    Extending Event Calendar Link to this post

    I am extending event_calendar, so class Seminar extends Calendar and SeminarEvent extends CalendarEvent and SeminarDateTime Extends CalendarDateTime

    So, SeminarDateTime contains plenty of fields like Location, Speaker, ....

    at this moment what I achieved is far better than what I managed before

    http://weyl.math.toronto.edu:8888/testsite/seminars

    and there are some problems. At this moment the most serious one:

    If I try to filter event not (only) by date but by "Category" (SeminarName) it returns an error

    [Warning] Unknown class passed as parameter
    GET /testsite/seminars/2009-11-19/2009-11-19?filter=1&filter_SeminarName=Applied+Math%2FPDE%2FAnalysis

    Line 471 in /Applications/MAMP/htdocs/testsite/event_calendar/code/Calendar.php

    ource

    462                $parts = explode(".",$db_field);
    463                $table = $parts[0];
    464                $field = $parts[1];
    465                $db_field = "`".$table."`.".$field;
    466             }
    467             else {
    468                $table = $db_field;
    469                $db_field = "`".$table."`";
    470             }
    471 if($table == "CalendarEvent" || is_subclass_of($table, "CalendarEvent"))
    472 $event_filters[] = $table;
    473 else if($table == "CalendarDateTime" || is_subclass_of($table, "CalendarDateTime"))
    474 $datetime_filters[] = $table;
    475             $for_db[] = "$db_field = '$value'";
    476          }
    477          return array($for_db, $event_filters, $datetime_filters);

    {color=blue]Any suggestions what I am doing wrong? (except trying to create this being (bloody) amateur - but everybody else in the Department is completely clueless )

    Lesser problems:

    1) in

    http://weyl.math.toronto.edu:8888/testsite/applied-math-pde-analysis/

    (etc) Last event date is lost

    2) In

    http://weyl.math.toronto.edu:8888/testsite/applied-math-pde-analysis/2009-11-20

    (etc) footer is lost

    but those are related with ss

    Thank in advance for advice

    This is a little glitch in the way the event calendar works. Remember, the objects that get fed to the calendar are DateTime objects, so if you're going to filter by a field that exists on the Event object, you need to specify that. Change the name of your filter field to "SeminarEvent_Category", and you should be good.
