Tcpdf generates pdf as filename.pdf.html in safari Mac and it loads as html file not as pdf file. what parameters should I set to download it as pdf in safari?
It is working fine in all other browsers.
Here is my function:
$pdf_content = $libTcpdf->downloadReceipt((string) $view->render());
$pdf_content->Output("Receipt.pdf", 'D');
html page is stored in a view.
In tcpdf.php(tcpdf library)
case 'D': {
// download PDF as file
if (ob_get_contents()) {
$this->Error('Some data has already been output, can\'t send PDF file');
}
header('Content-Description: File Transfer');
if (headers_sent()) {
$this->Error('Some data has already been output to browser, can\'t send PDF file');
}
header('Cache-Control: private, must-revalidate, post-check=0, pre-check=0, max-age=1');
//header('Cache-Control: public, must-revalidate, max-age=0'); // HTTP/1.1
header('Pragma: public');
header('Expires: Sat, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT');
// force download dialog
if (strpos(php_sapi_name(), 'cgi') === false) {
header('Content-Type: application/force-download');
header('Content-Type: application/octet-stream', false);
header('Content-Type: application/download', false);
header('Content-Type: application/pdf', false);
} else {
header('Content-Type: application/pdf');
}
// use the Content-Disposition header to supply a recommended filename
header('Content-Disposition: attachment; filename="'.basename($name).'"');
header('Content-Transfer-Encoding: binary');
$this->sendOutputData($this->getBuffer(), $this->bufferlen);
break;
}
Content-type is set to application/pdf.

I have a simple web page which pulls some data from DB and displays it in a html table and stores the data in some session variables.
I have a button "Export to csv" which calls a page which exports the results to a csv file.
The code for ExportToCsv file is:
<?php
session_start();
include "conn/sqlserverConn.php";
function download_send_headers($filename) {
// disable caching
$now = gmdate("D, d M Y H:i:s");
header("Expires: Tue, 03 Jul 2001 06:00:00 GMT");
header("Cache-Control: max-age=0, no-cache, must-revalidate, proxy-revalidate");
header("Last-Modified: {$now} GMT");
// force download
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
// disposition / encoding on response body
header("Content-Disposition: attachment;filename={$filename}");
header("Content-Transfer-Encoding: binary");
}
$data = $_SESSION['data'];
$rows = $_SESSION['row'];
$header = $_SESSION['header'];
download_send_headers("data_export_" . date("Y-m-d") . ".csv");
$file = fopen("php://output", 'w');
fputcsv($file,$header);
for($i=0; $i<$rows; ++$i)
{
$valuesArray=array();
foreach($data[$i] as $name => $value)
{
$valuesArray[]=$value;
}
fputcsv($file,$valuesArray);
}
fclose($file);
die();
?>
My code is working flawlessly in firefox but it is not working in chrome or IE. On chrome and IE it is showing error 404 (Object not found!). Please tell me what is the problem ?
As outlined in the blog article at: http://www.exchangecore.com/blog/php-output-array-csv-headers/, I tested the following and it worked in IE8-11, and in chrome version 34. I presume it will work in other browsers fine as well.
Headers to use:
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: text/csv');
header('Content-Disposition: attachment;filename=' . $fileName);
Can you tell me what is wrong with my headers? My download is not effective. I use PHPWord library but I don't think it's a problem
<?php
require_once 'PHPWord.php';
$PHPWord = new PHPWord();
$section = $PHPWord->createSection();
$wordText = utf8_encode($_REQUEST['TEXT']);
$section->addText($wordText);
$objWriter = PHPWord_IOFactory::createWriter($PHPWord, 'Word2007');
//$objWriter->save('helloWorld.docx');
$path = 'tmp/kikou2.docx';
$objWriter->save($path);
//download code
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' .$path);
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Content-Length: ' . filesize($objWriter));
readfile($objWriter);
unlink($objWriter); // deletes the temporary file
exit;
?>
Thanks
Recommends headers for an OfficeOpenXML .docx file

paying particular attention to the Content-Type heading
header('Content-Description: File Transfer');
header('Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document');

Add two headers:
header("Content-Type: application/force-download");
header("Content-Type: application/download");
$document->save($url.'temp/Form Letters1.docx');
$path = $url.'temp/Form Letters1.docx';
header('Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document');
header('Content-Disposition: attachment;filename="Form Letters1.docx"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($path));
ob_clean();
flush();
readfile($path);
I'm making a simple download script, where my users can download their own images etc.
