saving file generated by TCPDF

问题

I'd like to generate and open PDF when user clicks on a button. Here is my code so far:

index.php:

</html>
<head>
<script>
$('.cmd_butt').click(function() {
    $.ajax({
    url: 'create_pdf.php',
    data: {id: $(this).attr('order_id'), name: $(this).attr('name')},
    type: 'post'
    });
}
</script>
</head>
<body>
<button class="cmd_butt" order_id="250" name="pdf_but">Download PDF</button>
</body>
</html>

create_pdf.php:

<?php

//header('Content-type: application/pdf')
header("Content-type: application-download");
//header("Content-Length: $size");
header("Content-Disposition: attachment; filename=MyPDF.pdf");
header("Content-Transfer-Encoding: binary");

require_once('tcpdf/config/lang/eng.php');
require_once('tcpdf/tcpdf.php');

// create new PDF document
// some code
// some code

//$pdf->Output('test.pdf', 'I');
//$pdf->Output('test.pdf', 'FD');
$pdf->Output();

?>

How can I open a new window with generated PDF? Or notify user with "save as" dialog to download this PDF? I've tried different Output() combinations but none of them worked.

回答1:

Ajax can only fetch textual data, it can't show the PDF directly or in a new window (from response).

You need to either submit form instead of AJAX, or create a file from ajax call and in response, gets a response about creation of file. e.g. created file name, and than open a new window based on that.

回答2:

Have you tried this

$pdf->Output('yourfilename.pdf','D');

This will prompt the user to choose where to save the PDF file.

回答3:

Change

<button class="cmd_butt" order_id="250" name="pdf_but">Download PDF</button>

<a href="create_pdf.php?order_id=250" target="_blank">Download PDF</a>

Remove the java in index.php
Remove the headers in create_pdf.php
