I have a pdf generated invoice witch i like to display inline in the browser:
link is for example: guest/view/invoice/vqhH8sujcOrpg0t2nF4WQExDLKXmYTNe
No extension.
the below code gets a failed to load PDF document when i change it to attachment it works but give a download while i like to display it inline.
$file = site_url('guest/view/generate_invoice_pdf/' . $invoice_url_key);
$filename = 'factuur.pdf';
header("Content-type: application/pdf");
header('Content-Disposition: inline; filename="' . $filename . '"');
header('Content-Transfer-Encoding: binary');
header('Accept-Ranges: bytes');
echo $file;
Sorry i though i did a thorough search but i din't solution is this:
Orginal from: Chrome has "Failed to load PDF document" error message on inline PDFs
I've been wrestling with this same issue. This is as close as I got to consistent results across browsers. I think that the reason you could be having problems is if some PDF's are too large for readfile() to handle correctly. Try this:
$fp = fopen($file, "r") ;
header("Cache-Control: maxage=1");
header("Pragma: public");
header("Content-type: application/pdf");
header("Content-Disposition: inline; filename=".$myFileName."");
header("Content-Description: PHP Generated Data");
header("Content-Transfer-Encoding: binary");
header('Content-Length:' . filesize($file));
ob_clean();
flush();
while (!feof($fp)) {
$buff = fread($fp, 1024);
print $buff;
}
exit;````

While writing a PHP-Script, im stuck at an issue i cant resolve.
The PHP-Script consist in letting a user download a .mp4 file. The download works without any issues but the file downloaded can not be played.
Heres the code:
<?php
$filepath = "/www/servermedia/technounion.mp4";
$filename = basename($filepath);
header("Content-type: video/mp4");
header("Content-Disposition: attachment; filename=.$filename");
readfile($filename);
exit;
?>
After the .mp4 file gets downloaded, it cannot be played.
It looks like this:
The error message means that Windows Media Player cannot play back the file because probably the player doesnt support the codec. I already tried with VLC but it does not work either.
EDIT:
Comparing both file sizes, the downloaded file is only a couple bytes large instead of the 3,73 MB of the file on the server
Your code is not well-formed, you miss to escape double-quotes by adding single-quotes as I done here, please test my answer.
<?php
$filepath = "/www/servermedia/technounion.mp4";
$filename = basename($filepath);
header('Content-Type: video/mp4');
header('Content-Disposition: attachment; filename="' . $filename . '"');
readfile($filename);
exit;
?>
But I suggest a more complex way:
<?php
$filepath = $_SERVER['DOCUMENT_ROOT'] . "/www/servermedia/technounion.mp4";
$filename = basename($filepath);
header('Content-Type: video/mp4');
header('Content-Disposition: attachment; filename="' . $filename . '"');
header('Content-Transfer-Encoding: binary');
header('Connection: Keep-Alive');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . sprintf("%u", filesize($filepath)));
set_time_limit(0);
$fh = fopen($filepath, "rb");
while (!feof($fh)) {
echo fgets($fh);
ob_flush();
flush();
}
fclose($fh);
exit;
?>
$_SERVER['DOCUMENT_ROOT'] is useful to get the full path from the server
set_time_limit(0) is useful to avoid any timeout during download
fgets() is useful for reading large files
ob_flush() and flush() assure that there is not other output in the buffer
I hope this helps.
Is the downloaded file the exact same filesize?
Does the content type exist in your webserver?
header("Content-Type: video/mp4"); Note capital 'T' for type.
This maybe worth testing with to see you can serve the file content inline:
http://www.phpmind.com/blog/2016/10/how-to-use-php-to-output-an-mp4-video/
I've made a page where you can go and write text in a "textarea" and then when you click download you download that file as a .txt file. I've done the same thing to some other extensions and that is working fine. But it won't work with .PDF, nothing I read works. Here is the snippet I use for the .PDF downloading:
<?php
if($fileFormat == ".pdf"){
$content = $_POST['text'];
$name = stripslashes($_POST['name']);
$nameAndExt = $name.".pdf";
print strip_tags($content);
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="'.$nameAndExt.'"');
header('Content-Transfer-Encoding: binary ');
}
?>
I'm grateful for any answear, thanks!
// hold the filename for use elsewhere so you don't have to append .pdf every time
$filename = "$id.pdf";
// create the file
$pdf->output( $filename );
// set up the headers
header("Content-Description: File Transfer");
header("Content-disposition: attachment; filename={$filename}");
header("Content-Type: application/pdf");
header("Content-Transfer-Encoding: binary");
header('Content-Length: ' . filesize($file));
// push the buffer to the client and exit
ob_clean();
flush();
// read the file and push to the output stream
readfile( $filename );
// remove the file from the filesystem
unlink( $filename );
exit();
I would recommend a class like TCPDF, see http://www.tcpdf.org/. I used it couple of times and it's quite nice (open source).
