Advice add iCal library - El Forum - 06-14-2012

[eluser]Matalina[/eluser]
I am creating a form that will create dates and descriptions in a database for specific dates. These dates need to be sent by email to the person(s) in question with an ical event to be added to their calendars.

Should I just extend the Email class? Or use another class to do this.

*edit* If I extend the Email Class but call the function something else I need to include a require one of the email class correct? *end edit*

My biggest hurdle here is making the email class in CI work with the format of needed.

How do I set the email to multipart in CI? Do you have to have an attachement? As I'm not making an attachment. I have a 'tutorial' showing me how to create the email. I just don't see how it works with the CI email class.

Below is the tutorial function:
Code:
<?PHP

//$firstname is the first name of target
//$lastname is the last name of target
//$email is the targets email address
//$meeting_date is straight from a DATETIME mysql field and assumes UTC.
//$meeting_name is the name of your meeting
//$meeting_duretion is the duration of your meeting in seconds (3600 = 1 hour)

FUNCTION sendIcalEmail($firstname,$lastname,$email,$meeting_date,$meeting_name,$meeting_duration) {

$from_name = "My Name";
$from_address = "[email protected]";
$subject = "Meeting Booking"; //Doubles as email subject and meeting subject in calendar
$meeting_description = "Here is a brief description of my meeting\n\n";
$meeting_location = "My Office"; //Where will your meeting take place


//Convert MYSQL datetime and construct iCal start, end and issue dates
$meetingstamp = STRTOTIME($meeting_date . " UTC");    
$dtstart= GMDATE("Ymd\THis\Z",$meetingstamp);
$dtend= GMDATE("Ymd\THis\Z",$meetingstamp+$meeting_duration);
$todaystamp = GMDATE("Ymd\THis\Z");

//Create unique identifier
$cal_uid = DATE('Ymd').'T'.DATE('His')."-".RAND()."@mydomain.com";

//Create Mime Boundry
$mime_boundary = "----Meeting Booking----".MD5(TIME());

//Create Email Headers
$headers = "From: ".$from_name." <".$from_address.">\n";
$headers .= "Reply-To: ".$from_name." <".$from_address.">\n";
/** Below Here is where I'm having trouble figuring out how to implement in CI Mime I got its the rest**/
$headers .= "MIME-Version: 1.0\n";
$headers .= "Content-Type: multipart/alternative; boundary=\"$mime_boundary\"\n";
$headers .= "Content-class: urn:content-classes:calendarmessage\n";

//Create Email Body (HTML)
$message .= "--$mime_boundary\n";
$message .= "Content-Type: text/html; charset=UTF-8\n";
$message .= "Content-Transfer-Encoding: 8bit\n\n";

$message .= "&lt;html&gt;\n";
$message .= "&lt;body&gt;\n";
$message .= '<p>Dear '.$firstname.' '.$lastname.',</p>';
$message .= '<p>Here is my HTML Email / Used for Meeting Description</p>';    
$message .= "&lt;/body&gt;\n";
$message .= "&lt;/html&gt;\n";
$message .= "--$mime_boundary\n";

//Create ICAL Content (Google rfc 2445 for details and examples of usage)
$ical =    'BEGIN:VCALENDAR
PRODID:-//Microsoft Corporation//Outlook 11.0 MIMEDIR//EN

$message .= 'Content-Type: text/calendar;name="meeting.ics";method=REQUEST\n';
$message .= "Content-Transfer-Encoding: 8bit\n\n";
$message .= $ical;            

//SEND MAIL
$mail_sent = @MAIL( $email, $subject, $message, $headers );

IF($mail_sent)     {
  RETURN TRUE;
} ELSE {
  RETURN FALSE;
}
