Laravel fail to return image - php

I've a image and some text file in storage folder other than the public folder. the folder architecture is
storage
|->uploads
and set a route like
Route::get('storage/{folder}/{filename}','FileController#getFile');
inside the Controller the getFile method have following code
$path = storage_path($folder . DIRECTORY_SEPARATOR . $filename);
if (extension_loaded('fileinfo')) {
if (!File::exists($path)) {
abort(404);
}
$file = File::get($path);
$type = File::mimeType($path);
$response = Response::make($file, 200);
$response->header("Content-Type", $type);
return $response;
}
else{
abort(412,'please enable the fileinfo extension or contact site administration');
}
when i try to retrieve the image from url it return the blank image like this
blank image
but when i try to retrive the text file it return the file
Also tried it with Image::make($path) and response()->file($path) when the mime type is image/* still the output is same..
so How do i show my image file from url without using the public folder

This is how i do it... I also check for user permissions but i adapted it to your needs...
public function getFile()
{
$path = storage_path($folder . DIRECTORY_SEPARATOR . $filename);
return response()->file($path);
}

How to return json response and Storage data together in Laravel?

I'm trying to return query data and storage Images from laravel controller. My code looks like following :
class ClaimController extends Controller{
.....
public function show(Claim $claim)
{
$front_image = Storage::disk('do_spaces')->get($claim->images->front_image); //image file
$back_image = Storage::disk('do_spaces')->get($claim->images->back_image); //image
// return $front_image [works]
$claim = Claim::all();
//this throws error
return response()->json([
'claim' => $claim,
'images' => [$front_image, $back_image]
]);
}
}
Now I far I understand return->response()->json([]) doesn't send image file. How I can return all data together to frontend app ?
you have the option to return the images from original server which they are stored in or you can return an encoded version of the image as string and in front end reconstruct it.
$path = 'myfolder/myimage.png';
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);
And then use it in front like this :
var image = new Image();
image.src = 'data:image/png;base64,iVBORw0K...';
document.body.appendChild(image);
This is the link for second part.
You can use Storage::url()
$st=\Illuminate\Support\Facades\Storage::disk('do_spaces')->url($claim->images->front_image);
dd(url($st));
Storage::url() return image path and then url() will return full url path
"http://127.0.0.1:8000/storage/imagefolder/filename"
Make sure to symbolic link to storage folder by running following command
php artisan storage:link
Also you can do the following without storage url
asset('storage/'.$claim->images->front_image)

How to Delete Images from Public/Images Folder in laravel 5 (URL Data)

how to delete images file from public/images folder in laravel 5 ??
i found some example from this site, but i know they are just using the file name in their record table, but i'm using something like URL e.g localhost/project/uploads/filename.jpg on my record table. so if i tried like this :
$image_path = $data->image; // the value is : localhost/project/image/filename.format
if(File::exists($image_path)) {
File::delete($image_path);
}
the file is not deleted
help pls, thanks
If you want to delete image from your server, you have to reference location of file in directory server, means you could not reference by url link to delete it.
Commonly, Laravel 5 file is locate in public folder.
Example: your files are located in public/images
$image_path = "/images/filename.ext"; // Value is not URL but directory file path
if(File::exists($image_path)) {
File::delete($image_path);
}
If I can delete image from server by reference URL then Google is the first target :)
You can use the normal PHP delete file keyword ( #unlink )
$image_path = "the name of your image path here/".$request->Image;
if (file_exists($image_path)) {
#unlink($image_path);
}
This is what I do to delete an image:
public function SliderDelete(String $slider_id)
{
$slider = Slider::findOrFail($slider_id);
$image_path = public_path("\storage\images\sliders\\") .$slider->photo;
if(File::exists($image_path)) {
File::delete($image_path);
}
else{
$slider->delete();
//abort(404);
}
$slider->delete();
return response()->json(['success'=>'Slider deleted successfully!']);
}
in laravel 8 you do it like
// import Storage class
use Illuminate\Support\Facades\Storage;
Storage::disk('public')->delete('path-of-file');
you can use disk of your choice like
Storage::disk('s3')->delete('path-of-file');
$filename = public_path($fileloc);
if(File::exists($filename)) {
File::delete($filename);
}
call this function and pass two parameter
$filepath = path where your file exist
$filename = name of your file
public static function UnlinkImage($filepath,$fileName)
{
$old_image = $filepath.$fileName;
if (file_exists($old_image)) {
#unlink($old_image);
}
}
public function destroy($id)
{
$imagePath = YourModelName::select('image')->where('id', $id)->first();
$filePath = $imagePath->image;
if (file_exists($filePath)) {
unlink($filePath);
YourModelName::where('id', $id)->delete();
}else{
YourModelName::where('id', $id)->delete();
}
}
To be able to delete the image it should be in the following form :
"/uploads/img1.jpg" where uploads directory is in the public directory then use the following code:
$image_path = puplic_path("/uploads/img1.jpg")
if (file_exists($image_path)) {
File::delete($image_path);
}
Here is the correct and easy way .
if (file_exists(public_path() . '/storage/gallery/images/'. $item->image)) {
unlink(public_path() . '/storage/gallery/images/'. $item->image);
}

