Methods
public function isValid ($value)
Validates a date value.
Parameters
-
$value
Date value in one of the following formats:
- string matching pattern “yyyy-mm-dd”; e.g., “2000-12-31”.
- array with the following keys:
- 'year': positive integer greater than 0;
- 'month': positive integer from 1 to 12;
- 'day': positive integer greater than 0 and not greater than the number of days in the specified 'month' key; or simply greater than 0 if no month is specified.
Example
$validator = new waDateValidator(); // false if today is December 30, 2000 because specified date is compared with the current date wa_dumpc($validator->isValid('2000-12-31')); // true because "February 31" formally looks correctly and such a date is automatically converted to "March 2" wa_dumpc($validator->isValid('2000-02-31')); // false because no month can contain more than 31 days wa_dumpc($validator->isValid('2000-02-32')); // true wa_dumpc($validator->isValid([ 'year' => 2000, 'month' => 2, 'day' => 29, ], false));
public function isEmpty ($value)
Checks whether a specified date value is empty. Returns true
in the following cases:
$value
contains an empty string ornull
;$value
contains an array in which none of keys 'year', 'month' or 'day' contains a non-empty value.
Parameters

$value
Date value in any format.
Example
$validator = new waDateValidator(); // true wa_dumpc($validator->isEmpty('')); // true wa_dumpc($validator->isEmpty(null)); // true wa_dumpc($validator->isEmpty([])); // false wa_dumpc($validator->isEmpty([ 'year' => 2000, ])); // false wa_dumpc($validator->isEmpty([ 'year' => 2000, 'month' => 2, 'day' => 29, ]));
