This validator solves value collisions for unique model attributes by adding incremental index to repeating values. E.g. `title` will become `title-1` if item with `title` already exists.

Such behavior may be useful for tasks like generating URLs and so on.

Installation
------------

[](#installation)

Install validator with Composer:

```
composer require --prefer-dist "herroffizier/yii2-attribute-index-validator:@stable"

```

Usage
-----

[](#usage)

Add validator to your model's rules array before `required` and `unique` validators (if any).

```
use herroffizier\yii2aiv\AttributeIndexValidator;

...

public function rules()
{
    return [
        [['attribute'], AttributeIndexValidator::className()],
        [['attribute'], 'required'],
        [['attribute'], 'unique'],
    ];
}
```

Validator has a few options to customize its behavior.

- `separator` sets separator between original value and index. Default separator is `-`.
- `startIndex` defines start index. Default value is `1`.
- `filter` defines additional filter to be applied to query used to check attribute uniqueness. May be either a string, an array or an anonymous function. In case of string or array `filter` value will be passed to `\yii\web\ActiveQueryInterface::andWhere()` method. In case of anonymous function its signature must be `function($query)` and instance of `\yii\web\ActiveQueryInterface` will be passed to it. Default value is `null`.
