Regular Expressions + Date Check

[obrienkev]

Hi all

How do I check that a date is entered in this format?
DD/MM/YYYY

Tried below so far...

$new_date = $_POST['new_date'];

ereg([0-9][0-9][/][0-1][0-9][/][2][0][0-9][0-9]);

Thanks.

You could try:

function isValidDate($date) {
	return preg_match('#^\d\d/\d\d/\d{4}$#', $date)
		&& checkdate(
			(int)substr($date, 3, 2),
			(int)substr($date, 0, 2),
			(int)substr($date, 7, 4));
}

For a better date validator have a look at the one I use http://www.stevenmapes.com/index.php?/archives/46-Date-Validation-Function.html

It accepts dates in ISO format, but with three different separators, and validates the format as well as the date itself

if (preg_match('/^\d{2}\/\d{2}\/\d{4}$/', $new_date)) {
echo "Ok";
} else {
echo "Error!";
}
