I have be trying to figure out what is wrong but every time i download the image and try to open it, it says that the file is corrupt.
$h is the path which is pulled from the database, the $h displays the image on the page successfully but I dont get why it wont download. Any ideas ??
header("Pragma: public"); // required
header("Cache-Control: private",false); // required for certain browsers
header('Content-Length: '. filesize("../".$h));
header('Content-Type: application/octet-stream');
header('Content-Disposition: inline; filename="'.md5($h).$ext.'"');
header('Content-Transfer-Encoding:binary');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
readfile("../".$h);
Maybe try to add the following 2 commands before your readfile line.
ob_clean();
flush();
readfile($file);
These lines were in the example for the PHP docs on readfile.
Try this:
$localPath = realpath("../$h");
if (!file_exists($localPath)) {
exit("Cannot find file located at '$localPath'");
}
header('Pragma: public'); // required
header('Content-Length: '.filesize($localPath));
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.md5($localPath).'.'.$ext.'"');
header('Content-Transfer-Encoding: binary');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0', false);
header('Cache-Control: private', false); // required for certain browsers
readfile($localPath);
exit;

For some reason, with this code:
header("Content-Type: text/x-vcard;charset=utf-8;");
header("Content-Disposition: attachment; filename=card.vcf");
header("Pragma: no-cache");
header("Expires: 0");
echo $vcard_serialized;
on chrome from Pc, it downloads card.vcf, but from mobile it downloads card.vcf.html... why?
I have the same issue, but now I already fixed it using the codes below:
header('Content-Description: Download vCard');
header('Content-Type: text/vcard');
header('Content-Disposition: attachment; filename='.$your_filename_here);
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();
echo $vcard_serialized; //echo the content
exit;
I Want to add download file in the site, but when I click on download It shows weird character. I dont know what the error is. I have added type application/octet-stream in my code. I think there is problem of permission but I have also set permission in c-panel :
Here is my file download code:
if(isset($_REQUEST["file"])){
$file = urldecode($_REQUEST["file"]);
$filepath = ABSPATH.'/wp-content/themes/xorisk/document_upload/'.$file;
if(file_exists($filepath)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($filepath).'"');
header("Content-Type: mime/type");
header('Expires: 0');
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header('Cache-Control: must-revalidate');
header('Pragma: public');
header("Content-Transfer-Encoding: binary");
header('Content-Length: ' . filesize($filepath));
readfile($filepath);
exit;
I have a document download site where I track files downloaded.
My problem is getting zip files to download through the script I am using. Every other file gets forced to download apart from zip files. When a zip file is pushed it just goes to the download.php page where the script is with no file being pushed out.
ob_start();
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($file);
exit;
Here is a code snippet that works for me:
if (strstr($_SERVER['HTTP_USER_AGENT'], "MSIE")) {
header('Content-Type: "application/octet-stream"');
header('Content-Disposition: attachment; filename="'.basename($file_url).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header("Content-Transfer-Encoding: binary");
header('Pragma: public');
header("Content-Length: ".filesize($file_url));
} else {
header('Content-Type: "application/octet-stream"');
header('Content-Disposition: attachment; filename="'.basename($file_url).'"');
header("Content-Transfer-Encoding: binary");
header('Expires: 0');
header('Pragma: no-cache');
header("Content-Length: ".filesize($file_url));
}
readfile($file_url);
Had similar problem, this quotes helped that time:
header('Content-Disposition: attachment; filename="'.basename($file).'"');
I was not using the base_name for the content disposition and length, I had the full path instead. Using base_name worked for me.
I have a problem with reading pdf file in Chrome by using PHP.
The following code is how I do in PHP
$path = "actually file path";
header("Pragma: public");
header("Expires: 0");
header("Content-type: $content_type");
header('Cache-Control: private', FALSE);
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header("Content-Disposition: inline; filename=\"$filename\"");
header('Content-Transfer-Encoding: binary');
header('Content-Length' . filesize($path));
ob_clean();
flush();
readfile($path);
In here, I set the Content-Disposition to inline. Because I want to display the pdf file if user browser have build-in pdf viewer plugin. As you may know, Chrome has build-in pdf viewer.
The problem is I have bunch of pdf files on the server. Only some of them can be viewed by Chrome. I can't figure out why others can not work the same way. I have checked the permission of each files. It looks like not the permission problem.
Is there anyone know what the problem is? Thank you.
