SQL Query only displaying first result rather than arrayed data - php

Question

Basically I am building a calendar page that displays the months, and the days of the month(pulled from my database) and then any days that are inside the "start_date - end_date" variables are displayed with a different cell background color to the days that don't have a start or end date assigned, I have it working to an extent but it's only displaying the earliest of each months record rather than all the results.
ie.
2015-03-12(start) - 2015-03-16(end)
2015-03-03(start) - 2015-03-10(end)
And rather than display like this...
`1 2 [3 4 5 6 7 8 9 10] 11 [12 13 14 15 16] 17 18 19 20 ...`
it's just showing the [3 - 10] record, here is my current code..
<table width="100%" cellspacing="0">
<?php
$cmonth = date('F');
$cyear = date('Y');
$sql = "SELECT * FROM calendar WHERE year = '$cyear' ORDER BY m_order ASC";
$res = mysql_query($sql);
while ($rows = mysql_fetch_array($res)) {
$month_end = $rows['days_in_month'];
$month_name = $rows['month_name'];
$m_order = $rows['m_order'];
$sql2 = "SELECT * FROM trips WHERE start_date LIKE '____-0$m_order-__' ORDER BY start_date ASC";
$res2 = mysql_query($sql2);
$row = mysql_fetch_assoc($res2);
$stdate = $row['start_date'];
$s = date_parse_from_format("Y-m-d", $stdate);
$endate = $row['end_date'];
$e = date_parse_from_format("Y-m-d", $endate);
$start = $s['day'];
$end = $e['day'];
?>
<tr>
<td width="80px"><?php echo $month_name; ?></td>
<?php
foreach(range(1, $month_end) as $days)
{
if(in_array($days, range($start, $end)))
{
echo "<td style=\"background-color: #ccc;\" align=\"center\">" . $days . " </td>";
}
else
echo "<td align=\"center\">" . $days . "</td>";
}
?>
</tr>
<?php } ?>
</table>
Also I am aware of the dangers not using mysqli but I am just learning this on my local machine and plan on researching updated strategies once I get the functions working, so I'll know if my functions are broken or my coding is.
Thanks

try with common function to read data from table
function db_set_recordset($sql) {
$qry = mysql_query($sql);
$row= array();
while($out = mysql_fetch_assoc($qry)) {
$row[] = $out;
}
return $row;
}
$cmonth = date('F');
$cyear = date('Y');
$sql = "SELECT * FROM calendar WHERE year = '$cyear' ORDER BY m_order ASC";
$res = mysql_query($sql);
while ($rows = mysql_fetch_array($res)) {
$month_end = $rows['days_in_month'];
$month_name = $rows['month_name'];
$m_order = $rows['m_order'];
$sql2 = "SELECT * FROM trips WHERE start_date LIKE '____-0$m_order-__' ORDER BY start_date ASC";
$res2 = mysql_query($sql2);
$row = db_set_recordset($res2);
$stdate = $row['start_date'];
$s = date_parse_from_format("Y-m-d", $stdate);
$endate = $row['end_date'];
$e = date_parse_from_format("Y-m-d", $endate);
$start = $s['day'];
$end = $e['day'];
?>
<tr>
<td width="80px"><?php echo $month_name; ?></td>
<?php
foreach(range(1, $month_end) as $days)
{
if(in_array($days, range($start, $end)))
{
echo "<td style=\"background-color: #ccc;\" align=\"center\">" . $days . " </td>";
}
else
echo "<td align=\"center\">" . $days . "</td>";
}
?>
</tr>
<?php } ?>
</table>

You are only fetching one row of your result set from your trips table. You need something like this to get the second one.
while ( $row = mysql_fetch_assoc($res2) ) {
/* process each row */
}
You're doing this right for your other result set. Take a look at the examples here: http://php.net/manual/en/function.mysql-fetch-assoc.php
You'll need to run through the result set rows and accumulate your "hot" days, then render the days just once. Something like this:
$sql2 = "SELECT * FROM trips WHERE start_date LIKE '____-0$m_order-__' ORDER BY start_date ASC";
$res2 = mysql_query($sql2);
while ($row = mysql_fetch_assoc($res2)) {
$stdate = $row['start_date'];
$s = date_parse_from_format("Y-m-d", $stdate);
$endate = $row['end_date'];
$e = date_parse_from_format("Y-m-d", $endate);
$start = $s['day'];
$end = $e['day'];
$hot_days = array();
foreach(range(1, $month_end) as $days) {
$hot_days[$days] = 0;
if(in_array($days, range($start, $end))) {
$hot_days[$days] ++;
}
}
}
/* now you have a $hot_days array with nonzero values for interesting days */
?>
<tr>
<td width="80px"><?php echo $month_name; ?></td>
<?php
foreach(range(1, $month_end) as $day) {
if($hot_days[$day] > 0) {
echo "<td style=\"background-color: #ccc;\" align=\"center\">" . $days . " </td>";
}
else {
echo "<td align=\"center\">" . $days . "</td>";
}
}
?>
</tr>
With respect, I don't have time to debug this.
