I need help because I got an error message like "call to a member function mysql query on resource"
Here is my code:
<?php

$query = "SELECT * FROM kinerja WHERE id_data = $id_data";
$hasil_data = $koneksi->query($query);
if ($hasil_data->num_rows > 0) {
// output data of each row
while($row = $hasil_data->mysql_fetch_assoc()) {
$filename = $row['nama_file'];
}
}
$path = "../admin/files/"; // change the path to fit your websites document structure

I need help for this code, I really apreciate any help. Sorry for my bad English.
It looks like the error is somewhere in koneksi.php. I would guess it's near the function query() in that class. If you include that class it would be easier to spot the error.

I have tried all sorts of codes I've found but nothing has worked for me...
When I use readfile() or fopen() or something like this:
function makeDownload($file, $dir, $type) {
header("Content-Type: $type");
header("Content-Disposition: attachment; filename=\"$file\"");
readfile($dir.$file);
}
... A download is started but the file is always empty...
here's the last code I've tried:
$filename = "gandalf.jpg";
// define error message
$err = '<p style="color:#990000">Sorry, the file you are requesting is unavailable.</p>';
if (!$filename) {
// if variable $filename is NULL or false display the message
echo " filename NULL";
echo $err;
} else {
// define the path to your download folder plus assign the file name
$path = 'upload/'.$filename;
// check that file exists and is readable
if (file_exists($path) && is_readable($path)) {
echo "file exists";
// get the file size and send the http headers
$size = filesize($path);
header('Content-Type: image/png');
header('Content-Length: '.$size);
header('Content-Disposition: attachment; filename='.$filename);
header('Content-Transfer-Encoding: binary');
// open the file in binary read-only mode
// display the error message if file can't be opened
//readfile($path.$filename);
$file = # fopen($path, 'rb');
if ($file) {
// stream the file and exit the script when complete
fpassthru($file);
exit;
} else {
echo $err;
}
} else {
echo $err;
}
}

I use google chrome
I need your help for this little project: Link to Project
When you click on a file in the drop down appears "herunterladen" (download in german) here is where I want to start the php download code
I just need the most basic download function for PHP... why is there an upload example on w3schools but NOT a download example? oO
$fileSource= $_GET['fileSource']; //If you are passing the filename as a URL parameter
$fileSource= "sample.pdf" //If the filename is fixed in the current folder
if($fileSource) {
$filesize = filesize($fileSource);
$path_parts = pathinfo($fileSource);
$ext = strtolower($path_parts["extension"]);
switch ($ext) {
case "pdf":
header("Content-Disposition: attachment;
filename=\"".$path_parts["basename"]."\""); // use 'attachment' to
force a download
header("Content-type: application/pdf"); // add here more headers
for diff. extensions
break;
default:
header("Content-type: application/octet-stream");
header("Content-Disposition: filename=\"".$path_parts["basename"]."\"");
}
if($filesize) {
header("Content-length: $filesize");
}
readfile($fileSource);

So here i'm trying to send to the client some files received in a array from javascript. My problem is that i cannot redefine the filename (since its a header). So for example, i wanna send 3 files to the client, the first one is sent, then i got a error for the 2 last. Does anyone have idea how to fix it? Here is my php code:
PHP
<?php
ignore_user_abort(true);
set_time_limit(0); // disable the time limit for this script
$path = "../temp/"; // change the path to fit your websites document structure
$data = escapeshellarg($_GET['File']);
$data = str_replace("\\","",$data); // remove useless characters inserted
$data = str_replace("\"","",$data); //
$dl_file = explode(",", $data);
header("Content-type: application/octet-stream");
header("Cache-control: private"); //use this to open files directly
header('Pragma: private');
for($i = 0; $i < count($dl_file); $i++)
{
$fullPath = $path.$dl_file[$i];
$path_parts = pathinfo($fullPath);
header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\"",true);
if ($fd = fopen ($fullPath, "r"))
{
$fsize = filesize($fullPath);
$path_parts = pathinfo($fullPath);
$ext = strtolower($path_parts["extension"]);
ob_clean();
flush();
readfile($fullPath);
}
fclose ($fd);
}
exit;
?>
Here is the error i got in logs file of the server :
Warning: Cannot modify header information - headers already sent in (php file path)
I'm trying to download a simple text file from my server to the client in php. Unfortunately, when i try to download, a new white page appear and the download isn't ask to the user. But, if i refresh the page, the download is now ask and the user can accept to download the file like usual. Do anyone know why?
P.S. If anyone knows about how not opening another blank page to show the download and just show it on the page i clicked the link, any information would be appreciated.
Here is the code :
HTML
Download file
PHP
<?php
ignore_user_abort(true);
set_time_limit(0); // disable the time limit for this script
$path = "toDownload/"; // change the path to fit your websites document structure
$dl_file = $_GET['download_file']; // simple file name validation
$fullPath = $path.$dl_file;
if ($fd = fopen ($fullPath, "r"))
{
$fsize = filesize($fullPath);
$path_parts = pathinfo($fullPath);
$ext = strtolower($path_parts["extension"]);
switch ($ext)
{
case "txt":
header("Content-type: application/txt");
header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\""); // use 'attachment' to force a file download
break;
// add more headers for other content types here
default;
header("Content-type: application/octet-stream");
header("Content-Disposition: filename=\"".$path_parts["basename"]."\"");
break;
}
header("Content-length: $fsize");
header("Cache-control: public"); //use this to open files directly
while(!feof($fd))
{

