Easiest Form Validation Library for PHP

When dealing with form submissions in PHP, validating and sanitizing user input is crucial to ensure the integrity and security of your application. Here's a simple library that can help you achieve this with ease:

FormValidator Class

The FormValidator class provides an intuitive and customizable approach to form validation and sanitization. Here's how it works:

1. Create an Instance

<code class="php">$validator = new FormValidator($validations, $mandatories, $sanatations);</code>

• $validations: An array mapping field names to validation rules (e.g., 'email' => 'email', 'phone' => 'number').
• $mandatories: An array of mandatory fields that must be present in submitted data (e.g., ['name', 'email']).
• $sanatations: An array mapping field names to sanitization rules (e.g., 'username' => 'string').

2. Validate an Array of Items

<code class="php">$validator->validate($items);</code>

3. Get Validation Script

<code class="php">$validator->getScript();</code>

This script can be used to add 'unvalidated' CSS class to invalid field elements while removing it from valid ones.

4. Sanitize an Array of Items

<code class="php">$validator->sanatize($items);</code>

Sample Usage

<code class="php">$validations = ['name' => 'anything', 'email' => 'email', 'message' => 'anything'];
$mandatories = ['name', 'email'];
$sanatations = ['message'];

$validator = new FormValidator($validations, $mandatories, $sanatations);

if ($validator->validate($_POST)) {
    $_POST = $validator->sanatize($_POST);
    // Save the data and display success message
} else {
    // Display the 'unvalidated' script to highlight errors
    echo $validator->getScript();
}</code>

This simple yet powerful library provides an effortless way to handle form validation and sanitization in your PHP applications.
