Re: [PHP] Header problem - SOLVED
This has been solved today. Talawa had a similar problem and came up
with a solution to his problem, namely using session_write_close()
before creating the headers. That stunt also solved my problem :-)

Hi PHP people
I have a really strange and annoying problem. I've got a site, where
members can download music. User clicks index.php (in index.php
there's an iframe, that opens another file), if certain check are okay
then a popup window opens download.php, where a mp3 file is fetched
from the server and renamed in the header, then pushed to the enduser,
this works fine. But now I want to create zipfiles too but when a user
downloads a zipfile it's like the whole site is freezed until download
has completed. My guess is that this is some sort of header problem
(see headers below), due to three headers at the same time, cause the
class works as expected in the test page i've created. Inputs to
correct headers would be appriciated very much :-)
Mp3 headers:
$new_filename = attachment; filename=\{$artist} - {$title}.mp3\;
header('Content-Description: File Transfer');
header(Content-Type: application/octet-stream);
header(Content-Length: $size);
header(Content-Disposition: $new_filename);
header(Content-Transfer-Encoding: binary);
readfile($source_file);
Zip headers:
$zip = new zipfile();
$zip-add_dir(.);
$new_filename= {$artist} - {$title}.mp3;
if(mysql_num_rows($result)) {
$zip-add_file($file, $new_filename);
}
header(Pragma: public);
header(Expires: 0);
header(Cache-Control: must-revalidate, post-check=0, pre-check=0);
header(Cache-Control: private,false);
header(Content-type: application/zip);
#header(Content-Type: application/octet-stream);
header(Content-disposition: attachment; filename=\zipTest.zip\);
header('Content-Transfer-Encoding: binary');
ob_end_clean();
echo $zip-file();
Code example: http://lps.netlinq.dk/test010/test_zip.class.php
Headers (fetched with firefox add-on: live http headers)
This is headers from the site, where the problem occurs:
1. click on the link to a title (Maxwell in this case)

It's still not the ultimate solution as we wanted the zipfile to be created on the fly in memory in order not to have to delete files afterwards and to be sure that only allowed users can fetch the files (of course you can always put the zipfiles outside webscope, but still...) -- Kind regards Kim Emax -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Header problem
Andrea Giammarchi wrote on 2009-10-03 13:40:
Do you want users download the file or the zip?
They can choose between the two.
do you send other headers before the download?
Header must come first (before you output anything) or you get a parse
error, so I'm not sure what you mean here? You can see the source of the
class at the testpage I linked to.
It's quite a common error to set a default header in PHP at the
beginning of whatever application, while header should be used as last
exit point and never in the middle, or at the beginning, of a response.
I'm not sure what you mean by this? My download.php first checks for the
relevant data is there (track_id/version_id, a session with member_id),
then if the download is allowed (by access or if it has already been
downloaded) then it fetches the relevant files, zip these to the disk
and first then... creates the zip header and afterwards uses a readfile
on the zipfile just created.
Moreover, if you use readfile and then zip what do you expect,
multiple downloads in one? This is not how HTTP work ... so please show
more php, or explain better what you would like to do.
What do you need to see besides the testpage?
If I have 4 mp3 files of 5mb each, these will be zipped into one 20mb
file, and that is of course only one download. That's the wish from the
siteowner: easier download of several mixes of the same artist/track
I hope this makes the problem more clear to you :-)
I've debugged some more into the problem, this is a header of a zip
download where the site works as expected:

I call the file like this: index.php?get_zip=test_output.zip
index.php does this:
$new_zipfile .= $_SESSION['download_title']..zip;
/*

header(Pragma: no-cache);

header('Accept-Ranges: bytes');

header(Content-Length: .filesize($archiveName));
header(Content-Disposition: attachment; filename=\$new_zipfile\);
header(Content-Transfer-Encoding: binary);
readfile($archiveName);
exit;
The outcommented headers was put in because I discovered that the
download then was cached after giving the file a strange name, that name
never occured in the download :-/ I've ended up by making a workaround
by adding nocache=.microtime(). to the get_zip link but then the site
freezes againg during the download, arrrghh...
And headers from the original zip solution in download.php, headers are
set in function.inc, this is the output from Live HTTP headers:

difference to the returned zip headers in index.php is pragma,

RE: [PHP] Header problem
Afaik, the content length header is not necessary, but it will cause problems if it's set and it's wrong. correct, missed Content-Length means the classic download with useless progress bar and undefined estimation time, problematic for preloader as well in case of images, swf, generic data, etc. Content_length should be always present and it should be correct, but obviously if there are print or echo or other outputs non file related, Content-Length can simply mess up the response. _ Windows Live: Friends get your Flickr, Yelp, and Digg updates when they e-mail you. http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/social-network-basics.aspx?ocid=PID23461::T:WLMTAGL:ON:WL:en-xm:SI_SB_3:092010

the headers have been sent and the file have been pushed. I do an update
of the database to tell the system that the files in the zipfile has
been downloaded.

