BetterValidation

Simple clean validation library. Very new, wrote it after being both frustrated and inspired by Codeigniters validation library and PHP Validation by Benjamin Keen.

BetterValidation may sound a little conceited but I really only mean I built on some good ideas and made something that met my own requirements much better. Was only a working title but I couldn't think of anything else to name it and I wanted to offer it to the community so ...

Usage

The current usage is quite similar to both Codeigniter and PHP Validation. Unlike Benjamin Keen's implementation I have nether required or allowed error messages to be passed in with the rules. This and any HTML formatting is left to the rest of your program to handle as a validation class is not the right place for them.

Currently you would specify rules in an associated array:

$myrules = array('name'           => 'min_length[4]',
                 'username'       => 'required|min_length[4]|max_length[128]',
                 'password'       => 'required|min_length[4]',
                 'passconf'       => 'required|matches[password]',
                 'email'          => 'required|valid_email',
                 'account_number' => 'required|regex[/[\d]+\-[A-Z]{4}\-[\d]{2}/]');

Then pass the array to a new ValidationRules instance:

$rules = new ValidationRules($myrules);

You can then run the validation:

$rules->validate($data, false);

Here I have assumed you have an associated array of data in a variable called $data, something similar to the following:

$data = array('name'           => 'me',
              'username'       => 'myusername',
              'password'       => 'MyPåssw00rd',
              'passconf'       => 'MyPåssw00rd',
              'email'          => 'user@example.com',
              'account_number' => '1-ABCD-23');

This example will fail validation, here is what output you will get in order to handle your response to the user:

array(1) {
  ["name"]=>
  array(1) {
    [0]=>
    string(10) "min_length"
  }
