PHP KML生成器

已采纳

I am having having trouble with the next step of my KML generator. I have it so when you choose a date it will send the date to the generator and it will create a KML that will then be downloaded. It creates the file but the file that is downloaded is called generator.php. It has all my KML information in it, but that is not quite what I was wanting. So I need a little help or a tutorial on getting the file to be a .kml with preferably a name of my choosing that that will be downloaded. Here is my code so far: index.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
        <title>TDM KML Generator</title>
        <script type="text/javascript" src="calendarDateInput.js"></script>
    </head>
    <body>
    <form action="generator.php" method="post">
        <script type="text/javascript">DateInput('orderdate', true, 'YYMMDD')</script>
        <input name="submit" type="submit" value="get KML" />
    </form>

    </body>
</html>

generator.php

<?php
            if($_SERVER['REQUEST_METHOD'] == 'POST')
            {
                $date = $_POST['orderdate'];
                $file = fopen("http://www.xxxxxxxxxxxxxxxxxxx/".$date."xxxxxxxxx.csv", "r");
                $content = fgetcsv($file, 1000, ",");
                $dom = new DOMDocument('1.0', 'UTF-8'); 

                // Creates the root KML element and appends it to the root document.
                $node = $dom->createElementNS('http://earth.google.com/kml/2.1', 'kml');
                $parNode = $dom->appendChild($node);

                // Creates a KML Document element and append it to the KML element.
                $dnode = $dom->createElement('Document');
                $docNode = $parNode->appendChild($dnode);

                // Creates the two Style elements, one for restaurant and one for bar, and append the elements to the Document element.

                $restStyleNode->appendChild($restIconstyleNode);

    Have a look at Example 1 in the PHP manual for header:

    If you want the user to be prompted to save the data you are sending, such as a generated PDF file, you can use the » Content-Disposition header to supply a recommended filename and force the browser to display the save dialog.

    <?php // We'll be outputting a PDF
    header('Content-type: application/pdf');
    
    // It will be called downloaded.pdf
    header('Content-Disposition: attachment; filename="downloaded.pdf"');
    // The PDF source is in original.pdf
    readfile('original.pdf'); ?>
