Event Duration

Further to this. Initially I created a custom attribute but if certain criteria caused the length to change I’d have to change the finish time any way so wanted to automate. Plus I have no coding experience so its good to have a go to get an understanding, I bodged it together from the web, but it works.

Using the start and finish times of your event I created a shortcode to show event duration in XhY.

Hope it helps someone else.

function em_event_duration(){    
	$day = 0; $hour = 0; $minute = 0;
    $date1 = do_shortcode("[event]#_{Y-m-d H:i}[/event]"); 
    $date2 = do_shortcode("[event]#@_{Y-m-d H:i}[/event]"); 
    $datetimeObj1 = new DateTime($date1);
    $datetimeObj2 = new DateTime($date2);
    $interval = $datetimeObj1->diff($datetimeObj2);
    if($interval->format('%d') > 0){
    $day = $interval->format('%d')*24;
    }
    if($interval->format('%h') > 0){
    $hour = $interval->format('%h');
    }
    if($interval->format('%I') > 0){
    $minute = $interval->format('%I');
    }    
	return ($day + $hour) . "h" . $minute;	
}
add_shortcode ( 'ev-dur', 'em_event_duration' );
