Laravel Crop Image Before Upload using Cropper JS

Today now in this tutorial, I will show you how to use image cropper in laravel application. Here we will know a way of simply and easy to use crop image by using cropper.js in laravel application.

We know that Cropper.js is a very easy and also it is most useful JavaScript/jQuery plugin. For image cropping also with it is support of live previews image and also it custom aspect ratio. Now in this plugin provide us to use a features of move,zoom,rotate, It is Fully responsive and mobile-friendly.

So now is this plugin will displays a resizable grid layer on a given image and also it is allowing to visually resize and it also crop the image.

So now I will use model view in example. And a model display to upload image and also crop image with preview. Just need to follow bellow step example.

Step 1: Create Route

So in this First step, i will create to route in web.php file.

routes/web.php

Route::get('image-cropper','ImageCropperController@index');
Route::post('image-cropper/upload','ImageCropperController@upload');
Step 2: Create Controller

Now in this step,i will create to ImageCropperController.php in controller.

app/Http/Controller/ImageCropperController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class ImageCropperController extends Controller
{

    public function index()
    {
        return view('cropper');
    }

    public function upload(Request $request)
    {
        $folderPath = public_path('upload/');

        $image_parts = explode(";base64,", $request->image);
        $image_type_aux = explode("image/", $image_parts[0]);
        $image_type = $image_type_aux[1];
        $image_base64 = base64_decode($image_parts[1]);
        $file = $folderPath . uniqid() . '.png';

        file_put_contents($file, $image_base64);

        return response()->json(['success'=>'success']);
    }
}
