How to create an outlook calendar meeting request in PHP?
Can someone point me in the right direction? I know it has to do with attaching a .ics file, but I can only get it to the point where a user can download and then import the event into their outlook calendar? How can I programmatically create these meeting requests?
Answer
Here is working example with multiple participants:
<?php
$to = '[email protected],[email protected]';
$subject = "Millennium Falcon";
$organizer = 'Darth Vader';
$organizer_email = '[email protected]';
$participant_name_1 = 'Boushh';
$participant_email_1= '[email protected]';
$participant_name_2 = 'Boba Fett';
$participant_email_2= '[email protected]';
$location = "Stardestroyer-013";
$date = '20131026';
$startTime = '0800';
$endTime = '0900';
$subject = 'Millennium Falcon';
$desc = 'The purpose of the meeting is to discuss the capture of Millennium Falcon and its crew.';
$headers = 'Content-Type:text/calendar; Content-Disposition: inline; charset=utf-8;\r\n';
$headers .= "Content-Type: text/plain;charset=\"utf-8\"\r\n"; #EDIT: TYPO
$message = "BEGIN:VCALENDAR\r\n

$headers .= $message;
mail($to, $subject, $message, $headers);
?>
