Yii2 Calc Validator
===================

[](#yii2-calc-validator)

Math expression validator without using `eval()` for Yii2.

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

[](#installation)

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

Either run

```
$ composer require zhuravljov/yii2-calc-validator

```

or add

```
"zhuravljov/yii2-calc-validator": "*"

```

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

Usage
-----

[](#usage)

```
public function rules()
{
    return [
        // ...

        // Rule for checking an expression
        ['amount1', 'zhuravljov\yii\validators\CalcValidator'],

        // Rule for checking an expressions with saving result of calculation
        ['amount2', 'zhuravljov\yii\validators\CalcValidator', 'resultAttribute' => 'amount2'],

        // ...
    ];
}
```

After adding this validator, expressions can be used in forms.

For example:

- `12.80 + 3.50 * 2` - valid expression. Result: `19.8`.
- `(2 + 2) * 2` - valid expression. Result: `8`.
- `(2 + 2` - invalid expression.

This validator checks an expression and saves a result. And it can be used for currency fields or any numeric fields.
