    </div>
</div>
    </div>



 <script src="//cdn.ckeditor.com/4.22.1/full/ckeditor.js"></script>

  <script>
CKEDITOR.replace('content', {
    filebrowserUploadUrl: "{{ route('pages.image').'?_token'.csrf_token() }}",
    filebrowserUploadMethod: 'form'
});
   </script>

My Controller

   public function upload(Request $request)
{
    if ($request->hasfile('upload')) {
        $originName = $request->file('upload')->getClientOriginalName();
        $fileName = pathinfo($originName, PATHINFO_FILENAME);
        $extension = $request->file('upload')->getClientOriginalExtension();
        $fileName = $fileName . '.' . time() . '.' . $extension;

        $request->file('upload')->move(public_path('uploads/pages/content/'));

        $CKEditorFuncNum = $request->input('CKEditorFuncNum');
        $url = asset('uploads/pages/content' . $fileName);
        $msg = 'Image Uploaded Successfully';
        $response = "<script>window.parent.CKEDITOR.tools.callFunction($CKEditorFuncNum, '$url', '$msg)</script>";

        @header('Content-type: text/html; charset=utf-8');
        echo $response;
    }
       }

And My Route

  Route::get('pages', [PagesController::class, 'index'])->name('pages.index');
  Route::get('/pages/create', [PagesController::class, 'create'])->name('pages.create');
  Route::post('/pages/create', [PagesController::class, 'store'])->name('pages.store');
  Route::get('/pages/{id}/edit', [PagesController::class, 'edit'])->name('pages.edit');
  Route::get('/pages/image', [PagesController::class], 'upload')->name('pages.image');
