PHP-Validate

PHP validation library. This is similar to Perl's Params::Validate. You can use it to validate anything, but most commonly it is used for validating input from HTML forms, fields while reading CSV files, function parameters, ORM arrays, etc.

Requirements:

• PHP 5.3.0 or newer

Usage:

All the classes contain PHP documentation, so you can start by reading the API documention.

Example:

<?php
require_once('lib/Validate/Validator.class.php');

function save_student_score(array $params) {
	$params = (new Validate\Validator(array(
		'specs' => array(
			'name'	=> array(
				'type'			=> 'string',
				'max_length'	=> 2,
				'max_length'	=> 30,
			),
			'birthdate' => array(
				'type'	=> 'string',
				'regex'	=> '#^[0-3]\d/[01]\d/\d{4}$#', // expect dd/mm/yyyy
				'after'	=> function(&$value) { // want yyyy-mm-dd
					if (is_string($value) && preg_match('#^(\d{2})/(\d{2})/(\d{4})$#', $value, $matches)) {
						$value = $matches[3] . '-' . $matches[2] . '-' . $matches[1];
					}
				},
				'optional' => true,
			),
			'score' => array(
				'types' => array('float', 'integer'),
				'max_value'	=> 10,
				'min_value'	=> 0,
			),
		),
	)))->validate($params);
	// Insert $params into database here.
}
	
$error = null;
try {
	save_student_score($_POST);
}
catch (Validate\ValidationException $e) {
	$error = $e->getMessage();
}
if ($error) {
	// display error message.
}
else {
	// display success message.
}
