Using filters from other classes within rules method in Yii 2?

Consider this code inside a model:

public function rules() {
    return [
        [['company_name', 'first_name', 'last_name'], 'sanitize'],
        //........
    ];
}

sanitize is a custom method inside the current class, which is:

public function sanitize($attribute) {
    $this->{$attribute} = general::stripTagsConvert($this->{$attribute}, null, true);
}

Now this method obviously will come in handy in many models so I don't want to keep repeating the same code in every model. Is there a way I can reference another class in the rules in place of the current sanitize method name which is binded to the current class?

Yes, it's definitely possible.

Create separate validator. Let assume it's called SanitizeValidator and placed in common/components folder.

Your custom validator must extend from framework base validator and override validateAttribute() method. Put your logic inside this method:

use yii\validators\Validator;

class SanitizeValidator extends Validator
{
    /**
     * @inheritdoc
     */
    public function validateAttribute($model, $attribute)
    {
        $model->$attribute = general::stripTagsConvert($model->$attribute, null, true);
    }
}

Then in model you can attach this validator like this:

use common/components/SanitizeValidator;

/**
 * @inheritdoc
 */
public function rules()
{
    return [
        [['company_name', 'first_name', 'last_name'], SanitizeValidator::className()],
    ];
}

Check the official documentation about custom validators here and there.
