Yii2: Dynamic max value validation rules

How to add customized validation for a field in yii2.? Textbox value should not exceed a table field values from current model. Is there any way to add new rule from controller?

Ex: $model->f1 should be lessthan or equal to $model->f2.

I got some points with dynamicmodel. But i have only one field to check.

it should work on client side also.

is there anyway to add custom rule from controller or in activeform?

Thanks.

Add this to your validation rules in model to ensure f1 value is <= f2. 

[
  // other validation rules
  ['f1', 'compare', 'compareAttribute' => 'f2', 'operator' => '<='],
]

You Can use CompareValidator compareValue property as :-

 public function rules()
{
    return [
       // Your Validation rules as
        [
            'f2' ,
            'compare' ,
            'compareValue' => ArrayHelper::getValue($this , ['oldAttributes' ,'f1']),
            'operator' => '<=',
        ]
    ];
}

Model f1 value which is saved in database must be greater than f2 filled by user
