如何在Laravel中将包含动态数据的HTML刀片从数据库转换为PDF？

Question

I'm trying to write code that converts html blade to PDF using tcpdf in laravel.

This is the controller code which i use to convert:

public function htmlToPDF()
{  
    $view=view('PdfDemo');
    $html_content =$view->render();
    PDF::SetTitle('Sample PDF');
    PDF::AddPage();
    PDF::writeHTML($html_content, true, false, true, false, '');
    PDF::Output('SamplePDF.pdf');
}

When I put static data on my view(PdfDemo) everything runs successfully, but the problem is when I put dynamic data with some variables in the blade as the following:

                        <table>
                          <?php $i=0?>
                            @if(count($names))
                                @foreach($names as $n)
                                    <tr><td>
                                    <label>Name{{$i}}:</label>{{$n}}</td>
                                    <tr><td><hr></td></tr>
                                    <?php $index = $index+1; ?>
                                @endforeach
                            @endif
                        </table>

Here $names is the result of select statement in other function of controller, then I pass it to the blade like this:

 return view('PdfDemo',compact('names'));

In this case the blade appear exactly as I want, but when I try to convert to PDF it shows error, $name not defined.

Answer 1

Do like this:

$view = View::make('PdfDemo',compact('names'));
$contents = (string) $view;
// or
$contents = $view->render();

When you use View::make() it gets the HTML code of blade file as HTML content after adding dynamic variable's values.

Answer 2

You are not passing the data to the view in the htmlToPDF function.

try to change it to:

public function htmlToPDF($names)
{  
    $view=view('PdfDemo', compact('names');
    $html_content =$view->render();
    PDF::SetTitle('Sample PDF');
    PDF::AddPage();
    PDF::writeHTML($html_content, true, false, true, false, '');
    PDF::Output('SamplePDF.pdf');
}
