[SOLVED] Highlight Today in Calendar

[SkyRanger]

I am trying to figure out how I can highlight todays date in a calendar script.  Anybody have any ideas?

 

  function getEventDays($month, $year) { 
  $days = array(); 
  $sql = mysql_query("
  SELECT DAY(event_date) AS day, COUNT(event_id), event_title 
  FROM calendar_events 
  WHERE MONTH(event_date) = '$month' 
  AND YEAR(event_date) = '$year'
  GROUP BY day"); 



  if (mysql_num_rows($sql) > 0) { 
  while ($row = mysql_fetch_array($sql)) $days[] = $row['day']; 
  } 

  return $days; 
} 

function drawCalendar($month, $year) { 
  // set variables we will need to help with layouts 
  $first       = mktime(0,0,0,$month,1,$year); // timestamp for first of the month 
  $offset      = date('w', $first); // what day of the week we start counting on 
  $daysInMonth = date('t', $first); 
  $monthName   = date('F', $first); 
  $weekDays    = array('Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'); 
  $eventDays   = getEventDays($month, $year); 
  
  

  // Start drawing calendar 
  $out  = "<table  border=\"1\" id=\"myCalendar\">\n"; 
  $out .= "<tr><th colspan=\"7\">$monthName $year</th></tr>\n"; 
  $out .= "<tr>\n"; 
  foreach ($weekDays as $wd) $out .= "<td width=\"50\" class=\"weekDays\"><div align=\"center\">$wd</div></td>\n"; 
   
  $i = 0; 
  for ($d = (1 - $offset); $d <= $daysInMonth; $d++) { 
    if ($i % 7 == 0) $out .= "<tr>\n"; // Start new row 
    if ($d < 1) $out .= "<td class=\"nonMonthDay\"> </td>\n"; 
    else { 
      if (in_array($d, $eventDays)) { 
        $out .= "<td class=\"monthDay\">\n"; 
        $out .= "<a href=\"?year=$year&month=$month&day=$d\"><div align=\"center\">$d</div></a>\n"; 
        $out .= "</td>\n";
      } else $out .= "<td class=\"monthDay\"><div align=\"center\">$d</div></td>\n"; 
    } 
    ++$i; // Increment position counter 
    if ($i % 7 == 0) $out .= "</tr>\n"; // End row on the 7th day 
  } 
   
  // Round out last row if we don't have a full week 
  if ($i % 7 != 0) { 
    for ($j = 0; $j < (7 - ($i % 7)); $j++) { 
      $out .= "<td class=\"nonMonthDay\"> </td>\n"; 
    } 
    $out .= "</tr>\n"; 
  } 
   
  $out .= "</table>\n"; 
     
    return $out; 
} 

$year  = isset($_GET['year']) ? $_GET['year'] : date('Y'); 
$month = isset($_GET['month']) ? $_GET['month'] : date('m'); 
$day = isset($_GET['day']) ? $_GET['day'] : date('d');

echo drawCalendar($month, $year); 

// Previous month link
$prevMonth = date('F',strtotime("last month")); 
$prevTS = strtotime("$year-$month-01 -1 month"); // timestamp of the first of last month 
$pMax = date('t', $prevTS); 
$pDay = ($day > $pMax) ? $pMax : $day; 
list($y, $m) = explode('-', date('Y-m', $prevTS)); 
echo "<p>\n"; 
echo "<a href=\"?year=$y&month=$m&day=$pDay\">« $prevMonth</a> |\n";

// Next month link 
$nextMonth = date('F',strtotime("next month")); 
$nextTS = strtotime("$year-$month-01 +1 month"); 
$nMax = date('t', $nextTS); 
$nDay = ($day > $nMax) ? $nMax : $day; 
list($y, $m) = explode('-', date('Y-m', $nextTS)); 
echo "<a href=\"?year=$y&month=$m&day=$nDay\">$nextMonth »</a>\n"; 
echo "</p>\n"; 
?>
</div>

it seems you need to just do an if statement when displaying each date and in that statement use in_array() to see if the current date you are parsing is in the date array you are using to select your highlighted dates from

 

http://www.php.net/function.in-array

 

if(in_array($CurrentDate, $dateArray)){

  //highlight cell with <div> background color

}

You can add a new class in your CSS to display todays date as you would like to, then just modify your calendar printing code to check for printing out todays cell.

 

Change:

 

if (in_array($d, $eventDays)) { 
       $out .= "<td class=\"monthDay\">\n"; 
       $out .= "<a href=\"?year=$year&month=$month&day=$d\"><div align=\"center\">$d</div></a>\n"; 
       $out .= "</td>\n";
     } else $out .= "<td class=\"monthDay\"><div align=\"center\">$d</div></td>\n"; 

 

... to this:

 

// Set the current date and the date to be printed
// to compare them
$today = date("m-d-Y");
$current = $month."-".$d."-".$year;

// Check if the current day to be printed is today
if($today == $current){
	$td_class = "monthToday";
} else {
	$td_class = "monthDay";
}

if (in_array($d, $eventDays)) { 
	$out .= "<td class=\"".$td_class."\">\n"; 
	$out .= "<a href=\"?year=$year&month=$month&day=$d\"><div align=\"center\">$d</div></a>\n"; 
	$out .= "</td>\n";
} else $out .= "<td class=\"".$td_class."\"><div align=\"center\">$d</div></td>\n";
