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

[](#installation)

The preferred way to install this extension is through [composer](http://getcomposer.org/download/). Either run

```
 composer require --prefer-dist long399/yii2-math-captcha

```

or add

```
"long399/yii2-math-captcha": "~0.1"
```

to the require section of your `composer.json` file.

Available operations
--------------------

[](#available-operations)

1. Addition.
2. Subtraction.
3. Multiplication.

Default addition or subtraction operation will be used randomly.

Usage
-----

[](#usage)

controller:

```
public function actions()
{
    return [
        ...
        'captcha' => [
            'class' => \long399\captcha\MathCaptchaAction::class,
            'fixedVerifyCode' => YII_ENV_TEST ? '399' : null,
            'minLength' => 0,
            'maxLength' => 1000,
        ],
        ...
    ];
}
```

model:

```
class MyModel extends \yii\db\ActiveRecord
{
    public $captcha;
    ...
    public function rules()
    {
        return [
            ...
            ['captcha', 'captcha', 'captchaAction' => '/site/captcha'],
            ...
        ];
    }
    ...
}
```

view:

```
...
echo $form->field($model, 'captcha')->widget(\yii\captcha\Captcha::class, [
    'captchaAction' => "/site/captcha",
    'template' => '{image}{input}',
]);
...
```

If you want to use only expressions with a subtraction operation e.g., then you need to set the **operations** property accordingly in the description of the action in the controller:

```
public function actions()
{
    return [
        ...
        'captcha' => [
            'class' => \app\components\actions\MathCaptchaAction::class,
            'fixedVerifyCode' => YII_ENV_TEST ? '399' : null,
            'minLength' => 0,
            'maxLength' => 1000,
            'operations' => ['-'],
        ],
        ...
    ];
}
```

Expressions with multiplication
-------------------------------

[](#expressions-with-multiplication)

If you want to use also expressions with a multiplication operation, then you need to set the **operations** property accordingly in the description of the action in the controller:

```
public function actions()
{
    return [
        ...
        'captcha' => [
            'class' => \app\components\actions\MathCaptchaAction::class,
            'fixedVerifyCode' => YII_ENV_TEST ? '399' : null,
            'minLength' => 0,
            'maxLength' => 1000,
            'operations' => ['+', '-', '*'],
        ],
        ...
    ];
}
```

Three kinds of expressions can be generated:

1. Expression with multiplication.