anything except the expected output with expected headers, that's why I
have said headers are fundamental for a response, we cannot play with

header('Accept-Ranges: bytes');
header(Content-Type: application/zip);
header(Content-Length: $size);
header(Content-disposition: attachment;

header(Content-Transfer-Encoding: binary);
readfile($filename);
// we need to reload top5 to have a current view
unset($_SESSION['top5']);
$_SESSION['reload_top5'] = 1;
// NOTE second param shall be an array, not a variable when
downloading zip files
download_completed($member_id, $downloaded_version_ids);
Wouldn't you say this is okay?
As summary, once you have created and tried a dedicated page without a
single white space or print before, during, or after the dedicated
download stuff, I'll try to understand where is the error.
Otherwise it could be everything, and I am against magic behaviors ...
you need to download? Well, create a file which aims id to download and

RE: [PHP] Header problem
Unless I am missing something, your page has too many if and it always ends up
with print something ... but there is no exit after the download, so the zip
will have extra output included without a reason ... which is an error, imho,
dunno how else explain if you can't see your print links at the end of the
page ...

I try to better explain ...
HTTP works like this: you ask something, you receive something, html and
texts are just one option.
Got it so far
Your example page mess up html, zip, everything, because when you
download a file you still have the rest of the page sent in the output.
Nops, not really.
index.php:
print stuff
do stuff
open download.php in a _new_ window.
print more stuff
page end
this should be possible, right? Two different headers for two different
pages.
A download should have ONLY file related info/headers and nothing else

[PHP] Header problem
Hi PHP people
I have a really strange and annoying problem. I've got a site, where
members can download music. User clicks index.php (in index.php
there's an iframe, that opens another file), if certain check are okay
then a popup window opens download.php, where a mp3 file is fetched
from the server and renamed in the header, then pushed to the enduser,
this works fine. But now I want to create zipfiles too but when a user
downloads a zipfile it's like the whole site is freezed until download
has completed. My guess is that this is some sort of header problem
(see headers below), due to three headers at the same time, cause the
class works as expected in the test page i've created. Inputs to
correct headers would be appriciated very much :-)
Mp3 headers:
$new_filename = attachment; filename=\{$artist} - {$title}.mp3\;
header('Content-Description: File Transfer');
header(Content-Type: application/octet-stream);
header(Content-Length: $size);
header(Content-Disposition: $new_filename);
header(Content-Transfer-Encoding: binary);
readfile($source_file);
Zip headers:
$zip = new zipfile();
$zip-add_dir(.);
$new_filename= {$artist} - {$title}.mp3;
if(mysql_num_rows($result)) {
$zip-add_file($file, $new_filename);
}
header(Pragma: public);
header(Expires: 0);
header(Cache-Control: must-revalidate, post-check=0, pre-check=0);
header(Cache-Control: private,false);
header(Content-type: application/zip);
#header(Content-Type: application/octet-stream);
header(Content-disposition: attachment; filename=\zipTest.zip\);
header('Content-Transfer-Encoding: binary');
ob_end_clean();
echo $zip-file();
Code example: http://lps.netlinq.dk/test010/test_zip.class.php
Headers (fetched with firefox add-on: live http headers)
This is headers from the site, where the problem occurs:
1. click on the link to a title (Maxwell in this case)

RE: [PHP] Header problem
Do you want users download the file or the zip?
do you send other headers before the download?
It's
quite a common error to set a default header in PHP at the beginning of
whatever application, while header should be used as last exit point
and never in the middle, or at the beginning, of a response.
Moreover,
if you use readfile and then zip what do you expect, multiple downloads
in one? This is not how HTTP work ... so please show more php, or
explain better what you would like to do.

Re: [PHP] header problem
Hi Blueman. As soon as ANYTHING has been drawn to the browser, you
cannot use a header command. So you need to work through all of your
code, and ensure that all of your logic that could result in a header
call is run BEFORE you send any html code. Is going to be tricky if
mixing html and php calls.

Several:
* Javascript - not always available on your target system, or
blocked by script blocking plugins
* Meta refresh tags - should be honored by the user agent, but may
not always be.
The problem you have is not that you need to work around this 'problem'
in PHP, but you need to fix your broken code. This problem often comes
up on the list, and is usually because of extra whitespace in include
files, or errors being output to the browser which force the headers to
be sent.

