Creating PDF using TCPDF on ajax call

I am using the TCPDF class to create a PDF. First I send some data in json (jquery) format, then I would like to generate a PDF with this data.

Could you tell me if I am right. I have to create a PDF file, save it on the server, and then if the ajax call returns success, redirect the user to this pdf file. Good way?

I have:

$.ajax({ url: '/pdf/fiele_to_generate_pdf.php', type: 'POST', contentType: "application/json; charset=utf-8", data: $.toJSON(jsonObj), processData: false, dataType: 'html', async: false, success: function(html) { window.location.href = '/pdf/example.pdf'; } });

Thanks for any advice.

Edit: So, I sent a request to create a PDF file via Ajax to the server, then the pdf file was generated and saved on the server. Then I used window.location.href to redirect the user to this pdf file. Everything works, but I would like to avoid saving the file to the server. Any ideas?

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

the trick is to use the output method using "F" or "I":

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

CODE

 <?php class 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); ?>
