I need help for my laravel project. I am using Fpdi to import PDF but when I display it on localhost, I have only unicode characters like this :

%PDF-1.4 3 0 obj <> endobj 4 0 obj <> stream x�E�K�0D�9�,a�:i�d��H�|�4�ⓠr|�!y�aƗ!C*�r�y���{�98
L>|a�)w endstream endobj 1 0 obj <> endobj 5 0 obj <> stream x�]R�n�0�

Here is my code:

use setasign\ Fpdi;

// initiate FPDI
$pdf = new Fpdi\ Fpdi();
// add a page
$pdf - > AddPage();
// set the source file
$pdf - > setSourceFile(storage_path("justificatif.pdf"));
// import page 1
$tplIdx = $pdf - > importPage(1);
// use the imported page and place it at point 10,10 with a width of 100 mm
$pdf - > useImportedPage($tplIdx, 10, 10, 100);

// now write some text above the imported page
$pdf - > SetFont('Helvetica');
$pdf - > SetTextColor(255, 0, 0);
$pdf - > SetXY(30, 30);
$pdf - > Write(0, 'This is just a simple text');

$pdf - > Output();

My route:

Route::get('/testpdf', function() {
    return view('layouts/essai'); 
});

Why is this happening and how to fix this?

Try to return it like this The browser doesn't know the type of the response unless you send it so it doesn't know it should show a pdf

...
return response($pdf->Output('S'))->withHeaders(['Content-Type' => 'application/pdf']);

Source docs https://laravel.com/docs/5.6/responses#attaching-headers-to-responses

  • The Response content must be a string or object implementing__toString(), "object" given. – Gihad Bayoudh Mar 15 '18 at 19:23
  • no other way to fix this ? maybe my pdf document is not adapt – Gihad Bayoudh Mar 15 '18 at 19:40
  • Hmmm weird, I have an working example the way I answered.. try this `return response($pdf->Output())->withHeaders(['Content-Type' => 'application/pdf']);` – Sérgio Reis Mar 15 '18 at 22:57
  • Update it to `return response($pdf->Output('S'))->withHeaders(['Content-Type' => 'application/pdf']);` to get the PDF [as a string](http://fpdf.org/en/doc/output.htm). – Jan Slabon Mar 16 '18 at 06:53
