well I'm just wondering how I can get an mp3 download to start instantly, as oppose to it simply starting to play in the browser when you directly go to it.
Preferably using php headers.
So essentially when you click the file, I want a download box to appear saving save etc. Right now it just opens and starts playing in the browser.
Thanks
You'll need to create a PHP file that "redirects" to the MP3 file, and point your links to that PHP file.
Code as below:
<?php
header('Content-type: audio/mpeg');
header('Content-Disposition: attachment; filename="fileName.mp3"');
readfile('originalFile.mp3');
?>
Note: The line that sets the Content-Disposition header is the critical one.

I'm outputting a PDF via PHP with the following code. $file is an object that contains data pertaining to the file being displayed.
header('Content-type: application/pdf');
header('Content-disposition: inline; filename="'.$file->name.'"');
#readfile($file->ServerPath());
My issue is that when I go to download the file in Chrome it will occasionally try to save the page instead of the PDF.
For example, say the URL that is displaying the file is mywebsite.com/file?file_id=1234. Most of the time it will try to save the file correctly as "file_name.pdf". However, sometimes chrome will try to save the file as "file" with no extension. This seems to happen randomly.
If it makes any difference the page displaying the file is being opened in a new tab. The issue happens regardless of whether I redirect via PHP or Javascript.
I really need to resolve this issue, as these PDFs will be accessible by users.
Thanks in advance.
I have this download script running that allows people to click on a button and download a file without any new html pages opening. It all works well. Here is the script.
<?php
header('Content-disposition: attachment; filename=brochure-company-details.pdf');
header('Content-type: pdf');
readfile('brochure-company-details.pdf');
?>
However, I really want to be able to run the statcounter script at the same time, so as to document who is downloading the file. The Statcounter script works well enough when an html page opens and runs through its function. But I down't want a new page to open. I just want the download to start. The user experience will be that they only have the file download and without them knowing the statcounter will record the event.
Can you help?
What you want is not possible. (executing javascript on pdf download) Statcounter is an script and is executed by the browser by being included on the html. If you download a pdf file, you are not executing any js.
However, statcounter can see what links are pressed and therefore you can find which files were downloaded; as long your files are downloaded by using regular links on an html that has statcounter included. You don't need to do anything at all, they would be counted by default.
The idea Dachi gave, is to add an sql insertion to that php code of yours.
<?php
$dbh = new PDO("sqlite:/path/to/database.sdb");
//Put the insertion code here.
//Insert things like the IP, the login name, the time, etc.
header('Content-disposition: attachment; filename=brochure-company-details.pdf');
header('Content-type: pdf');
readfile('brochure-company-details.pdf');
That works too, and is a good choice if you are allowing downloads by not using regular links or not from an html that has statcounter.
This seems like it should be simple. I have a set of files I have to store outside of the webroot and have an access script to call them. I also need to sometimes tell a PDF that must be called via this proxy script to open at a specific page. Releveant part of the script below:
header('Content-type: application/pdf');
header('Content-Length: ' . filesize($file));
header('Content-Disposition: attachment; filename="'.$file_name.'"');
readfile($file);
$file_name is just the basename() of the file, and $file is the path to the file, with #page=2, or #page=10, or whatever appended to it. If I remove the hashtag portion, the script works fine and the PDF opens with no errors. When the hashtag portion is there, all the programs tell me the PDF has been corrupted and can't be open.
I can't seem to find anything on here or Google as to what I need to do. Do I need to set an additional header to simulate the hash tag? Use exec() to call some command line code instead of using readfile()?
Any insight would be greatly appreciated.
You have to append the #page=2 (or whatever page you want to open) to the URL in the browser, not the filename in the proxy-script.
You currently try to open a file myFile.pdf#page=2 from the filesystem that does not exist as the filename is myFile.pdf
The feature to open a pdf-file on a specific page on the other hand is implemented in the browser or it's PDF-plugin. Therefore the information which page to open has to be given to the browser via the URL. So you should call your proxyscript like this: http://example.com/proxy.php?myFile.php#page=2
Update:
If you want to download the file and open it at a specific page every time the file is opened from the local file-system of the user, you will have to edit (or recreate) the PDF-File.
On my web server, I have a bat (harmless) file.
And I have code,
Test Bat File
But when the user clicks, it shows the code instead of downloading the file.
You have to right click "save as.." to download the bat file.
Is there way that when a user clicks, it downloads (not having to right click save as)?
Maybe a pop up window that asks user if he/she wants to download the file or not?
you could write a php file, which adds a content-disposition header, sets the mime type to something binary and echo the files content.
Example:
file.php
$batchfile = file_get_contents('batchlocation');
$size = strlen($batchfile);
header('Content-Disposition: attachment; filename="downloaded.bat"');
header('Content-Type: BAT MIME TYPE or something like application/octet-stream');
header('Content-Lenght: '.$size);
echo $batchfile;
You can do so through setting the file in the PHP header() function.

How to Automatically Start a Download in PHP?
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');
