<?PHP
if($_GET['position_id']!=''&&$_GET['function']=='edit'){
	$_re = mysql_query("SELECT * FROM position WHERE position_id = ".$_GET['position_id']." ") or die(mysql_error());

}
else
if($_GET['position_id']!=''&&$_GET['function']=='delete'){
	mysql_query("DELETE FROM position WHERE position_id = ".$_GET['position_id']." ");
}
?>
