Extending calendar functionality to accept years - php

Question

I'm working on an event scheduler site and I am currently stuck as I'm using a Months table (with id & month as the headers) to group my results by month. Due to this, if I try to schedule an event for January 2016, it successfully puts it into the month I choose as intended, but understandably puts it into 2015.
I'm looking to get some help on extending this beyond the end of the current year and adding functionality for different years.
I would happily use another method than using my current table setup, so any tips or suggestions would be appreciated.
Current code is as follows:
<?php include 'includes/connect.php';
include 'includes/header.php';
$curMonth = date("n"); ?>
<b>Upcoming Trip Information:</b><br><br>
<?php
$res = mysql_query("SELECT * FROM months ORDER BY id");
while ($rows = mysql_fetch_array($res)) {
if($rows['id'] >= $curMonth ){
$monthname = $rows['month']; ?>
<table cellpadding="0" cellspacing="3" width="100%">
<tr>
<td>
<?php
$tid = $_GET['transporter'];
$check = mysql_query("SELECT * FROM trips WHERE monthname(start_date) = '" . $rows['month'] . "' AND tid = '$tid'");
$check = mysql_num_rows($check);
if ($check < 1) {
echo "";
} else { ?> <h2><?php echo $monthname; ?><?php } ?></h2></td></tr> <tr> <?php $cmonth = date('F');
$tid = $_GET['transporter'];
$res1 = mysql_query("SELECT * FROM trips WHERE monthname(start_date) = '$monthname' ORDER BY start_date");
while ($rows = mysql_fetch_array($res1)) {
$trid = $rows['trid'];
$trip_start = $rows['trip_start'];
$trip_end = $rows['trip_end'];
$start_date = $rows['start_date'];
$end_date = $rows['end_date'];
$colour = $rows['colour'];
$stime = strtotime($start_date);
$startt = date("l jS", $stime);
$etime = strtotime($end_date);
$endt = date("l jS", $etime); ?>
<td valign="middle" style="height: 100px; background-color: #4b99ed; text-align: center;">
<div style="font-size: 17px; color: #ffffff;"><?php echo $trip_start; ?> to <?php echo $trip_end; ?></div>
<div style="font-size: 15px; color: #ffffff;"><?php echo $startt; ?> - <?php echo $endt; ?></div>
</td>
<?php } } } ?>
</tr>
</table> <?php include 'includes/footer.php'; ?>
If possible I would like to maintain the results layout..

You could try, instead of using a months table, using the start_date column of your trips table.
Try changing your query:
SELECT trips.*, DATE_FORMAT('%M, %Y', start_date) as `dt`
FROM trips
WHERE tid = '$tid' /* This is bad, please prepare or escape your variables*/
ORDER BY `dt` ASC
You then won't have to do the first query to get all the months and loop through them. If you must have empty containers for each month, try using that query, but loop through a PHP-generated array of months to display.