I'm using PHP (PHPExcel) to handle all the excel files.
Currently I have saved a "New Template.xlsx" in a folder. And now I want the users to be able to download the "New Template.xlsx" at a click of a button.
How do i do that with php or phpexcel (i'm using Yii PHP framework as well)?
I'm not sure how to start, all I have now is
$filePath = Yii::app()->basePath . '\\vendors\\Excel Template\\New Template.xlsx';
Yii::import('application.vendors.PHPExcel', true);
$objPHPExcel = PHPExcel_IOFactory::load($filePath);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
Edit
Thanks to Miqi180's comments, I'm now able to download the excel file, however I am unable to open it because of invalid file extension/file format.
Here are my codes:
<?php
ignore_user_abort(true);
set_time_limit(0); // disable the time limit for this script
//$path = "/absolute_path_to_your_files/"; // change the path to fit your websites document structure
$path = Yii::app()->basePath . '\\vendors\\Excel Template\\';
//$dl_file = preg_replace("([^\w\s\d\-_~,;:\[\]\(\].]|[\.]{2,})", '', $_GET['download_file']); // simple file name validation
$dl_file = preg_replace("([^\w\s\d\-_~,;:\[\]\(\].]|[\.]{2,})", '', 'NewTemplate.xlsx'); // simple file name validation
$dl_file = filter_var($dl_file, FILTER_SANITIZE_URL); // Remove (more) invalid characters
$fullPath = $path.$dl_file;
if ($fd = fopen ($fullPath, "r")) {
$fsize = filesize($fullPath);
$path_parts = pathinfo($fullPath);
$ext = strtolower($path_parts["extension"]);
switch ($ext) {
case "xlsx":
//header("Content-type: application/vnd.ms-excel");
header("Content-type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\""); // use 'attachment' to force a file download
break;
// add more headers for other content types here
default;
header("Content-type: application/octet-stream");
header("Content-Disposition: filename=\"".$path_parts["basename"]."\"");
break;
}
header("Content-length: $fsize");
header("Cache-control: private"); //use this to open files directly
while(!feof($fd)) {
$buffer = fread($fd, 2048);
echo $buffer;
}
}
fclose ($fd);
exit;
Stop Yii from sending its own headers and output
Send the appropriate headers for an xlsx file
Save the file to php://output
Look at some of the examples in the PHPExcel Examples folder like 01simple-download-xlsx.php
But unless you're changing the template between loading it and sending it to the user, there's no need to use PHPExcel for this
Basically, what you need to do is execute a php script which fires when another page is loaded, e.g. "download.php" and then send the file through the header commands in that script.
Complete working code example taken from here:
<?php
ignore_user_abort(true);
set_time_limit(0); // disable the time limit for this script
$path = "/absolute_path_to_your_files/"; // change the path to fit your websites document structure
$dl_file = preg_replace("([^\w\s\d\-_~,;:\[\]\(\].]|[\.]{2,})", '', $_GET['download_file']); // simple file name validation
$dl_file = filter_var($dl_file, FILTER_SANITIZE_URL); // Remove (more) invalid characters
$fullPath = $path.$dl_file;
if ($fd = fopen ($fullPath, "r")) {
$fsize = filesize($fullPath);
$path_parts = pathinfo($fullPath);
$ext = strtolower($path_parts["extension"]);
switch ($ext) {
case "pdf":
header("Content-type: application/pdf");
header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\""); // use 'attachment' to force a file download
break;
// add more headers for other content types here
default;
header("Content-type: application/octet-stream");
header("Content-Disposition: filename=\"".$path_parts["basename"]."\"");
break;
}
header("Content-length: $fsize");
header("Cache-control: private"); //use this to open files directly
while(!feof($fd)) {
$buffer = fread($fd, 2048);
echo $buffer;
}
}
fclose ($fd);
exit;
However, you need to set the content-type correctly first (see this post).
from
header("Content-type: application/pdf");
to
header("Content-type: application/vnd.ms-excel");
or for For Excel2007 and above .xlsx files
header("Content-type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
Edit:
According to this MSDN blog article, the correct Extension MIME type for Excel .xlsx files actually is:
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
I'm currently using this code to hide download link but its giving uncompleted download for some users. I don't know why, but too many users report this problem to me.
My current code is:
file = "../".$realFileName;
$fakeFileName= 'Upbaz.ir-'.base64_decode($_GET['ffname']);
$fp = fopen($file, 'rb');
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=$fakeFileName");
header("Content-Length: " . filesize($file));
fpassthru($fp);
Anyone know other way to hide download link?
This script will handle the downloading of the file and it includes a buffer/ different ext types (if you desire). A good way to hide links is to put files in a protected directory and have links stored in a database. The user sees an ID or a session tied to a file and the server finds the file and serves it.
if ($fd = fopen ($fullPath, "r")) {
$fsize = filesize($fullPath);
$path_parts = pathinfo($fullPath);
$ext = strtolower($path_parts["extension"]);
switch ($ext) {
case "txt":
header("Content-type: application/txt"); // add here more headers for diff. extensions
header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\""); // use 'attachment' to force a download
break;
default:
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\"");
}
header("Content-length: $fsize");
header("Cache-control: private"); //use this to open files directly
while(!feof($fd)) {
$buffer = fread($fd, 2048);
echo $buffer;
}
}
fclose ($fd);
.htaccess to protect directory (you should have a dir for only these files
deny from all
Above script modified to yours:
$file = "../".$realFileName;
$fakeFileName= 'Upbaz.ir-'.base64_decode($_GET['ffname']);
if ($fd = fopen ($file, "r")) {
$fsize = filesize($file);
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$fakename\"");
header("Content-length: $fsize");
header("Cache-control: private"); //use this to open files directly
while(!feof($fd)) {
$buffer = fread($fd, 2048);
echo $buffer;
}
}
fclose ($fd);
