Unable to save multiple images in database Laravel 5

I have a table named "cases" where the column are id image1,content1,image2,content2,image3 ,content3 .created_at,updated_at

My content1,content2,content3 will be saved in database when i submit it from form but images are nither saved in folder nor in database. controller

public function store(Request $request,SidContainRequest $request)
    {
        $sidContain = new sidcontain;

        $sidContain->content1 = $request->get('page_content1');
        $sidContain->content2 = $request->get('page_content2');
        $sidContain->content3 = $request->get('page_content3');

        //upload multiple files 
        $files= [];

        if($request->file('leftimage'))   $files[] = $request->file('leftimage');
        if($request->file('Middleimage')) $files[] = $request->fiel('Middleimage');
        if($request->file('Rightimage'))  $files[] = $request->file('Rightimage');

          foreach($files as $file)
          {
             if(!empty($file))
             {
                $filename[] = $file->getClientOrginalName();
                if(isset($filename)){
                $file->move(base_path().'/frontend/sidimage/',end($filename));
           }
       }
        $sidContain->image1 = $filename[0];
        $sidContain->image2 = $filename[1];
        $sidContain->image3 = $filename[2];





        }

        $saved = $sidContain->save();
        if($saved)
        {
            \Session::flash('flash_message','Report Added Successfully!');
            return Redirect::to('administrator/sidConatin/create');
        }