Usually, when I have to redirect the user AFTER headers has been sent (like
showing an error message), I write this:
SCRIPTlocation=page_to_send.html/SCRIPT
But this will redirect the user at once. If you want the user to read the
page, you should do something in Javascript with setTimeout(func,timeout)
function.

Hi Blueman. As soon as ANYTHING has been drawn to the browser, you cannot
use a header command. So you need to work through all of your code, and
ensure that all of your logic that could result in a header call is run
BEFORE you send any html code. Is going to be tricky if mixing html and
php calls.

Don't use a timer to redirect if you want the user to read a message, as
this assumes that the visitor is a good reader. This is forgetting all
of those visitors with reading difficulties (i.e. Dyslexia), those users
who have attention problems who can't focus on text for long periods
(i.e. ADHD) and any users who rely on things such as screen readers
(which are slower than reading text yourself (if you're an average
reader!) ) or a Braille browser.
In cases such as these, it's best to let the visitor move at their own
pace and not redirect until they want to.
Thanks,
Ash

It's possible that on your localhost you have output_buffering set on either
in php.ini or in a .htaccess, which would avoid the displayed error about
headers. If it's switched on locally and off for your host server then
you'll get the problem you reported. Check that this is off locally (use
phpinfo) so that you can be sure your code is working properly before you
upload.
Alternatively if you want to be able to do a redirect after you've already
started your output (this is sometimes done for error handling) you could
use ob_start() to start output buffering, ob_end_clean() to clear the output
buffer and start again, and ob_flush() to send the output buffer. If you
want to continue using output buffering after an ob_end_clean() you'll have
to do an ob_start() again.
Cheers

[PHP] header problem for mobile browser
Hi, I want to make a php file for download a jad file. I am using following script to let browser understand that jad file is coming and download it. But I have very interesting problem. If user open browser and write correct addres following script let the download file. But if the user open browser and write wrong addres and get some error. After write correct address, still getting same error. I think following script can not reset the previos header and browser still using previous header and bring back an error. What should I do, for this problem, any idea $SRC_FILE = $file; $download_size = filesize($SRC_FILE); $filename = basename($SRC_FILE); header(Content-Type: text/vnd.sun.j2me.app-descriptor); header(Content-Disposition: attachment; filename=$filename); header(Accept-Ranges: bytes); header(Content-Length: $download_size); @readfile($SRC_FILE); -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Not sure If I have understood your question correctly but surely it
would be easier for you to just add the following lines to your
.htaccess file and give a direct download link instead of trying to
deliver through a php script.
addtype application/java-archive jar
addtype text/vnd.sun.j2me.app-descriptor jad
if you do deliver through a php script, the phone will follow up with a
request for the jar file when it has recieved the jad file, your script
needs to be able to handle that as well.
But I have very interesting problem. If user open browser and write correct
addres following script let the download file.

you cannot reset headers once they have been sent. The headers you use
seem ok but i would add a no-cache header as well.
header('Pragma: no-cache');
What should I do, for this problem, any idea
$SRC_FILE = $file;
$download_size = filesize($SRC_FILE);
$filename = basename($SRC_FILE);
header(Content-Type: text/vnd.sun.j2me.app-descriptor);
header(Content-Disposition: attachment; filename=$filename);
header(Accept-Ranges: bytes);

Re: [PHP] header() problem!!!!
I have not had any problems on IE 6 with this. The code I am using on numerous
scripts looks like this:
header(Content-Disposition: attachment; filename=$filename);
header(Content-Type: application/octet-stream);
fpassthru($filehandle);
fclose($filehandle);
Maybe the the combination of using the echo and the attachment field? The echo
might not treat it as a real file? Just a thought.