But I'm having some weird problem.
When I've downloaded the file, it's having the contents from my index.php file no matter what filetype I've downloaded.. My code is like so:
$fullPath = $r['snptFilepath'] . $r['snptFilename'];
if (file_exists($fullPath)) {
#echo $fullPath;
// setting headers
header('Content-Description: File Transfer');
header('Cache-Control: public'); # needed for IE
header('Content-Type: '.$r['snptFiletype'].'');
header('Content-Disposition: attachment; filename='. $filename . '.' . $r['snptExtension']);
header('Content-Length: '.$r['snptSize'].'');
readfile($fullPath)or die('error!');
} else {
die('File does not exist');
}
$r is the result from my database, where I've stored size, type, path etc. when the file is uploaded.
UPDATE
When I'm uploading and downloading *.pdf files it's working with success. But when I'm trying to download *.zip and text/rtf, text/plain it's acting weird.
By weird I mean: It downloads the full index.php file, with the downloaded file contents inside of it.
ANSWER
I copied this from http://php.net/manual/en/function.readfile.php and it's working now. It seems that : ob_clean(); did the trick! Thanks for the help everyone.
#setting headers
header('Content-Description: File Transfer');
header('Content-Type: '.$type);
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
exit;
Try this function , or implement these headers to your code
function force_download($filename) {
$filedata = #file_get_contents($filename);
// SUCCESS
if ($filedata)
{
// GET A NAME FOR THE FILE
$basename = basename($filename);
// THESE HEADERS ARE USED ON ALL BROWSERS
header("Content-Type: application-x/force-download");
header("Content-Disposition: attachment; filename=$basename");
header("Content-length: " . (string)(strlen($filedata)));
header("Expires: ".gmdate("D, d M Y H:i:s", mktime(date("H")+2, date("i"), date("s"), date("m"), date("d"), date("Y")))." GMT");
header("Last-Modified: ".gmdate("D, d M Y H:i:s")." GMT");
// THIS HEADER MUST BE OMITTED FOR IE 6+
if (FALSE === strpos($_SERVER["HTTP_USER_AGENT"], 'MSIE '))
{
header("Cache-Control: no-cache, must-revalidate");
}
// THIS IS THE LAST HEADER
header("Pragma: no-cache");
// FLUSH THE HEADERS TO THE BROWSER
flush();
// CAPTURE THE FILE IN THE OUTPUT BUFFERS - WILL BE FLUSHED AT SCRIPT END
ob_start();
echo $filedata;
}
// FAILURE
else
{
die("ERROR: UNABLE TO OPEN $filename");
}
}
I copied this from http://php.net/manual/en/function.readfile.php and it works now. ob_clean(); did the trick..

I have built a simple file manager where users can download any type of file such as pdf, word or gif files. I want all of them to download file rather than view it in browsers. The uploaded filenames are stored in database.
<?php
// We'll be outputting a PDF
header('Content-type: application/pdf');
// It will be called downloaded.pdf
header('Content-Disposition: attachment; filename="downloaded.pdf"');
// The PDF source is in original.pdf
readfile('original.pdf');
?>
http://php.net/manual/en/function.header.php
You can use the "Content-Disposition" header for that:
header("Content-Disposition: attachment");
The PHP manual provides an excellent example for that.
Normally setting the Content-Disposition to attachment before sending a file force a download by the browser.
