Linking Calendar Dates: Simple Example

This example simply provides a link for the first day of each month. If the day passed in is "1", then an appropriate link is returned. If it is any other value, an empty string is returned signifying "no link".
class MyCalendar extends Calendar { function getDateLink($day, $month, $year) { // Only link the first day of every month $link = ""; if ($day == 1) { $link = "first.php"; } return $link; } }
And the resulting calendar looks like this:
