function getCity($provinceId)
    {
        $sql ="SELECT `cityid`,`cityname` FROM `tblcity` inner join `tblprovince` ON `tblcity`.`pid`='$provinceId'  order by `cityid` asc";
        $query = mysql_query($sql) or die ("Could not access DB: " . mysql_error());
			$row = mysql_fetch_assoc($query);		
			while($row)
			{
			$id = $row['cityid'];
			$name = $row['cityname'];
			echo 
			"
				<option value ='$id'>".$name."</option>
			";  
			$row = mysql_fetch_assoc($query);
		   }
     }

The option should be inside select element, which should be inside form element. Is it so?
You can access form values from $_GET or $_POST php predefined variables.
