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']);
}
}Step 4: View File
