Explanation / Answer
table.calendar { border-left:1px solid #999; }
tr.calendar-row { }
td.calendar-day { min-height:80px; font-size:11px; position:relative; } * html div.calendar-day { height:80px; }
td.calendar-day:hover { background:#eceff5; }
td.calendar-day-np { background:#eee; min-height:80px; } * html div.calendar-day-np { height:80px; }
td.calendar-day-head { background:#ccc; font-weight:bold; text-align:center; width:120px; padding:5px; border-bottom:1px solid #999; border-top:1px solid #999; border-right:1px solid #999; }
div.day-number { background:#999; padding:5px; color:#fff; font-weight:bold; float:right; margin:-5px -5px 0 0; width:20px; text-align:center; }
/* shared */
td.calendar-day, td.calendar-day-np { width:120px; padding:5px; border-bottom:1px solid #999; border-right:1px solid #999; }
The PHP
copy/* draws a calendar */
function draw_calendar($month,$year){
/* draw table */
$calendar = '<table cellpadding="0" cellspacing="0" class="calendar">';
/* table headings */
$headings = array('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday');
$calendar.= '<tr class="calendar-row"><td class="calendar-day-head">'.implode('</td><td class="calendar-day-head">',$headings).'</td></tr>';
/* days and weeks vars now ... */
$running_day = date('w',mktime(0,0,0,$month,1,$year));
$days_in_month = date('t',mktime(0,0,0,$month,1,$year));
$days_in_this_week = 1;
$day_counter = 0;
$dates_array = array();
/* row for week one */
$calendar.= '<tr class="calendar-row">';
/* print "blank" days until the first of the current week */
for($x = 0; $x < $running_day; $x++):
$calendar.= '<td class="calendar-day-np"> </td>';
$days_in_this_week++;
endfor;
/* keep going with days.... */
for($list_day = 1; $list_day <= $days_in_month; $list_day++):
$calendar.= '<td class="calendar-day">';
/* add in the day number */
$calendar.= '<div class="day-number">'.$list_day.'</div>';
/** QUERY THE DATABASE FOR AN ENTRY FOR THIS DAY !! IF MATCHES FOUND, PRINT THEM !! **/
$calendar.= str_repeat('<p> </p>',2);
$calendar.= '</td>';
if($running_day == 6):
$calendar.= '</tr>';
if(($day_counter+1) != $days_in_month):
$calendar.= '<tr class="calendar-row">';
endif;
$running_day = -1;
$days_in_this_week = 0;
endif;
$days_in_this_week++; $running_day++; $day_counter++;
endfor;
/* finish the rest of the days in the week */
if($days_in_this_week < 8):
for($x = 1; $x <= (8 - $days_in_this_week); $x++):
$calendar.= '<td class="calendar-day-np"> </td>';
endfor;
endif;
/* final row */
$calendar.= '</tr>';
/* end the table */
$calendar.= '</table>';
/* all done, return result */
return $calendar;
}
/* sample usages */
echo '<h2>July 2009</h2>';
echo draw_calendar(7,2009);
echo '<h2>August 2009</h2>';
echo draw_calendar(8,2009);
The PHP is largely based upon one function that only requires the month and year of the calendar you'd like. It's a sizeable function but obviously worth its weight in gold. Also note that I've identified a spot within the calendar where you should query the database to see if there are any events for that day. I use tables because they nicely stretch when one day in the week is longer than others. Working with absolute positioning and DIVs in the calendar is far too much hassle for a simple calendar.
