Answer 1

Try this
First of all change route to
Route::get('/getPDF/{id}', 'yourController#getPDF');
Pass the Searched Student id from single view to PDF view like this
Print
and in your PDF Controller
public function getPDF(Request $request,$id){
$student = Student::findOrFail($id);
$pdf = PDF::loadView('pdf.result',['student' => $student]);
return $pdf->stream('result.pdf', array('Attachment'=>0));
}
and get the object in your view like
{!! $student->property !!}

When you call PDF::loadView() I think you need to include the search results, just as you do in search()
$keyword = Input::get('keyword');
$row = Student::where('rollno',$keyword)->first();
$rollno = $row['rollno'];
if($keyword == $rollno){
$results = Student::where('rollno',$keyword)->get();
$pdf = PDF::loadView('results.single', [
'search' => $results,
'keyword' => $keyword
]);
return $pdf->stream('result.pdf');
}