I've been wrestling with this same issue. This is as close as I got to consistent results across browsers. I think that the reason you could be having problems is if some PDF's are too large for readfile() to handle correctly. Try this:
$file = "path_to_file";
$fp = fopen($file, "r") ;
header("Cache-Control: maxage=1");
header("Pragma: public");
header("Content-type: application/pdf");
header("Content-Disposition: inline; filename=".$myFileName."");
header("Content-Description: PHP Generated Data");
header("Content-Transfer-Encoding: binary");
header('Content-Length:' . filesize($file));
ob_clean();
flush();
while (!feof($fp)) {
$buff = fread($fp, 1024);
print $buff;
}
exit;
I had similar issue but I noticed the order matters. Seems that ; filename= must have quotes around it, Content-Disposition: attachment Try this:
$file = "/files/test.pdf";
$finfo = finfo_open(FILEINFO_MIME_TYPE); // return mime type ala mimetype extension
$mime = finfo_file($finfo, $file);
header('Pragma: public');
header('Expires: 0');
header('Content-Type: $mime');
header('Content-Description: File Transfer');
header('Content-Disposition: attachment; filename="'.basename($file).'"'));
header('Content-Transfer-Encoding: binary');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Content-Length' . filesize($file));
ob_clean();
flush();
readfile($file);
i've fixed this way
$path = 'path to PDF file';
header("Content-Length: " . filesize ( $path ) );
header("Content-type: application/pdf");
header("Content-disposition: inline; filename=".basename($path));
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
ob_clean();
flush();
readfile($path);
Had the same problem, chrome didn't display the inline PDF, stuck at loading. The solution was to add header('Accept-Ranges: bytes').
My complete code:
header('Content-Type: application/pdf');
header('Content-Disposition: inline; filename="'.$title.'"');
header('Content-Transfer-Encoding: binary');
header('Content-Length: '.filesize($file));
header('Accept-Ranges: bytes');
header('Expires: 0');
header('Cache-Control: public, must-revalidate, max-age=0');
For me adding the following header fixed this annoying Chrome bug (?):
header('HTTP/1.1 200 OK');
After hours wasted this...i added comments to point out that #Kal has the only solution that worked. But somehow that's not enough...this is such an impossible and frustrating problem when Chrome does this:
Error Failed to load PDF document. Reload
Here is the diff that ended the torture.
- // Waste time with chrome:
- header("Content-type:application/pdf");
- header("Content-Disposition:attachment;filename=$file_basename");
- readfile($file);
exit();
---------------------------
+ // Deliver the file:
+ header('Pragma: public');
+ header('Expires: 0');
+ header('Content-Type: $mime');
+ header('Content-Description: File Transfer');
+ header('Content-Disposition: attachment; filename="'.basename($file).'"');
+ header('Content-Transfer-Encoding: binary');
+ header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
+ header('Content-Length'.filesize($file));
+ ob_clean();
+ flush();
+ readfile($file);
exit();
For about thirty minutes i fooled with various variations of this...but i could not pin it down to "Add HTTP 200", not to "add bytes", not to "quote your filename", not to "separate the file ending". None of those worked.
(Thank you again #Kal).
I was having this issue, struggled for almost 6 hours and finally got it working. My solution is similar to the above answers but the above answers are not completed. There are three steps to solve this issue.
Step 1.
Go to php.ini file and add this line.
output_buffering = False
Step 2.
This error comes if you are opening a large PDF file. So, to solve this, just before adding headers, make sure you put these two lines.
set_time_limit(0);
ini_set('memory_limit', '100M'); //the memory limit can be more or less depending on your file
Step 3.
Add below headers and the code to read the file, so the final code would like this.
set_time_limit(0);
ini_set('memory_limit', '100M');
$file = "path/to/file.pdf";
header('Content-Type: application/pdf');
header('Content-Disposition: inline;
filename="yourfilename.pdf"'); //not the path but just the name
header('Content-Transfer-Encoding: binary');
header('Content-Length: '.filesize($file));
header('Accept-Ranges: bytes');
header('Expires: 0');
header('Cache-Control: public, must-revalidate, max-age=0');
ob_clean();
flush();
readfile($file);
exit();
100% working solution. If you have any issues, let me know :)
Generally, browsers show the image and pdf files without embedding them in html. I need some codes to make these files not to show in the browsers but make them downloadable like doc files.
Please help me out with this.
This isn't up to you, it is up to the browser.
However, you can make a suggestion as to what to do with it by setting the content-disposition header...
header("Content-Disposition: attachment; filename=\"yourfilename.pdf\"");
Read the doc on the header() function: http://php.net/manual/en/function.header.php
In case this isn't clear... this is for whatever resource is returned by the PHP document. You may need a readfile() in there to do what you are trying to do.
Set a couple of headers:
$filename = ...;
$mime_type = ...; //whichever applicable MIME type
header('Pragma: public');
header('Expires: 0');
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: $mime_type");
header('Content-Length: ' . filesize($filename));
readfile($filename);
<?php
header('Content-disposition: attachment; filename=myfile.pdf');
header('Content-type: application/pdf');
readfile('myfile.pdf');
?>
You want to send a content type header to make the browser download the file.
If you aren't' generating it dynamically, you will need to read it off the disk first.
$fullPath = "/path/to/file/on/server.pdf";
$fsize = filesize($fullPath);
$content = file_get_contents($fullPath);
header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers
header("Content-Type: application/pdf");
header("Content-Disposition: attachment; filename=\"".basename($fullPath)."\";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".$fsize);
echo $content;
try this one :
$file = 'youfile.fileextention';
if (file_exists($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;
