    $form1->tp=$request->tp;
    $form1->heading=$request->subject;

    $form1->cate=$request->category;
    $form1->image=$filepath;
    $form1->image2=$filepath2;
    $form1->image3=$filepath3;
    $form1->save();
    
    
    //dd($form1);
    $dbreturn=form1::latest()->paginate(8);
    //dd($dbreturn);

Route::get('/home1', function () { $data=App\form1::latest()->paginate(8); return view('home1')->with('form1',$data);
