I am not able to download the CSV file. I couldn't find any errors. please help
Why not just use force_download() helper function of CI. LINK
Try changing header in your code.
header('Content-Description: File Transfer');
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename='.$filename);
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($filename));

I created a simple file to download files.
I have the following code:
function DownloadFile($file) { // $file = include path
if(file_exists($file)) {
header('HTTP/1.0 200 OK', true, 200);
header('Content-Description: File Transfer');
header('Content-Type: application/zip');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
ob_clean();
flush();
readfile($file);
exit;
}
}
The problem is if I try to download files over 40-50MB the file is downloaded blank(0KB) but if I try below 40MB it is working perfectly.
What is the problem?
Like explained in this article https://www.sitepoint.com/community/t/php-file-size-download-limit/6541 you need to set
memory_limit = 128M
post_max_size = 300M
in php.ini file
The solution:
function DownloadFile($file) { // $file = include path
if(file_exists($file)) {
header('HTTP/1.0 200 OK', true, 200);
header('Content-Description: File Transfer');
header('Content-Type: application/zip');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: chunked');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
ob_end_flush();
if ($fd = fopen ($file, "r")) {
set_time_limit(0);
ini_set('memory_limit', '1024M');
while(!feof($fd)) {
echo fread($fd, 4096);
flush();
}
}
}
}
I am trying to download a zip file using headers. But it returns some special character's.
I tried the below code.
$filepath='http://localhost/mb/inc/tmp/liberty/xml_invoice.zip'
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="test.zip');
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($filepath));
ob_clean();
flush();
readfile($filepath);
exit();
when i run this code i am getting output like some special characters.like below
�Q�s�+k�X�ߡB�R�EE����m��#;Ok����A���R�2vZ�j�F�Mo� C�
If you want to deliver a ZIP file then you need to use also the correct MIME content type!
$filename = "xml_invoice.zip"
$file = "C:\wamp64\www\mb\inc\tmp\liberty\{$filename}";
header("Content-type: application/zip");
header("Content-Disposition: attachment; filename={$filename}");
header("Content-length: " . filesize($file));
header("Pragma: no-cache");
header("Expires: 0");
readfile($file);
try this: give path to your zip file.
$filepath = "/path/to/some_file.zip";
$file_name = basename($filepath);
header("Content-Type: application/zip");
header("Content-Disposition: attachment; filename=$file_name");
header("Content-Length: " . filesize($filepath));
readfile($filepath);
exit;
I have a problem with download script
when I download any file it is save with 0kb.
Any ideas? Here is my PHP script
<?php
$file = $_GET['fname'];
$fullpath = get_bloginfo('template_url')."/application/display/1358947404.pdf";
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($fullpath));
header('Expires: 0');
header('Cache-Control: must-revalidate');
ob_clean();
flush();
readfile($fullpath);
?>
Please add content-length header as well .
Please try this:-
<?php
$file = $_GET['fname'];
$fullpath = get_bloginfo('template_url')."/application/display/1358947404.pdf";
$headers = get_headers($fullpath, 1);// use file absolute path here
$fsize = $headers['Content-Length'];
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($fullpath));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header("Content-Length: " . $fsize);
ob_clean();
flush();
readfile($fullpath);
?>
Try below code hope it will help you.
I have tested this in my localhost.
$file = $_GET['fname'];
$fullpath = get_bloginfo('template_url')."/application/display/1358947404.pdf";
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($fullpath));
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($fullpath));
ob_clean();
flush();
readfile($fullpath);
I was trying to write a script through which user can download the image directly.
Here is the code i end up with,
<?php
$fileContents = file_get_contents('http://xxx.com/images/imageName.jpg');
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.urlencode("http://xxx.com/images/imageName.jpg"));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($fileContents));
ob_clean();
flush();
echo $fileContents;
exit;
?>
But everytime i hit the url for the above script in the browser it returns a file with zero byte data.
would you like to help me to resolve this problem ?
Try the code below
<?php
$file_name = 'file.png';
$file_url = 'http://www.myremoteserver.com/' . $file_name;
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"".$file_name."\"");
readfile($file_url);
?>

I notice that you use filesize on the contents of the file instead of at the filename itself;
Your code would work if it was:
<?php
$filename = 'http://xxx.com/images/imageName.jpg';
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.urlencode($filename));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($filename));
ob_clean(); // not necessary
flush(); // not necessary
echo file_get_contents($filename); // or just use readfile($filename);
exit;
?>
I try to use php to force the image jpg file download, I have implemented eth following code:
html
<a href = "filedownload.php?src=uploads/myimage.jpg&download=true>download this file</a>
download.php
<?php
ob_start();
include_once 'functions.php';
if (isset($_GET['download']) && $_GET['download'] == 'true')
{
$src = sanitizeString($_GET['src']);
header('Content-Description: File Transfer');
header('Content-Type: image/jpeg');
header('Content-Disposition: attachment; filename='.basename($src));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: public');
header('Pragma: public');
}
?>
Suppose the full path of the image is "www.example.com/smith/topic/uploads/myimage.jpg", I have recieved the right image name and the download window is appeared as well, but the image is corrupt and with 1KB size, any one could tell me why, thanks a lot.
Here you are example how to use readfile function
<?php
$file = 'monkey.gif';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
exit;
}
?>
You need some code that actually sends over the file. See e.g. readfile or fpassthru
Try to use:
header("Content-Disposition: attachment; filename=\"".basename($fullPath)."\";" );
