When I click on the file, I can view it in browser. When I click download, it says "failed to load the pdf document".
$file = "uploads/14204-2-002.pdf";
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$mime = finfo_file($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);
Try this one(HTML5 and no Internet explorer).
In your HTML code you can use this line:
<a href="/images/myw3schoolsimage.jpg" download="w3logo">
Specify a value for the download attribute, which will be the new filename of the downloaded file ("w3logo.jpg" instead of "myw3schoolsimage.jpg")

You can make a curl request on a php file who create, save the word and return the path, then use js to make a auto-click on a hidden link who you have set the "href=" with the path and have the attribute "download=your_file_name".
Create a tmp folder the same directory youhave the code and add this
objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'Word2007');
$objWriter->save('tmp/helloWorld.docx');
$file = 'tmp/helloWorld.docx';
if (file_exists($file)) {`enter code here`
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
I Want to add download file in the site, but when I click on download It shows weird character. I dont know what the error is. I have added type application/octet-stream in my code. I think there is problem of permission but I have also set permission in c-panel :
Here is my file download code:
if(isset($_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 am using the following code, to access a file which exists
$file = 'monkey.gif';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
It downloads fine, but when opening the image viewer is refusing to open stating its not a gif file. Is
I think you should change the Content-Type to 'image/gif'
I found that there was a print elsewhere in the code so when it was forcing the download it was corrupted. Removing the print worked.
Hi I am trying to allow download a demo file which is related to a product. my code is like this
if(isset($_POST['submit'])){
$root = $_SERVER['DOCUMENT_ROOT'];
$path = "/download/";
$path = $root.$path;
$filename = $demo;
$file = $path.$filename;
header('Content-Type: application/force-download');
header("Content-Transfer-Encoding: Binary");
header("Content-Disposition: attachment; filename=\"".basename($file)."\";" );
header("Content-Length: ".filesize($file));
readfile($file);
}
I am able to get file name which is associated with the product by
$demo
After user submits his information, download will start automatically. Now this is downloading a non existing file or corrupted file with the proper file name. please help
<?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;
}
?>
As you can see Content type is application/octet-steam meaning file is byte by byte encoded. Also the cache headers are set. Then headers are forcefully sent by ob_clean();flush(); and then the file is read.
The file_exists is there to ensure that given file exists. You should also try not not thrust user input as they could easy write names for your php codes and download EACH file. And with ../ in names of the files, even your documents or system files and so on.
I'm trying to create a download link for a PDF file. It works fine if Adobe Reader is installed, but if I uninstall it, it tries to open in browser and fails.
Please tell me what is the actual problem about this?
Thanks in Advance.
The problem is that when adobe reader is installed than it automaitcally gets the header of .pdf file and show the file.
You can use this.It will always prompt to download the file ..
$path="uploads/";
$actualfilename=$path.$row["name"];
//name of the file or location of file..
if($typeofview=="download") {
#readfile($actualfilename);
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="' . $actualfilename. '"');
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($actualfilename));
header('Accept-Ranges: bytes');
exit;
}
This is a duplicate of this question but here is the answer:
$path_to_file = '/var/www/somefile.pdf'; //Path to file you want downloaded
$file_name = "somefile.pdf"; //Name of file for download
header('Pragma: public'); // required
header('Expires: 0'); // no cache
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header("Content-Type: application/octet-stream");
header('Content-Disposition: attachment; filename="'.$file_name.'"');
header('Content-Transfer-Encoding: binary');
readfile($path_to_file);
die();
