So I take it you didn't write the code.

 

1) how to use this function in html form???

 

<form action="" method="post">
<?php make_calendar_pulldowns2() ?> 
</form>

 

2)  how to validate it, i.e avoid from unavailable date, leap year etc.......

 

<?php
if(checkdate($_POST['year2'] . "-" . $_POST['month2'] . "-" . $_POST['day2'])) {
  echo "Valid";
}
?>

 

3) i need to send its value in data base and when i press submit the vlaue should not reset

 

Change part 1 to the following will stop the values reseting on submit.

 

<form action="" method="post">
<?php make_calendar_pulldowns2($_POST['month2'], $_POST['day2'], $_POST['year2']) ?> 
</form>

 

As far as adding to the database, depends what database your using, the structure, etc, etc, etc.
