Strange error message when generating dynamic iCalendar events

Posted on 2008-06-11

I am using PHP to generate iCalendar events using data from a MySQL DB.  To my eye, the .ics file it generates is well formed, but I keep getting an import error that says "This error can appear if you have attempted to save a recurring Lunar appointment in iCalendar format. To avoid this error, set the appointment option to Gregorian instead of Lunar."  I can not figure out what's wrong.  Below is the code, attached is a sample .ics file that this code generates (in txt format due to upload restrictions).  Any help would be appreciated, thanks!
<?php
    header("Content-Type: text/Calendar");
    header("Content-Disposition: inline; filename=sample.ics");
	
	include_once("config.inc");
	include_once("display-functions.inc");
 
	$intTrainingID=$_REQUEST['id'];
 
	$qr="SELECT * FROM tblTrainingClasses WHERE intTrainingID='$intTrainingID'";
	$result=odbc_exec($dbconn, $qr) or die ("Could not execute query...".obdc_errormsg($dbconn));
  	$intUserID=odbc_result($result,"intUserID");
  	
  	$datClassEnd=odbc_result($result,"datClassEnd");
  	$datRequest=odbc_result($result,"datRequest");
 
	$vCalStart = date("Ymd", strtotime($datClassStart))."T090000";
	$vCalEnd = date("Ymd", strtotime($datClassEnd))."T180000";

You might want to lose that VERSION statement.  See the post here:
http://calendarswamp.blogspot.com/2005/08/outlook-2003-for-ical-import-use.html

I've attached my own iCal code below that seems to be working OK.  There are some function calls that may look kind of "pidgin" but I'm sure you will be able to see the patterns OK.

HTH, ~Ray
<?php // LAPRBass vcal_generator.php
$config_page= getcwd() . '/_config.php'; require_once($config_page);
 
$t_key	= get_clean_numeric_string($_GET[t]);
if (!is_numeric($t_key)) { die("Error T"); }
 
$tsql	= "SELECT * FROM {$my_dbt_prefix}_TOURNAMENTS WHERE _key = $t_key LIMIT 1";
if (!$t	= mysql_query("$tsql", $db_connection)) { non_fatal_query_error($tsql); die(); }
if (!$t_rows= mysql_num_rows($t)) { die("Error T=$t_key"); }
$trow	= mysql_fetch_assoc($t);
foreach ($trow as $k => $v) { $$k = stripslashes($v); } 
 
$csql	= "SELECT * FROM {$my_dbt_prefix}_SERIES WHERE _key = $c_key LIMIT 1";
if (!$c	= mysql_query("$csql", $db_connection)) { non_fatal_query_error($csql); die(); }
if (!$c_rows= mysql_num_rows($c)) { die('Error C=$c_key'); }
$crow	= mysql_fetch_assoc($c);
foreach ($crow as $k => $v) { $$k = stripslashes($v); }
 
$p_date		= date('l, F j, Y', strtotime($date));
$p_start	= date('g:ia', strtotime($start));
$p_finish	= date('g:ia', strtotime($finish));
$my_start	= date('D, M j, Y g:ia', strtotime($p_date .' '. $p_start));
 
$vcalstart	= date("Ymd", strtotime($date)) .'T'. date("His", strtotime($start));
$vcalend	= date("Ymd", strtotime($date)) .'T'. date("His", strtotime($finish));
 
$summary	 = "LAPRBASS Tournament: $p_date";
 
$dump		 = "";
$dump		.= "$year $name" . "=0D=0A";
$dump		.= "Mark your calendar for $my_start" . "=0D=0A";
if ($launch != "") { $dump .= "Launch: $launch" . " =0D=0A"; }
if ($title  != "") { $dump .= "$title" . " =0D=0A"; }
$dump		.= "http://www.LAPRBASS.com" . "=0D=0A";
 
$filename = "LAPRBASS" . $t_key . ".vcs";
 
header("Content-Type: text/x-vCalendar");

Hi Ray, sorry for the delayed response, I got temporarily moved to a different project.  I tried a very similar variation of this code at one point.  After more testing I actually determined that the error was an error being output by my config file which I had included.  This code is definitely working for me now that I fixed my other situation.  Thanks!
