Having problems with clean_gpc function

[Jaxel]

I am using the following code...

function update_event($event)
{
	global $vbulletin, $db;

	$venue	= htmlspecialchars($vbulletin->input->clean_gpc('p', 'venue', TYPE_STR));
	$name		= htmlspecialchars($vbulletin->input->clean_gpc('p', 'name', TYPE_STR));
	$split	= htmlspecialchars($vbulletin->input->clean_gpc('p', 'split', TYPE_UINT));
	$game		= htmlspecialchars($vbulletin->input->clean_gpc('p', 'game', TYPE_UINT));
	$category	= htmlspecialchars($vbulletin->input->clean_gpc('p', 'category', TYPE_UINT));

	$day		= htmlspecialchars($vbulletin->input->clean_gpc('p', 'day', TYPE_UINT));
	$month	= htmlspecialchars($vbulletin->input->clean_gpc('p', 'month', TYPE_STR));
	$year		= htmlspecialchars($vbulletin->input->clean_gpc('p', 'year', TYPE_UINT));
	$time		= htmlspecialchars($vbulletin->input->clean_gpc('p', 'time', TYPE_STR));
	$timestamp = $day." ".$month." ".$year." ".$time." ".date('T');

	$db->query_write("UPDATE rank_events SET gameID='".$game."' WHERE eventID='".$event['eventID']."'");
	$db->query_write("UPDATE rank_events SET categoryID='".$category."' WHERE eventID='".$event['eventID']."'");
	$db->query_write("UPDATE rank_events SET eDate='".strtotime($timestamp)."' WHERE eventID='".$event['eventID']."'");
	$db->query_write("UPDATE rank_events SET eVenue='".$venue."' WHERE eventID='".$event['eventID']."'");
	$db->query_write("UPDATE rank_events SET eName='".$name."' WHERE eventID='".$event['eventID']."'");
	$db->query_write("UPDATE rank_events SET eSplit='".$split."' WHERE eventID='".$event['eventID']."'");
}

I thought this code would "sanitize" my inputs so that I wouldn't have any poisoning going on... but I still get the following error when I try to input something with a ' in it...

Database error in vBulletin 3.8.1:

Invalid SQL:
UPDATE rank_events SET eVenue='Gamer's Edge' WHERE eventID='4';

MySQL Error   : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 's Edge' WHERE eventID='4'' at line 1
Error Number  : 1064

How do I fix this?
