Build Status

📖 Documentation

💿 Installation

php-validator can be installed via composer, just execute the following command in your project root

composer require aubind97/php-validator

Or you can add the following input in your composer.json file.

"require": {
  "aubind97/php-validator": "^1.0"
}

📚 Usage

Make sure to use composer autoloading to load the package
Be sure to add the use statement or add the namespace before Validator

Using php-validator in your projet is super simple, here is an example

$validator = (new Validator($_POST))
  ->email('email')
  ->length('firstname', 2, 100)
  ->length('lastname', 2, 100)
  ->length('nickname', 2, 100)
  ->required('email', 'firstname', 'lastname');

We can validate $_POST or any other arrays

Then, you can check for validation like this

$validator->isValid();

If there are errors, you can get errors messages with

$validator->getErrors();

Optionnally, you can pass an associative array for parameters internationalization. The key is the attribute name you passed in the Validator constructor, the value is the translation (FR example below).

$validator->getErrors([
  'firstname' => 'prénom'
]);

Advanced features

You can add a filter at the validator creation, to discard not needed arguments

$validator = new Validator($_POST, ['firstname', 'lastname']);

You can also create validator with many rules, to validate all params of a model for instance, and apply rules only is the params are in the array params given at the construction

$validator = new Validator($_POST, ['firstname', 'lastname'], true);

Finally, you can pass IETF locale for internationalization (currently supports en-US, fr-FR)

$validator = new Validator($_POST, ['firstname', 'lastname'], true, 'fr-FR');
