Help Me With Php The Checks Start Date And End Date

[zamzam]

Hello,
May someone help me with a a php script or date calander that will enable users of the form to pick or select the start and end date. The start date should be equal to the current or future date and end date should be equal to start date or future date.
Have come have scripts below but is not working properly.
The date is being picked or selected using javascript calander, when I submit it gives error.
The script is as follows,

$tDepartureDatett =$_POST["Departure_Date"];//start date
$tReturnDatett =$_POST["Return_Date"];// end date

$tDepartureDate=date("$tDepartureDatett");
$tReturnDate=date("$tReturnDatett");

$testDate=(($tDepartureDate>=$dtoday) and($tReturnDate>=$tDepartureDate));

if($testDate==0){
echo"Check the Dates";
echo "<br>";
echo "<br>";
echo"Departure Date must be today or future date";
echo "<br>";
echo "<br>";
echo"Return Date must be equal to Departure Date or greater";
echo "<br>";
echo "<br>";
echo "<a href=javascript:history.Back()>Back</a>";
exit;
}
elese {

It does want I want

}

Date format is YYYY-MM-DD e.g 2006-09-1



Iam receiving this error


Warning: mktime() [function.mktime]: Windows does not support negative values for this function in c:\local\wamp\www\subsistence\test888.php on line 44

What is the actual format of the date information in the $_POST variables?

[zamzam]

Date format is YYYY-MM-DD e.g 2006-09-1

If strtotime (http://php.net/strtotime) doesn't do what you want, you can split the string with explode() (http://php.net/explode) to give you
$split[0] = year
$split[1] = month
$split[2] = day
After that, you can convert to unix time (for comparisons) with mktime() (http://php.net/mktime)
