Laravel 5.5 - multiple images upload

Question

I have this function in my controller:

use File;
use Image; //image intervention library
...
public function upload(Request $request)
    {
        //make sure there is a folder in public with the username
        $username = Auth::user()->name;
        $folderpath = public_path('images/' . $username . '/');
        File::makeDirectory($folderpath, $mode = 0777, true, true);

        $files = $request->file;

        if(!empty($files)):
            foreach($files as $file):
                $filename = 'post_' . time() . '.' . $file->getClientOriginalExtension();
                $path = $folderpath . $filename;
                Image::make($file)->resize(800,400)->save($path);
            endforeach;
        endif;

        return 'success';
    }

which only save the last image if I upload multiple.

and I tried:

public function upload(Request $request)
    {
        //make sure there is a folder in public with the username
        $username = Auth::user()->name;
        $folderpath = public_path('images/' . $username . '/');
        File::makeDirectory($folderpath, $mode = 0777, true, true);

        $files = $request->file;

        if(!empty($files)):
            foreach($files as $file):
                $filename = 'post_' . time() . '.' . $file->getClientOriginalExtension();
                $path = $folderpath . $filename;
                $file->save($path);
            endforeach;
        endif;

        return ''success;
    }

which throw me error:

Method save does not exist.

I goggled and it seems like I did not instantiate it with model. But in this case, how can I instantiate it with model if it is just a direct file upload?

What is the best way for multiple images upload in laravel ?

Update

After reading @kunal's answer, I managed to solve the issue by adding a unique number for the file name:

public function upload(Request $request)
    {
        //make sure there is a folder in public with the username
        $username = Auth::user()->name;
        $folderpath = public_path('images/' . $username . '/');
        File::makeDirectory($folderpath, $mode = 0777, true, true);

        $files = $request->file;
        $count = 0;//<-- add a counter
        if(!empty($files)):
            foreach($files as $file):
                $filename = 'post_' . time() . '_' . $count . '.' . $file->getClientOriginalExtension();//<-- add counter to the file name
                $path = $folderpath . $filename;
                Image::make($file)->resize(800,400)->save($path);
                $count ++;//<-- increase the value
            endforeach;
        endif;

        return 'success';
    }

Answer 1

I am thinking u may missed this part

<input type="file" id="gallery" name="file[]" />

note the file[] it must be array otherwise it will only save the last image if upload multiple image

If u did ur html part correct, then use like this,

foreach ($file as $photo) {
    $path = Storage::putFile('foldername', $photo);
}

Answer 2

try this code:

$files= Input::file('image');
$destinationPath= 'images';
$images=array(); 
foreach($files as $file){
    $fullname= $file->getClientOriginalName(); 
    $hashname  = $fullname; 
    $upload_success   =$file->move($destinationPath, $hashname);
    $images[]=$fullname;
    $has= implode(",",$images);
}
$modelname= new Modelname;
$modelname->image_attachment    =  $has;  
$modelname->save();

and yout html page:

<input type="file" id="image" name="image[]" />

May be you are looking for this kind of stuff:-

if ($request->hasFile('files')) {
$files = $request->file('files');
foreach($files as $file){
    $extension = $file->getClientOriginalExtension();
    $fileName = str_random(5)."-".date('his')."-".str_random(3).".".$extension;
    $folderpath  = 'images'.'/';
    $file->move($folderpath , $fileName);
}
}
<input type="file" id="gallery" name="files[]" multiple />

Answer 4

It is not that complicated. As of larval 5.8 you can do this:

collect($request->images)->each(function ($image) {
    return $image->store('images', 'public');
});

It puts images in images folder of public disk.
