I am creating a zip file download system in php with jquery ajax.
When the user clicks the download button, the request goes to the server and returns the filename.
I am able to download the file but it shows the name of the entire file along with the file path in console. I do not want this.
<button onclick="checkPayment(this.id)" id="filetoDownload_1">Download File</button>
Javascript
function checkPayment(data){
$.ajax({
type: 'post',
url: '../download.php',
data: data,
async: false,
success: function(result) {
let returnkd = JSON.parse(result);
if(returnkd["status"]){
$("#success").html(`<div class="card"><div class="card-body bg-white text-black">Download will start soon...</div></div>`);
setTimeout(() => {
window.location.href = returnkd["filename"];
}, 2000);
}else{
$("#error").html(`<div class="card"><div class="card-body bg-white">Something wents wrong... contact admin</div></div>`);
}
}
});
}
PHP
// wothout header
if(isset($_POST)){
some code
return array("status"=>true,"filename"=>"../folder/filename.zip");
}
// with header
if(isset($_POST)){
some code here
downloadFile($filename);
return array("status"=>true,"filename"=>"../folder/filename.zip");
}
function downloadFile($filename)
{
$filename = $filename;
$filepath = "../".$filename;
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-type: application/octet-stream");
header('Content-Disposition: attachment; filename="' . $filename . '"');
header("Content-Transfer-Encoding: binary");
header("Content-Length: " . filesize($filepath));
ob_end_flush();
#readfile($filepath);
}
how to download file without redirecting window.location.href or showing filepath in console.

I am trying to get my php script to download an image which the name of is being sent in from an ajax function in my javascript, and I think I'm using all the right headers and then I'm using readfile() to download the image, and when I preview the php when it runs with the chrome developer tools (ctrl+shift+i-> network -> XHR -> preview) all I get is a bunch of gibberish binary and my image doesn't download. Does anyone know why this is happening/how to fix it?
Here's my ajax which is just in a function that runs when a "download" button is clicked
$.ajax({
type: "POST",
url: 'requestAJAX.php',
data: {request: request, download: imageName},
success: function(){
console.log("Request Completed: " + request);
} // success
});
and here's my "requestAJAX.php"
<?php
switch ($_POST["request"]) {
case "download":
// Get parameters
$file = $_POST["download"];
$filepath = "UploadedImages/" . $file;
if(file_exists($filepath)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.$file.'"');
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($filepath));
ob_clean();
flush();
// download
readfile($filepath);
exit;
} // if
break;
default:
echo "No request was made";
}
?>
and this is what I'm getting when I preview (not sure how it will help)

I am trying to download a pdf when clicking on a link.
I called function onlick of a link and in Codeigniter i wrote a function to download PDF file but when running URL ,file is downloaded but when triggered using click of link, its not working.
Controller:
function downloadpdf($pid)
{ set_time_limit(0);
$url="http://www.malayatourism.com/uploads/images/packages/pdf/$pid.pdf";
$file = basename($url);
$fp = fopen($file, 'w');
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_FILE, $fp);
$data = curl_exec($ch);
curl_close($ch);
fclose($fp);
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));
ob_clean();
flush();
readfile($file);
echo "success";
}
My code ajax:
function DownLoadPdf(id)
{
url = "<?php echo base_url();?>admin/packages/downloadpdf/"+id;
$.ajax({
type:'POST',
url: url,
data : { pid : id},
success : function(response) {
console.log(response);
},
error : function(response) {
console.log("error");
}
});
}
View:
echo ' Download Attachment';
As far as ajax is concerned you cannot do that via ajax because ajax is not made for this purpose,its an asynchronous call that will give you a result. But you can do this without using any jquery, ajax at all
<a href="http://www.malayatourism.com/uploads/images/packages/pdf/$pid.pdf" download> Download Attachment</a>
Where $pid is the id you want to download the file. The download attribute will force the file to download. Cheers
I have one PHP file and other JavaScript. In JavaScript, I pass the variable with location of place where the file exists but on the PHP side doesn't recognize and doesn't properly download the file.
