I want to download a csv file using a link automatically in a specified folder by running a cron job using PHP.
I tried the below code ,but it gets downloaded in download folder by default.
can any one show me the right way to do it.The code used is below.
$link="http://labcase.com/wrt/search.php?format=csv&sortby=reqnum|DESC&Search=non_closed_req&state[]=New&state[]=Pending%3A+Delivery&state[]=Pending%3A+Installation&state[]=On+Hold&state[]=Pending%3A+More+Info&state[]=Assigned&state[]=Working&state[]=Pending%3A+Approval&orgs[]=125&orgs[]=25&bldg[]=BGL04%2CBGL11%2CBGL12%2CBGL13%2CBGL14%2CBGL15%2CBGL16%2CBGL17%2CBGL20%2CBGL22%2CBGL25%2CBGL26%2CBGL43&business_unit=all";
header('Content-Disposition: attachment; filename=example.csv');
header("Content-Type: application/force-download");
header('Pragma: no-cache');
readfile($link);
You can use this:
file_put_contents("Tmpfile.zip", fopen("http://someurl/file.zip", 'r'));

Is it possible to display via PHP 2 pdf files in the browser? I want that the second file gets attached to the first file. With one file i did it with:
header("Content-Type: application/pdf");
header('Content-Disposition: inline; filename="filea.pdf"');
readfile(*path*);
I tried to attache the 2. file only with readfile but it didn´t worked. Is there a simple way to display the 2 files?
Try PDFtk Server. After you install it, you can execute it like this from your PHP script:
exec('pdftk filea.pdf fileb.pdf cat output filec.pdf');
header('Content-Type: application/pdf');
header('Content-Disposition: inline; filename="filec.pdf"');
readfile('filec.pdf');
I am trying this simple code to download csv file via my web page but didn't work.
<?PHP
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename=test.csv');
header('Pragma: no-cache');
echo readfile('test.csv');
?>
the error is "internet explorer can't find "csv_download.php" the file link on my web page
Click here to download the "CSV" file
anything missing?
Your PHP file is not at the URL you expect. Always set the full path where possible:
<a href="/csv_download.php">...
I have a htaccess password protected folder with several files in it. Users are not allowed to access all files, but are allowed to download their own.
Since i can't direct link the file and since copying / removing isn't a real solution, i thought i'd just open the file using file_get_contents and echo it back into the page using the right header. But.. i don't get it working.. Here is my code. The error i am getting is that when opening the file i get a "file is damaged" error from Acrobat.
<?php
$file = "cms/docs/5641-1.pdf";
header('Content-Description: File Transfer');
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename='.basename("exoticfilename.pdf"));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
if (file_exists($file))
{
echo file_get_contents($file);
}
?>
Also, in this example I am just using a PDF file, but there are several types of files. Therefore i should probably change the header depending on the file type. Is there a solution for that, or should i just use a very long if / else statement?
If there is another, better way, I am open for that.
UPDATE
The above works, but not with all files. Older PDF's (Acrobat 6) don't work, but Acrobat X files do. Same counts for the docx files. Some work, others don't. Very weird, since I am able to open all directly on my PC. I assume it has something to do with the application/pdf line (or application/vnd.openxmlformats-officedocument.wordprocessingml.document' for docx). All others, like images, work.
Since you are using htaccess/htpasswd to protect the directory from hot-linking leeches. You are inadvertanly blocking access to the files from an outside source such as a browser from the client side. Since the directory requires authentication to access the files within it, you need to script around it. In a sense authenticating through the script. I have seen it done before, and you can find one of many references on the subject here
http://koivi.com/php-http-auth/
but bottom line is htaccess and htpasswd over run your scripts even if on the same host machine, as they are in a lack of better description server level, ran before even php starts its process on a page load.
I'm trying to use the following code to create a zip file from a directory and serve it to the user via an http download:
// write the file
file_put_contents($path . "/index.html", $output);
// zip up the contents
chdir($path);
exec("zip -r {$course->name} ./");
$filename = "{$course->name}.zip";
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' .urlencode($filename));
header('Content-Transfer-Encoding: binary');
readfile($filename);
I am able to create the zip file, but downloading it over http is not working. If I download the zip file that's created using an ftp client then Mac's Stuffit Expander unzips the files just fine, but if I download it over http, the mac unzipper creates an endless loop. What I mean by this is say the file I download is called course.zip, then unzipping the file gives course.zip.cpgz and unzipping that file gives course.zip again..and on and on.
Anyone have any ideas?
Thanks!
I had this problem and it turned out the downloaded zip file had a new line inserted at the very beginning.
Solved by using ob_clean and flush functions
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: application/octet-stream");
header("Content-Disposition: attachment; filename=".basename($archive_file_name));
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($archive_file_name));
ob_clean();
flush();
echo readfile("$archive_file_name");
Re-zipping it every time it is requested is not a good idea. Try doing that only if the ZIP file does not exist already.
If is a volatile file or just a single small file you want to transfer compressed, try using ob_start('ob_gzhandler') instead, simplier, smaller, cleaner. The file is transfered compressed, but it is saved in its original format by the client-side.
Specifying the Content-Length header is needed to allow the downloader to know the end of the file, allowing progress control, detection of corruption of the file and avoiding the hang of the HTTP session (if Connection is in Keep-Alive mode), maybe the lack of this header is the root of the problem.
As suggested by karim79, I'll put my comment as an answer: what happens if you change the MIME type from application/octet-stream to application/zip?
Also, I see you're using a command line zip program, but you don't check for success of the zip, and also don't check if the file exists before attempting to send it out to the end users browser. Try hard coding a file name, manually using zip to guarantee a properly formed zip file, and then see if your code will spit it to your browser properly.
What you're seeing is that the archive utility is not recognizing the zip file as a zip file, and tried to zip up the zip archive itself. The second operation simply unzips the first file created, so never actually opening the file at all. This is due to the zip being corrupted.
It is possible that the browser somehow mangled the zip file (newline conversions anyone?) during the download process. As mentioned, check the mime type and use the php header() to set the correct MIME type (application/zip).
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);
