Preventing the User from selecting an invalid date in a drop down menu

[mankolele]

Hi all.

I am having a tough time trying to find a way I can use to make restrictions to drop dows for dates, like the following dates are invalid and cannot be allowed to select them, April 31,June 31, September 31, November 31 and february 29 if not leap year.

How can I put a script for the dates.

Thank you nin advance.

Try to generate dates using the function mktime. I am listing an example...
[code=php]
<?php
$dateValue = '2007-01-01'; // start date
for($i=1;$i<60; $i++){ // will print 60 days from the start date
$pieces = explode('-',$dateValue);
$dateValue=date ("Y-m-j", mktime(0, 0, 0, date($pieces[1]), date($pieces[2])+1,date($piece s[0]))); // get next date
echo $dateValue;
echo "<br>";
}
?>
[/code]

The best way to solve this is by using javascript

you can either allow the user to input a date string and parse it with regexp like mm-dd-yyyy (the validation can be done with either javascript or PHP)

OR

you can make selectboxes for date, month, year (and hour&minute if you want)

according to which year & month is selected, theres 28,29,30 or 31 dates to choose from.

After submit you collect the actual date with mktime
