162 CHAPTER 4 ■ BUILD AN EVENTS CALENDAR } ?> } */ if ( isset($event[0]) ) { return new Event($event[0]); } else { return NULL; } When called, this method will return an object (for the ID of 1) that looks like this: Event Object ( [id] => 1 [title] => New Year's Day [description] => Happy New Year! [start] => 2010-01-01 00:00:00 [end] => 2010-01-01 23:59:59 ) Creating a Method to Generate Markup Now that an array of a single event’s data is available, you can build a new public method to format the event data into HTML markup. This method will be called displayEvent(); it will accept an event’s ID and generate HTML markup using the following steps:
private $_daysInMonth; private $_startDay; public function __construct($dbo=NULL, $useDate=NULL) {...} public function buildCalendar() {...} /** * Displays a given event's information * * @param int $id the event ID * @return string basic markup to display the event info */ public function displayEvent($id) { /* * Make sure an ID was passed */ if ( empty($id) ) { return NULL; } } /* * Make sure the ID is an integer */ $id = preg_replace('/[^0-9]/', '', $id); /* * Load the event data from the DB */ $event = $this->_loadEventById($id); /* * Generate strings for the date, start, and end time */ $ts = strtotime($event->start); $date = date('F d, Y', $ts); $start = date('g:ia', $ts); $end = date('g:ia', strtotime($event->end)); /* * Generate and return the markup */ return "$event->title" . "\n\t$date, $start—$end" . "\n\t$event->description"; private function _loadEventData($id=NULL) {...} CHAPTER 4 ■ BUILD AN EVENTS CALENDAR 163
