Usage

Your data must be an array, it can be form data, a decoded JSON string or whatever. Each different validator is a simple standalone class. But we use a main class to pass through every validators. Let's see a basic example:

use SimpleValidator\Validator;
use SimpleValidator\Validators;

$data = array('field1' => '1234');

$v = new Validator($data, array(
	new Validators\Required('field1', 'field1 is required'),
	new Validators\Integer('field1', 'field1 must be an integer'),
));

// Validation error
if (! $v->execute()) {

	print_r($v->getErrors()); // Get all validation errors
}

Validators

Alphanumeric

Allow only letters and digits.

new Validators\AlphaNumeric('column name', 'error message');

Email

I use the same validation method as Firefox: http://hg.mozilla.org/mozilla-central/file/cf5da681d577/content/html/content/src/nsHTMLInputElement.cpp#l3967

So email address like toto+titi@domain.tld are allowed.

new Validators\Email($field, $error_message);

Integer

Allow only integer, but also strings with digits only.

new Validators\Integer($field, $error_message);

Length

Allow only strings with a correct length.

new Validators\AlphaLength($field, $error_message, $min, $max);

Numeric

Allow float, integer and strings with only digits and dot.

new Validators\Numeric($field, $error_message);

Range

Allow only numbers inside the specified range.

new Validators\Range($field, $error_message, $min, $max);

Required

The specified field must exists.

new Validators\Required($field, $error_message);

Unique

Check inside a database if the column value is unique or not.

new Validators\Unique($field, $error_message, PDO $pdo, $table, $primary_key = 'id');

$pdo must be an PDO instance, $table is the table name and by default the primary key is "id". If the primary key value is not null, we don't check the uniqueness of the column for this row. It's useful if you perform validation for an update.