I download a file but it gives invalid file in return.
Here's my download_content.php
<?php
$filename = $_GET["filename"];
$buffer = file_get_contents($filename);
/* Force download dialog... */
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
/* Don't allow caching... */
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
/* Set data type, size and filename */
header("Content-Type: application/octet-stream");
header("Content-Transfer-Encoding: binary");
header("Content-Length: " . strlen($buffer));
header("Content-Disposition: attachment; filename=$filename");
/* Send our file... */
echo $buffer;
?>
download file link:
Download
$r['file'] contains the file name to be downloaded.
The complete path of the folder which contain the file is:
localhost/ja/gallery/downloads/poster/large/'.$r['file'].'
ja is the root folder in htdocs.
I don't know what the actual problem is, can anyone help me out please?
<?php
header( "Content-Type: application/vnd.ms-excel" );
header( "Content-disposition: attachment; filename=spreadsheet.xls" );
// print your data here. note the following:
// - cells/columns are separated by tabs ("\t")
// - rows are separated by newlines ("\n")
// for example:
echo 'First Name' . "\t" . 'Last Name' . "\t" . 'Phone' . "\n";
echo 'John' . "\t" . 'Doe' . "\t" . '555-5555' . "\n";
?>
As said in the other question, this way looks better:
$filename = $_GET["filename"];
// Validate the filename (You so don't want people to be able to download
// EVERYTHING from your site...)
// For example let's say that you hold all your files in a "download" directory
// in your website root, with an .htaccess to deny direct download of files.
// Then:
$filename = './download' . ($basename = basename($filename));
if (!file_exists($filename))
{
header('HTTP/1.0 404 Not Found');
die();
}
// A check of filemtime and IMS/304 management would be good here
// Google 'If-Modified-Since', 'If-None-Match', 'ETag' with 'PHP'
// Be sure to disable buffer management if needed
while (ob_get_level()) {
ob_end_clean();
}
Header('Content-Type: application/download');
Header("Content-Disposition: attachment; filename=\"{$basename}\"");
header('Content-Transfer-Encoding: binary'); // Not really needed
Header('Content-Length: ' . filesize($filename));
Header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
readfile($filename);
That said, what does "invalid file" mean? Bad length? Zero length? Bad file name? Wrong MIME type? Wrong file contents? The meaning may be clear to you with everything under your eyes, but from our end it's far from obvious.
UPDATE: apparently the file is not found, which means that the filename= parameter to the PHP script is wrong (refers a file that's not there). Modified the code above to allow a directory to contain all files, and downloading from there.
Your $filename variable contains whole path as below
header("Content-Disposition: attachment; filename=$filename");
Do like this
$newfilename = explode("/",$filename);
$newfilename = $newfilename[count($newfilename)-1];
$fsize = filesize($filename);
Then pass new variable into header
header("Content-Disposition: attachment; filename=".$newfilename);
header("Content-length: $fsize");
//newline added as below
ob_clean();
flush();
readfile($filename);
i though i found the answer here:
Serving .docx files through Php
But i am still getting the error that the file is corrupt when trying to download and open a docx server via php
Maybe you can see something wrong with my code. The .doc works fine it is the docx that fail.
$parts = pathinfo($doc);
$docFile = $userDocRoot.$doc;
if ( !file_exists($docFile) ){
throw new Exception("Can not find ".$parts ['basename']." on server");
}
if ( $parts['extension'] == 'docx' ){
header('Content-type: application/vnd.openxmlformats- officedocument.wordprocessingml.document');
header('Content-Disposition: attachment; filename="'.$parts['basename'].'"');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
ob_clean();
flush();
readfile($docFile);
}else{
header('Content-type: application/msword');
header('Content-Disposition: attachment; filename="'.$parts['basename'].'"');
readfile($docFile);
}
The solution for me was to add
$fsize = filesize($docFile);
header("Content-Length: ".$fsize);
Thanks for everyones help
There were a few extra spaces in your code which would cause it to fail.
Try using this code:
$parts = pathinfo($doc);
$docFile = $userDocRoot . $doc;
if(!file_exists($docFile)){
throw new Exception('Can not find ' . $parts['basename'] . ' on server');
}
if($parts['extension'] == 'docx') {
header('Content-type: application/vnd.openxmlformats-officedocument.wordprocessingml.document');
header('Content-Disposition: attachment; filename="' . $parts['basename'] . '"');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
ob_clean();
flush();
readfile($docFile);
} else {
header('Content-type: application/msword');
header('Content-Disposition: attachment; filename="' . $parts['basename'] . '"');
readfile($docFile);
}
If it still doesn't work, try commenting out the header and the readfile lines, then you will see if there are any errors.
