This question is for those who have used PHP library FPDF (http://www.fpdf.org ) to generate PDF documents using PHP. I am generating a PDF file using the php file 'my_file.php'. I want users to be able to download that PDF file. But in the browser the see the file in the address bar as ..somepath..../my_file.php . I want them to see it as a file with .pdf extension. Any idea how this can be done ?
when you create the object and then try to make output like this
$filePath = "files/cache/myPdf.pdf";
$pdf=new FPDF('p');
...
$pdf->Output($filePath,'I');
you can change and send the file name
To force download:
$pdf->Output('D'); //Force download and set filename as 'doc.pdf'
or setting your own filename:
$pdf->Output('MyFilename.pdf','D');
Your browser shall not open another tab whit yourpath/my_file.php
You can't change the browser address bar, but you can change the address on your server. For example if you're using Apache, there's mod_rewrite which allows you to do such things.
If your problem is that when downloading the file, the browser wants to save it as .php, you could use those headers to force the download and a filename.
header('Content-Type: application/octet-stream');
header('Content-Length: ' . FILESIZE_HERE);
header('Content-Disposition: attachment; filename=' . FILENAME.pdf_HERE);

$file_name = $_GET['title'];
$file_url = $_GET['url'] . $file_name;
header('Content-Type: video/octet-stream');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"".$file_name."\"");
readfile($file_url);
exit;
I'm using this code to download files in my site fetching from another websites.
It works if my url looks like:-
https://www.example.com/video_download.php?title=video.mp4&url=http://googlevideo.com/video/download/223689/289048
(example)
So, it starts downloading by fetching the video file from http://www.googlevideo.com/video/play/221589 to my site.
But my problem is that the file can be accessed if the person uses a PC.
Can I change the User Agent by using header()?
Is it possible?
So if I change the user agent into a PC user agent, so it can be downloaded from a mobile!
I'm sorry, but the User Agent has nothing to do with readfile() function. Readfile() will just throw the raw file input into your browser. Useful for e.g. rendering images through PHP to the client without having to expose the real file name.
Indeed, it is possible to render video to the client with readfile(), but using a HTML5 video tag will dramatically improve performance. This will also provide better mobile support.
Hope this helps you,
You can use stream_compy_to_stream
$video = fopen($file_url);
$file = fopen('videos/' . $title . '.mp4', 'w');
stream_copy_to_stream($video, $file); //copy it to the file
fclose($video);
fclose($file);
I wrote a class for downloading youtube video files. you can find it here.
I am saving a pdf file, and then attempting to download it using php.
The script seemed to work fine, but all of the sudden not anymore.
Can anybody see what I am missing?
PS: the file I am downloading is only 4.3kb big, so I assume that would be because it is not downloading at all. The actual file size should be bigger than this.
$pdf->output(ROOTDIR.'/modules/addons/statement_generator/reports/statement.pdf');
if($action=='print'){
$file_name = 'statement.pdf';
$file_url = "http://".$_SERVER['SERVER_NAME']."/modules/addons/statement_generator/reports/" . $file_name;
header('Content-Type: application/pdf');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"".$file_name."\"");
readfile($file_url);
exit;
}
The $pdf->output() call will already send the PDF to the client. The file will not be saved to your local folder (Didn't you checked at least this?) because you have to pass "F" as the snd parameter.
After that you try to read from an URL (!!!!) that does not exists and which maybe return a nicely styled 404 html response. Two issues here:
Why are you using http when you have the local path used some lines above? Use the local path only!
The content returned by the URL is append to the already send PDF which ends in a document mixed of PDF and HTML (the 404 response) -> corrupted PDF
Conclusion: Use "F" as the 2nd parameter and use the same path for both writing and reading and not a mix of local path and URL.
First post. I'm working on a project for a client where they have pdf files uploaded to a file structure (LAMP Stack) but the files have no extensions on them. Under the assumption that those files have to be PDF how would I get the browsers to understand that, and open them accordingly? Obviously with adding the file extensions this would suddenly work but I can't change the way their system works, it would result in too many changes and they are on a tight deadline. As for saving a temporary copy somewhere, I could do that, but I was hoping for a better solution. Is there a way to suggest to the browsers that they open a file a certain way?
Any thoughts guys/gals?
You just set the application type and file name in the headers, like so:
// This points to the file in question, note that it doesn't
// care whether it has an extension on the name or not.
