When a user enters a date in text box,i've to check ,whether it is in yyyy-mm-dd format.
Note Even month,date,for eg:2012-02-32 is not valid because,date can be only till 31 and same for month,he can n't enter month as 13.
If it is in wrong format,i should echo.
Thanks in advance!
Try this
list($year,$month,$day) = explode('-', $input);
if (checkdate($month, $day, $year)) {
// Correct
} else {
// Incorrect
}
Reading comments on http://php.net/manual/en/function.checkdate.php is quite informative, including validating through regexp.
I use the following code from that page:
function checkDateTime($data) {
if (date('Y-m-d', strtotime($data)) == $data) {
return true;
} else {
return false;
}
}
Also I'd recommend adding JavaScript datepicker http://jqueryui.com/demos/datepicker/
$e = explode('-', '2012-02-32');
if (checkdate($e[1], $e[2], $e[0])){
// Valid
}else{
// Invalid
}
You should not use regular expressions for this. A better (maybe not the best) is to use checkdate();
$parts = explode('-', $input);
if (sizeof($parts) == 3 && checkdate($parts[1], $parts[2], $parts[0])) {
// Correct
} else {
// Incorrect
}
