} ?> CHAPTER 5 ■ ADD CONTROLS TO CREATE, EDIT, AND DELETE EVENTS Modifying the Full Event Display Method to Show Admin Controls Before the Edit button will be displayed, the _adminEntryOptions() method needs to be called from within the displayEvent() method. This is as simple as storing the return value of _adminEntryOptions() in a variable, $admin, and outputting that variable along with the rest of the entry markup. Add the following bold modifications to displayEvent() in the Calendar class: /** * 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)); /* * Load admin options if the user is logged in */ $admin = $this->_adminEntryOptions($id); /* * Generate and return the markup */ return "$event->title" . "\n\t$date, $start—$end" 187
