Question

I am trying to zip some images as user-selected.up to now I have come up with a solution for zipping.My problem is after I zip the relevant data to zip file how can I download it through the browser.i have tried different methods still not working.when I create zip it stored in the public folder.how can I download the zip file from there through the browser?
Here is my code
$photos = json_decode(Input::get('photos'));
$dir = time();
foreach ($photos as $file) {
/* Log::error(ImageHandler::getUploadPath(false, $file));*/
$imgName = last(explode('/', $file));
$path = public_path('downloads/' . $dir);
if (!File::exists($path)) {
File::makeDirectory($path, 0775, true);
}
ImageHandler::downloadFile($file, $path . '/' . $imgName);
}
$rootPath = realpath($path);
$zip_file = 'Photos.zip';
$public_dir = public_path();
$zip = new ZipArchive();
$zip->open($zip_file, ZipArchive::CREATE | ZipArchive::OVERWRITE);
/** #var SplFileInfo[] $files */
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($rootPath),
RecursiveIteratorIterator::LEAVES_ONLY
);
foreach ($files as $name => $file1) {
// Skip directories (they would be added automatically)
if (!$file1->isDir()) {
// Get real and relative path for current file
$filePath = $file1->getRealPath();
$relativePath = substr($filePath, strlen($rootPath) + 1);
// Add current file to archive
$zip->addFile($filePath, $relativePath);
}
}
// Zip archive will be created only after closing object
$zip->close();
$fileurl = public_path()."/Photos.zip";
if (file_exists($fileurl))
{
return Response::download($fileurl, 'Photos.zip', ['Content-Length: '. filesize($fileurl)]);
} else {
exit('Requested file does not exist on our server!');
}
In response i'm getting something like this:

The problem is you're trying to load the file via AJAX, which you can't do the way that you're trying to do it.
if (file_exists($fileurl)) {
return Response::download($fileurl, 'Photos.zip', array('Content-Type: application/octet-stream','Content-Length: '. filesize($fileurl)))->deleteFileAfterSend(true);
} else {
return ['status'=>'zip file does not exist'];
}
Change your javascript to:
let xhr = new XMLHttpRequest(), self = this;
window.location = window.location.origin+'/download-file/' + this.selected
Hope this helps you!

Try changing
return Response::download($fileurl, 'Photos.zip', ['Content-Length: '. filesize($fileurl)]);
to
return Response::download($fileurl, 'Photos.zip', array('Content-Type: application/zip','Content-Length: '. filesize($fileurl)));
OR
return Response::download($fileurl, 'Photos.zip', array('Content-Type: application/octet-stream','Content-Length: '. filesize($fileurl)));

try this way may be it help. just return you zip file and path name in ajax success
in controller
$fileurl = public_path()."/Photos.zip";
if (file_exists($fileurl))
{
return response()->json($fileurl);
}
else
{
exit('Requested file does not exist on our server!');
}
then add this line
success: function (data) {
'download': data.fileurl,
}