Code of JavaScript:
var nameFile = oEvent.getParameters().listItem.getTitle();
var directory = "C:/xampp/htdocsui5launchpad/WebContent/documents/";
window.location =directory;
$.ajax({
url: 'http://localhost/ui5launchpad/WebContent/php/downloadPDF.php',
type: 'POST',
datatype: "json",
data: { album: nameFile },
success: function (response, data, xhr) {
window.location = 'http://localhost/ui5launchpad/WebContent/php/downloadPDF.php';
},
error: function (response) {
console.log("Error in PHP, downloadPDF.php ");
}
});
PHP code:
if(isset($_POST["album"])){
$name = $_POST["album"];
}
$dir = "C:/xampp/htdocs/ui5launchpad/WebContent/documents/";
$file = $dir . $name;
if( isset($file)) {
//echo $file;
if (file_exists($file)) {
//echo $file;
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
}
Can you help me, please ?
Thanks
You don't need to use ajax to download a file. Just link the file direct to the browser.
In the link tag put the attribute like this:
<a href="http://example.com/file.pdf" download>Download</a>
i am this problem of not being able to download image from server to my PC(No saving prompt ) , no error message have been shown
The output i am receiving is some unreadable code from the google chrome inspect element
Thanks in advance
Javascript
function Download(id) {
console.log(id);
$.ajax({
type: 'post',
url: 'DownloadRequest.php',
data: {filename: id.trim()},
});
}
DownloadRequest.php File
<?php
$file = $_POST['filename'];
header ("Content-Type: application/download");
header ("Content-Disposition: attachment; filename=$file");
header("Content-Length: " . filesize("$file"));
$fp = fopen("$file", "r");
fpassthru($fp);
?>
Solution
function Download(id) {
window.location="DownloadRequest.php?url="+id.trim();
}
<?php
$file = $_GET['url'];;
header ("Content-Type: application/download");
header ("Content-Disposition: attachment; filename=$file");
header("Content-Length: " . filesize("$file"));
$fp = fopen("$file", "r");
fpassthru($fp);
?>
you can try like this, instead of using ajax,
window.location="DownloadRequest.php?filename";
Final code,
function Download(id) {
console.log(id);
window.location="DownloadRequest.php?filename";
}
I am trying to send files to the client via jQuery, AJAX, and PHP. I am using jQuery v1.11.2 and xampp v3.2.1,
Here is my jQuery code:
<script>
$(document).ready(function(){
$("#myBtn").click(function(){
$.ajax({ // post file name
type: "POST",
data: {
file: "testfile.xlsx"
},
url: "sendfile.php",
context: $("#result"),
success: function(data, status, xhr){
$(this).html(data);
}
});
});
});
</script>
sendfile.php:
<?php
FUNCTION send_file($name) { // function ... send file to client
OB_END_CLEAN();
$path = $name;
//cek connection if lost connection with client
IF (!IS_FILE($path) or CONNECTION_STATUS()!=0) RETURN(FALSE);
//header
//-------------------------------------------------------------
HEADER("Cache-Control: no-store, no-cache, must-revalidate");
HEADER("Cache-Control: post-check=0, pre-check=0", FALSE);
HEADER("Pragma: no-cache");
HEADER("Expires: ".GMDATE("D, d M Y H:i:s", MKTIME(DATE("H")+2, DATE("i"), DATE("s"), DATE("m"), DATE("d"), DATE("Y")))." GMT");
//set last modified property
HEADER("Last-Modified: ".GMDATE("D, d M Y H:i:s")." GMT");
HEADER("Content-Type: application/octet-stream");
HEADER("Content-Length: ".(string)(FILESIZE($path)));
HEADER("Content-Disposition: inline; filename=$name"); // file
HEADER("Content-Transfer-Encoding: binary\n");
//-----------------------------------------------------------------
IF ($file = FOPEN($path, 'rb')) { // send file
WHILE(!FEOF($file) and (CONNECTION_STATUS()==0)) {
PRINT(FREAD($file, 1024*8));
FLUSH();
}
FCLOSE($file);
}
RETURN((CONNECTION_STATUS()==0) and !CONNECTION_ABORTED());
}
// send file
if(!send_file($_POST['file'])){
echo "error.";
}
When I press the button no files received instead of random sentences in #result
If I use directly in PHP functions are working properly
send_file("testfile.xlsx");
Are there more effective methods?