Get image in storage in Laravel 5.2

I have an image in storage->app->upload->images->1472803410756.jpg. When I type url http://localhost:8012/demo/storage/app/upload/images/1472803410756.jpg, browser show my image exactly. But run with php artisan serve, url: http://localhost:8000/storage/app/upload/images/1472803410756.jpg browser not found my image. How can fix it?
My html code:
<td><img class="table_image" src="{{asset("storage/app/upload/images/$product->product_image")}}"></td>
This is wrong way you get the image from storage folder.Because storage folder having only write permissions. So, Firstly you need to create the route of storage path
enter code here
Route::get('storage/{filename}', function ($filename)
{
$path = storage_path('app/upload/images/' . $filename);
if (!File::exists($path)) {
abort(404);
}
$file = File::get($path);
$type = File::mimeType($path);
$response = Response::make($file, 200);
$response->header("Content-Type", $type);
return $response;
});
After that your img tag look like this:-
<td><img class="table_image" src="{{url("storage/".$product->product_image)}}"></td>
Hope it helps!

Laravel Access Images outside public folder

I need to store images in a backend for logged in users. The stored images need to be protected and not visible from the outside (public). I choosed a "storage" folder for this.
I came up with this in my Controller:
public function update(Request $request, $id)
{
//Show the image
echo '<img src="'.$_POST['img_val'].'" />';
//Get the base-64 string from data
$filteredData=substr($_POST['img_val'], strpos($_POST['img_val'], ",")+1);
//Decode the string
$unencodedData=base64_decode($filteredData);
//Save the image
$storagepath = storage_path('app/images/users/' . Auth::user()->id);
$imgoutput = file_put_contents($storagepath.'/flyer.png', $unencodedData);
return view('backend.flyers.index')->withImgoutput($imgoutput)
//->withStoragepath($storagepath);
}
after hitting the save button, which triggers the update() I am able to see the image in my view, and it is also stored in my folder (current users=10) "storage/app/images/users/10/flyer.png"
my question is how can I access the image path?
I want to show the stored image with img src="">. I have no idea what to put inside "src= ..."
While dealing with user file uploads in web applications, the major aspect is about user's content's security.
One should use secure way to upload private files of a user in web applications.
As in your case, you want to access user's image outside public folder.
This can be done in a most secure way as given below.
First of all create a directory right in the root directory of Laravel (where the public folder is located), let the directory's name be uploads. Use this directory to upload private user files.
In the case of images create an another directory inside uploads as uploads/images/ inside uploads directory so that you can have a different storage locations for different type of files.
Remember to upload the image in images directory with a different name and without their extensions so that it looks like a extension-less file.
Keep the file name and its extension in the database which can be used later to retain image's location.
Now you need to create a separate route to show user's image.
Route::get('users/{id}/profile_photo', 'PhotosController#showProfilePhoto')->name('users.showProfilePhoto');
PhotosController.php
class PhotosController extends Controller {
private $image_cache_expires = "Sat, 01 Jan 2050 00:00:00 GMT";
public function showProfilePhoto($id) {
$user = User::find($id);
$path = base_path() . '/uploads/images/';
if($user && $user->photo) // Column where user's photo name is stored in DB
{
$photo_path = $path . $user->photo; // eg: "file_name"
$photo_mime_type = $user->photo_mime_type; // eg: "image/jpeg"
$response = response()->make(File::get($photo_path));
$response->header("Content-Type", $photo_mime_type);
$response->header("Expires", $this->image_cache_expires);
return $response;
}
abort("404");
}
}
The method above inside PhotosController - showProfilePhoto($user_id) will run as soon as you access the route named - users.showProfilePhoto.
Your HTML code will look like this.
<img src="<?php echo route('users.showProfilePhoto', array('id' => $user->id)); ?>" alt="Alter Text Here">
The above code will work like a charm and the image will be shown to the user without declaring/publishing the proper image path to public.
According to me this is the secure way to deal with file uploads in web applications.
You can do this like this:
Route::get('images/{filename}', function ($filename)
{
$path = storage_path() . '/' . $filename;
if(!File::exists($path)) abort(404);
$file = File::get($path);
$type = File::mimeType($path);
$response = Response::make($file, 200);
$response->header("Content-Type", $type);
return $response;
});
Reference:
Laravel 5 - How to access image uploaded in storage within View?
Or Alternatively you can use this library: https://github.com/thephpleague/glide
Just use composer to install it in your project
By default, this will render images from your storage, and allow you to do all sorts of things with it such as cropping, color correction etc.
Reference:
http://glide.thephpleague.com/
https://laracasts.com/discuss/channels/laravel/laravel-5-how-can-we-access-image-from-storage?page=1
Atimes you might have some images you do not wish to store in public directory for some various reasons.
Although storing your images has lots of advantages.
There are many ways you can achieve this, however I have this simple solution.
You should create a helper class like so if already don't have one
<?php namespace App\Services;
class Helper
{
public function imageToBase64($path)
{
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
return 'data:image/' . $type . ';base64,' . base64_encode($data);
}
}
Then in your view (blade)
#inject('helper', 'App\Services\Helper')
<img width="200" height="250" src="{{$helper->imageToBase64(storage_path('app/images/users/' . Auth::user()->id)}}">
It will work 100% work. Open file filesystem in app/config/filesystem.php and write like that
'profile' => [
'driver' => 'profile',
'root' => '/home/folder/public_html/projectname/public/profiles',
],
Add this file at top
use Illuminate\Support\Facades\Storage;
My variable name is
$directoryName = 'profile';
$imageName = $request->image; // image is array of base64 encoded urls
$directory_path ='profiles';
Below function save your file in public/profiles folder.
function UploadImagesByBase64($directoryName, $imageName,$directory_path)
{
$data = array();
$image = $imageName;
foreach ($image as $image_64) {
if($image_64 !=null){
$extension = explode('/', explode(':', substr($image_64, 0, strpos($image_64, ';')))[1])[1]; // .jpg .png .pdf
$replace = substr($image_64, 0, strpos($image_64, ',')+1);
// find substring fro replace here eg: data:image/png;base64,
$image = str_replace($replace, '', $image_64);
$image = str_replace(' ', '+', $image);
$imageName = Str::random(10).time().'.'.$extension;
Storage::disk($directoryName)->put($imageName, base64_decode($image));
$data[] = $directory_path.'/'.$imageName;
}
}
$imageName = implode(',', $data);
return $imageName;
}

