This is a simple validation engine written in PHP OOP for fun. If you need a robust PHP validator I recommend [this one](https://github.com/Respect/Validation).

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

[](#installation)

Install the package using *Composer*:

```
$ composer require pbrus/validation-engine=dev-master
```

Then go to the `validation-engine/` directory and make `dump-autoload`:

```
$ cd vendor/pbrus/validation-engine/
$ composer dump-autoload
```

If don't know what *Composer* is, see the [simplified PHP installation](https://github.com/pbrus/astro-quiz#installation).

Usage
-----

[](#usage)

Define a validator and set its labels (here `username` and `id`):

```
$validator = new ValidationEngine();

$validator->setLabels(array(
    'username',
    'id'
));
```

In the next step set constraints for each label:

```
$validator->setConstraints('username', array(
    new NotEmptyValidator(array(
        'notEmptyMessage' => 'Field username must be filled out'
    )),
    new LengthValidator(array(
        'minLength' => 3,
        'maxLength' => 25,
        'lengthMessage' => "Field username must contain 3-25 letters"
    ))
));

$validator->setConstraints('id', array(
    new NotEmptyValidator(array(
        'notEmptyMessage' => "You must type your ID"
    )),
    new LengthValidator(array(
        'minLength' => 10,
        'maxLength' => 10,
        'lengthMessage' => "Field ID must consist of 10 integers"
    ))
));
```

Then we can validate data:

```
if (!$validator->setFields(array(
    'username' => 'John',   // not validated: 'Jo'
    'id' => '9876543210'    // not validated: '123'
))
) {
    echo $validator->getErrorMessage();
}
```

If you encounter any problems, please see the demo file `index.php`.
