download file as unknown file in laravel - laravel

I want to download a pdf file from storage
public function show($free)
{
$dl = SingleFreeDownload::find($free);
return Storage::download($dl->file , $dl->title);
}
and this is the file storage code:
public function store(Request $request)
{
$file = $request->file('file')->store('uploads');
$single_download_page=[
'file' => $file, ];
SingleFreeDownload::create($single_download_page);
}
when I click on download button it downloads unknown file and it not open what is the problem?

First I wouldn't call the method which shall download a file show() I would rename it to download. Second I would check whether the file exists or not if it exists I would try to download it.
You can check whether it exists or not using this:
$exists = Storage::exists('myfile.jpg');
if ($exists) {
return Storage::download($dl->file , $dl->title);
}
Furthermore you should check wether your input contains the name file since you are doing this:
$file = $request->file('file')->store('uploads');
Your input needs to look like this:
<input name="file"...>
You should also show what this class does SingleFreeDownload.

I am trying to upload a file and save the file path to my database so as to be able to access it

I am trying to save file paths to a database and move the files to a given directory. The file path gets save to the database but the files don't get uploaded. Please help
I tried to specify the file path and rename the file
Here is my controller:
public function uploadId(Request $request)
{
$pathOne = $request->file('front_id')->move('public/verify/', 'front_id'.time());
$pathTwo = $request->file('back_id')->move('images/verify/', 'back_id'.time());
$pathThree = $request->file('address')->move('images/verify/', 'address'.time());
$identification = new Identification;
$identification->user_id = Auth::user()->id;
$identification->front_id = $pathOne;
$identification->back_id = $pathTwo;
$identification->address = $pathThree;
$identification->save();
return redirect()->back()->with("success", "Your ID's has successfully been uploaded.");
}
I expect that the file gets saved to the database and uploaded to the directory but that's not the case. The file path only gets saved.
You aren't storing the files anywhere in your code. You can't move a file that hasn't been saved yet.
$path = $request->file('avatar')->store('avatars');

Laravel : To rename an uploaded file automatically

I am allowing users to upload any kind of file on my page, but there might be a clash in names of files. So, I want to rename the file automatically, so that anytime any file gets uploaded, in the database and in the folder after upload, the name of the file gets changed also when other user downloads the same file, renamed file will get downloaded.
I tried:
if (Input::hasFile('file')){
echo "Uploaded</br>";
$file = Input::file('file');
$file ->move('uploads');
$fileName = Input::get('rename_to');
}
But, the name gets changed to something like:
php5DEB.php
phpCFEC.php
What can I do to maintain the file in the same type and format and just change its name?
I also want to know how can I show the recently uploaded file on the page and make other users download it??
For unique file Name saving
In 5.3 (best for me because use md5_file hashname in Illuminate\Http\UploadedFile):
public function saveFile(Request $request) {
$file = $request->file('your_input_name')->store('your_path','your_disk');
}
In 5.4 (use not unique Str::random(40) hashname in Illuminate\Http\UploadedFile). I Use this code to ensure unique name:
public function saveFile(Request $request) {
$md5Name = md5_file($request->file('your_input_name')->getRealPath());
$guessExtension = $request->file('your_input_name')->guessExtension();
$file = $request->file('your_input_name')->storeAs('your_path', $md5Name.'.'.$guessExtension ,'your_disk');
}
Use this one
$file->move($destinationPath, $fileName);
You can use php core function rename(oldname,newName) http://php.net/manual/en/function.rename.php

file uploads 101
Everything you need to know about file upload is there.
-- Edit --
I modified my answer as below after valuable input from #cpburnz and #Moinuddin Quadri. Thanks guys.
First your storage driver should look like this in /your-app/config/filesystems.php
'public' => [
'driver' => 'local',
'root' => storage_path('app/public'), // hence /your-app/storage/app/public
'visibility' => 'public',
],
You can use other file drivers like s3 but for my example I'm working on local driver.
In your Controller you do the following.
$file = request()->file('file'); // Get the file from request
$yourModel->create([
'file' => $file->store('my_files', 'public'),
]);
Your file get uploaded to /your-app/storage/app/public/my_files/ and you can access the uploaded file like
asset('storage/'.$yourModel->image)
Make sure you do
php artisan storage:link
to generate a simlink in your /your-app/public/ that points to /your-app/storage/app/public so you could access your files publicly. More info on filesystem - the public disk.
By this approach you could persists the same file name as that is uploaded. And the great thing is Laravel generates an unique name for the file so there could be no duplicates.
To answer the second part of your question that is to show recently uploaded files, as you persist a reference for the file in the database, you could access them by your database record and make it ->orderBy('id', 'DESC');. You could use whatever your logic is and order by descending order.
You can rename your uploaded file as you want . you can use either move or storeAs method with appropiate param.
$destinationPath = 'uploads';
$file = $request->file('product_image');
foreach($file as $singleFile){
$original_name = strtolower(trim($singleFile->getClientOriginalName()));
$file_name = time().rand(100,999).$original_name;
// use one of following
// $singleFile->move($destinationPath,$file_name); public folder
// $singleFile->storeAs('product',$file_name); storage folder
$fileArray[] = $file_name;
}
print_r($fileArray);
correct usage.
$fileName = Input::get('rename_to');
Input::file('photo')->move($destinationPath, $fileName);
at the top after namespace
use Storage;
Just do something like this ....
// read files
$excel = $request->file('file');
// rename file
$excelName = time().$excel->getClientOriginalName();
// rename to anything
$excelName = substr($excelName, strpos($excelName, '.c'));
$excelName = 'Catss_NSE_'.date("M_D_Y_h:i_a_").$excelName;
$excel->move(public_path('equities'),$excelName);
This guy collect the extension only:
$excelName = substr($excelName, strpos($excelName, '.c'));
This guy rename its:
$excelName = 'Catss_NSE_'.date("M_D_Y_h:i_a_").$excelName;