You either need to configure your web server to provide this header for the files or send them yourself via PHP, sending a specific header before like :
header('Content-Disposition: attachment; filename=your_file_name.pdf');
Beware that the first solution is better as you won't risk your downloads being cut because the script running time is too long (you could also alter it).
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT\n");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Content-type: application/pdf;\n");
$len = filesize($filename);
header("Content-Length: $len;\n");
header("Content-Disposition: attachment; filename=\"downfile.pdf\";\n\n");
echo readfile($filename)
source code taken from the TCPDF library
// download PDF as file
if (ob_get_contents()) {
$this->Error('Some data has already been output, can\'t send PDF file');
}
header('Content-Description: File Transfer');
if (headers_sent()) {
$this->Error('Some data has already been output to browser, can\'t send PDF file');
}
header('Cache-Control: public, must-revalidate, max-age=0'); // HTTP/1.1
header('Pragma: public');
header('Expires: Sat, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT');
// force download dialog
if (strpos(php_sapi_name(), 'cgi') === false) {
header('Content-Type: application/force-download');
header('Content-Type: application/octet-stream', false);
header('Content-Type: application/download', false);
header('Content-Type: application/pdf', false);
} else {
header('Content-Type: application/pdf');
}
// use the Content-Disposition header to supply a recommended filename
header('Content-Disposition: attachment; filename="'.basename($name).'";');
header('Content-Transfer-Encoding: binary');
$this->sendOutputData($this->getBuffer(), $this->bufferlen);
break;
anyways the most important part is
header('Content-Disposition: attachment; filename="'.basename($name).'";');
and notice that final ; inside the string, without it, it won't work
I am trying to generate an excel file with php. This works fine in Firefox but with IE I am only getting an empty file. This is what I am doing basically:
header('Content-type: application/ms-excel');
header('Content-Disposition: inline; attachment; filename='.$filename);
echo $data;
I have tried various header settings but no success. I have also tried to output the content as a text file, same result here. No content in IE.
Any ideas?
header("Cache-Control: no-stor,no-cache,must-revalidate");
header("Cache-Control: post-check=0,pre-check=0", false);
header("Cache-control: private");
header("Content-Type: application/octet-stream");
header('Content-Disposition: inline; attachment; filename='.$filename);
header("Content-Transfer-Encoding: binary");
header("Pragma: no-cache");
header("Expires: 0");
--
header('Pragma: public');
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
header('Last-Modified: '.gmdate('D, d M Y H:i:s') . ' GMT');
header('Cache-Control: no-store, no-cache, must-revalidate');
header('Cache-Control: pre-check=0, post-check=0, max-age=0');
header ("Pragma: no-cache");
header("Expires: 0");
header('Content-Transfer-Encoding: none');
header('Content-Type: application/vnd.ms-excel;');
header("Content-type: application/x-msexcel");
header('Content-Disposition: inline; attachment; filename='.$filename);
Just two Options, also tried some other combinations.
Thanks,
Roland
Had the same problem: IE times out after some short time if it doesn't get a response, even if the TCP connection is still open. What helped me was this: disable output buffering, send headers and flush them out. Send data when you have them. This was enough to keep the connection open.
Something like this:
// reset all output buffering
while (ob_get_level() > 0) {
ob_end_clean();
}
header('Content-type: application/ms-excel');
header('Content-Disposition: inline; attachment; filename='.$filename);
// we can't send any more headers after this
flush();
$excel = new PhpExcel();
$excel->setActiveSheetIndex(0);
$sheet = $excel->getActiveSheet();
// in this example, $data was an array in the format row => value
// data structure is not relevant to issue
foreach ($data as $key => $value) {
// add data to sheet here
$sheet->SetCellValue('A' . $key, $value);
// etc...
}
$writer = new PHPExcel_Writer($excel);
// push to browser
$writer->save('php://output');
Set your header to header("Content-Type: application/octet-stream"); to force a download.
or another version of your header is adding vnd so application/vnd.ms-excel but if you send this header then you should also send your current header along side it as some browsers vary.
