[Php-calendar-discussion] Color for today's date, for holidays

[Larry J. <joh...@gm...>]

All. In the past as a result of some great help from Gabriel Harrison I was
able to set a special color for today's date.  I also added in a special
color for holidays.  Below is the code.  Enjoy!

#1 - In 'display.php' put in code like this:
...
// displays the day of the week and the following days of the week
// return XHTML data for the days
function display_days($day_count, $week_of_month, $month, $year)
{
    global $db, $phpc_script, $config, $first_day_of_week;

    if($day_count > 7) return array();

    $day_of_month = ($week_of_month - 1) * 7 + $day_count
        - ((7 + day_of_first($month, $year) - $first_day_of_week) % 7);

    if($day_of_month <= 0 || $day_of_month > days_in_month($month, $year)) {
        $html_day = tag('td', attributes('class="none"'));
    } else {
        $currentday = date('j');
        $currentmonth = date('n');
        $currentyear = date('Y');

    // set whether the date is in the past or future/present
    if ($month < 10) {
      $month2 = "0". $month;
    }
    else {
      $month2 = $month;
    }
    if ($day_of_month < 10) {
      $day_of_month2 = "0". $day_of_month;
    }
    else {
      $day_of_month2 = $day_of_month;
    }
    $curr_date = $year . "-" . $month2 . "-" . $day_of_month2;
    mysql_connect("localhost", "-----", "-----");
    mysql_select_db("calendar");
    $result = mysql_query("SELECT * FROM phpc_holidays
                           WHERE Holiday_Date = '". $curr_date . "'")
      or die('Could not look up holiday information; '  . mysql_error());
    //echo $result;
    if ($row = mysql_fetch_array($result)) {
      $holiday = "Yes";
    }
    else {
      $holiday = "No";
    }
    if($currentyear == $year && $currentmonth == $month && $currentday ==
$day_of_month) {
      $current_era = 'today';
    } elseif($holiday == "Yes") {
      $current_era = 'holiday';
    } elseif($currentyear > $year || $currentyear == $year
        && ($currentmonth > $month
          || $currentmonth == $month
          && $currentday > $day_of_month
           )) {
      $current_era = 'past';
    } else {
      $current_era = 'future';
    }

                if(can_add_event()) {
                $html_day = tag('td', attributes('valign="top"',
                                                "class=\"$current_era\""),
                                        create_date_link('+', 'event_form',
                                                $year, $month,
                                                $day_of_month,
                                                array('class="phpc-add"')),
                                        create_date_link($day_of_month,
                                                'display', $year, $month,
                                                $day_of_month,
                                                array('class="date"')));
                } else {
                $html_day = tag('td', attributes('valign="top"',
                                                "class=\"$current_era\""),
                                        create_date_link($day_of_month,
                                                'display', $year, $month,
                                                $day_of_month,
                                                array('class="date"')));
                }

        $result = get_events_by_date($day_of_month, $month, $year);
...

#2 - In 'style.php' put in code like this:
#2a - At the top:
...
$bgtoday = BG_TODAY;
$bgholiday = BG_HOLIDAY;
$bgpast = BG_PAST;
$bgfuture = BG_FUTURE;
...

Note that these colors were set in 'index.php' just like the other colors:
...
define('BG_TODAY',     '#00CED1');       // color for today's date
define('BG_HOLIDAY',   '#DA70D6');       // holiday's date
define('BG_PAST',      '#EEE8AA');       // past days, days already passed;
default = silver
define('BG_FUTURE',    '#EEE8AA');       // future days; default = white
...

#2b - Near the bottom:
...
#calendar {
  table-layout: fixed;
}

#calendar td {
  text-align: left;
  height: 80px;
  overflow: hidden;
}

td.past {
  background-color: <?php echo $bgpast ?>;
  color: inherit;
}

td.today {
  background-color: <?php echo $bgtoday ?>;
  color: inherit;
}

td.holiday {
  background-color: <?php echo $bgholiday ?>;
  color: inherit;
}

td.future {
  background-color: <?php echo $bgfuture ?>;
  color: inherit;
}

td.none {
  background-color: <?php echo $bgcolor2 ?>;
  color: inherit;
}

table.phpc-main ul {
  margin: 2px;
  padding: 0;
  list-style-type: none;
  border-color: <?php echo $sepcolor ?>;
  border-style: solid;
  border-width: 1px 1px 0 1px;
  background-color: <?php echo $bgcolore ?>;
}
....
