这是敏捷数据（https://github.com/atk4/data）的验证器插件。

它底层使用 https://github.com/vlucas/valitron。

使用方法

// add model fields
$model->addField('name');
$model->addField('age', ['type' => 'number']);
$model->addField('type', ['required' => true, 'enum' => ['dog', 'ball']]);
$model->addField('tail_length', ['type' => 'number']);

// add validator to your model
// also will register itself as $model->validator property
$v = new \Atk4\Validate\Validator($model);

// set simple validation rule for one field
// ->rule($field, $rules)
$v->rule('name', [ 'required', ['lengthMin', 3] ]);

// set multiple validation rules in one shot
// ->rules($array_of_rules) // [field=>rules]
$v->rules([
    'name' => ['required', ['lengthMin',3]],
    'age' => ['integer', ['min',0], ['max',99]],
    'tail_length' => ['integer', ['min',0]],
]);

// set validation rules based on value of another field
// if type=dog, then sets fields age and tail_length as required
// ->if($condition, $then_array_of_rules, $else_array_of_rules)
$v->if(['type'=>'dog'], [
    'age' => ['required'],
    'tail_length' => ['required'],
], [
    'tail_length' => [ ['equals',''] ], // balls don't have tail
]);

// you can also pass multiple conditions which will be treated as AND conditions
$v->if(['type'=>'dog', 'age'=>50], $rules_if_true, $rules_if_false);

// you can also set custom error message like this:
$v->rule('age', [ ['min', 3, 'message'=>'Common! {field} to small'] ]);
// and you will get this "Common! Age to small"

您也可以传递回调而不是规则数组。回调函数接收这些参数 $field, $value, $args, $data 并应返回 true/false。
