Я создаю календарь PHP, который связан с базой данных, содержащей список дат. Мне удалось создать календарь, подключиться к базе данных и отобразить даты. Однако вместо простого изменения класса, если дата найдена в базе данных, я получаю повторяющиеся даты.события отображения в календаре php
Мой код PHP:
<?php
/* program name: Build Calender */
/* description: build calender */
/* 1 -> build table */
/* 2 -> add headings */
/* 3 -> add blanks */
/* 4 -> connect to db */
/* 5 -> check if dates in db = dates in calendar */
/* 6 -> td with diff id */
/* 7 -> add remaining blanks */
$month = (int) (isset($_GET['month']) ? $_GET['month'] : date('m'));
$year = (int) (isset($_GET['year']) ? $_GET['year'] : date('Y'));
echo "<h1 style='float:left; padding-right:30px;'>".date("F",mktime(0,0,0,$month,1,$year))." ".$year."</h1>";
$next = '<a href="?month='.($month != 12 ? $month + 1 : 1).'&year='.($month != 12 ? $year : $year + 1).'" class="control">Next</a>';
/* "previous month" control */
$previous = '<a href="?month='.($month != 1 ? $month - 1 : 12).'&year='.($month != 1 ? $year : $year - 1).'" class="control">Previous </a>';
$controls = $previous."|".$next;
echo $controls;
$headings = array(0 =>'mon','tue','wed','thurs','fri','sat','sun');
$running_day = date('w',mktime(0,0,0,$month,0,$year));
$days_in_month = date('t',mktime(0,0,0,$month,1,$year));
$days_in_this_week = 1;
$day_counter = 1;
$dates_array = array();
$gourmet_type = "";
echo"<table border='1px'>\n";
for ($weeks = 0; $weeks<= 5 ; $weeks++)
{
echo "<tr>\n";
for ($days = 0; $days <= 6 ; $days++)
{
if($weeks == 0)
{
echo"<td>".$headings[$days]."</td>\n";
}
else if ($weeks == 1 && $days < $running_day) //Generates first row
{
echo "<td class='day-cell'>"."yy"."</td>\n";
}
else if ($day_counter <= $days_in_month) //Adds the rest of the days
{
// varialbes for day-cell //
$available = "<td class='day-cell available' id='$day_counter'>".$day_counter."</td>\n";
$lunch = "<td class='day-cell lunch' id='$day_counter'>".$day_counter."</td>\n";

/** QUERY THE DATABASE FOR AN ENTRY FOR THIS DAY !! IF MATCHES FOUND, PRINT THEM !! **/
$db_link = mysql_connect("$host", "$user", "$password") or die('Cannot connect');
mysql_select_db("$database",$db_link) or die('Cannot select the DB');
$query = "SELECT * FROM reservations";
$result = mysql_query($query,$db_link) or die('cannot get results!');
while($row = mysql_fetch_assoc($result))
{
if ($row['date_of_reservation'] == $datestring && $row['reservationType'] == "LUNCH")
