Display image from laravel controller - php

Would like to ask if anyone has ever tried to display an image from a Laravel Controller. Below is my code to a Laravel Controller. So basically I just want to hide the actual url of image and add additional validation so I decided to the image call my laravel URL.
Blade code that call the laravel controller
<img src="/image/1">
Route
Route::get('/image/{image_id}', ['as' => 'site.viewImage', 'uses' => 'ImageController#viewImage']);
Controller
public function viewImage($image_id)
{
return Storage::get($image_id . '.png');
}
But this return an error not-found. Am I doing something wrong here?
Note: I'm passing it to the controller because I need to do additional valdiation and to obfuscate the actual url of the file
I tried this code and its working but I would like a laravel type of approach
header("Content-type: image/png");
echo Storage::get($image_id .'.png');exit;
I also tried this approach
$response = response()->make(Storage::get($image_id . '.png'), 200);
$response->header("Content-Type", 'image/png');
return $response;
The laravel approach throws a 404 error.

Have you tried
return response()->file($filePath);
See: https://laravel.com/docs/5.3/responses#file-responses

If you want to show file from public folder
$link=url('link/to/image/'.$imageName);
header("Content-type: image/png");
$imageContent = file_get_contents($link);
echo $imageContent;
die();

Old question but you can do something like this in Laravel 9.x.
Blade:
<img src="/image/1">
Route:
Route::get('/image/{id}', [ImageController::class, 'viewImage']);
Controller:
public function viewImage($id)
{
// $image_path would look something like this: './images/abc.png'
$image_path = $id.'.png';
return response()->file( $image_path );
}

Laravel: Refresh response()->file

In Laravel I use this route
Route::get('admin/showBill/{file}','Admin\FileController#showBill');
and this code
class FileController extends AuthController
{
public function showBill($file)
{
$path = storage_path('app/bills/' . basename($file) );
if(!\File::exists($path)) return back();
return response()->file($path);
}
to display a pdf from my storage folder.
So if I have the pdf bill-1.pdf in my /storage/app/bills/ folder, then I can view it with the url
example-domain.com/admin/showBill/bill-1.pdf
The problem is that if I open that pdf with the browser, replace it, and refresh (F5) the page, then the old bill is shown. I guess its because its stored in the cache. Can I force Laravel to show the new replaced file?
I tried
public function showBill($file)
{
$path = storage_path('app/bills/' . basename($file) );
if(!\File::exists($path)) return back();
$path .= '?v='. time();
return response()->file($path);
}
But then Laravel tells me that this file does not exist. I am looking for a solution where I have not to rename the pdf file.
Are you sure you're replacing the right file?
If so, place this dd(). I've created an endpoint, response an empty pdf file - viewed it - replaced it with a content-filled pdf file and it works just fine when I replace it.
Edit: Also, you should validate the $file variable, using either a formrequest or validating in the controller.
public function showBill($file)
{
$path = storage_path('app/bills/' . basename($file));
if(!\File::exists($path)) {
dd("Quite possibly the problem is here, on the redirect back");
}
return response()->file($path);
}

How to hide directory while giving directory Link?

I have build a laravel application where I have some files on public/files directory. if I give this link to others such as download Link, they have chance to know my directory ..
Suppose the link i have to give download link as
www.abc.com/files/45454553535.zip
But i don't want to let Users know that it's there in files directory. So How Do i hide the directory?
Keep your files in the storage directory. That way you can serve the file to the users through code.
Try to follow the documentation: https://laravel.com/docs/5.4/filesystem
I don't know whether this would work or not but giving you an idea. Create a php file use like this:
header('Content-Type: application/zip');
$a=file_get_contents(file.zip)
echo $a;
From this user will not know from where the contents are fetched.
Try this.
public function getDownload()
{
$filename='45454553535.zip'
$file= public_path(). "/files/".$filename;
$headers = array(
'Content-Type: application/zip',
);
return Response::download($file, $filename, $headers);
}
".files/45454553535.zip"will not work as you have to give full physical path.
Update 20/05/2016
Laravel 5, 5.1, 5.2 or 5.* users can use the following method instead of Response facade. However, my previous answer will work for both Laravel 4 or 5.
return response()->download($file, $filename, $headers);
You can just create a your controller and route.
Route::get('files/{filename}', [
'as' => 'file.get',
'uses' => 'FileController#get',
]);
Controller should check your proper directory. Try to keep your files in storage path, not public.
class FileController extends Controller
{
private $path;
public function __construct()
{
$path = storage_path()
. '/your-valid-directory/';
}
public function get($filename)
{
$file_path = $this->path
. filter_var($filename, FILTER_SANITIZE_STRING);
if (file_exists($file_path) && is_readable($file_path)) {
return response(file_get_contents($file_path), 200, [
'Content-Type: application/zip',
]);
} else {
abort(404);
}
}
}
Now you can get access to specific file by:
{{ route('file.get', ['filename' => '45454553535.zip') }}
This action generate link looks like: your-domain.com/files/45454553535.zip. :)
Anyway in my opinion - in the future just make file factory with specific headers, directories.
Good luck!

