In Joomla auto updater the file is requested from one domain
http://download.abc.com/?ext=addmenu&src=core&pro=1&file=update.zip
which then downloads a different file
/mnt/storage/vhosts/newdomain.com/httpdocs/tmp/addmenu-v1.1.4.zip
I've been trying to mimic this effect by calling a file release.php which is
header("Location: /addmenu/updates/com_addmenu.zip");
but it just downloads release.php and not com_addmenu.zip
I've also tried it with
header('HTTP/1.1 307 Temporary Redirect');
before the header(Location
But I can't get it to work this way. I'm guessing that I'm not able to substitute one file for another but I'm hoping someone can help.
thanks
I understood that you have a zip file on your server which shall be downloaded under a different name by the visitor's browser when s/he opens up your webpage.php.
<?php
$file_url = '/addmenu/updates/release.zip';
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary");
header('Content-disposition: attachment; filename=com_addmenu.zip');
readfile($file_url);

I have a php page which downloads zip files. Normally after the download, it automatically revert back the user to a previous page(myfiles.php) using header('location:myfiles.php');.
When I execute the page, it bring me to myfiles.php but the download pop up won't show up, thus preventing me to download my zip file. When I remove the line header('location:myfiles.php');, I am able to download my zip file as expected.
Below is an extract of my code.
//Some codes
if(file_exists($zip_name)){
// push to download the zip
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
readfile($zip_name);
// remove zip file is exists in temp path
unlink($zip_name);
}
session_start();
$_SESSION['correct']="Files downloaded sucessfully";
header('location:myfiles.php');
Can you please help me finding a way to fix it? Thank you.
Think about what those headers are doing
These 2 and the readfile
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
readfile($zip_name);
are sending a file to the current page that is on the browser.
This one, which will run as well as the code above
header('location:myfiles.php');
attempts to tell the browser to go to another page. If it did do that then the file you sent to the browser would just disappear
So basically done together as one flow, they do not make sense!
Also you cannot send a header('location:...) after any actual data has been sent to the browser, which of course you did when you ran the readfile($zip_name);
I want to make a website, which only allows authentic users to download files from the browser. And any one else cannot download the file.
I have uplaoded the files with 000 access, which will restrict the users, but how to give permissions only to authentic users.?
Can anyone help me with it?
You don't need to give a link to physical folder of a file. You may emulate it with such code(example of png):
header("Content-Type: application/octet-stream; ");
header("Content-Transfer-Encoding: binary");
header('Content-Disposition: attachment; filename="name.png"');
readfile($fileaddress);
I have a code which force download a pdf file. Code below
$file_name = 'Bv_Ebook.pdf';
$file_url = 'http://' .$_SERVER['HTTP_HOST'].'/sites/default/files/'. $file_name;
header('Content-Type: text/html');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"".$file_name."\"");
readfile($file_url);
This code works on our beta server and the pdf is downloaded and can be opened.
On our live server same code downloads the pdf but pdf file cannot be opened, it says:
Unable to open document
File type plain text document (text/plain) is not supported
I have gone though force download pdf and apache headers setting but nothing seems to work.
Any idea what could be the issue?
Check file permission using is_readable() to check if the file is accessible or not. If accessible then check below :
Can you please try to modify your headers to the following:
//We'll be outputting a PDF.
header('Content-type: application/pdf');
//PDF name.
header('Content-Disposition: attachment; filename="'.$file_name.'"');
Then do a file read or what ever, in my case I have used file_get_contents(file_path) + echo to display the content and worked as a charm.
I'm trying to create a file download page. This page when requested should prompt the user to download a file. Here is the source code for the page:
<?php
header('Content-disposition: attachment; filename=zip.zip')
header('Content-type: application/zip');
readfile('zip.zip');
?>
This works ok.
The problems starts when I want to move the file zip.zip from the folder where this script is in. I tried using relative and absolute URLs but I always get strange results,
the browser still prompts for file download but somehow it's just an odd file name converted from the URI I supplied somthing like ".._.._files_zip.zip instead of ../../files/zip.zip.
Any suggestions why this happens?
Thanks
Use basename to get just the file name:
$file = '../../files/zip.zip';
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Type: application/zip');
readfile($file);
For example, if I set some headers to download a file from my server I would do
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="downloaded.pdf"');
And then just output the data of the file
Is it possible to set a remote url in the Content-Disposition?
Example header('Content-Disposition: attachment; filename="http://remote.location/downloaded.pdf");
Or am I just thinking about it in the wrong way?
No, you would just do a 302 redirect.
No.
As Matthew suggested is to use redirect.
Other option is download file from script, then just output the downloaded file.