$filePathOnDisk = '/path/to/your/pdffile';
// You can make this whatever you like, it doesn't have to
// be the same as the file name on the disk! This is the name of the file your end
// user will see when they are asked if they want to save. open, etc in the browser.
$fileName = 'file.pdf';
$data = file_get_contents($filePathOnDisk);
header("Content-type: application/pdf");
header("Content-disposition: attachment;filename=$fileName");
echo $data;
See PHP: stream remote pdf to client browser and Proper MIME media type for PDF files for reference as well.
Tested
You can use the following which will prompt the user to save the (PDF) file on their computer.
Notice the different file names.
One is the file that will be uploaded/prompted to the user download_example.pdf, while the other is the file without an extension as set in readfile('example');
<?php
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="download_example.pdf"');
readfile('example');
?>
Im trying to get a website to have a button that forces a download of a pdf.
Heres the html of the button:
<a href=scripts/download.php>
<input type="image" src="images/download.gif" alt="Submit button"/>
</a>
And the php script so far:
<?php
header('Content-Type: application/pdf');
header('Content-disposition: attachment;filename=documents/ECM_IT_ResumeDownload.pdf');
readfile('documents/ECM_IT_ResumeDownload.pdf');
?>
This seems to download the file fine but when I go to open it i get this error:
"Adobe Reader could not open 'documents_ECM_IT_ResumeDownload.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded)."
Any help would be greatly appreciated.
EDIT
Opened the pdf in a text editor and got this message:
"
Warning: readfile(documents/ECM_IT_ResumeDownload.pdf) [function.readfile]: failed to open stream: No such file or directory in html/scripts/download.php on line 4
"
The document is definitely there though. in html/documents/ECM_IT_ResumeDownload.pdf
$file_url = www.example.com/pdffolder/$pdfname;
header('Content-Type: application/pdf');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=".$pdfname);
readfile($file_url);
Try removing the path to the file and just leave the file name in the content:
header('Content-Type: application/pdf');
header('Content-disposition: attachment; filename=ECM_IT_ResumeDownload.pdf');
Have you tried getting rid of the closing PHP tag (the ?>) at the end? It will treat the page as a pure PHP page, removing any possible new lines that might accidentally get appended to the end of the output. This helped me when I was dynamically creating excel files for download, and they were downloading as corrupted. Check out this page for more information:
http://www.php.net/manual/en/language.basic-syntax.phptags.php
From your edited question, it seems like PHP is unable to find the file. Try using an absolute path to the file like so: "c:\blah\de\blah\bloo.pdf" or "c:/blah/de/blah/bloo.pdf". If one of those paths works and downloads correctly, your relative path is incorrect in some way.
I always use Gowon Patterson's download script, it also has hotlink protection:
http://by.gowondesigns.com/getfile/
By the way, a bit late, but to identify the problem properly here:
Your download script is at scripts/download.php and the file you want to download is at documents/[...].pdf.
Therefore, your readfile() function should be traversing to the parent directory (outside of scripts/), e.g. readfile('../documents/[...].pdf');.
Basically I wrote a script that generates a xml file based on user input. After the file is generated a download link appears like so:
Download File
But when clicked it opens the xml in the browser, I want it to start downloading when the link it clicked instead. Is there any way to achieve that?
Yeah, there is. It does require specifying some headers. Exactly how it works depends on what language you're using, but here's an example using php, taken off of php.net:
<?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');
?>
Basically, first we tell the client what type of file we're sending, then we tell the client that what we're sending is an attachment, and it's name, instead of it being a page to display, and then finally we print/read the file to the output.
Given that you're already using php to generate the xml file, I would suggest adding the header commands above to the code that generates the xml file, and see if that does the trick.
If you happen to be using Apache for your web server, and you always want to force downloading of XML files, there is a more efficient way to do what #chigley suggested. Just add the following to a .htaccess file.
<Files *.xml>
ForceType application/xml
Header set Content-Disposition attachment
</Files>
What happens when a browser sees a link is not dependent on the link, but rather on the target of the link. Your web server should send the appropriate header: Content-Disposition: attachment;filename="file.xml" to tell the browser that it should prompt to save the file instead of displaying it.
It depends on what the client computer does with XML files. If you doubleclick on a XML file, it will open in your browser probably.
download.php:
header('Content-Type: text/xml');
header('Content-Disposition: attachment; filename="file.xml"');
readfile('/path/to/file.xml');
HTML:
Download