How to display image from aws s3 in blade laravel 5.2

I have created a method for getting the data(image file) from aws S3 like this :
public static function getImage ($imagePath)
{
if(Storage::exists($imagePath))
{
return Storage::disk('s3')->get($imagePath);
}else
{
return 'No Image';
}
}
I'm sure that those image is exist on the aws, so there is no problem with that.
And then I use above method as the src in my blade view like this :
{!!Html::image(getImage($myPath),'logo',['width'=>60,'height'=>55])!!}
$myPath here already point to the specific file on aws for example : bucket/file.jgp. But when I run my webpage, this Html::Image gives a view like this :
What's going on here ? Why Html::image can't render my image file ? :(
Works on Laravel 6.x
<img src="{{Storage::disk('s3')->url($imagePath)}}">
You can use Storage::url($imagePath). Please see Filesystem / Cloud storage on laravel docs
{!!Html::image(<Your S3 bucket URL>.$myPath),'logo',['width'=>60,'height'=>55])!!}
You can save the S3 URL in a config file and use the config value instead of writing actual value everytime.
I had the same issue. This code snippet solved it
<img src="{!! url(<path to your image>) !!}" />
First, you need to give it public promotion in the controller
$path = Storage::disk('s3')->put('profileImages/', $request->file('profile_image'), 'public');
//save image name in database
$user->profile_image = basename($path);
In blade file
<img src="{{Storage::disk('s3')->url('profileImages/' . $user->profile_image)}}" />
You can add an accessor like follow to get Image URL
It returns URL to the image and you can access it by $profile->image
public function getImageAttribute($value)
{
if ($value) {
return Storage::disk('s3')->url($value);
}
return "https://source.unsplash.com/96x96/daily";
}
I assume you save image as follow
$path = $request->file('image')->store('images', 's3');
Storage::disk('s3')->setVisibility($path, 'public');
$profile->update([
'image' => $path
]);
You can check this commit for more detail
https://github.com/itxshakil/ediary/commit/23cb4b1cb7b8a4eac68f534e8c5b6897abc6421a
I have read every solution and no one has pointed it directly. So I thought to write my answers. For this problem I just required to add this simple line and boom, it starts working. But I got access denied alert you should check that problem too.
<img class="img-responsive" src="{!! Storage::disk('s3')->url('thumbs/' . $business->image->path) !!}" alt="thumb">
This works
Storage::disk('s3')->url($imagePath)
and also from your Minio Browser.
You have to Add a policy to Read and Write
I think that private visibility of images is an important security feature.
I found a solution :-)
Method in Controller:
/**
* #param string $name : image name on bucket
* ( stored if you want into database )
*/
public function show( $name ) {
$path = config('filesystems.disks.s3.base_directory') . '/' . $name;
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = Storage::get( $path );
$base64 = 'data:image/' . $type . ';base64,' . base64_encode( $data );
return view( 'show', [ 'src' => $base64 ]);
}
The view:
...
<div class="panel panel-primary">
<div class="panel-heading"><h2>Laravel File Retrive with Amazon S3 </h2></div>
<div class="panel-body">
**<img src="{{ $src }}"/>**
</div>
</div>
...

Laravel empty page with no error calling route's method

I have a methods that return base64 data image to a view after making a GET request to www.website.com/preview/{id}.
It is called by an <a> tag inside view.blade.php:
<a class="image-popup-vertical-fit" href="{{url(Config::get("app.previewPath") , $encrypted)}}" >
<img class="issue_img" src="{{App\Http\Classes\RepositoryUtil::getSmallImage($encrypted)}}" alt="{{ $name }}">
</a>
It work well if I declare a GET route with the code function inside routes.php:
Route::get(Config::get("app.previewPath") . "/{id}", function(\Request $request, $encrypted){
// ... some code ...
$base64 = \App\Http\Classes\RepositoryUtil::retriveImage($encrypted);
#readfile($base64);
});
But if I move the same code inside a controller's method, it return a blank page!
Route::get(Config::get("app.previewPath") . "/{id}", "MyController#getPreview");
MyController.php
public static function getPreview(\Request $request, $encrypted){
// ... same code as routes.php ...
$base64 = \App\Http\Classes\RepositoryUtil::retriveImage($encrypted);
#readfile($base64);
}
Where am I wrong?
I figure it out, it was a "distraction error".
I leave a middleware enabled in all methods of the controller, and it fails printing dd("Not authorized!"); without return before it.
It didn't return nothing without any errors!
I restrincted the middleware only to selected actions.
Thanks for support.

