如何使用参数保存带有FDPF的PDF？(How do you save a PDF with FDPF using parameters?)

 我有这个按钮，它与这个功能有关： 
 
$('#genPDF').click(function () {

    var str = "hText=something" +
        "&cText=also something";

    $.ajax({
        url: "/wp-content/themes/mytheme/indexpdf.php",
        data: str,
        cache: false,
        success: function (result) {
            console.log("Success!");
            $("#pdfobject").attr("src", "/wp-content/themes/mytheme/flyer.pdf");
            var container = document.getElementById("pdfContainer");
            var content = container.innerHTML;
            container.innerHTML = content;
        }
    });
});
 
 为了解释成功的ajax代码的作用，首先输出“成功！” 在浏览器中的控制台中，然后用修改后的链接替换页面上的某个div（刷新页面的某个部分）。 
 
 上面的代码工作，并使它转到indexpdf.php，这是： 
 
<?php

    $hText = trim(isset($_GET['hText']) ? $_GET['hText'] : '');
    $cText = trim(isset($_GET['cText']) ? $_GET['cText'] : '');

    require_once('fpdf.php');
    require_once('fpdi.php');

    // initiate FPDI
    $pdf = new FPDI();

    $pdf->AddPage();

    $pdf->setSourceFile("TestFlyer.pdf");

    $tplIdx = $pdf->importPage(1);

    $pdf->useTemplate($tplIdx, 10, 10, 100);

    $pdf->SetFont('Helvetica');
    $pdf->SetTextColor(255, 0, 0);
    $pdf->SetXY(30, 30);
    $pdf->Write(0, $hText.$cText);

    $pdf->Output("D","flyer.pdf");
?>
 
 问题是，它应该采用testflyer.pdf，加载它的第一页并将传入的参数写入其中。 然后，将自己保存为flyer.pdf。 
 
 这不是保存，我不知道正在做什么或问题是什么。 
 
 上面的所有PDF和PHP文件都在/ mytheme /文件夹中。 

I have this button, that is tied to this function:
 
$('#genPDF').click(function () {

    var str = "hText=something" +
        "&cText=also something";

    $.ajax({
        url: "/wp-content/themes/mytheme/indexpdf.php",
        data: str,
        cache: false,
        success: function (result) {
            console.log("Success!");
            $("#pdfobject").attr("src", "/wp-content/themes/mytheme/flyer.pdf");
            var container = document.getElementById("pdfContainer");
            var content = container.innerHTML;
            container.innerHTML = content;
        }
    });
});
 
To explain what the successful ajax code does, first outputs "success!" in the console, which the browser does, then replaces a certain div on the page with a revised link (refreshing a certain part of the page).
 
This above code works, and makes it's way over to indexpdf.php, which is:
 
<?php

    $hText = trim(isset($_GET['hText']) ? $_GET['hText'] : '');
    $cText = trim(isset($_GET['cText']) ? $_GET['cText'] : '');

    require_once('fpdf.php');
    require_once('fpdi.php');

    // initiate FPDI
    $pdf = new FPDI();

    $pdf->AddPage();

    $pdf->setSourceFile("TestFlyer.pdf");

    $tplIdx = $pdf->importPage(1);

    $pdf->useTemplate($tplIdx, 10, 10, 100);

    $pdf->SetFont('Helvetica');
    $pdf->SetTextColor(255, 0, 0);
    $pdf->SetXY(30, 30);
    $pdf->Write(0, $hText.$cText);

    $pdf->Output("D","flyer.pdf");
?>
 
The problem is, it's supposed to take testflyer.pdf, load it's first page and write my passed in arguments into it. THEN, save itself as flyer.pdf.
 
It's not saving, I don't know what's doing on or what the problem is.
 
All PDF's and PHP files above are in the /mytheme/ folder.
