how to upload image in laravel

In above video we will learn how to upload file like JPG,PNG,GIF etc by using laravel framework and also set validation before upload an image.

Step 1: Set file upload control in view file

<form role="form" name="gallery-form" id="gallery-form" method="post" action="{{ url('/admin/gallery-store') }}" enctype="multipart/form-data">

	<input type="file" name="image" id="image">

	<button type="submit" class="btn btn-primary pull-right"></button>

</form>

Step 2: Set route path

Route::post('/admin/gallery-store', 'Admin\GalleryController@store');

Step 3: Use below pre-define class

use Image;
use File;

Step 4: Use below function to set validations and file upload on server

public function store(Request $request)
    {
        //validation before insertion
       $mime = $request->file('image')->getMimeType();//returns text/plain
       

        $this->validate($request,
            [
                'image' => 'required|mimes:jpeg,jpg,png|max:10000'
            ],
            [
                'image.required' => 'Plese, select gallery image.',
                'image.mimes' => 'The gallery image must be a file of type: jpeg, jpg, png.',
                'image.max' => 'The image may not be greater than 10 mb.'
            ]
        );

        $image = $request->file('image');
        
       //check image select or not
        if(empty($image))
        {
            $imagename=''; 
        }
        else
        {
            $imagename = time().'.'.$image->getClientOriginalExtension();
            
            
            $thumnailPath = public_path('/upload/gallery/thumnail/');
            $orignalimagePath = public_path('/upload/gallery/');
            
            
            /* ----------- check directory exist or not strat ------------ */
            File::isDirectory($thumnailPath) or File::makeDirectory($thumnailPath, 0777, true, true);
            /* ----------- check directory exist or not end ------------ */
            

            //------- Genrate thumnail image
            $thumnailImg=Image::make($image)->resize(600, null, function ($constraint) {
                $constraint->aspectRatio();
            });
            $thumnailImg->save($thumnailPath.$imagename);
            
            //------- Genrate orignal image
            $orignalImg=Image::make($image)->resize(1200, null, function ($constraint) {
                $constraint->aspectRatio();
            });
            $orignalImg->save($orignalimagePath.$imagename);
            
        }
