validateAll()

validateAll() runs the same centralized pipeline as validate() but returns every applicable ValidationError instead of only the first one.

Example

use Fynix\Rule;

$errors = Rule::password('password')
    ->length(12, 128)
    ->validateAll('abc');

This allows a form or API response to show all password policy violations together.

Structured errors

Each result is a ValidationError with a field name, message, machine-readable code, and parameters:

foreach ($errors as $error) {
    $payload[] = $error->toArray();
}

For complete DTO validation, ValidationHandler::validate() returns string messages by default. Pass flattenErrorToString: false when the object-level result should retain structured errors.

Object-bound values

Bind the rule to an object to validate a property without passing the property value manually:

$user = new User();
$user->password = 'abc';

$errors = Rule::for($user)
    ->password('password')
    ->length(12, 128)
    ->validateAll();

Use validateAll() for password policies, import validation, or API responses where showing every applicable issue is more useful than stopping at the first one. For complete DTO graphs, use ValidationHandler::validate() instead.
