Question

I’d hate to reinvent the wheel on this one if it’s out there somewhere, but has anyone extended or modified the codigniter calendar to handle multi-day events and multiple events per day or is it there a module available somewhere?

Answer 1

This can be easily modified in the file system/libraries/Calendar.php with the following addition of code. I know that editing any system file is considered taboo, but this helped me out in my application a ton. Take note of the foreach() loop in the commented section that says //If more than one event on the same day. This is the code that needs to be added to the Calendar.php library file. This resource can be futher elaborated on at the following link.

Calendar.php modified code:

if (isset($data[$day]))
                    {
                        // Cells with content
                        $temp = ($is_current_month == TRUE AND $day == $cur_day) ? $this->temp['cal_cell_content_today'] : $this->temp['cal_cell_content'];

                        // If more than one event on the same day
                        if (is_array($data[$day]))
                        {
                          $several_events = '';
                          foreach ($data[$day] as $key => $value)
                          {
                            $several_events .= '<li id="'.$key.'">'.$value.'</li>';
                          }
                          $out .= str_replace('{day}', $day, str_replace('{content}', $several_events, $temp));
                        }

                        // One event per day
                        else
                        {
                          $out .= str_replace('{day}', $day, str_replace('{content}', $data[$day], $temp));
                        }
                    }
                    else
                    {
                        // Cells with no content
                        $temp = ($is_current_month == TRUE AND $day == $cur_day) ? $this->temp['cal_cell_no_content_today'] : $this->temp['cal_cell_no_content'];
                        $out .= str_replace('{day}', $day, $temp);
                    }
                }
                else
                {
                    // Blank cells
                    $out .= $this->temp['cal_cell_blank'];
                }

Keep in mind that I’ve shown more than just the edited code above to help you locate it within Calendar.php. I hope this helps!
