Hiya,

I'm trying to generate Outlook event files for my events, doing so on the fly as and when someone requests it by pressing a link on the page.

Here's what i've got so far, but I can't find out how to get the browser to download the content which is returned.

I know how I could do this if I sent everything via _GET, but I'd prefer to do it via _POST, hence I'm going down this route..

Any thoughts? Thanks!

HTML / Javascript

<script>
$(function() {
    $(".button").click(function() {
        // validate and process form
        // first hide any error messages
        var start = $("input#start").val();
        var end = $("input#end").val();
        var dataString = 'start='+ start + '&end=' + end;
        $.ajax({
            type: "POST",
            url: "/calendar.php",
            data: dataString,
            success: function(data) {
                //Need to return the file contents somehow!
            }
        });
    return false;
    });
});
</script>
<form name="calendar" method="post" action="">
      <input type="hidden" name="start" id="start" value="<?php echo $start; ?>" />
      <input type="hidden" name="end" id="end" value="<?php echo $end; ?>" />
      <input type="submit" name="submit" class="button" id="submit_btn" value="Outlook" />
    </fieldset>
</form>

PHP File

<?php
if (isset($_POST['start'])) {
    $start = $_POST['start'];
    $end = $_POST['end'];
    $c = header("Content-Type: text/Calendar");
    $c .= header("Content-Disposition: inline; filename=calendar.ics");
    $c .= "BEGIN:VCALENDAR\n";
    $c .= "VERSION:2.0\n";
    $c .= "PRODID:-//xxxyyyy//NONSGML //EN\n";
    $c .= "METHOD:REQUEST\n"; // requied by Outlook
    $c .= "BEGIN:VEVENT\n";
    $c .= "UID:". $start . $end ."-" . "-xxxxyyyy.com\n"; // required by Outlook
    $c .= "DTSTAMP:".date('Ymd').'T'.date('His')."\n"; // required by Outlook
    $c .= "DTSTART:20080413T000000\n"; 
    $c .= "SUMMARY:" . "\n";
    $c .= "DESCRIPTION:" .  "\n";
    $c .= "END:VEVENT\n";
    $c .= "END:VCALENDAR\n";
    echo $c;        
} else {
    echo "Sorry you can't access this page directly";   
}
?>
