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);

Equals

The specified fields must be equals.

new Validators\Equals($field, $field2, $error_message);

NotEquals

The specified fields must not be equals.

new Validators\NotEquals($field, $field2, $error_message);

Exists

Check inside a database if the column value exists or not.

new Validators\Exists($field, $error_message, PDO $pdo, $table, $key = '');

$pdo must be an PDO instance, $table is the table name. By default the key used in the table is the value of $field, but it can be override if the field doesn't have the same name in the database.

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".

$field can either be a string or an array of string to check inside a database if a value from several columns is unique or not.

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.
