INSERT problem

Could someone take a look at this code and help pinpoint the issue? I can view the data but am unable to "add" or "edit" the data.

What happens when you try to add an event ?

Interestingly enough, nothing. ;) I receive no errors, nor is anything added to the DB.

BTW...I love your tutorials!

Here are the functions
<?php
function add_event($title, $contents, $date, $time){
	$title 			= mysql_real_escape_string		($title);
	$location 		= mysql_real_escape_string		($location);
	$date 			= mysql_real_escape_string		($date);
	$time 			= mysql_real_escape_string		($time);
	
	mysql_query("INSERT INTO `events` SET 
					`id` 			= {$id},
					`title` 		= '{$title}',
					`location` 		= '{$location}',
					`date`			= '{$date}',
					`time`			= '{$time}'");
}

function edit_event($id, $title, $contents, $date, $time){
	$id				=(int) 							$id;
	$title 			= mysql_real_escape_string		($title);
	$location 		= mysql_real_escape_string		($location);
	$date 			= mysql_real_escape_string		($date);
	$time 			= mysql_real_escape_string		($time);	
	
	mysql_query("UPDATE `events` SET
					`id` 			= {$id},
					`title` 		= '{$title}',
					`location` 		= '{$location}',
					`date`			= '{$date}',
					`time`			= '{$time}'
				WHERE `id` = {$id}");
}

function delete($table, $id){
	$table = mysql_real_escape_string($table);
	$id = (int)$id;
	mysql_query("DELETE FROM `{$table}` WHERE `id` = {$id}");
}

function get_events($id = null){
	$events = array();
	
	$query = 	"SELECT `events`.`id` AS `post_id`,
						`title`, `location`, `date`, `time`
				FROM `events`";
				
	if ( isset($id)) {
		$id = (int) $id;
		$query .= " WHERE `events`.`id` = {$id}";
	}
	
	$query .= " ORDER BY `events`.`id` DESC" or die();
				
	$query = mysql_query($query);
	
	while( $row = mysql_fetch_assoc($query)) {
		$events[] = $row;
	}
	
	return $events;
}
?>

Try adding
echo mysql_error();
after what ever query is failing and see if that tells you what is wrong.