[PHP] header problem
i'm setting up a messages option on my site, i was looking in the documentation and read that if headers are not included in an e-mail, the message is sent to the junk folder, i don't use hotmail (so i would not know), however i am adding headers: using // The headers $myHeaders = From: \.Autoresponse.\ .$myAddress.\r\n; $myHeaders .= To: \.$myName.\ .$myAddress.\r\n; $myHeaders .= Reply-To: \.$myName.\ .$myAddress.\r\n; $myHeaders .= MIME-Version: 1.0\r\n; $myHeaders .= Content-Type: text/html; charset=iso-8859-1\r\n; $myHeaders .= X-Priority: 1\r\n; $myHeaders .= X-MSMail-Priority: High\r\n; $myHeaders .= X-Mailer: Just My Server; // send the e-mail mail($myAddress, $mySubject, $myMessage, $myHeaders); ## when testing the file i get the response e-mail, however at the top of the e-mail i get the following: Content-Type: text/html; charset=iso-8859-1 X-Priority: 1 X-MSMail-Priority: High X-Mailer: Just My Server this must mean that i have written the headers wrong, can someone point me in the right direction thanks | Mike | -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] header() problem??
I am trying to replace a perl script with the following PHP code. The perl code
acted like a redirector, sending you to a different script depending on the
value of the submit button. The following replacement code written in PHP works
quite well until the postString exceeds some unknown size (This number must be
known by someone because it is always chopping it at the same place). Why will
this not work and how can I fix it?? It seems to break when sending script has
more than 30 lines of form input, works fine otherwise.
?
while(list($key, $val) = each($HTTP_POST_VARS)) {
$key = stripslashes($key);
$val = stripslashes($val);
$key = urlencode($key);
$val = urlencode($val);
$postString .= $key=$val;
}
if ($defloc){
$gotoscript = $defloc;
}
$location = '/scriptdirectory/';
$go = http://www.site.com.$location.$gotoscript.?.$postString;
header(Location: $go);

I use this headers Header(Content-Type: application/download\n); Header(Content-Disposition: attachment;filename=\name_of_file\); Header(Content-Transfer-Encoding: binary); On Windows it works good, but on Mac it doesn't accept name_of_file and try save this file with name of script. What is wrong ? Do you have any idea ?? If I used: Header(Content-Disposition: filename=\jmeno_souboru\); then this script doesn't work also on Windows with Mozilla. Is there any error in MSIE on Mac, isn't it ?

Re: [PHP] Header problem
It seems to be bug in IE/Netscape/Other www browser on Mac, that's all. Header wasn't correct interpreted. I had similar problem with NETSCAPE 6 on Windows. I hope they will correct it shortly.

[PHP] Header Problem...
Hi all,
could any one tell me that how do I go to a specific URL using php
command.At the same time, I would like to pass the variable to the page.
I used header to do it but failed, with the error message:-
Warning: Cannot add header information - headers already sent by (output
started at /usr/local/apache/htdocs/traName_use.php:2) in
/usr/local/apache/htdocs/traName_use.php on line 3
Warning: Cannot add header information - headers already sent by (output
started at /usr/local/apache/htdocs/traName_use.php:2) in
/usr/local/apache/htdocs/traName_use.php on line 4
Warning: Cannot add header information - headers already sent by (output
started at /usr/local/apache/htdocs/traName_use.php:2) in
/usr/local/apache/htdocs/traName_use.php on line 26
And our code is as below:-
?php
header("Pragma : no-cache ");
header("Cache-Control :no-cache,must-revalidate");
$db=mysql_connect("localhost","root","123456");
mysql_select_db("test",$db);
$query="select trade_name_c
from confirm_member_info
where trade_name_c = '$tradeName'";
$result=mysql_query($query,$db);
$row=mysql_fetch_row($result);
if($row[0]==$tradeName)
{
//echo "Sorry, the Trade Name b$tradeName/b has been usedBr";
//echo "Please Choose other Trade NameBR";
//echo "Click a href='mysignup_1.php'here/a to back.";
header("Location: http://192.168.0.1/mysignup_1.php");
}
else
{
//echo "Your Trade Name and password has been accepttedbr";
//echo "Click to proceed.";
//input type='hidden' name='introducer' value='$introducer'
header("Location: http://www.hotmail.com");
}
?
input type="hidden" name="tradeName" value="?$tradeName?"
input type="hidden" name="password" value="?$password?"
input type="hidden" name="MotherName" value="?$MotherName?"
I tried to use hidden input type to pass the value, but can it work without
form and submit button??
I would appreaciate if you could give me suggestions and advice.
thanks

Re: [PHP] Header Problem...
There may not be any headers before you use the 'header' statement.
The header("Location:...") should be the first output you send. You
might want to consider moving the two 'anti-cache' headers after the
header("Location;...") statement.

Re: [PHP] Header Problem
Hello,
Yes this should work, but if like me, you still have no redirection and
you are working with IE 4.0, put exit; after header.
$URL="domain.com";
header ("Location: Http://www.$URL/members/index.php");
exit;
I have not seen this anywhere, but putting exit; after a redirection
was the only way to get my redirection with header to work.

$URL changes so I can`t write it directly into the header line, anyone?

Re: [PHP] Header Problem
What happens when it doesn't work, any error messages?
Try:
header ("Location: http://www." . $URL . "/members/index.php");
or
$loc = "Location: http://www." . $URL . "/members/index.php";
header ($loc);
The first suggestion should work.
