Help me please

[kyyote]

I am a rank amateur.  Everything was going along fine.  Then I don't know what happened.  My home page is fine.  But, when I click the forum button I get this now;
Fatal error: Cannot redeclare toggleattend() (previously declared in /home/kyyotesd/public_html/Forum/Sources/Calendar.php:498) in /home/kyyotesd/public_html/Forum/Sources/Calendar.php on line 745


I have a back-up of my smf but don't know how to re-install it either. 

[Fizzy]

Have you installed Jacks Phat Calendar? If so it looks like you have installed it twice

[kyyote]

I have uninstalled it.  It remains the same.

[Fizzy]

Can you check your Sources/Calendar.php file at that line number and see if you have duplicated code

[kyyote]

This is what is there;

function ToggleAttend()
{
   global $ID_MEMBER, $user_info, $db_prefix, $board, $topic, $modSettings, $options;

   if ($user_info['is_guest'])
      fatal_lang_error(138, false);

   if (!allowedTo('calendar_view'))
      fatal_lang_error(1, false);

   if (empty($modSettings['cal_enabled']) || empty($modSettings['enable_attendees']))
      fatal_lang_error('calendar_off', false);

   $request = db_query("
      SELECT id_event, attendees
      FROM {$db_prefix}calendar
      WHERE id_board = $board
         AND id_topic = $topic
      LIMIT 1", __FILE__, __LINE__);

   $attendeeinfo = mysql_fetch_assoc($request);

   if ($attendeeinfo['id_event'] != '')
   {
      $attendees = explode(',', $attendeeinfo['attendees']);
      if (in_array("$ID_MEMBER", $attendees))
      {
         $thisArray[] = $ID_MEMBER;
         $attendees = array_diff($attendees, $thisArray);
      }
      else
         $attendees[] = $ID_MEMBER;

      $attendees = implode(",", array_unique($attendees));
      if (substr($attendees,0,1) == ',')
         $attendees = substr($attendees,1);

      $request = db_query("
         UPDATE {$db_prefix}calendar
         SET attendees='$attendees'
         WHERE id_board = $board
            AND id_topic = $topic
         LIMIT 1", __FILE__, __LINE__);
   }
   redirectexit($_SERVER['HTTP_REFERER'], false);
}

[Fizzy]

Thanks for that

As there are two error lines can you post a copy of your whole file?

[kyyote]

I'm sorry.  As I said, I am clueless.

/*   This file has only one real task... showing the calendar.  Posting is done
   in Post.php - this just has the following functions:

   void CalendarMain()
      - loads the specified month's events, holidays, and birthdays.
      - requires the calendar_view permission.
      - depends on the cal_enabled setting, and many of the other cal_
        settings.
      - uses the calendar_start_day theme option. (Monday/Sunday)
      - uses the main sub template in the Calendar template.
      - goes to the month and year passed in 'month' and 'year' by
        get or post.
      - accessed through ?action=calendar.

   array calendarBirthdayArray(string earliest_date, string latest_date)
      - finds all the birthdays in the specified range of days.
      - earliest_date and latest_date are inclusive, and should both be in
        the YYYY-MM-DD format.
      - works with birthdays set for no year, or any other year, and
        respects month and year boundaries.
      - returns an array of days, each of which an array of birthday
        information for the context.

   array calendarEventArray(string earliest_date, string latest_date,
         bool use_permissions = true)
      - finds all the posted calendar events within a date range.
      - both the earliest_date and latest_date should be in the standard
        YYYY-MM-DD format.
      - censors the posted event titles.
      - uses the current user's permissions if use_permissions is true,
        otherwise it does nothing "permission specific".
      - returns an array of contextual information if use_permissions is
        true, and an array of the data needed to build that otherwise.

   array calendarHolidayArray(string earliest_date, string latest_date)
      - finds all the applicable holidays for the specified date range.
      - earliest_date and latest_date should be YYYY-MM-DD.
      - returns an array of days, which are all arrays of holiday names.

   void calendarInsertEvent(int id_board, int id_topic, string title,
         int id_member, int month, int day, int year, int span)
      - inserts the passed event information into the calendar table.
      - recaches the calendar information after doing so.
      - expects the passed title not to have html characters.
      - handles spanned events by inserting them multiple times.
      - does not check any permissions of any sort.

   bool calendarCanLink()
      - checks if the current user can link the current topic to the
        calendar, permissions et al.
      - this requires the calendar_post permission, a forum moderator, or a
        topic starter.
      - expects the $topic and $board variables to be set.
      - returns true or false corresponding to whether they can or cannot
        link this topic to the calendar.
