Date validation

by **sansoft** » Sat May 15, 2004 8:26 pm

Hi all,

i have got two DROPDOWN boxes one for Startdate and other for EndDate.
i have prepared a file datefunct.php which contains three functions getmonth,getyear,getday....i am calling these functions at an appropriate place.

Now i want to validate the dates ie startdate< enddate.upto this time the code does not validate anything..u can fill up anything u wish.

the select names(for the dropdowns ) for the three functions are "month","year","day".

How should i accomplish it?
plz help

Please see this!
I´m almost sure if your dates are in the same format, you can make a normal comparison, i mean like you said: startdate < enddate.

Example (This works):

Code: Select all: <?php $today = date("Y-m-d", mktime(0, 0, 0, date("m"), date("d"), date("Y"))); // The same format we´ve made above! $date_to_compar = '2004-05-13'; if($today > $date_to_compar){ echo $today . ' is greater than ' . $date_to_compar; }else{ echo $today . ' is less than ' . $date_to_compar; } ?>

Well you better stop by google. You´ll find some great examples!

Here is a lil´example.
I´m not a pro in javascript, so this isn´t the right way to do this.
It works anyway:

Code: Select all: <html> <head> <script> function compar(){ date1 = new Date(2004, 11, 15); date2 = new Date(2004, 11, 11); with(document){ write('<pre>'); if(date1 > date2){ writeln(date1 + ' (is greater than) ' + date2); }else{ writeln(date1 + ' (is less than) ' + date2); } write('<pre>'); } } </script> </head> <body> <table> <tr> <a href="javascript:compar()">compar it!</a></td> </tr> </table> </body> </html>

I have a solution for date validation, but before I make an assumption of what it is u really trying to achieve I must ask two questions.

1. Will the start and end dates be inserted into a database?
2. What format are you using in your drop down boxes....
i.e 14/06/2004
14-06-2004
14-Jun-2004

If on the other hand you just want to compare start and end date boxes against each other or the system time then the snippet code that [/b]gesf supplied seem OK.

Let us know.....
