How to generate PDF from an active View Laravel
提问by Umair Shah Yousafzai
I have a search box when user input roll no, it returns the specific student result. I want to generate PDF of that searched data, that data is in table.
Main Question : I want to generate PDF for the result of student who has searched for his/her data, so how to generate PDF for that current student result.
当用户输入卷号时，我有一个搜索框，它返回特定的学生结果。我想生成该搜索数据的 PDF，该数据在表中。
主要问题：我想为搜索了他/她的数据的学生的结果生成 PDF，那么如何为当前学生的结果生成 PDF。
Print/PDF Generator Button:
打印/PDF 生成器按钮：
<a href="{!! url('/getPDF') !!}">Print</a>
PDFController:
PDF控制器：
class PDFController extends Controller
{
public function getPDF(Request $request){
// I want some code here to get the current student result so that I can generate pdf for the current student
$pdf = PDF::loadView('results.single');
return $pdf->stream('result.pdf');
}
}
SearchController:
搜索控制器：

$keyword = Input::get('keyword');
$row = Student::where('rollno',$keyword)->first();
$rollno = $row['rollno'];
if($keyword == $rollno){
return View::make('results.single')
->with('search',Student::where('rollno',$keyword)
->get())->with('keyword',$keyword);
}else{
return view('errors.404');
}
}
}

Try this
尝试这个
First of all change route to
首先改变路线
Route::get('/getPDF/{id}', 'yourController@getPDF');
Pass the Searched Student idfrom single view to PDF view like this
id像这样将搜索到的学生从单一视图传递到 PDF 视图
<a href="{!! url('/getPDF', $student->id) !!}"> Print</a>
and in your PDF Controller
并在您的PDF 控制器中
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 objectin your view like
并在您的视图中获取对象，例如
{!! $student->property !!}

When you call PDF::loadView()I think you need to include the search results, just as you do in search()
当你打电话时，PDF::loadView()我认为你需要包括搜索结果，就像你在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');
}
