, (*2)
A result object for a validation function., (*3)
composer require jasny/validation-result
use Jasny\ValidationResult;
function validateVar($var)
{
if (isset($var)) return ValidationResult::error("var isn't set");
if ($var < 30) return ValidationResult::error("var is less than thirty");
return ValidationResult::success();
}
$validation = validateVar($myVar);
if ($validation->failed()) echo $validation->getError();
use Jasny\ValidationResult;
function validateInput($input)
{
$validation = new ValidationResult();
if (!isset($input['baz'])) $validation->addError("baz isn't set");
if (!isset($input['qux'])) $validation->addError("qux isn't set");
return $validation;
}
$validation = validateInput($_POST);
if ($validation->succeeded()) {
// Handle POST and redirect
exit();
}
loadTemplate('myTemplate', ['errors' => $validation->getErrors()]);
You can add the validation result of a subvalidation using the add() method. It's possible to prefix all the errors
of the subvalidation., (*4)
use Jasny\ValidationResult;
function validateInput($input)
{
$validation = new ValidationResult();
if (!isset($input['baz'])) $validation->addError("baz isn't set");
if (!isset($input['qux'])) $validation->addError("qux isn't set");
if (isset($input['foo'])) {
$fooValidation = validateFoo($input['foo']);
$validation->add($fooValidation, 'foo');
}
return $validation;
}
function validateFoo($foo)
{
$validation = new ValidationResult();
if (empty($foo['name'])) $validation->addError("name isn't set");
if (empty($foo['age'])) $validation->addError("age isn't set");
return $validation;
}
$validation = validateInput($_POST);
It's possible to translate the error messages using a callback., (*5)
use Jasny\ValidationResult;
$aliases = [
"%s isn't set" => 'Please set %s',
"%s is less than %d" => 'Please choose a value higher than %2$d for %1$s'
];
ValidationResult::$translate = function($message) use ($aliases) {
return isset($aliases[$message]) ? $aliases[$message] : $message;
};
function validateVar($var)
{
if (isset($var)) return ValidationResult::error("%s isn't set", 'Var');
if ($var < 30) return ValidationResult::error("%s is less than %d", 'Var', 30);
}
or simply, (*6)
ValidationResult::$translate = 'gettext';
