ics file for individual events in a series?

[Kelton Turvey]

We have an event which has multiple dates – How can we create an ics file for each of these events so users who book tickets for this certain date can download the correct ics file?

[Stephen Harris]

The plug-in can generate an ics file for the whole series of an individual event, but not individual dates of an event.

If you’re familiar with the iCal specification you could build a string with the details and then attach that as a string attachment. It depends on whether you want to provide a URL which points to an ics feed or whether you’re happy to attach it directly to the email.

To do the latter is a bit involved because WordPress’ wp_mail() only supports attaching files, not strings generated at runtime .However you can use the following code:

<?php
class Myprefix_iCal_Email_Attacher{

    protected $booking_id = false;

    function setup( $attachments, $booking_id ){
        $this->booking_id = $booking_id;
        add_action( 'phpmailer_init', array( $this, 'attach_ical' ), 10 );
        add_action( 'phpmailer_init', array( $this, 'cleanup' ), 11 );
        return $attachments;
    }

    function attach_ical( $phpmailer ){
        if( $this->booking_id ){
            $event_id    = eo_get_booking_meta( $this->booking_id , 'event_id' );
            $occurrence_id    = eo_get_booking_meta( $this->booking_id , 'occurrence_id' );
            $title = esc_attr( get_the_title( $event_id ) );            
            $filename    = sanitize_file_name( $title.'-'.$this->booking_id.'.ics' );
            $ical_string = $this->get_ical( $event_id, $occurrence_id ); 
            $phpmailer->AddStringAttachment( $ical_string, $filename );
            $this->booking_id = false;
        }
    }

    function get_ical( $event_id, $occurrence_id ){
        return "...ics string feed for this event date...";
    }

    function cleanup(){
        remove_action( 'phpmailer_init', array( $this, 'attach_ical' ), 10 );
    }

}
$ical_attacher = new Myprefix_iCal_Email_Attacher();
add_filter( 'eventorganiser_booking_confirmed_email_attachments', array( $ical_attacher, 'setup' ), 10, 2 );

All you would need to implement is the get_ical() method.
