Validator
=========

[](#validator)

The Validator validates data against user-defined rules.

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

[](#installation)

```
composer require webiik/validator
```

Example
-------

[](#example)

```
$validator = new \Webiik\Validator\Validator();

// Add input to validate and input validation rules
$validator->addInput('meow', function () {
    return [
        new \Webiik\Validator\Rules\StrLenMin(5, 'Err: Input is shorter than 5 chars.'),
        new \Webiik\Validator\Rules\StrLenMax(10, 'Err: Input is longer than 10 chars.'),
    ];
}, 'greeting');

// Validate all inputs and eventually get array of all invalid inputs
$invalid = $validator->validate(); // Array ( [greeting] => Array ( [0] => Err: Input is shorter than 5 chars. ) )
```

Adding Inputs For Validation
----------------------------

[](#adding-inputs-for-validation)

### addInput

[](#addinput)

```
addInput($input, callable $rules, string $name = '', bool $isRequired = false): void
```

**addInput()** adds an input for validation.

**Parameters**

- **input** input value
- **rules** callable that return an array of validation rule objects
- **name** optional input name. This name is used as input index in validate() result.
- **isRequired** optional. Indicates if input is required or not. Empty optional inputs are always considered as valid.

```
$validator->addInput('meow', function () {
    return [
        new \Webiik\Validator\Rules\StrLenMin(5, 'Err: Input is shorter than 5 chars.'),
        new \Webiik\Validator\Rules\StrLenMax(10, 'Err: Input is longer than 10 chars.'),
    ];
}, 'greeting', true);
```

Validation Rules
----------------

[](#validation-rules)

#### Write Custom Validation Rule

[](#write-custom-validation-rule)

You can write your custom validation rule. The only thing you have to do is to implement [RuleInterface](Rules/RuleInterface.php). Look at existing [implementation of RuleInterface](Rules/Equal.php) to get better insight.

#### Available Validation Rules

[](#available-validation-rules)

```
// Check if input is === $val
Equal($val, string $errMsg = '')
```

```
// Check if input is >= $min and = $min and = $min
StrLenMin(int $min, string $errMsg = '')
```

```
// Check if input length is validate();
```
