# Validator

Data validation composer package.

## Installation

Install using composer.

```
composer require codesvault/validator
```

<br>
<br>

## Usage

```php
$validator = Validator::validate(
    [
		'username'	=> 'required|stringOnly',
		'full_name'	=> 'stringWithSpace',
		'password'	=> 'required|min:8',
		'email'		=> 'required|email',
    ],
);
```

<br>

It'll get data from `$_REQUEST` by default. But you also can pass data as second parameter.

```php
$validator = Validator::validate(
	[
		'username'	=> 'required|stringOnly',
		'full_name'	=> 'stringWithSpace'
	],
	[
		'username'	=> 'abmsourav',
		'full_name'	=> 'Keramot UL Islam'
	]
);
```

<br>
<br>

## Handling Errors

If any data is invalid then `error` method will return error messages array. Otherwise it'll return false.
<br>
`getData` method will return validated data array.

```php
$error = $validator->error();
if ($error) {
	return $error;
}
$validator->getData();
```
