Easiest Form Validation Library for PHP

In search of a straightforward PHP library that simplifies form validation tasks? Let's explore your options:

Custom Library Example

The user suggests a custom PHP class that incorporates predefined regex patterns and PHP's sanitization and filtering functions. This class, named FormValidator, provides methods for validating and sanitizing form fields. It checks fields against specified regex rules and returns validation results as well as error messages.

Usage Demonstration

Here's an example of how to use the custom library:

<code class="php">$validations = array(
    'name' => 'anything',
    'email' => 'email',
    'alias' => 'anything',
    'pwd' => 'anything',
    'gsm' => 'phone',
    'birthdate' => 'date');
$required = array('name', 'email', 'alias', 'pwd');
$sanatize = array('alias');

$validator = new FormValidator($validations, $required, $sanatize);

if($validator->validate($_POST))
{
    $_POST = $validator->sanatize($_POST);
    // now do your saving, $_POST has been sanatized.
    die($validator->getScript()."&lt;script type='text/javascript'&gt;alert('saved changes');&lt;/script&gt;");
}
else
{
    die($validator->getScript());
}</code>

The provided library offers a simple and customizable validation solution, but keep in mind that you may need to modify the regex patterns and filtering rules to suit your specific validation requirements.
