Failed to load pdf file when uploaded on server. Codeigniter hmvc - php

i have this show uploaded pdf file on my localhost my view is
<?php
// retrieve your info ecc.
$url = $content->PATH;
$filename = $content->FILE_NAME;
header('Content-type: application/pdf');
header('Content-Disposition: inline; filename="' . $filename. '"');
header('Content-Transfer-Encoding: binary');
header('Accept-Ranges: bytes');
#readfile($url);
?>
just to be clear
$content->PATH and $content->FILE_NAME are data from database
$content->FILE_NAME is $file_name = $file_data['file_name'];
and $content->PATH = base_url().'uploads/pdf/'.$file_name;
now it perfectly works on my localhost, but on the server, it looks like this
the link to this is
$row[] = '&nbsp Show File";
what is the error of this ? how can i solve this?

Try with CI built-in download helper class
$this->load->helper('download');
force_download($file_name);

Download RAR file from a link (server)

I'm trying to download a .rar file from a cloud (for sake of simplicity I'm using my google drive storage), the file is downloading perfectly, but once i want to open the .rar file , it says that "the archive is either unknown format or damaged" , tried all methods even cURL ,but it didnt want to work,
Im just wondering what I'm missing in my code, thank you
<?php
$filename = 'stu.rar';
if ( file_put_contents( $filename,file_get_contents("mygoogleDriveLink/search?q=stu.rar"))) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.$filename.'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
//header('Content-Length: '.filesize($filename));
readfile($filename);
//print_r("this is ".$id);
exit();
}
else{
echo "err";
}
You may use file_put_contents to save the file to the server first, before you stream it to your browser.
if you do not need to stream to user's web browser, then you may remove the codes from start streaming to end streaming.
Please try the following:
<?php
// Initialize a file URL to the variable
$url = 'http://www.xxxxxxxxxxx.com/xxxxx.rar';
// Use basename() function to return the base name of file
$file_name = basename($url);
// Use file_get_contents() function to get the file
// from url and use file_put_contents() function to
// save the file by using base name
if(file_put_contents( $file_name,file_get_contents($url))) {
// File successfully saved in the server
// start streaming . The following is to stream and save to browser
$file_name = $file_name;
$file_url = $file_name;
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"".$file_name."\"");
readfile($file_url);
exit;
/// end streaming
}
else {
echo "File downloading failed.";
}
?>

PDF file is not view in correct format in browser using PHP Header function

I am using following code for view pdf file in browser but file is not showing correctly.
<?php
$file = 'google.pdf';
$filename = 'google.pdf';
header('Content-type:application.pdf');
header('Content-Disposition: inline; filename"' . $filename .'"');

That's an invalid content type, you should be using application/pdf
// change this
header('Content-type:application.pdf');
// to this
header('Content-Type: application/pdf');

How to download a text file on link click in codeigniter

I have text file contains Sample of CSV file format, I want my users can download that file on a link click.
This file resides in this folder stucture:
assets->csv->Sample-CSV-Format.txt
This is the code that I have tried to far:
<?php
$file_name = "Sample-CSV-Format.txt";
// extracting the extension:
$ext = substr($file_name, strpos($file_name,'.') + 1);
header('Content-disposition: attachment; filename=' . $file_name);
if (strtolower($ext) == "txt") {
// works for txt only
header('Content-type: text/plain');
} else {
// works for all
header('Content-type: application/' . $ext);extensions except txt
}
readfile($decrypted_file_path);
?>
<p class="text-center">Download the Sample file HERE It has a sample of one entry</p>
This code is downloading the file on page load instead of link click. Also, it is downloading the whole html structure of the page I want only the text what I have written in text file.
Please guide where is the issue?
You can do this simply in by HTML5 download atrribute . Just add this line in your downloading link .
HERE
You can do it like this, it won't redirect you and also works good for larger files.
In your controller "Controller.php"
function downloadFile(){
$yourFile = "Sample-CSV-Format.txt";
$file = #fopen($yourFile, "rb");
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=TheNameYouWant.txt');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($yourFile));
while (!feof($file)) {
print(#fread($file, 1024 * 8));
ob_flush();
flush();
}
}
In your view "view.php"
Download
make it like this
someother_file.php
<?php
$file_name = "Sample-CSV-Format.txt";
// extracting the extension:
$ext = substr($file_name, strpos($file_name,'.')+1);
header('Content-disposition: attachment; filename='.$file_name);
if(strtolower($ext) == "txt")
{
header('Content-type: text/plain'); // works for txt only
}
else
{
header('Content-type: application/'.$ext); // works for all extensions except txt
}
readfile($decrypted_file_path);
?>
some_html_page.html
<p class="text-center">Download the Sample file HERE It has a sample of one entry</p>
To my view its better to have the download code to the client side, than to have a controller-method written for this.
you can use this ref
public function getTxt()
{
$this->load->helper('download');
$dataFile = "NOTE87";
$dataContent = array();
$dt = "Date :23/07/2021";
$dataContent= array(
"\n",
"\t\t\tUTI AMC Limited\n",
"\t\tDepartment of Fund Accounts\n",
"\n",
"\tReissue of Non Sale Remittance - Axis Bank Cases\n",
"\n",
"\t\t\t\tDate :".$dt."\n",
"\n",
);
force_download($dataFile,implode($dataContent));
}

