Generate PDF using TCPDF on ajax call

Ok this script will save the file and also display in the browser

the trick is in using the output method with the 'F' or 'I':

$pdf->Output("your path", 'F');  //save pdf$pdf->Output('file.pdf', 'I'); // show pdf

CODE

<?phpclass PDF extends TCPDF {    public function Header (){                                $this->SetFont('dejavusans', '', 14);         $title = utf8_encode('title');         $subtitle = utf8_encode('sub title');         $this->SetHeaderMargin(40);                     $this->Line(15,23,405,23);          }    public function Footer() {        $this->SetFont('dejavusans', '', 8);        $this-> Cell (0, 5, 'Pag '.$this->getAliasNumPage().'/'.$this->getAliasNbPages(), 0, false, 'R', 0, '', 0, false, 'T', 'M');    }       public static function makeHTML ($json){        $html = '<table border="0.5" cellspacing="0" cellpadding="4">        <tr>            <th bgcolor="#DAB926" style="width:3%; text-align:left"><strong>you th</strong></th>              </tr>';        for ($i=0; $i<count($json); $i++)        {            $a= $i+1;             $html .= '<tr>                        <td style="width:15%; text-align:left">'.$json[$i]->Name.'</td>                      </tr>';        }           $html .= '</table>';        return $html;               }   }function printReport ($json ){    set_time_limit(0);    $pdf = new PDF("L", PDF_UNIT, "A3",true, 'UTF-8', false);    $pdf->SetMargins (15, 27, 15, true);    $pdf->SetFont('dejavusans', '', 8);    $pdf->SetAutoPageBreak(TRUE,50);    $pdf->AddPage();    //create html    $html = $pdf->makeHTML($json);      $pdf->writeHTML($html, false, false, false, false, '');    if (!file_exists("your path"))        mkdir("your path");    $pdf->Output("your path", 'F');  //save pdf    $pdf->Output('file.pdf', 'I'); // show pdf    return true;}$json = json_decode("your json");printReport($json);?>
