Question

在Moodle我正在使用javascript在course中使用information PDF打印页面（在单独的文件中使用TCPDF library）

javascript：

    $( document ).ready(function() {
$('#page-enrol-index .printpdf').click(function(){
        //jquery extend function
        $.extend(
        {
            redirectPost: function(location, args)
            {
                var form = '';
                $.each( args, function( key, value ) {
                    form += '<input type="hidden" name="'+key+'" value="'+value+'">';
                });
                $('<form action="'+location+'" method="POST">'+form+'</form>').appendTo('body').submit();
            }
        });

        //fill the variables
        var title = $("div.sessioninfo_title span.sessioninfodata").text();
        var description = $("div.content div.summary").text();
        console.log(title);


        //create the pdf
        $.redirectPost("/moodle/local/printpdf.php", {
            ptitle: title, 
            pdesc: description, 
        });
    });
});

PDF（两个variables $title和$description，不会打印）：

    if (@file_exists(dirname(__FILE__).'/lang/eng.php')) {
    require_once(dirname(__FILE__).'/lang/eng.php');
    $pdf->setLanguageArray($l);
}
$pdf->SetFont('helvetica', '', 9);
$pdf->AddPage();

if (!empty($_POST["ptitle"])) {
    $title = $_POST["ptitle"];
    $description = $_POST["pdesc"];
}

$html = '<html>
<body>
<img src="/moodle/theme/base/pix/logo.png" alt="test alt attribute" border="0" height="100" width="220" allign="left" /><br />
<p><span style="font-size: small;"><font color="#C0C0C0">Organisation name<br><b>Department<br></font></span></p>
<h2>Information about the course</h2>
<!-- 
<h3>'. $title . '</h3><br />
'. $description . '<br />
-->
</body>
</html>';



// $pdf->writeHTML($html, true, false, true, false, '');

$pdf->writeHTML($html, true, false, true, false, '');

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

打印PDF | Javascript无法获取数据