Download File in Yii

I am trying to write a script in Yii for downloading files from the server.
The files are located in webroot of the Yii project,
but I got every time file not exist error, could anyone see where is wrong:
public function actionDownload($id) {
$audio = Audio::model()->findByPk($id);
$file = Yii::getPathOfAlias('webroot') . $audio->path;
if (file_exists($file)) {
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' . $audio->path);
header('Content-Length: ' . filesize($audio->path));
$audio->downloaded = $audio->downloaded + 1;
$audio->save();
}else{
echo "file not exist: ".$file;
}
exit;
}
error I got is:
file not exist: /var/www/vhosts/ikhwanbiz.org/httpdocs/userfiles/reklames/media/deneme/sen%20dep%20olmisem.mp3
Thanks
Regards
Bili
Bili, this works well for me and seem to be fine on most browsers.
$filename = 'your_file_name.csv';
header('Content-Disposition: attachment; charset=UTF-8; filename="'.$filename.'"');
$utf8_content = mb_convert_encoding($content, "SJIS", "UTF-8");
echo $utf8_content;
Yii::app()->end();
return;
Hope it helps, good luck!
It looks like the filename portion $audio->path is URL-encoded, while the name of the actual file on the server is not. You should fix it at the source (no idea where that path is set from), but in the meantime an easy workaround would be to write
$file = Yii::getPathOfAlias('webroot') . urldecode($audio->path);
This is more of a php question than a yii one.
for eg,
<?php
header("Content-disposition: attachment; filename=huge_document.pdf");
header("Content-type: application/pdf");
readfile("huge_document.pdf");
?>

txt file that I download is empty

The code below is for two purposes
1) I save a text file on my server in a folder named "backup_db" its working fine mean when I open that text file it contain all the data
2) At the same time i also make this file downloadable for a user so that he could download it for himself and could save it on his hard disk and according to my wish its downloading but unfortunately the .txt file saved on my hard disk is, when open its empty and i don't know why please help me out
//save file
$handle = fopen('backup_db/db-backup-'.date('d-m-Y_H-i-s').'-'.(md5(implode(',',$tables))).'.txt','w+');
$rr = fwrite($handle,$re);
//fclose($handle);
$ww = "db_backup".$rr.".txt";
//$handle = "";
header('Content-Disposition: attachment; filename=' . urlencode($ww));
header('Content-Type: application/force-download');
header('Content-Type: application/octet-stream');
header('Content-Type: application/download');
header('Content-Description: File Transfer');}}
You only set the HTTP header but did not write the file into the response body. Use either fpassthru() or readfile() to write the content of the file directly to the response.
Sample (taken from php.net)
<?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($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
flush();
readfile($file);
exit;
}
?>
BTW:
Settings the same header multiple times simply overwrites the value set before unless you set the second parameter of header() to false.
Your code
header('Content-Type: application/force-download');
header('Content-Type: application/octet-stream');
header('Content-Type: application/download');
results in the following header:
Content-Type: application/download
Sending a file namein the header just gives the user a suggested filename. Try echoing out the contents of the file.
You should add
header("Content-Length: $size")
where $size is size of yout file in bytes.
Check this
ex :
$filename = urlencode($fileName); //download.txt
header("Content-Disposition: attachment; filename=\"" . $filename. "\";" );
