PHP Validator

Introduction

This is a simple data validator originally developed for an application I am developing. Seeing as though I found this super helpful I decided to make it available for you guys.

How to use

Before I show you how to use this you need to use the john-crossley/db-class I built. This is so you can ensure data is unique.

Let's move on…

<?php
// Require the validator
require 'DB.php';
require 'Validator.php';

// Create a new instance of the validator
$v = new Validator();
?>

Right so what do we need to validate?

<form action="test.php" method="POST">

  <p>
    <label for="username">Username: </label>
    <input type="text" name="username" id="username">
  </p>

  …

Tell the validator we would like to validate the username field like so:

…
$v = new Validator();
$bannedEmailExtensions = '@example.com @domain-name.com @fake.co.uk';
$rules = [
    'username'       => ['required', 'min:3', 'max:62', 'unique:user'],
    'password'       => ['required', 'min:8'],
    'password_again' => ['required', 'match:password'],
    'email'          => ['required', 'valid_email', 'unique:email', 'banned:'.$bannedExtensions]
];

As you can see in the $rules array we specify several rules for the username input field those are separated by the | we have require, min, max and unique as mentioned before you may only use the unique if you have required the DB.php file.

Next we need to tell the Validator about these rules. We do this like so

$v->make($_POST, $rules);

Note how I'm passing in the POST array? Any data that needs validating should be formatted as such; array('username' => 'admin', 'password' => 'myPass123' …