Laravel 5.3 import CSV from file without uploading

I am using Maatwebsite/Excel to import CSV files. My code looks like this tutorial: http://itsolutionstuff.com/post/laravel-5-import-export-to-excel-and-csv-using-maatwebsite-exampleexample.html
I marged both functions and my script gets file and returns file/
But despite many attempts I can't skip uploading file. It means, that I have CSV file in special folder, and I would like to get this file to process data, without uploading. It will automatically get file (maybe file_get_contents ?), and pass it to Illuminate\Support\Facades\Input.
This is the perfect way to import your csv in laravel 5.*
public function importExcel() {
if (Input::hasFile('import_file')) {
$path = Input::file('import_file')->getRealPath();
$data = Excel::load($path, function($reader) {
})->get();
if (!empty($data) && $data->count()) {
$count = 0;
foreach ($data as $key => $d) {
$insert = array();
$insert['name'] = $value->name;
$this->user->create($insert);
}
}
}
}
You can read your excel file using this code
// for sheet 1
$excelData = $excel->selectSheetsByIndex(0)->load($yourFilePath)->get();
print_r($excelData);
I found solution. We can skip if (Input::hasFile('import_file')) { and $path variable set to our CSV file path

How to display file which had already upload laravel 5.2?

I upload file in to my database and moved that file as same name in documents folder in a root path like below :)
public function store(PslCall $call,Request $request)
{
$this->validate($request, $this->rules);
$uploadDestinationPath = base_path() . '/documents/';
$current_id = Document::where('call_id',$call->id)->count()+1;
if ($request->hasFile('file'))
{
$file =$request->file;
$fileName = $file->getClientOriginalName();
$file->move($uploadDestinationPath, $call->id.'_'.$current_id.'_'.$fileName);
}
$input = $request->all();
$input['file'] = $call->id.'_'.$current_id.'_'.$fileName;
$input['call_id'] = $call->id;
Auth::user()->documents()->create($input);
return Redirect::route('calls.documents.index',$call->id)->with('message','You have successfully submitted');
}
its works perfect now im display in my index page all the files like below :)
<td>{{strtoupper($document->title)}}</td>
<td>{{$document->file}}</td>
now my route file i have route to display my file like this :
Route::get('documents/{file}',function() {
return 'hi';
});
here im getting hi output when i click <td>{{$document->file}}</td> this path
but i want know how to display file which i upload same file name ?
As documentation says if you want to display the file content then you may use inside your route function something like:
return response()->file('pathToFile');
If download the file is what you want, then try to use instead:
return response()->download('pathToFile');

How to protect image from public view in Laravel 5?

