Validation::date

Check date format

Description

public boolean Validation::date( string $name, mixed $value, [ mixed $code = '' ] )

The separators / and - are removed, then the value must be digits only: YYYY (a year), YYYYMM (a year and a month from 01 to 12) or YYYYMMDD (an existing date, checked with checkdate()). So 2024, 2024/04, 2024-04-01 and 20240401 are valid; 2024/4/1 is not (8 digits are required for a day).

An empty value ('', null, '0', whitespace only) is not checked and returns true: combine with Validation::required when the field is required. When $name already has an error, the check is skipped and returns false, so only the first error of each field is kept.

Arguments

Name	Data type	Default	Remarks
$name	string		Field name (key of the error message)
$value	mixed		Value to check
$code	mixed	''	Error code, array of error code and parameters, or error message (see Configuration)

Example

Controller

use Fegg\Validation;

$validation = new Validation();

$validation->date('success', '2024-04-01', array('@date', 'Date')); // -> true
$validation->date('failed', '2024-02-30', array('@date', 'Date')); // -> false

var_dump($validation->getErrorMessage());
// -> array('failed' => '<strong>Date</strong> の日付では登録できません')
