $filename on line $linenum\n" .
"Cannot redirect\n";
exit;
}
}
Unfortunately I am still getting this error:
Headers already sent in /home/steveoje/public_html/login.php on line 1 Cannot redirectAnd this is what I have at the top of the login.php page:
<?php ob_start();
ob_implicit_flush();
require_once 'includes/config.php';
if(isset($_POST['submit']))
{
login($_POST['username'], $_POST['password']);
}
require_once "includes/header.inc.php" ?>
//other html content
So why would the redirect fail in this instance?
Thanks.

I want to get the response headers using ob_get_contents ?
For example using file_get_contents, it is easy by accessing the variable $http_response_header like that :
<?php $content = file_get_contents($url); print_r($http_response_header); ?>But how to do that using ob_get_contents without a file_get_contents ? something like for example : <?php ob_start(); include($path_to_script_here); $string = ob_get_contents(); // Access the headers here ob_end_clean(); ?>Thank you Edited by Dareros, 07 October 2014 - 06:20 PM. |