I have installed Laravel 5.0 and have made Authentication. Everything is working just fine.
My web site is only open for Authenticated members. The content inside is protected to Authenticated members only, but the images inside the site is not protected for public view.
Any one writes the image URL directly can see the image, even if the person is not logged in to the system.
http://www.somedomainname.net/images/users/userImage.jpg
My Question: is it possible to protect images (the above URL example) from public view, in other Word if a URL of the image send to any person, the individual must be member and login to be able to see the image.
Is that possible and how?
It is possible to protect images from public view in Laravel 5.x folder.
Create images folder under storage folder (I have chosen storage folder because it has write permission already that I can use when I upload images to it) in Laravel like storage/app/images.
Move the images you want to protect from public folder to the new created images folder. You could also chose other location to create images folder but not inside the public folder, but with in Laravel folder structure but still a logical location example not inside controller folder. Next you need to create a route and image controller.
Create Route
Route::get('images/users/{user_id}/{slug}', [
'as' => 'images.show',
'uses' => 'ImagesController#show',
'middleware' => 'auth',
]);
The route will forward all image request access to Authentication page if person is not logged in.
Create ImagesController
class ImagesController extends Controller {
public function show($user_id, $slug)
{
$storagePath = storage_path('app/images/users/' . $user_id . '/' . $slug);
return Image::make($storagePath)->response();
}
}
EDIT (NOTE)
For those who use Laravel 5.2 and newer. Laravel introduces new and better way to serve files that has less overhead (This way does not regenerate the file as mentioned in the answer):
File Responses
The file method can be used to display a file, such as an image or
PDF, directly in the user's browser instead of initiating a download.
This method accepts the path to the file as its first argument and an
array of headers as its second argument:
return response()->file($pathToFile);
return response()->file($pathToFile, $headers);
You can modify your storage path and file/folder structure as you wish to fit your requirement, this is just to demonstrate how I did it and how it works.
You can also added condition to show the images only for specific members in the controller.
It is also possible to hash the file name with file name, time stamp and other variables in addition.
Addition: some asked if this method can be used as alternative to public folder upload, YES it is possible but it is not recommended practice as explained in this answer. So the same method can be also used to upload images in storage path even if you do not intend to protect them, just follow the same process but remove 'middleware' => 'auth',. That way you won't give 777 permission in your public folder and still have a safe uploading environment. The same mentioned answer also explain how to use this method with out authentication in case some one would use it or giving alternative solution as well.
In a previous project I protected the uploads by doing the following:
Created Storage Disk:
config/filesystems.php
'myDisk' => [
'driver' => 'local',
'root' => storage_path('app/uploads'),
'url' => env('APP_URL') . '/storage',
'visibility' => 'private',
],
This will upload the files to \storage\app\uploads\ which is not available to public viewing.
To save files on your controller:
Storage::disk('myDisk')->put('/ANY FOLDER NAME/' . $file, $data);
In order for users to view the files and to protect the uploads from unauthorized access. First check if the file exist on the disk:
public function returnFile($file)
{
//This method will look for the file and get it from drive
$path = storage_path('app/uploads/ANY FOLDER NAME/' . $file);
try {
$file = File::get($path);
$type = File::mimeType($path);
$response = Response::make($file, 200);
$response->header("Content-Type", $type);
return $response;
} catch (FileNotFoundException $exception) {
abort(404);
}
}
Serve the file if the user have the right access:
public function licenceFileShow($file)
{
/**
*Make sure the #param $file has a dot
* Then check if the user has Admin Role. If true serve else
*/
if (strpos($file, '.') !== false) {
if (Auth::user()->hasAnyRole(['Admin'])) {
/** Serve the file for the Admin*/
return $this->returnFile($file);
} else {
/**Logic to check if the request is from file owner**/
return $this->returnFile($file);
}
} else {
//Invalid file name given
return redirect()->route('home');
}
}
Finally on Web.php routes:
Route::get('uploads/user-files/{filename}', 'MiscController#licenceFileShow');
I haven't actually tried this but I found Nginx auth_request module that allows you to check the authentication from Laravel, but still send the file using Nginx.
It sends an internal request to given url and checks the http code for success (2xx) or failure (4xx) and on success, lets the user download the file.
Edit: Another option is something I've tried and it seemed to work fine. You can use X-Accel-Redirect -header to serve the file from Nginx. The request goes through PHP, but instead of sending the whole file through, it just sends the file location to Nginx which then serves it to the client.
if I am understanding you it's like !
Route::post('/download/{id}', function(Request $request , $id){
{
if(\Auth::user()->id == $id) {
return \Storage::download($request->f);
}
else {
\Session::flash('error' , 'Access deny');
return back();
}
}
})->name('download')->middleware('auth:owner,admin,web');
Every file inside the public folder is accessible in the browser. Anyone easily gets that file if they find out the file name and storage path.
So better option is to store the file outside the public folder eg: /storage/app/private
Now do following steps:
create a route (eg: private/{file_name})
Route::get('/private/{file_name}', [App\Http\Controllers\FileController::class, 'view'])->middleware(['auth'])->name('view.file');
create a function in a controller that returns a file path. to create a controller run the command php artisan make:controller FileController
and paste the view function in FileController
public function view($file)
{
$filePath = "notes/{$file}";
if(Storage::exists($filePath)){
return Storage::response($filePath);
}
abort(404);
}
then, paste use Illuminate\Support\Facades\Storage; in FileController for Storage
And don't forget to assign middleware (in route or controller) as your requirement(eg: auth)
And now, only those who have access to that middleware can access that file through a route name called view.file
