Validation::alphameric

Check half-width alphanumeric characters

Description

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

Valid when the value contains only 0-9, a-z and A-Z.

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->alphameric('success', 'abc123', array('@alphameric', 'Code')); // -> true
$validation->alphameric('failed', 'abc-123', array('@alphameric', 'Code')); // -> false

var_dump($validation->getErrorMessage());
// -> array('failed' => '<strong>Code</strong> は半角英数で入力してください')