Download files in laravel using Response::download

In Laravel application I'm trying to achieve a button inside view that can allow user to download file without navigating to any other view or route
Now I have two issues:
(1) below function throwing
The file "/public/download/info.pdf" does not exist
(2) Download button should not navigate user to anywhere and rather just download files on a same view, My current settings, routing a view to '/download'
Here is how Im trying to achieve:
Button:
<i class="icon-download-alt"> </i> Download Brochure
Route :
Route::get('/download', 'HomeController#getDownload');
Controller :
public function getDownload(){
//PDF file is stored under project/public/download/info.pdf
$file="./download/info.pdf";
return Response::download($file);
}
Try this.
public function getDownload()
{
//PDF file is stored under project/public/download/info.pdf
$file= public_path(). "/download/info.pdf";
$headers = array(
'Content-Type: application/pdf',
);
return Response::download($file, 'filename.pdf', $headers);
}
"./download/info.pdf"will not work as you have to give full physical path.
Update 20/05/2016
Laravel 5, 5.1, 5.2 or 5.* users can use the following method instead of Response facade. However, my previous answer will work for both Laravel 4 or 5. (the $header array structure change to associative array =>- the colon after 'Content-Type' was deleted - if we don't do those changes then headers will be added in wrong way: the name of header wil be number started from 0,1,...)
$headers = [
'Content-Type' => 'application/pdf',
];
return response()->download($file, 'filename.pdf', $headers);
File downloads are super simple in Laravel 5.
As #Ashwani mentioned Laravel 5 allows file downloads with response()->download() to return file for download. We no longer need to mess with any headers. To return a file we simply:
return response()->download(public_path('file_path/from_public_dir.pdf'));
from within the controller.
Reusable Download Route/Controller
Now let's make a reusable file download route and controller so we can server up any file in our public/files directory.
Create the controller:
php artisan make:controller --plain DownloadsController
Create the route in app/Http/routes.php:
Route::get('/download/{file}', 'DownloadsController#download');
Make download method in app/Http/Controllers/DownloadsController:
class DownloadsController extends Controller
{
public function download($file_name) {
$file_path = public_path('files/'.$file_name);
return response()->download($file_path);
}
}
Now simply drops some files in the public/files directory and you can server them up by linking to /download/filename.ext:
File Name // update to your own "filename.ext"
If you pulled in Laravel Collective's Html package you can use the Html facade:
{!! Html::link('download/filename.ext', 'File Name') !!}
In the accepted answer, for Laravel 4 the headers array is constructed incorrectly. Use:
$headers = array(
'Content-Type' => 'application/pdf',
);
Quite a few of these solutions suggest referencing the public_path() of the Laravel application in order to locate the file. Sometimes you'll want to control access to the file or offer real-time monitoring of the file. In this case, you'll want to keep the directory private and limit access by a method in a controller class. The following method should help with this:
public function show(Request $request, File $file) {
// Perform validation/authentication/auditing logic on the request
// Fire off any events or notifiations (if applicable)
return response()->download(storage_path('app/' . $file->location));
}
There are other paths that you could use as well, described on
Laravel's helper functions documentation
While using laravel 5 use this code as you don`t need headers.
return response()->download($pathToFile); .
If you are using Fileentry you can use below function for downloading.
// download file
public function download($fileId){
$entry = Fileentry::where('file_id', '=', $fileId)->firstOrFail();
$pathToFile=storage_path()."/app/".$entry->filename;
return response()->download($pathToFile);
}
HTML href link click:
<a ="{{ route('download',$name->file) }}"> Download </a>
In controller:
public function download($file){
$file_path = public_path('uploads/cv/'.$file);
return response()->download( $file_path);
}
In route:
Route::get('/download/{file}','Controller#download')->name('download');
I think that you can use
$file= public_path(). "/download/info.pdf";
$headers = array(
'Content-Type: ' . mime_content_type( $file ),
);
With this you be sure that is a pdf.
// Try this to download any file. laravel 5.*
// you need to use facade "use Illuminate\Http\Response;"
public function getDownload()
{
//PDF file is stored under project/public/download/info.pdf
$file= public_path(). "/download/info.pdf";
return response()->download($file);
}
HTML link click
<a class="download" href="{{route('project.download',$post->id)}}">DOWNLOAD</a>
// Route
Route::group(['middleware'=>['auth']], function(){
Route::get('file-download/{id}', 'PostController#downloadproject')->name('project.download');
});
public function downloadproject($id) {
$book_cover = Post::where('id', $id)->firstOrFail();
$path = public_path(). '/storage/uploads/zip/'. $book_cover->zip;
return response()->download($path, $book_cover
->original_filename, ['Content-Type' => $book_cover->mime]);
}
This is html part
<a href="{{route('download',$details->report_id)}}" type="button" class="btn btn-primary download" data-report_id="{{$details->report_id}}" >Download</a>
This is Route :
Route::get('/download/{id}', 'users\UserController#getDownload')->name('download')->middleware('auth');
This is function :
public function getDownload(Request $request,$id)
{
$file= public_path(). "/pdf/"; //path of your directory
$headers = array(
'Content-Type: application/pdf',
);
return Response::download($file.$pdfName, 'filename.pdf', $headers);
}
you can use simply inside your controller:
return response()->download($filePath);
Happy coding :)
If you want to use the JavaScript download functionality then you can also do
<a onclick="window.open('info.pdf) class="btn btn-large pull-right"><i class="icon-download-alt"> </i> Download Brochure </a>
Also remember to paste the info.pdf file in your public directory of your project
