Drop down input for dates

Hi All,

I want to make a drop down box (rather 3) for date. month and year. I heard from the forums that there is no ready made function available to do that. After searching, I got a script from the phpclasses forum which goes like this:

#####

<?php
class DateDDLGenerator{

var $intYear;
var $intMonth;
var $intDay;
var $bolSetToCurrentDay;

function DateDDLGenerator(){
$this->bolSetToday = false;
$this->intYear = date(“Y”);
$this->intMonth = date(“m”);
$this->intDay = date(“d”);
}

function setToCurrentDay(){
$this->bolSetToCurrentDay = true;
}

#Generate Year range
function genYearDDL($selName = ‘Year’, $yearCount = 50, $year = ”){
/*
Check if the year passed in is the same as current year.
If the year got is not given or same as current year, the list
will select the current year by default. Otherwise, $yearSelect
will be set to what user entered.
*/
$yearSelect = $year == ” ? date(“Y”) : $year;

/*
$yearCount: it is the length of your drop down list, i.e. how many
years do you want to show. It is 50 by default, which shows 50 years
from now.
*/

$str = “<select name=’$selName’>n”;
for($i = $yearSelect; $i >= ($yearSelect – $yearCount); $i–){
if($this->bolSetToCurrentDay == true){
$selected = $this->intYear == $i ? ‘selected=”selected”‘ : ”;
}
$str .= “t<option value=’$i’ $selected>$i</option>n”;
}
$str .= “</select>n”;
print $str;
}

#Generate month range from 1 to 12
function genMonthDDL($selName = ‘Month’, $date_format = ‘short’){
$shortM = array(1 => “Jan”, “Feb”, “Mar”,
“Apr”, “May”, “Jun”,
“Jul”, “Aug”, “Sep”,
“Oct”, “Nov”, “Dec”);

$longM = array(1 => “January”, “February”, “March”,
“April” , “May” , “June” ,
“July” , “Aug” , “September”,
“October”, “November”, “December”);

$str = “<select name=’$selName’>n”;
if($date_format == ‘short’){
for($i = 1; $i <= 12; $i++){
if($this->bolSetToCurrentDay == true){
$selected = $this->intMonth == $i ? ‘selected=”selected”‘ : ”;
}
$str .= “t<option value=’$i’ $selected>”.$shortM[$i].”</option>n”;
}
}elseif($date_format == ‘long’){
for($i = 1; $i <= 12; $i++){
if($this->bolSetToCurrentDay == true){
$selected = $this->intMonth == $i ? ‘selected=”selected”‘ : ”;
}
$str .= “t<option value=’$i’ $selected>”.$longM[$i].”</option>n”;
}
}
$str .= “</select>n”;

print $str;
}

#Generate day range from 1 to max days of relevant month
function genDayDDL($selName = ‘Day’){
$str = “<select name=’$selName’>n”;

//Thanks to Peter K on this improvement and now this method support leap year
if ($this->intMonth == 2) { // February ?
$leap_day = 0;

if ($this->intYear >= 4 && $this->intYear % 4 == 0) { // Leap year ?
if ($this->intYear >= 1800 && $this->intYear % 100 == 0) { // No accurate leap centuries before that
if (($this->intYear / 100) % 4 == 0)
$leap_day = 1;
} else
$leap_day = 1;
}

$max_days = 28 + $leap_day;
} else if ($this->intMonth == 4 || $this->intMonth == 6 ||
$this->intMonth == 9 || $this->intMonth == 11)
$max_days = 30;
else
$max_days = 31;

for($i = 1; $i <= $max_days; $i++){
if($this->bolSetToCurrentDay == true){
$selected = $this->intDay == $i ? ‘selected=”selected”‘ : ”;
}
$str .= “t<option value=’$i’ $selected>$i</option>n”;
}
$str .= “</select>n”;
print $str;
}

}
?>

They call it a class file and I don’t know how to use a class file in php. Can anyone help me please?

Thanks in advance.

With love, Anirban.