Laravel: load images stored outside 'public' folder

I'm trying to display an image stored outside the 'public' folder in my view. These are simple profile images whose paths are stored in the DB. The path looks like
/Users/myuser/Documents/Sites/myapp/app/storage/tenants/user2/images/52d645738fb9d-128-Profile (Color) copy.jpg
Since the image is stored a DB column for each user, my first thought was to create an Accessor in the User model to return the image. I tried:
public function getProfileImage()
{
if(!empty($this->profile_image))
{
return readfile($this->profile_image);
}
return null;
}
That produced unreadable characters in the view. I also tried file_get_contents() in place of read file. Any suggestions about how this might be accomplished?
How about this (just tested it myself and it works):
The view:
<img src="/images/theImage.png">
Routes.php:
Route::get('images/{image}', function($image = null)
{
$path = storage_path().'/imageFolder/' . $image;
if (file_exists($path)) {
return Response::download($path);
}
});
Here is a slightly modified version of #Mattias answer. Assume the file is in the storage/app/avatars folder which is outside the web root.
<img src="/avatars/3">
Route::get('/avatars/{userId}', function($image = null)
{
$path = storage_path().'/app/avatars/' . $image.'.jpg';
if (file_exists($path)) {
return response()->file($path);
}
});
Probably needs and else. Also I have wrapped mine inside the middleware auth Route Group which means you have to be logged in to see (my requirements) but I could do with more control over when it is made visible, perhaps alter the middleware.
EDIT
Forgot to mention that this is for Laravel 5.3.
Here's what I came up with:
I'm trying to show the images in the view, not download. Here's what I came up with:
Note that these images are stored above the public folder, which is why we have to take extra steps to display the image in the view.
The view
{{ HTML::image($user->getProfileImage(), '', array('height' => '50px')) }}
The model
/**
* Get profile image
*
*
*
* #return string
*/
public function getProfileImage()
{
if(!empty($this->profile_image) && File::exists($this->profile_image))
{
$subdomain = subdomain();
// Get the filename from the full path
$filename = basename($this->profile_image);
return 'images/image.php?id='.$subdomain.'&imageid='.$filename;
}
return 'images/missing.png';
}
public/images/image.php
<?php
$tenantId = $_GET["id"];
$imageId = $_GET["imageid"];
$path = __DIR__.'/../../app/storage/tenants/' . $tenantId . '/images/profile/' . $imageId;
// Prepare content headers
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$mime = finfo_file($finfo, $path);
$length = filesize($path);
header ("content-type: $mime");
header ("content-length: $length");
// #TODO: Cache images generated from this php file
readfile($path);
exit;
?>
If somebody has a better way, please enlighten us!! I'm very interested.