Also, I suggest that you check the filenames against a whitelist, so that people can't download PHP files with passwords in them, etc.
I have just spent a while looking at why my DOCX files are being corrupted and stumbled across this... but I have also found the answer elsewhere...
$fsize = filesize($docFile);
header("Content-Length: ".$fsize);
This gave me the tools to look for... and the key is that filesize() needs the basename of the file to get an accurate file size!
Adapting my code:
header("Content-Length: ".filesize(basename($file)));
This now offers DOCX (I have set the Content-type to "application/vnd.openxmlformats-officedocument.wordprocessingml.document") as intended and I do not have to "repair" the document like others have reported... (I also found that repairing worked)
Here is a code that's working for me (after about 5 hours of messing around):
// headers to send your file
header('Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document');
header("Content-Length: " . filesize($original_file));
header('Content-Disposition: attachment; filename="' . $new_filename . '"');
ob_clean();
flush();
readfile($original_file);
exit;
I hope it helps :)
I had the same issue.
The reason was, that somewhere in my php-file two spaces were hidden.
Removing them fixed the issue.
Add "//" in front of the header and readfile-statements
Write echo "test"; after the readfile-statement.
Then look in the HTML source-code, if there are spaces in front of
the "test".
If I goto http://site.com/uploads/file.pdf I can retrieve a file.
However, if I have a script such as:
<?php
ini_set('display_errors',1);
error_reporting(E_ALL|E_STRICT);
//require global definitions
require_once("includes/globals.php");
//validate the user before continuing
isValidUser();
$subTitle = "Attachment";
$attachmentPath = "/var/www/html/DEVELOPMENT/serviceNow/selfService/uploads/";
if(isset($_GET['id']) and !empty($_GET['id'])){
//first lookup attachment meta information
$a = new Attachment();
$attachment = $a->get($_GET['id']);
//filename will be original file name with user name.n prepended
$fileName = $attachmentPath.$_SESSION['nameN'].'-'.$attachment->file_name;
//instantiate new attachmentDownload and query for attachment chunks
$a = new AttachmentDownload();
$chunks= $a->getRecords(array('sys_attachment'=>$_GET['id'], '__order_by'=>'position'));
$fh = fopen($fileName.'.gz','w');
// read and base64 encode file contents
foreach($chunks as $chunk){
fwrite($fh, base64_decode($chunk->data));
}
fclose($fh);
//open up filename for writing
$fh = fopen($fileName,'w');
//open up filename.gz for extraction
$zd = gzopen($fileName.'.gz', "r");
//iterate over file and write contents
while (!feof($zd)) {
fwrite($fh, gzread($zd, 60*57));
}
fclose($fh);
gzclose($zd);
unlink($fileName.'.gz');
$info = pathinfo($fileName);
header('Content-Description: File Transfer');
header('Content-Type: '.Mimetypes::get($info['extension']));
header('Content-Disposition: attachment; filename=' . basename($fileName));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($fileName));
ob_clean();
flush();
readfile($fileName);
exit();
}else{
header("location: ".$links['status']."?".urlencode("item=incident&action=view&status=-1&place=".$links['home']));
}
?>
This results in sending me the file, but when I open it I receive an error saying:
"File type plain text document (text/plain) is not supported"
First off, I'd start by checking the HTTP headers. You can do this in Firefox easily using the "Live HTTP headers" extension; not sure about equivalents in other browsers offhand. This will let you verify if the header is actually getting set to "application/pdf" and whether your other headers are getting set as well.
If none of the headers are getting set, you might be inadvertently sending output before the calls to header(). Is there any whitespace before the <?php tag?
Are you sure application/pdf is the header your browser is actually seeing?
You can check that out with various HTTP dev tools, for instance HTTP Client for the Mac or Firebug for Firefox.
I use this one and it works.
if(file_exists($file_serverfullpath))
{
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private", false);
//sending download file
header("Content-Type: application/octet-stream"); //application/octet-stream is more generic it works because in now days browsers are able to detect file anyway
header("Content-Disposition: attachment; filename=\"" . basename($file_serverfullpath) . "\""); //ok
header("Content-Transfer-Encoding: binary");
header("Content-Length: " . filesize($file_serverfullpath)); //ok
readfile($file_serverfullpath);
}
Try prepending "error_reporting(0);". I found this in the comments at http://php.net/readfile (where you took this example from).
Another thing that could be a problem is your file size. There have been issues reported in the past about PHP5 (we're talking 2005 here, so i hope this is fixed by now) having trouble reading files >2MB. If your file size exceeds this you may want to verify that it reads the whole file.
